What do frameless structural rooflights in Cheshunt involve?
Thinking about frameless structural rooflights in Cheshunt? The short answer: minimal glass rooflights with no visible frame from inside. The longer answer depends on your roof, which is why we survey before we price.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Cheshunt, as anywhere, frameless structural rooflights are the usual choice for architect-led extensions and long slots of light over islands or along party walls.
Jobs in Cheshunt 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.

Planning, building control and Cheshunt
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Questions about frameless structural rooflights in Cheshunt
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.
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.
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
Can you work alongside my builder in Cheshunt?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Cheshunt?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
