The Building of Silver Stage Two: Heating, Insulation and Flooring

Since the last post, it has been very slow progress with the van build but in the last week we have finally seen significant change. Why slow? Well we have been doing other things. Dave has spent a couple of days helping Jason build a “rum shack” in his garden.

We also had a few days away in the van on a beautiful campsite in Bishop’s Castle, Shropshire.

We had a quick but wonderful trip to visit Dave’s family…

A typical British summer picnic in the rain

…and and I spent 5 days with mine in Lichfield, as my nephew prepared to leave for uni in Glasgow.

We also had a great day out on the motorbikes in mid-Wales with Jason and Ali in stunning scenery.

I have been busy writing my other blogs and had a couple of articles published in magazines and I have been working on the garden. So we have no doubt been occupied but, in truth, there has still been plenty of time for the van. I can offer up no reason as to why the build slowed to a snail’s pace. After fitting the windows, we just seemed unable to gain momentum. However, thankfully that seems to have changed over the last few days and we have now turned a corner. So where are we up to?

One of the most important tasks in converting a van for full time living is to ensure it is warm. We plan to use Silver in Scottish or alpine winters so it needs to be cosy and free of condensation. This means that it needs to be insulated and also have heating installed for the coldest nights. Dave began the process of installing heaters for both water and air about two months ago. This involved a lot of discussion with Jason and pontification which, I have learned over the last 27 years, is what happens when you put two engineers together. I can sustain interest in the conversation for about 20 minutes before giving up the will to live and drifting into the kitchen to wash up or sweep the floor or something equally more interesting. Eventually, after considering al the options. they concurred that we would have gas heaters fuelled by a propane tank installed underneath the van. The waste water tank also goes under the van so they had to make sure there was space for everything and that it could all be installed safely. This also involved cutting holes in the floor of the van in order to bring the heaters partially inside.

All of this seems to have taken many weeks to get right as the correct brackets and different bits and bobs (technical term) had to be ordered and installed. As with most things on a van conversion, you don’t get it right first time so there was inevitable delay as Dave sourced or crafted the right accessories. However, after weeks of delay, we finally completed installation of the heaters last week and brought them through into the van ready to install ducting/pipes at some point in the future and so insulation and the laying of an impermeable vapour barrier (i.e. plastic sheet) could finally be tackled.

Insulation is a real pig of a job. When asked which job they would least like to do again, many van lifers mention insulation. The floor, walls and ceiling all need to be insulated, with either 50mm insulation board or soft insulation, the same as you use in your loft, and then a vapour barrier is secured. Now our van in only just about tall enough for Dave to stand up in metal to metal. If we laid down 50mm of insulation on both the floor and ceiling, as most do, it would be 10cm too short for Dave, so this is not an option for us. It took a while to decide how to resolve this but we decided to add 25mm strips of insulation on the floor between the ridges so there would at least be some insulation but no loss of height (as seen in the photo above). The ceiling will be fully insulated so we will lose 4-5cm in all. The floor is not fully insulated and it remains to be seen if this will be a problem with cold coming up through the floor but with a gas heater installed, I am assured it will stay warm. It took Dave a while to cut and secure all the strips of 25mm insulation board and in the meantime I made a start with insulating the walls, which turned out to be much tricker than we both expected.

Dave cutting 25mm strips of insulation board

Insulation board is flat but the walls of a Sprinter are not. They come with various indentations, where windows can be added, and other channels and gulleys, which make installing flat insulation board very challenging. After one attempt to cut and install the board, which took up a whole morning, we both agreed that our work was not up to standard and needed to be redone. This was hard to accept, as the board isn’t cheap but mostly because the work is filthy and not something you want to do twice if it can be avoided. Sawing or cutting polystyrene is easy enough but it creates bits and dust that get everywhere, including onto your chest if you forget to wear a mask, and on a windy day it blows around the garden and over into the neighbours’ gardens. Our back lawn has a white tinge, almost as if it has lightly snowed. I have no idea how to get rid of it and it might be there forever.

