What are frameless structural rooflights?
Across County Down, our frameless structural rooflights work covers minimal glass rooflights with no visible frame from inside. Survey first, fixed price second, fitting third.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Bungalows are widespread in Northern Ireland, and sun tunnels or roof windows are an easy way to brighten internal hallways.

Planning and building rules in Northern Ireland
Northern Ireland's householder permitted development allows rooflights within limits — no more than 15 cm projection on road-facing slopes and a 0.5 m margin from ridge, eaves and party walls. A side-facing window within 15 m of a neighbouring boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Northern Ireland's energy rules assess rooflight U-values in the vertical position — unlike England and Wales — and expect 1.6 W/m²K or Band C for replacements. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
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 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.
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.
Is frameless glass as strong as a framed rooflight?
Yes — it is structural glass designed for the job. The support is hidden rather than missing.
Do I need to be at home for the survey in County Down?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
