Builders are likely to see demand for insulation increase as the weather gets colder this season, so it is important to know what the different types of insulation are so they can offer their customers the best building supplies.


Loft insulation

Insulation used for the loft is typically dense and rigid. It comes in different thickness depending on what the homeowner requires. Different sizes ensure it will be able to fit the loft as much as possible, leaving few gaps for air to travel through. 


Cavity wall insulation

This form of insulation can be injected into cavity walls from the outside before being sealed with cement. 

The material is typically mineral wool, polystyrene beads or polyurethane foam. To fit cavity wall insulation, a specialist is required as they need to drill small holes throughout the outside wall and need special equipment to fit the insulation.

Most houses built from the 1990s onwards will have cavity wall insulation, while houses built before the 1920s are unlikely to have cavity walls that you can insulate at all.  


Jablite insulation

Jablite is becoming increasingly popular, as it can be used for a variety of purposes. These include insulating the roofs, walls, floors and basements of a property. 

The good news with this type of insulation is they come in single boards that are easy to cut down to the right size. What’s more, customers can choose the thickness they want. 


PIR board insulation

The PIR in PIR board insulation stands for polyisocyanurate. The reason why this is growing in popularity is because it can be used in insulated metal panels and wall cavities. It can also be used as insulated plasterboard. 

What’s more, it can be cut into boards and is half as thick as alternative mineral-based products.
