Glass links & glass box roofs in Devizes: what is involved?
For Devizes homes and buildings we offer glass links & glass box roofs: frameless glass links joining old and new buildings. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Typical uses for glass links & glass box roofs include joining a period house to a new extension or annexe.
Devizes is around 27 km from Swindon, and we survey and fit throughout that part of Wiltshire, including the SN10 district.

Planning, building control and Devizes
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

Questions about glass links & glass box roofs in Devizes
How is the glass joined to the old wall?
Usually by a slim channel or flashing set into the masonry, sealed and weathered so the old wall can move without cracking the glass seal.
Do glass links need planning permission?
Often, yes — and listed building consent if either building is listed. We can provide drawings and product data for your application.
Is structural glass safe?
Structural glass is laminated so it stays in place if a ply breaks. The manufacturer designs it for the loads involved.
Do I need to be at home for the survey in Devizes?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
