Thermal insulationThe goal with thermal insulation is generally to reduce the amount of heat that can escape from a property to improve energy efficiency. However, there are also cases when it needs to prevent fire from spreading. The aim here is to improve safety. The insulation will keep the fire within a compartment so there is more time for people to exit from other parts of the building.

There are several different materials you can use to insulate a property. We work with a number of them at Trident Fire Protection & Training. As a result we are in the perfect position to offer advice. We can look at the different types and suggest the right one for our clients.


One of the best options for thermal insulation is fibreglass. It is a non-flammable material and stops conduction heat transfer. These are both excellent if you want to prevent a fire from spreading.

Mineral wool

There are several options here, including rock wool or slag wool. Whatever type it is though, the wools are non-combustible and can also provide acoustic benefits. However, on their own the materials don’t have the best fire resistant properties. You may need to pair them with other insulation, especially if you anticipate extreme heat.

Phenolic boards

This is one of the best options if you want thermally efficient insulation with great fire performance. Each board has a top and bottom facing. Between them is a layer of wet foam that is cured in an oven. The end result is boards that are great at withstanding fire. They are useful for roof, wall and floor applications.

Other options

There are lots of other types of insulation too. This includes mica, polystyrene, polyurethane foam, cellulose, PIR and VIP panels.

It is important to take a close look at each type to see what benefits it can offer. You should also check how difficult it is to deal with and what you will need in terms of safety equipment and other materials.
