## Description

Heatsaver is an economical, 2mm thick polystyrene liner containing fire retardants that provide basic insulation as well as combatting condensation and mould growth. To create a more durable and smoother surface we recommend the product is overlined - Wallrock is particularly tough and strong. Recommended adhesive; Good quality ready mixed adhesive suitable for polystyrene veneer..Coverage 5.0m .Roll length 10m single .Roll width 0.5m

Review: Great product. Easy to put up & great thermal properties - Bought this after reading other good reviews. Have used it on external walls and the heat retaining effect is excellent, as well as giving a smooth flat surface for further lining paper & emulsion. Provided you are thorough with your decorating preparation, and use correct wallpaper paste to water ratio (I used ratio for blown vinyls), this product adheres to the wall well & doesn't peel away. Another tip: forget the how-to-hang diagram & apply across the wall rather than top to bottom. Start at the skirting level; after pasting the wall, take the whole roll (don't pre-cut the length) & apply the Poly' Lining paper to the wall working from left-to-right (if left handed work right to left) & cut to size. Repeat the process until the whole wall is lined. When you later apply a paper lining paper, hang that as normal (ceiling to skirting) & emulsion. Good preparation before using the product is the main thing. I also pasted the walls with Glue-past and allowed to dry prior to pasting the wall and putting the Poly Lining paper up. Excellent product & brilliant result!!
Review: Happy - This would've got 5 stars but slightly damaged on arrival. Got this to help with wall that gets slightly mouldy. Good to work with and so easy to apply. Very happy with end result, so warm to touch. Hoping problem resolved re mould

## Questions & Answers

**Q: Can I use it on a cage for my guinea pigs on the outside of course for the winter**
A: You ask can you use it to cage your Guine pigs outside this winter,I would use it in between water poof lining,but be on the safe side ask you local pet shop.all the best

**Q: will it cover woodchip**
A: I would recommend rubbing the woodchip over with sand paper, just to knock off any high or loose chips. Ensure the paper is well glued. Use a thick solution of wallpaper paste and apply to the surface. Then roll across the wall the poly, paper. Should cover OK  then apply your finishing cover.
But alway best if woodchip is removed..

**Q: Is it strong or will it rip easy?**
A: The one I had went on well but once it's wet with paste it does tear easily when you're smoothing it out etc. Although I think there are different thicknesses you can buy.It's also better to cut/trim with scissors instead of a Stanley knife as the blade can sometimes drag instead of cut which then tears the polystyrene.Hope this helps.

**Q: Can you paint on to this without covering with lining paper first**
A: It is not smooth but has lots of tiny spaces between the polystyrene beads so painting over will leave the gaps unpainted unless you give it many coats to fill them. Best to put lining paper over the top with a suitable adhesive before painting.  You can now buy an insulated lining paper which is much more expensive but ready to paint and saves time and more durable as the 2mm insulation on its own is very easily damaged and crumbly.

### ⭐⭐⭐⭐⭐ Instantly transforms a cold exterior wall.
*by R***E on 13 September 2016*

I love this item. It comes very well packaged, does exactly what it says on the sales pitch, and is very cheap. I must say it was a testing time applying this to the walls as it is very thin, however, take your time and you will get used to this. Once applied it is a very good, effective, insulating material, you can feel the difference straight away just by touching the walls. Rather than a freezing cold wall (i live in an old thick walled building) the walls are actually warm! I would recommend this to anyone who has condensation damp issues as i am sure it is going to help with that over the winter months. Make sure you use the correct adhesive and you can't go wrong. I have also wallpapered over this with anaglipta paper and will be painting over the top of that as well.
