Cavity walls: Celotex Thermaclass is an optimal choice for cavity wall insulation due to its exceptional thermal efficiency, which reduces heat loss and energy consumption, especially in colder climates. Its high-performance PIR insulation not only ensures superior thermal performance but also allows for thinner wall constructions, ideal for space-constrained projects. Additionally, its durability and moisture resistance make it suitable for long-term protection against moisture ingress, preventing structural issues and mould growth. Its lightweight design further facilitates easy handling and installation, potentially reducing labour costs and construction time. Overall, Celotex Thermaclass offers a comprehensive solution for cavity wall insulation, providing both immediate energy savings and long-term durability for building owners and occupants.

• Can Celotex Thermaclass insulation be used in retrofitting projects? - Yes, Celotex Thermaclass insulation is suitable for retrofitting existing buildings as well as new construction projects. Its specific design for timber frame constructions makes it an effective solution for improving energy efficiency and thermal comfort in both scenarios.
• What are the thermal properties of Celotex Thermaclass insulation? - Celotex Thermaclass insulation offers excellent thermal insulation properties, with a low thermal conductivity. It helps to create a more comfortable indoor environment by reducing heat transfer through the walls.
• Is Celotex Thermaclass insulation environmentally friendly? - Celotex Thermaclass insulation contains blowing agents with a high global warming potential (GWP). While it provides excellent thermal performance, its environmental impact is a consideration. Celotex offers guidance on the responsible use and disposal of its products.