While accepting our work was shoddy, we were stuck as to how to make the board fit properly so we went back to the trusty YouTube videos to learn what others did. No-one seems to show the whole process, I suspect that’s because there is always an element of bodging involved that they don’t want subscribers to see. We picked up some tips though and started again the next day. I must admit that I had partly lost interest by then but Dave was dogged and did a stellar job sculpting and carving the board to fit the larger spaces.

The second tool…
…the third tool
A perfect fit

Around this time I departed for Lichfield for the best part of a week and when I returned Dave had completed all of the larger sections of wall insulation. That was not strategic on my part but worked well for me.

Insulation board in place just in time for our short break. We could not take a guitar camping on the motorbike.

Immediately upon my return to Wales, the weather became unexpectedly good so we decided to get away in Silver for a few days. Before we left we installed a sun canopy. Like everything else, the decision about which canopy to buy was not an easy one. We really wanted a Fiamma retractable awning, which is fitted to the van permanently and pulls out and retracts as needed. However, they cost around 800 quid and weigh 50kg. Although they are very popular, we decided that this was out of the question for us. We eventually settled on a Vango Sun Canopy, which we bought half price on eBay for 70 quid plus the cost of the awning rail which we had to glue to the roof of the van.

Installing the awning rail

We now have a 4m awning which gives both shade and protection from the rain at a bargain price. It does have to be attached to the rail each time we set up camp, which involves Dave climbing on the roof but we are happy enough with the choice we made.

We had a great few days away. Most people would view sleeping in the back of a van on an inflatable mattress as quite squalid (and from the photo of the inside of the van posted above, you can see that it was) but it felt like the height of luxury when compared to a tiny tent and motorbike. We could take everything we wanted, boxes of stuff. We had a comfy bed. As you get older Thermarest mattresses lose their appeal, although we found that an air bed does not keep the cold out in the same way as a closed cell foam mattress. We had chairs and a table rather than sitting on the ground.

We also had a fire pit for the chilly evenings.

We loved it all and it made us realise just how great it will be when Silver is eventually finished.

We returned from the trip with renewed purpose, determined to make more progress so we could enjoy more short trips away in the coming weeks (this was before we were placed into local lockdown but more about that later). We finished fitting the heaters under the van..

I found much to my surprise that I love being underneath the van…who knew?

and insulating the floor, allowing us to put down the vapour layer and restore the original floor as a base for the vinyl flooring. It turned out that my sewing skills in making 2D materials fit a 3D body finally came in handy and I was able to lay the vapour barrier, which is a sheet of plastic, around and over the wheel arches without too much difficulty.

We then set to completing the insulation of the walls using a soft insulation material made from recycled plastic bottles, which is much nicer to work with than the traditional glass fibre stuff and more environmentally friendly. Both walls were then covered with more sheets of plastic, definitely a two-man job but fairly satisfying to complete.

Silver was now ready to have walls installed. The nature of these walls has been the topic of much debate. Factory built motorhomes use board covered in wallpaper to achieve a professional finish, whereas the use of what is called 4-way stretch carpet on top of plywood is much more popular with VW owners and converters. However, the new breed of millennial van lifers much prefer to finish their walls with tongue and groove panels, which give a nice finish when painted or varnished and are easy to install. The drawback is that they are heavy. A Sprinter van has a maximum legal weight of 3.5 tonnes. Exceeding this weight, once the build is complete, and the mass of two adults, all their stuff, fuel and water is added, not only impacts on the safety of the vehicle but is liable to a hefty fine and impounding of the van. Many campervan owners dismiss this issue as not important but as motorcyclists and old duffers, we are always safety and legal first so we have committed to keep the build as light as possible. This precludes us from using tongue and groove and leaves us with the plywood option to create our walls and ceiling.

We discovered a couple of weeks ago that there are companies that sell ready-cut ply linings for Sprinter vans at a very reasonable price so we took delivery of the 6mm ply panels ready to install. The panels are not perfect but they are good enough and as 6mm ply retains some flexibility, they fit snug to the shell of the van without wasting crucial space.

