Rock Wool:
Made from volcanic rock, it offers excellent fire resistance and sound insulation along with thermal insulation.
Sheep’s Wool
Natural and sustainable, sheep’s wool is highly effective at regulating temperature and humidity. It is also biodegradable and has good soundproofing qualities.
Rigid Foam Boards (PIR boards)
PIR (Polyisocyanurate) and PUR (Polyurethane):
These boards offer high insulation value and are moisture-resistant, making them suitable for loft spaces.
XPS (Extruded Polystyrene) and EPS (Expanded Polystyrene):
These are lightweight and offer good insulation properties, though they are less effective than PIR and PUR.
Multifoil Insulation
Multifoil consists of multiple layers of reflective foil and insulating materials. It is thin, lightweight, and reflects radiant heat, making it a good option for additional insulation or in spaces with limited headroom.
Natural Fibre Insulation (Hemp, Cotton, Wood Fibre)
These materials are sustainable and environmentally friendly. They provide good thermal and acoustic insulation and are often treated to be fire-resistant and prevent pests.
