Mastergold warm roof system protects the £12 million new build primary school in the coastal village of Hakin, Pembrokeshire.
Gelliswick Church in Wales VC School required a roofing system that would provide inhabitants with a reliable solution for the longevity of the building. The fully warranted Mastergold warm roof system was the ideal solution for the project.

school with warm roof

The voluntary controlled primary school was formed following the decision to discontinue two nearby schools, the new school entity was established on 1st September 2017, with the school operating across the three existing sites. It was of the school’s interest to quickly relocate the students and staff from the other two sites to the new build, which opened in January 2018. This Mastergold system offers 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

2,200m² of the Mastergold system was installed . The warm roof system included only 5 elements. Self-Adhesive Primer was used to condition the metal deck, then, to encapsulate the deck from flames the 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 a 25-year system warranty, providing added peace of mind. The Mastergold membrane offers high tensile strength and pliability and excellent resistance to puncture and UV degradation. The Mastergold membrane is fully BBA approved and is tested for wind uplift and fire performance to meet with the current British Standards.
