JIF Fasteners

Insulation fixings, otherwise known as insulation anchors, are fixings which are used to keep external wall insulation and over-rafter warm roofing systems in place. Insulation fixings are typically made from metal, such as steel, or plastic, with a long nail-like fastener which penetrates the background material and a large, circular head to pin the insulation down onto the structure.

Insulation fixings can be used on many different types of insulation and substrates. This includes mineral wool, foam, XPS and EPS. Insulation fixings moreover work on composite insulation boards.

Insulation fixings should be designed to meet the requirements of the material and substrate, this may include a larger washer or head diameter to hold thinner materials. 

Metal fixings, especially A1 fire rated products, maintain the integrity of insulation systems during the event of a fire. Insulation boards can act as a passive fire protection system, therefore to help prevent or slow the spread of fire, it is important that these boards remain in place.

Plastic fixings do not have the same temperature resistance as metal fixings in order to achieve this.
