Frequently Asked Celotex TB4000 Questions
How Does Celotex TB4000 Improve Thermal Performance?
The board's core is designed with a thermal conductivity of 0.022 W/m.K, which minimises the amount of insulation needed to achieve desired U-values.
Moreover, the low emissivity foil facing enhances thermal performance within cavity air spaces, significantly improving U-values.
Can Celotex TB4000 Be Used in Any Building Type?
While versatile, it's important to consult relevant building regulations and standards, especially regarding fire safety and height restrictions for external walls.
Celotex TB4000 carries a Euroclass F Reaction to Fire classification, making it unsuitable for use in the external walls of buildings over a certain height.
What Certifications Does Celotex TB4000 Hold?
Celotex TB4000 is BBA certified, ensuring it has been rigorously tested and found suitable for use in defined roofing, wall, and floor applications when installed and maintained according to the certification guidelines.
