Customer Questions
What’s the best glue to use for sticking the boards to wood?
It is best to mechanically fix the boards. This is because the adhesive will only be as strong as the foil facing. If you want to glue aswell as mechanically fix, a general purpose adhesice such as Stixall can be used.
Why is there foil on the Celotex GA4000 boards?
Celotex GA4000 boards along with TB400 and XR4000 are foil faced on both sides. These facings have a low emissivity and help reduce heat transfer, which improves thermal performance.
What sizes are available in the GA4000 range?
The Celotex GA4000 range are in sheet sizes of 2400mm by 1200mm. The GA4000 is available in 50mm, 60mm, 70mm, 75mm. 80mm, 90mm and 100mm. Other thicknesses are available in TB4000 (thinner) & XR4000 (thicker).
