Polyurethane Foam

Insulation

PIR Board

Insulation

It has a high R-value and helps increase a building’s airtightness and waterproofing because it provides seamless insulation

It doesn’t absorb either water, moisture or promote mould and mildew development, it can also protect other building materials from mould, mildew and water damage by creating a 100% waterproof barrier.

A lot of other insulation materials like wool and cellulose tend to sag over time, which can cause thermal bridges in area where there is no longer enough insulation, causing the building to be prone to heat loss. Polyurethane foam insulation is known for its excellent stability because it does not decrease in volume no matter what conditions it is exposed to.

PIR Insulation board (polyisocyanurate)

Is one of the most thermally efficient, versatile and easy to access insulation material and compared to other insulation materials in the market, it has one of the highest R-values per thickness. It has excellent thermal performance and it can easily help surpass or meet the the thermal performance standards outlined in the UK building rules and codes because it only needs half the thickness of typical mineral based insulation to obtain the same thermal performance.

PIR rigid insulation boards have a good moisture control, as it does not absorb moisture and it retains its insulation properties and weight. It’s water absorption rate is at 2% which means that the building will not have any moisture related issues or consequences. Things such as mosses, fungi, algae and lichens of any kind will not be a problem

It can perform consistently for many years, save money in energy bills and reduce carbon emissions because it can be recycled.
