Celotex Insulation

Celotex provides a range of safe, reliable and high-quality insulation materials that are used to insulate countless homes and buildings all over the UK. Thousands of professionals choose Celotex to create environments that save energy every day. Insulation can help buildings reduce heat loss, which minimises the need for heating the building and therefore has less strain on the planet. In addition to this, Celotex manufactures its products with zero Ozone Depletion Potential. This is because they are environmentally conscious and provide innovative ways to help prevent global warming.

Builders love using Celotex as it is easy to install and cheap without sacrificing performance. Celotex saw its first big boost in popularity after WW2 when building materials were scarce. Since then, the products have improved and the brand has grown into the powerhouse that it is today. There are not many (if any) builders or property developers who have not heard of Celotex.

Most Celotex Insulation products are easy to cut to suit the application. In addition to this, Celotex installation is simple and can be achieved in multiple ways. The method of installation depends on the product or application. Please see our How to guides for a step by step guide on how to install.
