Glass links & glass box roofs for Blackburn: the essentials
Our glass links & glass box roofs service in Blackburn covers frameless glass links joining old and new buildings. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. In Blackburn, as anywhere, glass links & glass box roofs are the usual choice for listed and period buildings where the old wall should stay visible.
Blackburn is around 15 km from Preston, and we survey and fit throughout that part of Lancashire, including the BB1 district.

Planning and building rules for Blackburn
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.

Glass links & glass box roofs in Blackburn: questions
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
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.
Can a glass link be warm enough to use all year?
With insulated glass units, solar control and good detailing, yes — though it will always be brighter and more exposed to temperature swings than a solid room.
Do I need to be at home for the survey in Blackburn?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Blackburn free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
