Open the Window of Opportunity with Keylite’s New Mini Dormer System
Keylite’s pioneering Mini Dormer System can be built on the ground saving house builders time, cost and space, while improving safety on site. Developed in partnership with Keylite’s sister company Smartroof, the brands combined the talents of both R&D departments to develop a product fit for the Future Homes Standard.
As well as ensuring a watertight installation, the system can be conveniently built on the ground, saving build time and improving safety for contractors working on site. To further aid installation, the kit has been designed to fit on a roof from 10 degrees to 75 degrees, with a straightforward fitting process of just a few easy steps.
Everything, from the timber upstand and roof windows to the brackets and aluminium that goes around the roof tiles, is included within the Mini Dormer System kit, making construction and installation as straightforward as possible for house builders and contractors.
Keylite roof windows are CE marked, meet BBA Approval and adhere to standard ISO 9001:2015. The Keylite Mini Dormer System has also been through condensation risk analysis and raised no concerns.
For house builders concerned about thermal efficency, Keylite’s new system has a excellent thermal performance on both the wall cheeks and roof – resulting in maximum heat loss protection to keep a space warmer for longer.
Keylite’s Mini Dormer System also adds 25 per cent more daylight to a room. A typical dormer would have a glazed area of approximately 1.5m2 , whereas Keylite’s new system will provide 1.9m2 .
Plus, every Keylite Roof Window is fitted with an Integrated Expanding Thermal Collar as standard, which improves thermal performance and helps house builders achieve Part L of the Building Regulations. Keylite is also working on integrating its new Mini Dormer System with solar panels, ahead of the 2025 Future Homes Standard (FHS).
Whilst the standard roof window sits a lot lower in the roof; this new system has lifted the head of the window up out of the roof – gaining significant head space and providing an extra benefit for potential buyers.
The opening on the system has a handle that is conveniently placed at the top of the window, which controls ventilation, giving the option of fresh air flow even when the window is locked and secure. This can give peace-of mind for occupants with young children and also aid house builders in the selling process.
Colin Wells, Head of Technical at Keylite, comments: “ The Mini Dormer System has been designed to perform thermally, be watertight and provide more daylight. The product’s logistics help to save fuel on transportation and save space on site. Plus, installers are not at risk of having to work at height, as the timber structure and windows can be installed on the ground on a cassette type roof before the system is craned up on to the roof. Smartroof was the first brand to use the product on a trial site and found the installation process had significantly improved compared to that of traditional prefab dormers. The Mini Dormer System is the perfect practical solution for house builders wanting to create a well-ventilated and bright space for end-users.
