Wallrock Thermal Liner
I won’t give all of the technical detail here. Click this link to read more about Wallrock Thermal Liners on the Cover Your Wall website.
Before we look into how Wallrock Thermal Liner is built and how it works, some key facts from the manufacturer:
- it reduces room warm up time by up to 65% and can offer up to 36% energy saving
- provides noise insulation: aw=0.02
- helps with fighting the mould
Read and see below and you’ll realise that apart from the thermal benefits, Wallrock Thermal Liner will cover some pretty rough walls – it’s 3.2 mm thick. I’ve always wondered how some retailers can make claims about their thin wallcoverings (0.5 mm) being able to cover things like woodchip!! Do they really think we are…not very clever?
Has it been tested? British Board of Agrement (BBA) tested Wallrock Thermal Liner and decided it saved 15% of the static heat loss. However, we fed the same raw data numbers to one of our customers who works with ‘these things’ and he reckons it’s 20%, but we’ll stick to the official figures. In order to get a rough idea of the potential savings, please use this Wallrock Thermal Liner Saver Calculator to get a rough idea.
How thick is it? 3.2 mm thick. Below you can see an image where I used a pencil to show how thick the Thermal Liner is. As it’s not stuck to the surface, it bends upwards in the middle though. Yes, it’s flexible (it comes on a roll); however, when tackling sharp corners I’d suggest you cut it and not bend it or you’ll end up with slightly round corners.
What is it made of? Below is a side image of Wallrock Thermal Liner. On the left you have a flat and paintable surface (a layer of Wallrock Fibreliner), which is backed by the thermal layer. In simple terms, the thermal layer reflects the heat back into the room / doesn’t allow it to sink into the wall as fast thus allowing your room to heat much faster and stay warmer. No, it’s not the same as outside (or in-wall) insulation and nobody is claiming it’d do the same job, but the costs are vastly different. The product came about when some white-coat lab guys looked into technologies used by NASA and the car industry.
What about the finish? The image below shows a sample of unpainted Wallrock Thermal Liner against a painted wall (there’s no Thermal Liner on this wall though). This image has been magnified, so please take this into consideration.
So, Wallrock Thermal Liner is on the wall. What next? Paint it – job done! But you can do more, if you want to.
You can overline it with Wallrock Fibreliner, Wallrock Premium or Wallrock Trend paintable wallpapers (depending on the finish you’d like to achieve). No, you shouldn’t be using traditional lining paper or wallpaper – more about it on coveryourwall.co.uk, but we’ll be talking about this here soon. Below is an image of where the two lengths of Wallrock Thermal Liner meet on an uneven wall. Because it’s 3.2 mm thick it can create a slight level difference where the two lengths meet – in this case the wall is in a very old cottage. For some it’s not a problem at all whilst others would like to avoid it. This is the reason why we suggest you can overlay it with one of the above products and cover any of the problematic areas.
