Warm Deck Insulation Fixing for Steel Deck (Box 100)

This warm roof deck insulation fixing is designed to secure insulation to a steel deck between 0.7-1.2mm. 

Important: You will receive a tube washer & screw combination designed for your roof thickness. The roof thickness is the insulation thickness + the upper deck thickness (if applicable). For example if you have 150mm insulation and an upper deck of 18mm timber then the roof thickness is 168mm so you would select 170mm (190mm overall length). If you had 150mm insulation with no upper deck then you would select 150mm (170mm overall length.) If you are unsure please contact us and we will be happy to advise the size you require. 

This innovative fixing combines an insulation tube washer and screw to fix the insulation to the steel substrate. They are designed to secure through the lower deck and protrude by approximately 20mm to create a secure fix. They are not intended for fixing into the roof joists below.  

What size insulation fixing do you need?

The fixing size selected is the depth of the materials from the lower deck upwards. So this is the Insulation Thickness + Upper Deck thickness (such as 18mm timber overlay). 

A steel fixings allow for a 0.7 - 1.2mm deck. The screw will then protrude the lower edge of the deck by 20mm. The following diagram shows most standard roof build-ups.
