2 x Erfurt Heatsaver Wall Underliner Wall Insulation Polystyrene Lining 2mmx10M

The Erfurt Heatsaver Wall Underliner is a 2mm thick polystyrene liner designed to provide basic insulation and combat condensation problems on interior walls. It's an economical solution to help keep your home warmer and reduce the risk of mold growth. The underliner is also fire retardant and CFC-free.

Perfect for the job never used this product before easy to apply.

I've used this before for a ceiling which had a dew point causing condensation and then a mould problem. The most recent application was in my storage room where it is lacking any heat and during winter months used to almost cascade with condensation.Seems to have mitigated and the room is not as cold now. Just waiting for the freezing -5° temps to return to see if there are any more dew points hopefully there won't.

I live in an old house no cavity wall insulation so I’ve used this s lot and I’m convinced it helps.Goes on easily if you paste the wall, it tears easy so you have to very careful but worth the end result, you need to paper over it I used lining paper and then emulsioned

This stuff is very flimsy. Rips and tears very easily. don't purchase if not confident in your own ability. Saying that does what it is says

Easy to use good quality value for money

I've had a couple of problems with it ripping as I was putting it on but I'm not worried because it is in an area where it can't be seen

A plasterer recommended this to us when we had an issue with damp and condensation in our new house with it being an end terrace. We had two built in wardrobes with this problem so I lined them with this using normal paste very thick and it’s helped massively.
