With a concept in mind to provide an insulating solution that would also help the new-build development to blend in with its surroundings, it was decided that a green roof system would be installed on top of the built-up StressPly Flex Plus system.
The environmentally friendly layer of insulation would help to keep the heating costs down during the winter months and maintain the picturesque views over the bay for the other hotel guests and the surrounding community. The Garland UK Approved Contractor, Western Contracting, installed a layer of StressPly Evolution base sheet directly to the installed SIP frame and finished this with a mineral covered layer of StressPly Flex. This gave the roof a solid waterproofing layer to which the green roof system could be directly applied.
The Technical Manager proposed a unique green roof solution that would greatly reduce the overall weight of the system, ensuring the structural integrity of the development was not compromised. By specifying a mineral wool substrate rather than a traditional compost, less stress was added to the final roof structure, whilst still guaranteeing optimum thermal efficiency for the building.
It was essential for extra measures to be taken to ensure that the green roof was protected as much as possible from the weather elements. The new-build apartments were beach facing and susceptible to strong offshore winds, so to protect the edges of the green roof system from any potential uplift, a natural solution in the form of large pebbles were hand-laid, to secure the vegetation as much as possible.
