Glass links & glass box roofs for Kendal: the essentials
We handle glass links & glass box roofs across Cumbria, including Kendal. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Think of glass links & glass box roofs for joining a period house to a new extension or annexe.
Jobs in Kendal are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Solar-control and low-iron glass
- Structural glass beams and fins
- Heated glass on some systems
- Concealed gutters and drainage
- Frameless or slim-framed glass
- Designed around the existing building
- Keeps period walls on show
What to check first
- Thermal performance of large glass areas must be calculated
- Structural calculations are part of the design
Do you need permission in Kendal?
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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.
Read the planning permission guide before you commit to a design.

Questions about glass links & glass box roofs in Kendal
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.
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.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
Do I need to be at home for the survey in Kendal?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Kendal?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
