Which thermal insulation material is the best choice for you? An overview


Insulating your home with a qualitative thermal insulation material is no luxury. Not only will it improve your home’s market value, it will also enable you to save considerably on heating costs. In addition, investing in thermal insulation means you’re doing your bit to help the environment. And, not to forget, insulation standards are becoming stricter all the time. For example, the new 2020 insulation standard requires homeowners to insulate all flat and sloping roofs, whether they’re renovating or constructing a new building. But how to choose the right insulation material? Read this article to gain a handy overview of SOPREMA’s extensive range of thermal insulation materials.

XPS: a widely popular insulation material

Starting late 2020, we will be producing our entire XPS range in our brand-new factory in Tongeren, a Belgian city located in the province of Limburg. Using sophisticated CO² technology, our entire XPS production process is eco-friendly. Moreover, the material itself is 100% recyclable. XPS is particularly suitable for insulating car parks, high-traffic flooring and the entire building envelope. What’s more, this insulation material is moisture-insensitive and the boards offer excellent compressive strength.
Gemadrain comes with built-in bubble foil and is especially useful for sealing foundation walls, which tend to require thorough insulation and, in a next step, bubble foil to direct moisture downwards. In other words, Gemadrain is a two-in-one product and will therefore help you get the job done in just half the time.


Frequently referred to as ‘polystyrene foam’, EPS is an easy and safe insulation material to handle. EPS boards such as NEOSTIR 029 are an ideal choice for insulating flat roofs.


PIR and PUR are both excellent insulation materials with a very low lambda value. Despite their limited thickness, these materials are great for thermal insulation. PIR and PUR are light-weight and therefore easy to install. Moreover, both materials are fire-retardant and neither of them irritates the eyes, skin or respiratory tract.

Wood fibre

Do you prefer to use natural materials? Then PAVAFLEX is the perfect insulation material for you. Made from wood fibre (residual wood from sawmills), PAVAFLEX is incredibly eco-friendly and requires less energy to produce than any other insulation material. And there’s more: PAVAFLEX is a breathing material that can be used for acoustic insulation and acts as a fire-retardant to boot. In the event of a fire, a carbonized layer forms on the surface of the material, preventing oxygen from passing through and thus keeping the fire from spreading. Unsurprisingly, wood fibre insulation is particularly popular in combination with timber frame construction. The material is also suitable for insulating ventilated walls, combinations with crepi and even for circular construction.
