Ideal for localized cold spots, it offers an easy-to-install, cost-effective solution that reduces heating expenses and enhances home comfort, though it requires additional fireproofing for full regulatory compliance. ## Description Heatsaver is an economical 2mm thick polystyrene liner containing fire retardants that provide basic insulation as well as combating condensation problems and subsequent mould growth for a healthier home. To create a more durable and smoother surface we recommend the surface is overlined - Wallrock fibreliner is particularly tough and strong.This product is suitable as a localised ‘problem solver’ for cold external walls and is not recommended for use in fire escape routes inside your home unless the surface is further treated with a fire retardant covering. This product is class E fire rated and should not be used for projects such as new builds and extensions where Building regulations are applicable.Important Safety InformationCompliance with Building Regulations; This product should not be used in isolation for projects such as new builds and extensions where Building Regulations are applicable. If used as part of a system that both adds to the insulation value and protects the surface from fire it may be compliant but expert advice should be sought.Fire Safety; When used in isolation this product is suitable as a localised ‘problem solver’ for cold external walls and is not recommended for use in fire escape routes or on ceilings.Fire resistance can also be improved significantly by cross lining the surface with Wallrock Fireliner applied with Wallrock Fireliner FR Adhesive.Preparation; Surfaces painted prior to 1960 may contain lead pigments and special precautions should be taken when preparing such surfaces. ## Features - 2mm Polystyrene Underliner - Quick and easy heat-saving on inside walls - Resists damp and mold formation - Reduces heating costs! - Roll Size: Standard Roll - 10m x 52cm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B006UFLBIO | | ASIN | B006UFLBIO | | Brand Name | Erfurt MAV | | Coverage | 5 square meters | | Date First Available | 13 August 2013 | | Global Trade Identification Number | 05060075553837 | | Is Discontinued By Manufacturer | No | | Item Dimensions L x W | 10L x 0.5W Meters | | Item Thickness | 2 Millimeters | | Item model number | CLIMA | | Manufacturer | Mav-Erfurt | | Manufacturer | Mav-Erfurt | | Manufacturer Part Number | CLIMA | | Material Type | Polystyrene | | Model Number | CLIMA | | Product Dimensions | 1000 x 50 x 0.1 cm; 160 g | | Recommended Uses For Product | wall | | UPC | 798256126970 | ## Product Details - **Brand:** Erfurt MAV - **Item thickness:** 2 Millimeters - **Material:** Polystyrene - **Product dimensions:** 10L x 0.5W Meters - **Recommended uses for product:** wall ## Images ![Polystyrene Wall Insulation - 2mm x 50cm x 10m - Insulated Underlay for Llining Paper - Image 1](https://m.media-amazon.com/images/I/51lwJkvPclL.jpg) ![Polystyrene Wall Insulation - 2mm x 50cm x 10m - Insulated Underlay for Llining Paper - Image 2](https://m.media-amazon.com/images/I/41QfO-h-cjL.jpg) ![Polystyrene Wall Insulation - 2mm x 50cm x 10m - Insulated Underlay for Llining Paper - Image 3](https://m.media-amazon.com/images/I/518L1dCfnhL.jpg) ## 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.is/products/449940164-polystyrene-wall-insulation-2mm-x-50cm-x-10m-insulated-underlay](https://www.desertcart.is/products/449940164-polystyrene-wall-insulation-2mm-x-50cm-x-10m-insulated-underlay) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-07-20*