We still have to decide what finish we will use but, given the visible joins between the panels and the visible screw heads, we are unlikely to paint them and more likely to use a neutral wallpaper. The jury is still out on that one.

With the walls installed we were ready to lay the flooring. We decided on industrial sheet vinyl flooring which is non-slip, waterproof and very hard-wearing. The design we chose comes with sparkly bits in show catch the light when the sun shines and prevents it from looking too much like the stuff used in mental hospitals. What we hadn’t bargained for is how hard the vinyl is to cut, especially when cold. It seemed to defeat the ordinary Stanley blade and the special hook-shaped Stanley blade but we soon discovered with the help of Google that heating the flooring with a hairdryer softened it and made it easier to cut.

I have laid vinyl a few times before but this was much harder to manage and manipulate and took us several hours to get it how we wanted it. It is great to see the first decorative finish of the van take shape though and the first indication that it is more than just a cargo van.

Our next job is to batten out the layout of the van interior, starting with the bed and then the shower, seating area and kitchen. Work begins on this tomorrow. But you haven’t insulated the ceiling yet, I hear you say. Well there is a reason for that. Before insulating the ceiling, we need to install a pair of MaxxFans in the roof to both suck and blow air, and keep us cool and ventilated. One of these fans will go directly over the shower cubicle, as there is already a hole in the roof and a small fan installed in that area and we do not want to cut an extra hole. However, we need to ensure that the placement of the MaxxFan is 100% accurate over the shower, rather than part in and part out of the cubicle but we cannot do this until the shower cubicle is battened out. This means that installation of the MaxxFans and insulation of the ceiling will take place after battening out the layout. This is a bit arse about face but was the best solution we could come up with. As I said, nothing is straightforward with a van build.

The MaxxFans have been sitting in the garage for 2 months but in preparation for the next exciting stage of the build we also now have the shower tray, Nature’s Head composting toilet, fridge and cooker purchased and taking up space in the bungalow.

I have also bought the materials to make blackout, insulating blinds for the windows and the foam for the seat cushion, which I will cover with old curtain fabric. So there is plenty to be getting on with as the nights draw in and the days get chillier. Hopefully I will report back more quickly next time as we continue to make more rapid progress.

Since Thursday, we are longer allowed to leave the county or mix indoors with anyone that we do not live with, under the new COVID restrictions for North Wales. It seems a bit daft that we cannot legally visit the garden of friends who live 20 minutes away in a different county but people from England can travel here freely. We don’t have a major DIY store within the boundaries of our county so that may pose problems in the coming weeks. Dave is also very upset that while he can visit Toolstation in Denbigh, he can no longer go to Screwfix in Mold, which is only 10 minutes further away…how will he cope? More importantly, a much looked forward to visit from Dave’s family to celebrate a birthday has also had to be cancelled. Nevertheless, we support the measures taken by the Welsh assembly to keep us safe and we will abide by the new rules despite the confusion and inconsistencies. We like our own and each other’s company and we have plenty of hobbies and interests to keep us occupied and plenty of food in supply in case things get worse. We also have the whole winter to finish and dream about using our van again.

The Building of Silver Stage 1-Strip Out and Windows

Image

It’s been about a month now since we brought (Son of) Silver home and during that time we have been very busy planning, ordering and doing. In between van stuff we have had many lovely visits from our local friends and a visit from my family, some trips out on sunny days to Llandudno, Llangollen and Chester as well as putting in work on the vegetable garden. All in all, this retirement business is pretty amazing. The only disappointment is that Dave’s family are in local lockdown in Lancashire and we have not been able to see them yet.

We are getting used to owning a van as our primary vehicle. It is massive but actually quite easy to drive, although I haven’t tried reversing it yet. It takes up two whole spaces end to end on a carpark and we are already developing an intimate knowledge of where we can and cannot park in most towns within a 30 mile radius.

There’s a lot to be done to turn the van from an empty silver box into a comfortable and functional home that we may well live in for 2-3 years or more. We started by stripping out the lining back to the metal and removing the bulkhead to allow access from the cab into the back. What I am learning already, is that regardless of how many tools you have in the garage, you seldom have the correct tool in the right size to complete the job at hand. We have become regular visitors to a range of tools shops that I call Machinemartfixstation-those of you who are into tools will know the shops I mean. Fortunately, we have all the major tool shop chains within a 20 minute drive, which in rural North Wales is considered to be “around the corner” or “just down the road”.

