Pavatex NBT Steel Frame Pavaclad System
fibreboard insulation system for steel frame construction with cladding
'Pavatex NBT Steel Frame Pavaclad System is for light steel buildings externally finished with any type of cladding including facing bricks, rendered blockwork, timber boards or shingles, tile, terracotta claddings, metal sheet etc.
Pavaclad systems use Pavatex woodfibre boards over the outside of the frame in a continuous layer to give an unbridged thermal shell, with excellent breathability and acoustic insulation. The airtightness layer is on the inside of the frame and it is optional whether to install a service void on the inside of this layer for easy service alterations.
System benefits
• Excellent thermal performance, with very low thermal bridging, enabling very slim construction for new Part L compliance
• Alternatively very high thermal shell performance possible in slim and cost effective way
• Excellent airtightness by design
• Excellent acoustic insulation
• Good overheating control
• Fully breathing construction
• Full design and site support from Burdens Environmental
• Full systems parts from Burdens Environmental
• Tried and tested system, fully certified
