25mm Multi Purpose PIR Insulation Board 2400 x 1200mm

Multi-Purpose PIR Insulation Board supplied in sheets 2400 x 1200 x 25mm - Less expensive option than Kingspan with all the same benefits.

PIR insulation, or polyisocyanurate insulation, is a type of rigid foam insulation that is used in many different types of buildings across the construction industry. It is a closed-cell foam, which means that the gas bubbles that make up the insulation are completely sealed off from each other. This makes an insulation board that is very effective at resisting moisture and air infiltration.

PIR insulation boards have a very high thermal resistance, which means that it is very good at preventing heat transfer. It is also a very lightweight material, making it easy to install and transport. It can be used to insulate a wide range of building elements, including roofs, walls, floors, and ceilings.

25mm general purpose PIR insulation is a popular choice for both residential and commercial construction. It is particularly well-suited for use in energy-efficient buildings, as it can help to reduce energy consumption and costs. 

Product Uses for 25mm Multi-Purpose PIR:

As you would expect from a multi-purpose product, these 25mm sheets can be used for many applications. The most common uses are:

• Flat and pitched roofs both warm and cold

• To fill the voids between timber joist floors

• Above or below a concrete floor slab

• To insulate the voids in a metal or timber wall lining system

Depending on location, the 25mm board sent could be either Celotex, Ecotherm, Unilin (formerly known as Xtratherm), Recticel, Mannock (formerly known as Quinntherm) or IKO Enertherm. All of these have the same thermal performance properties as the more expensive Kingspan branded boards. They also have the same compressive strength of 140 kPa.

Here are some of the benefits of using 25mm PIR insulation:

• High thermal resistance: PIR insulation has a very high thermal resistance, which means that it is very good at preventing heat transfer. This can help to reduce energy consumption and costs.

• Water-resistant: 25mm multi-purpose PIR insulation is a closed-cell foam, which means that it is very water-resistant. This makes it a good choice for use in areas where moisture is a concern.

• Environmentally friendly: Multi-purpose PIR insulation is made from recycled materials, and it can be recycled at the end of its life cycle.
