Key Features: 

Celotex GA4000 is a general-purpose insulation board designed for application on floors, walls, and roofs allowing for a wide range of  thermal insulation solutions. These boards are ideal for flat as well as pitched roofs, concrete slab ground floors, and external wall linings and sheathings. This Celotex PIR board has a low emissivity foil face to improve thermal performance and optimise space in construction especially when designing and building cavity spaces. These Celotex insulation boards are known for achieving U-values with minimal thickness.

Effective in reducing heating and cooling costs, these boards have also been ranked high amongst some of the best green insulation options for contributing absolutely zero ozone depletion potential (ODP) and for a low global warming potential. Both the blowing agent mix and the solid polyisocyanurate (PIR) used to manufacture this Celotex product, amongst many others, are environmentally friendly. 

Showcasing high tensile strength, these boards last for years with least maintenance. Celotex GA4000 insulation boards do not catch fire easily and have a class 1 fire rating. They do not break easily and are apt for tough usage in spite of their lightweight and flexible character. These are quick to install and provide flexibility thanks to the tapered edge plasterboard.
