Celotex Wall Insulation

Our Celotex wall insulation sheets comply perfectly with the thermal requirements of building regulations and can meet the demands of all builders. Celotex is the UK’s top brand for providing insulation materials for building and construction so we are proud to offer you their high-quality wall insulation boards for a great value price. We have a large range of Celotex wall insulation boards available, with thicknesses ranging from 25mm to 200mm, most of which will cover an area of 2.88m² per board. 

Which type of Celotex wall insulation you should choose depends on your particular needs. If your main motivation is reduced energy bills, our PIR boards are the best option for you. To overcome cold spots in a building, you should take a look at our multi-purpose insulation boards. Our insulated plasterboard will allow you to undertake two steps at once by combining insulation boards and plasterboard for installation at the same time so if your project is short on time, this may be the right option for you.

In addition to improving the thermal qualities of the building to reduce heat loss and heat gain, Celotex wall insulation boards will also reduce noise, which is particularly important in flats and terraced properties. Recommended products include Celotex Solid Wall Thermal PIR Insulation, External and Internal Wall Insulation Boards, and Celotex High-Performance Wall Insulation.
