Glass links & glass box roofs in Sudbury: what is involved?
Thinking about glass links & glass box roofs in Sudbury? The short answer: frameless glass links joining old and new buildings. The longer answer depends on your roof, which is why we survey before we price.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Typical uses for glass links & glass box roofs include joining a period house to a new extension or annexe.
We work across Suffolk, including Sudbury, and in neighbouring towns such as Colchester and Haverhill. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Concealed gutters and drainage
- Solar-control and low-iron glass
- Heated glass on some systems
- Frameless sliding or pivot doors
- Structural glass beams and fins
- Designed around the existing building
- Keeps period walls on show
Before you order: points to check
- Structural calculations are part of the design
- Thermal performance of large glass areas must be calculated
Planning, building control and Sudbury
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.
