Frameless structural rooflights in Letchworth Garden City: what is involved?
We handle frameless structural rooflights across Hertfordshire, including Letchworth Garden City. In short: minimal glass rooflights with no visible frame from inside. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for frameless structural rooflights include rooms where you want sky without a visible frame.
Letchworth Garden City is around 38 km from Watford, and we survey and fit throughout that part of Hertfordshire, including the SG6 district.

Planning and building rules for Letchworth Garden City
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Frameless structural rooflights in Letchworth Garden City: questions
Will I see the edge of the glass?
From inside, the reveal is finished up to the glass so the edge is hidden. From outside you will see the glass and its edge seal.
How is it lifted onto the roof?
Larger panes go up with a vacuum lifter, a hoist or a crane. We plan access at survey.
Can it open?
Some frameless designs include a sliding or hinged opening element, but most are fixed. Pair with an opening unit if you need ventilation.
Is the survey in Letchworth Garden City free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.

Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
