Insulation Fixings

Insulation fixings are designed to securely affix insulation boards or batts within your walls, floors, or ceilings. Whether you're insulating a new build or retrofitting an older home, proper securing ensures effective spacing and heat retention.

There are many types of insulation fixings available, most designed to drill or attach into solid surfaces like concrete and wood. These fixings have wider heads than typical screws to better anchor insulation batts. It's important to tape and seal these heads after installation, as plastering directly over them can cause surface issues. They can be used with various insulation types, including glass wool, rock wool, and mineral wool.

Using the right insulation fixings is essential for a professional finish. In both new builds and renovations, quality fixings help position and hold insulation in place within walls, ceilings, and floors. Sealing the heads after installation ensures a clean surface for plastering.

Fixings can be plastic or metal and are typically designed for solid walls, using expansion plugs that specify a required drill hole size. After drilling the hole, the fixing is inserted and hammered in—then expands to form a secure bond. Some fixings are engineered for strong grip with minimal embedment, making them suitable for hollow walls.

We also stock fixings for insulated plasterboard, including Gyproc branded plugs in 60mm and 110mm sizes, ideal for use with Gyproc Thermaline boards. These are inserted into pre-drilled holes and allow you to hang modest weights. Each type is sold in boxes of 100. It's important to use appropriate fixings when hanging anything from insulated plasterboard to ensure safety and durability.
