Welcome to Therma-Foil – the revolutionary foil insulation that offers high performance as loft, wall, and floor insulation. Therma foil insulation products are reflective to heat back towards the source up to 97 %. Designed to maximise your building’s heat efficiency, Therma-Foil is an infra-red reflective foil that’s bonded with a layer of closed-cell foam, creating an easy-to-install and flexible product that’s ideally suited for a wide range of applications in domestic, commercial and educational premises.


Whether you looking to insulate your roof, floor or walls, Therma-Foil will be great choice for you. Therma-foil acts as both a vapour barrier and a reflector of infra-red radiation, this helps with keeping heat in your home during the winter and protecting it from overheating in the hot summer months. Created to save energy all year round, Therma-Foil is one of the most effective ways to cut your heating bills and and with Therma-Foil installed you will surly notice a difference.

Installation is very simple, with none of the hazards of traditional fibre-glass insulation. Made from 100% recyclable materials, Therma-Foil insulation is fibre-free, non-asthmatic and non-itchy… Subsequently you won’t need to wear protective clothing when fitting it. Furthermore, this means you can install Therma-Foil in environments where allergens and irritants may have previously been a factor, including hospitals, schools and homes. Our foil insulation will also help you to meet the latest European air-tightness guidelines and can be installed along with secondary insulation to achieve even the strictest standards.

With radiant heat transfer reduced by up to 97%, it’s easy to see how much energy you could be saving with Therma-Foil as your insulation of choice. A moisture barrier is also created that will help in protecting your floor as well as prevent heat loss into the subfloor. When used as floor insulation, Therma-Foil doesn’t lose effectiveness when compacted, giving it a long life of consistent performance even under extremely heavy foot traffic.
