Description

PIR insulation board termPIR® AL GK-OSB, is an advanced solution that significantly increases the energy efficiency and durability of building structures. The boards consist of a core made of rigid PIR foam, which provides excellent thermal insulation properties. They are covered on both sides with a gas-tight sandwich lining of paper and aluminium, which further protects against heat loss. An 8-22 mm thick OSB board reinforces the entire structure and a 12.5 mm thick GK board provides additional strength and is ideal for interior finishes. There is an adhesive layer between the aluminium cladding and the OSB and GK boards, which guarantees a durable and robust bond between all components. termPIR® AL GK-OSB is the ideal solution for projects where both effective insulation and structural soundness are important.
