Covering 5 square meters per roll, it’s easy to install and creates a smooth surface ideal for wallpaper or emulsion, making it the savvy choice for efficient, space-saving thermal insulation. ## 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!!

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product. Easy to put up & great thermal properties *by T***E on 26 March 2014* Bought this after reading other good reviews.

Excellent product & brilliant result!! ### ⭐⭐⭐⭐⭐ Quality Product *by S***R on 13 April 2026* Very happy with my purchase ### ⭐⭐⭐⭐ Its Good but BEWARE... *by M***C on 10 January 2014* I'm a novice when it comes to DIY but I had set my mind to it and gave it a go. Although the roll is somewhat delicate and brittle, I still found it very easy to hang and any cracks and damage I made to it in the process were easily fixed. It covered up an uneven, pitted wall perfectly and with some filler in any gaps or breakages, it looked very much like my amateur skills had pulled off a professional job and I was very proud. I now had a new smooth and insulated wall! Step 2 was to apply lining paper so I could paint it. I left the polystyrene and filler to dry for 24 hours and then I went to work with some plain budget lining paper. With my confidence boosted, adding a degree of patience and care, I was able to do a fairly good job of this too. At the end it looked like I had finally revamped an otherwise ugly interior wall... I left it all to dry for another 24 hours... ...Unfortunately, it seems the so called "super strong" wallpaper adhesive I had decided to purchase having spied it in the the "frequently purchased together" section wasn't quite so strong as it claimed. My almost perfect job fell off the wall within hours of drying!! I had to attempt a frustrating rescue (all those pain staking hours wasted!)Having purchased some decent adhesive I tried to stick the paper back on. Of course by this point it was never going to look as good. Really I needed to rip the whole lot off and start again. I may still do so if I fail to remove the bubbling and creases I've been left with... MAKE SURE YOU BUY AN APPROPRIATE ADHESIVE and you'll have a good result! ## Frequently Bought Together - Erfurt Mav Polystyrene Wall Insulation - 2mm x 50cm x 10m - Insulated Underlay for Llining Paper - Wallrock Dampstop Thermic Adhesive 1kg --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/49179054-polystyrene-wall-insulation-2mm-x-50cm-x-10m-insulated-underlay](https://www.desertcart.jp/products/49179054-polystyrene-wall-insulation-2mm-x-50cm-x-10m-insulated-underlay) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-09*