The removal of the final bolts that secure the bulkhead required the only size of a particular tool, of which we had many sizes, that we did not have, so my first experience of working on the van comprised of spending an hour undoing a load of bolts, only to have to do half of them up again to resecure the bulkhead so we could drive to Machinemartfixstation to acquire the right tool. I suspect this may become a familiar pattern.

In his previous life, Silver was a Mercedes lease van working for a contractor to the NHS and he came with a heavy, steel ramp to load wheelchairs into the back. We were able to sell this on Ebay for a few hundred quid and enjoyed an hour in the company of Compo and Clegg from Last of the Summer Wine who arrived from Sheffield to collect it. Dressed in baggy singlets to make the most of the sunny weather, these septagenarians regaled Dave and our visitors with their tall stories, while they drank tea at an annoying leisurely pace before setting off for the four hour drive home. Having lived abroad for 20 years, I love these incidental encounters with people who speak the same language (well almost), that I really missed.

It is unfortunate that when converting a van, one of the first jobs you have to complete is one of the trickiest, fitting the windows. Many “stealth” vanlifers who park up in towns each night forgo windows to maintain the appearance of being a normal, commercial vehicle. This means light sources are limited to the windscreen and any roof fans or skylights that they install. We decided to install windows in the sliding door and barn doors at the back. We ordered these from Van Pimps at a very reasonable price and decided to fit them ourselves as most vanlifers seem to. We spent a few days watching as many Youtube videos as we could of both professionals and vanlifers fitting windows. There is no one right way apparently so we decided on a scheme of work combining the best of what we had learned. We were a bit thrown when we discovered that our Van Build Guru, the ever sensible Greg Virgoe, did not fit his own windows but engaged the services of Glass4Vans, but we rallied and pressed on, after getting a last minute quote for professional fitting of 300 quid.

The thought of cutting a hole in the side of your van is pretty scary and I must admit that the stress of the day actually made me quite ill and almost spoilt the celebratory trip to the chippy that evening. However, I rallied when I saw that our lovely chippy man had given me free batter bits, or scraps as they call them up north to go with my chips, peas and curry sauce.

Our first local chippy since 2005

Although Dave and I have been a couple for 26 years, we have never built something together, so we are experiencing something new. I am glad we waited until now as we are older, calmer and more patient with each other than we were in the past. Back in the early days, we couldn’t even put a tent up together without a blazing row and even to this day, Dave erects the tent on his own while I unpack the rest of the gear. It seems we have mellowed though and we got through a whole day of window fitting without a harsh word spoken. Now that is progress.

Vans come with recesses where windows are intended to go and the glass sits on top of those recesses, bonded to the metal, so it is not a question of cutting an aperture to the exact size of the glass, where 1mm could make the difference between the windows fitting or not. Once I realised this, it seemed less scary. However, we are both keen to do a good job. We want our van to look professional and not like a product of Odge Bodge and Codge Ltd. so we took our time, hoping to get it right. We started with the side window as the back windows, although smaller,  have to be done as a pair, to ensure they line up correctly.

The first stage was to remove the metal reinforcement from the window recess with an angle grinder. This involved a lot of noise and sparks and a quick cycle down to the builders merchants after 5 minutes of trying to cut using a grinding disc, to buy a cutting disc (see my earlier comment abut never having the right tools in there garage).

Once the reinforcement was off, we made a rough cut of the aperture with a jigsaw.

thumbnail-32

The hard part is getting the final cut the right size, as the recess that guides you is on the inside of the van but you have to cut from the outside. Professionals use special tools like electric shears that allow them to work from the outside while following the recess on the inside, while amateurs tend to create a template that they draw round on the outside of the van with a marker pen and then follow with the jigsaw. We came up with our own, more accurate, method which was to drill a number of holes from the inside following the line of the recess and then join these holes up with a marker pen on the outside. We drilled more holes around the curves to ensure they were accurate. This worked really well-mostly.

thumbnail-31

We then applied Hammerite to the cut edge to rust-proof it and had some lunch while we waited for this to dry.

