Plasterboard is a versatile material commonly used in interior walls and ceilings. When combined with insulation, as in insulated plasterboard, it offers enhanced thermal performance. This is ideal for:
Retrofitting insulation in existing homes.
New builds where space is at a premium.
Areas where you want to combine the benefits of plasterboard with insulation in one product.
Foil Insulation
Foil insulation is a radiant barrier that reflects heat, making it effective in preventing heat transfer. It's especially useful in:
Lofts and attics to reflect heat back into the home during winter and keep heat out during summer.
Walls and floors where a slim, high-performance insulation is required.
Spaces where moisture resistance is essential, as foil acts as a vapor barrier.
PIR Insulation & Insulation Board
PIR (Polyisocyanurate) insulation is a type of rigid foam board that offers excellent thermal performance. Insulation boards can be made from various materials, including PIR, and are known for their:
High thermal resistance with a relatively thin profile.
Suitability for floors, walls, and roofs.
Durability and long lifespan.
Fireproof Insulation
Safety is paramount, and fireproof insulation is designed to resist the spread of flames. This type of insulation is crucial for:
Areas with a high risk of fire, such as kitchens or near fireplaces.
Commercial buildings where fire safety regulations are stringent.
Any space where enhanced fire resistance is desired for peace of mind.
Mineral Wool
Mineral wool is made from natural or recycled materials and offers a combination of thermal and acoustic insulation. It's perfect for:
Internal and partition walls for soundproofing.
Lofts and attics for thermal insulation.
Spaces where a breathable insulation material is preferred.
