Alumasc’s fully warranted Mastergold warm roof system was chosen for the Gelliswick Church in Wales VC School to provide the inhabitants with a reliable solution for the longevity of the building.

The Mastergold system offered a quick and easy installation process without compromising the long-term performance of the waterproofing. It also requires minimal maintenance – another reason why the system was the ideal solution. In total, 2,200m² of the Mastergold system was installed.

The warm roof system included only 5 elements. Alumasc’s Self-Adhesive Primer was used to condition the metal deck, then, to encapsulate the deck from flames the Euroroof Dual Bond Vapour Control Layer was installed. The Dual Bond VCL has a self-adhesive backing to the underside and a thermofusible upper surface which enabled the PIR BGT insulation to be bonded directly to the membrane.

To complete the warm roof system Mastergold Underlay was bonded to the BGT insulation which is torch receivable and the Mastergold Black Cap Sheet was then torched to the underlay providing a highly durable and effective solution.

The waterproofing is backed with an Alumasc 25-year system warranty, providing added peace of mind. The Euroroof Mastergold membrane offers high tensile strength and pliability and excellent resistance to puncture and UV degradation. The Euroroof Mastergold membrane is fully BBA approved and is tested for wind uplift and fire performance to meet with the current British Standards.
