Frequently Asked Questions (FAQ's)
What makes PIR insulated plasterboard different? PIR insulated plasterboard combines the thermal insulation benefits of PIR foam with the practical surface of plasterboard. This combination provides superior insulation properties compared to other materials, making it highly efficient for thermal management in buildings.
Why choose PIR insulated plasterboard for your project? PIR insulated plasterboard is particularly valued for its high insulation efficiency, which can significantly reduce heating and cooling costs. It's also lightweight and easy to install, offering a two-in-one solution that speeds up construction projects and reduces overall labour costs.
Can PIR insulated plasterboard be used in all areas of a building? Yes, PIR insulated plasterboard is versatile enough to be used in various parts of a building, including walls, ceilings, and roof linings. Its robust thermal properties make it an excellent choice for both new builds and renovations where improved energy efficiency is desired.
How does PIR insulated plasterboard contribute to building sustainability? By enhancing the thermal envelope of a building, PIR insulated plasterboard helps to lower energy consumption for heating and cooling, which in turn reduces the building's carbon footprint. Additionally, some PIR boards are manufactured with eco-friendly processes and materials, further supporting sustainable construction practices.
What should be considered when installing PIR insulated plasterboard? When installing PIR insulated plasterboard, it is crucial to ensure that the boards are correctly aligned and tightly fitted to avoid thermal bridging and gaps that could compromise insulation effectiveness. Proper handling and installation are essential to maximize the benefits of the PIR insulation.
