PIR Boards for Between and Under Joists - Cold Roof

This category contains all PIR insulation boards suitable for between and under joists applications in cold roof construction. Boards are manufactured by top UK brands like Kingspan, Celotex, Recticell and Xtratherm all available in our online shop. Cold roof structure is characterised with a ventilation air gap situated above insulation to prevent moisture condensation and allowing the roof to 'breathe'. The air gap should be at least 50mm high to allow sufficient ventilation. All of our cold roof insulation boards are available with 1-2 working days delivery across UK.
