    Frequently Asked Questions – Insulation

    What type of insulation is best for lofts?
    Mineral wool rolls are commonly used in loft spaces due to their ease of installation and excellent thermal performance. They are typically laid in two layers to meet recommended depth.

    What is PIR board used for?
    PIR insulation boards offer high thermal resistance and are ideal for floors, walls, and pitched roofs. They’re lightweight, rigid, and often faced with foil for enhanced performance.

    Do your insulation products meet UK regulations?
    Yes — all our insulation products are compliant with UK building regulations and can help meet U-value targets for thermal efficiency under Part L.

    Can insulation help reduce noise between rooms?
    Yes — acoustic mineral wool and sound insulation slabs are designed to reduce airborne sound transmission in internal walls, floors, and partitions.

    Do you offer bulk or trade pricing for insulation?
    Yes — we supply full packs and bulk loads for trade and commercial jobs. Contact us for quotes, delivery options, and availability on large orders.
