Frequently Asked Insulation Screws & Fixings Questions

Frequently Asked Questions About Insulations Fixings

What Insulation Board Fixings Should I Use To Install Fire Resistant Insulation? 

We recommend opting for a non-combustible mechanical fixing such as zinc-plated carbon-steel and stainless-steel fittings. 

Metal fixes are classed as A1 on the Euroclass scale, deeming them non-combustible and in line with the requirements of BS EN 13501.

Why Should I Use Washers When Fastening Insulation? 

The hole in the middle of washers is designed to accommodate screws or bolts. This helps to keep the screw secure and prevent it from loosening. 

It also aids in distributing the load from the nut or bolt head across a wider area, preventing damage to the fasteners themselves.
