Granol
The Granol range of systems have been rigorously tested to German standards. Germany is the largest market for external wall insulation with approximately 30 million square meters being installed annually. Therefore the range of testing facilities in Germany are far greater than that found in the UK. The Granol range of systems has been assessed by the German Institute of Construction Engineering and has been approved as meeting all the requirements of the German Regional Building Regulations The individual component parts to the systems have also been independently tested to the Relevant DIN Standard.
Insulation
Mineral wool insulation have been manufactured in accordance with DIN 18 165-1.
Polystyrene insulation have been manufactured in accordance with DIN 18 164-1.
Moisture Penetration
The system meets all the requirements of the german building inspectorate in accordance with DIN 4108-3. The use of external wall insulations is much more widely used in continental Europe than it is in the UK and therefore the German testing regime and the requirements of the German building regulations are much more stringent than in the UK. Despite this some quarters of the UK construction industry request British Board of Agreement Approval. Therefore the Granol systems have undergone a complete and successful assessment by the BBA (No 05/4206). Copies of the agreement certificate can be obtained by contacting our offices.
