Glass links & glass box roofs for Leigh: the essentials
We handle glass links & glass box roofs across Greater Manchester, including Leigh. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Typical uses for glass links & glass box roofs include joining a period house to a new extension or annexe.
We work across Greater Manchester, including Leigh, and in neighbouring towns such as Atherton and Tyldesley. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Frameless sliding or pivot doors
- Heated glass on some systems
- Frameless or slim-framed glass
- Structural glass beams and fins
- Concealed gutters and drainage
- Structural glass roof with concealed fixings
- Bright circulation space
Things we check at survey
- Structural calculations are part of the design
- Thermal performance of large glass areas must be calculated
Planning and building rules for Leigh
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.
