Between & under joists

Use a combination of Celotex TB4000, Celotex GA4000 and XR4000 high performance thermal insulation in flat roof between and under joist applications to minimise insulation thickness and give the following benefits:

• A perfect solution to upgrade older buildings 
• Provides reliable long term energy savings for buildings 
• No need to remove existing weatherproofing covering 
• Ventilated cold roof construction 
• The ideal renovation/conversion solution 
• Easy to minimise any loss of internal headroom

Alternatively, using TB4000 or GA4000 with PL4000 plasterboard thermal laminate provides both the insulation and plasterboard in one product, helping to reduce installation time.
