Glass links & glass box roofs in Hatfield: what is involved?
Our glass links & glass box roofs service in Hatfield 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Hatfield, as anywhere, glass links & glass box roofs are the usual choice for listed and period buildings where the old wall should stay visible.
Hatfield sits about 4 km from Welwyn Garden City and 8 km from St Albans, and we cover the whole AL10 postcode district and the roads in between.

- Heated glass on some systems
- Structural glass beams and fins

Planning, building control and Hatfield
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.

Glass links & glass box roofs in Hatfield: questions
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
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 the survey in Hatfield free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Hatfield?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
