Single glazed vans

Is it poss to double glaze autosleeper vans any ideas thanks geoff

May I ask why?
In summer I’ve found the single glazing more than adequate and in winter I’m assuming you would have the heating on, we’ve never found the single glazing an issue.

The glass may not be where most heat is lost. The ventilation around the roof vents and the fridge may be more significant, particularly if the cab heater is not left in the recirculate position overnight.

Pulling down the fly screens would have a similar insulating effect to secondary glazing I would think. As DBVWT says never had a problem with single glazing on our 2014 WXL, we tour in UK every month from March to November and use as day van over winter

thanks for the replies, nice to get some idea from folk who use their vans, and doesn't look like its a problem to me, the vans are well thought out ,my favourite upto  now is the harmony nice and small with toilet and shower amazing for a swb ,van nice and compact and utilising all the space very well, ideal for 2 people and can get where the bigger vans struggle thanks everyone cheers geoff

Common to all vans, be they coach built or van conversions, the biggest heat loss is through the cab widows and windscreen. This can be seen by condensation in the mornings.
The easy remedy is a good quality insulated exterior cover. It makes a vast difference, and also keeps the van cool when parked up on hot days, remember them??

The silver screen we bought for the Duetto came with internal screens for the side and rear doors at no extra cost from Silverscreens. As I said elsewhere the insulation was not the best so silver screens and new curtains with insulated lining helped a lot.

I was concerned about the single glazing in A/S PVC's before we bought but so far, having used the van in February and March, we have not had a problem. My concern was more specifically condensation rather than heat loss, but we have not had any issue at all with that, even on the windscreen. The level of condensation depends a lot on how you use the vehicle/boat/house. Burning propane on un-flued appliances produces a lot of humidity (and toxic fumes!). One of my first jobs (after reducing the rattles) was to fit an inverter and an upgraded charging/battery system so we now cook almost exclusively electrically, which has rendered the oven/hob pretty well redundant.

Our 2004 Symbol had the 'traditional' style plastic caravan type windows with a silver pull up/down element inside. No condensation and kept the warmth in. Our current 2017 Symbol is very bad for heat loss and condensation on the windows. The blinds cassettes no longer have the silver element either. Yet another backwards step in our opinions and experience.

So with the window open shows silver to the outside[You must be registered and logged in to see this link.]

I am obliged to you glyne lock. I was totally unaware of this. However, the window areas are still cold do not retain heat as well as the last wagon and suffer condensation both side (ns & OS). In the light of this new discovery, I wonder why the foil is less effective. I am also going to add curtains as per the last Symbol. It's a cleaner arguably more modern look without and less fussy but in our opinion, less cozy and I think they will help heat loss. The gap on the rear doors is dreadful for leaking heat. We don't have the later central strip to cover the split, so I am going to curtain the rear too.

I don't have the rear door central strip either but I don't have any draught there at all. I've also got internal silver screens for the rear door windows and not got fitted blinds there. As an older van (2010) we don't have the front screen concertina blinds but have curtains , as we also have on the sliding door window. We rarely have any condensation on any of our windows.

Zero problems
Zero condensation
Amazingly quiet too....

I have posted my mod on a picture above this makes the glass windows much warmer and when you sit by them don't get the cold from the glass
the insulation done by A/S is very basic as the heater works so good gives the grade to pass the test
most of my camper has now got extra insulation and not the basic done by A/S and could be the cold you are getting from the rear doors as this is very poor as people see when removing the panels

On the move or parked up regards the quietness?

I don’t think the Symbol has the centre door draught strip because the seating area is not immediately inside the doors and also there’s a need to open the doors fairly frequently to empty the cassette and reach things like the table stored there. The centre strip has to be removed from inside prior to opening the doors. Tbh, it’s a bit of a pain.

We never found the single glazed windows an issue. With both Warwick Duos we pulled up the concertina blinds when the temperature dropped and all became snug and draught free. Never bothered with the faff of pulling curtains though.

Silver foil reflects radiant heat so if its on the inside of the blind it will help keep heat in and if its on the outside it will help keep heat out.  If it's on both sides it will do both.
