Warm Deck Insulation Fixing for 18mm Timber Deck (Box 100)

This warm roof deck insulation fixing is designed to securely fasten insulation to an 18mm plywood, timber or OSB deck, ensuring a reliable and long-lasting installation. 

If your timber deck is less than 18mm please contact us for advice as you will require a different size tube and screw combination. 

Please Note: These fixings are not intended for securing into roof joists. They are designed to protrude approximately 20mm through the lower deck, as tested and recommended by manufacturers. 

Important: Your tube and screw combination will be selected based on the information you provide. Please ensure you choose the correct options for your roof to receive the appropriate fixings. All combinations are manufacturer-recommended. 

How do these fixings work?

This innovative design combines a high-quality fixing with an insulation tube washer to securely fasten insulation to an 18mm timber substrate. The tube passes through the upper deck (if applicable), into the insulation, while the screw starts near the bottom of the tube and extends through the remaining insulation and timber, protruding through the timber deck by approximately 20mm to ensure a secure fix.

Features of these fixings:

• Thermal Break: The screw head starts near the bottom of the tube washer, reducing thermal bridging.
• Telescopic Design: Allows for natural roof movement without puncturing waterproofing layer above.

How many fixings do I need for my insulation?

• 2400mm x 1200mm - 12 fixings per board (If your project is exposed or is in a high wind area this should be increased to 16)
• 2400mm x 600mm Tongue & Groove Board - 8 fixings per board
• 1200mm x 1200mm board - 9 fixings per board.

Do I need to fix through into the joists or firrings?

• No, the lower deck should already be fixed to the joists and/or firrings so the insulation only needs to be secured to the lower deck.
• These fixing are designed to protrude through the lower deck to allow for a telescopic feature. Securing into the joists doesn't allow for this movement.

Which P2 Bit do I need?

• 50 - 70mm Roof Thickness - 50mm P2 Bit
• 80 - 110mm  Roof Thickness - 110mm P2 Bit
• 120 - 160mm  Roof Thickness - 150mm P2 Bit
• 170mm + Roof Thickness - 200mm P2 Bit
