The Celotex TB4025 is a premium rigid polyisocyanurate (PIR) insulation board engineered for builders, contractors and site managers who demand dependable thermal performance. Its compact 25mm thickness makes it ideal for tackling thermal bridging in floors, walls and roofs without compromising on space. Please note, this product is supplied as insulation boards only.
