Wärmer System Underfloor Heating Aluminium Superfoil is underfloor heating insulation designed to boost heat retention while accepting screed directly. Homeowners fitting new floors or upgrading heating systems can expect warmer, more consistent floors and reduced energy waste. Is the performance and durability right for your installation?
⚡ At a Glance
- • Thermal Efficiency: Reflective aluminium surface redirects radiant heat, helping retain warmth beneath flooring
- • Best for: Installers and homeowners fitting underfloor heating beneath laminate, wood, carpet or tiles
- • Not ideal for: Projects requiring a structural underlay or insulation with rigid support properties
Reflective aluminium foil supplied in 1m x 50m rolls enhances underfloor heating efficiency and accepts screed directly. Acts as a moisture barrier and suits laminate, wood flooring, carpet and tiled finishes.
Even heat distribution - with reflective aluminium surface
Aluminium foil reflects radiant heat back towards the room surface rather than allowing it to escape downwards, increasing the proportion of usable warmth. The surface is designed to be compatible with direct screed installation.
More consistent floor temperatures across rooms, reducing cold spots and helping the heating system reach set temperatures faster.
Protection from damp - thanks to built-in moisture barrier
A continuous foil layer prevents moisture and condensation from penetrating into the heating layer and subfloor, acting as a physical barrier. The material resists water ingress where installed correctly.
Reduced risk of damp-related issues for underfloor heating elements and subfloor materials, offering greater peace of mind in ground-floor installations.
Quicker installation on large areas - with 1m x 50m rolls
Long, lightweight rolls are simple to unroll and cut, minimising joins and handling time. Flexibility allows fitting around pipes, ducts and irregular shapes without specialised tools.
Faster on-site fitting and fewer seams means less time in preparation and a cleaner finish around services and edges.
