Integral Vapor Control Layer

The composite glass tissue facing on SR/TB acts as an impermeable barrier to gas and moisture, significantly minimising condensation risk. When joints are sealed and taped following standard drylining practice, the board creates a continuous vapor control layer across your wall surface.

Fire Stops

When installing drylining, fire stops must be positioned at the top and bottom of each board, plus around all openings including doors and windows. These consist of continuous lines of adhesive that prevent fire spreading behind the insulation. The unbroken adhesive also eliminates thermal bridging, improving the overall U-Value performance of your wall assembly.

Handling, Cutting, and Storage

Store Unilin PIR insulation boards on a clean, level surface above ground, protected from weather and rain. Polythene wrapping alone won't shield the product from outdoor conditions. Take care during storage and throughout your build to keep the insulation in good condition. Always wear appropriate personal protective equipment (PPE) when handling insulation materials.