Once the final cut was done, we thought the worst was over but this was not the case. There as more stress to come. We cleaned the window and used what is called Window Activator-no idea what this is or what it does but it comes as a little wipe in a sachet with the fitting kit. The best part of this stage was lying a large sheet of bubble wrap on the kitchen floor to receive the window and then walking over the bubble wrap in heavy boots. What a great and terrifying noise it makes – try it. We then had to apply glass primer to both the edges of the glass and the metal. This dripped a bit in a way that it did not on the professional videos and got all over our hands as we stupidly did not use the plastic gloves provided. Ridiculously we made the same mistake again when we fitted the rear windows three days later.

thumbnail-29

The glass bonding comes in tubes and is applied using a mastic gun. When Dave pierced the tube with a screwdriver, he did not pierce the whole thing and consequently struggled to squeeze the bonding out of the tube onto the metal-rookie error. We thought this would be the easy part-the professionals make it look very straightforward-but it was actually really hard to apply the bonding all around the large aperture in one smooth line.  Dave’s arms were aching from squeezing the bonding through the inadequate hole. Although we knew that the bonding does not form a skin for an hour, there was a sense of panic to get it done as quickly as possible.

thumbnail-39

Finally, we offered up the window to the aperture and pressed it on. I was left holding on the window with both hands while Dave, seemingly at a snail’s pace, cut and applied the tape to hold it while it dried.

thumbnail-37

It looked great and we felt really proud of our work…briefly.

From the outside it looked amazing and completely professional. Inside was a different story though, We realised on closer inspection that we should have cut the aperture to be completely  flush with the inner skin of the window recess. While we had done this on the most part, some areas of the aperture had 2-3mm of extra metal that should not be there. We presumed this would be covered by the rubber trim that had been supplied for this purpose. However, when Dave came to apply the trim it would not go on evenly over both skins and definitely had an air of Odge, Bodge and Friends about it, with a wavy finish. We removed the trim and found it went well over just the cut edge of the inner skin leaving unfinished edges on the outer skin where we had removed the reinforcement with the angle grinder. We decided to call it a day and take a walk to the chippy. Tomorrow was another day.

After 24 hours of recriminations about the standard of our finish, I remembered watching our hero Greg Virgoe applying his window trim, after the professional fitted his glass, so I went back and rewatched the video. He refers to using 9mm trim to ensure it goes over both skins. We had 6mm trim. My superior and obsessive internet search skills came into play seeking out a trim that would work for us. We ordered some and waited but sadly when it came it didn’t fit.  However, I realised when examining photos of other vans on Pinterest that most people build a window frame around their windows to give a nicer finish so the trim does not show. So I have moved on and stopped worrying about it. We took the weekend off in between fitting the side and rear windows. The weather has been great so we enjoyed the rare Welsh sunshine and moved on to discuss the next stage of the build. On Monday we returned to window fitting, older and wiser. This time we were faster and it was much less stressful. We used the right disc on the angle grinder, made sure to cut the apertures flush with the outer skin, we pierced the bonding tube properly and found that the trim went over both inner and outer skin to give a perfect finish as there gap between the skins is less on the rear windows. However, we did apply a bit too much bonding on the offside window, a bit too close to the edge so we have some trimming to do with a Stanley knife when it is completely set. No harm done though.

thumbnail-26

It’s great to have the windows in. They look so cool from the outside and they bring in much-needed light inside the van. So next we focus on installing the electrics and solar and gas systems. We have a heavy shopping list of expensive items for this. We also ordered the roof fans yesterday which are out of stock till the end of the month due to the huge demand. It seems the world and his dog are building a campervan this summer.  We also have to make a decision about the canopy/awning, which needs to be installed before the solar panels go on the roof. I am still in disbelief that a wind-out canopy costs around 700 quid, campervan accessories are so expensive but more about that next time.
