Plywood Fixings FAQs

What size insulation fixing do you need?

The fixing size is the depth of the materials from the lower deck upwards.

A timber deck fixing allows for an 18mm lower deck, any less than 18mm please contact us as you will need a different product size. The screw will then protrude from the lower edge of the deck by 20mm. The following diagram shows most standard roof build-ups.

How many fixings do I need for my insulation?

• For a 2400mm x 1200mm board, we recommend 12 fixings per board. If your project is exposed or is in a high wind area this should be increased to 16.
• For a 2400mm x 600mm T+G board, we recommend 8 fixings per board.
• For a 1200mm x 1200mm board, we recommend 9 fixings per board.

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

No, the lower deck should be fixed to the joists and/or firings. The insulation only needs to be secured to the lower deck.
