Frameless structural rooflights in Carrickfergus: what is involved?
Frameless structural rooflights in Carrickfergus means minimal glass rooflights with no visible frame from inside. We cover the BT38 district and the rest of County Antrim, with a survey before any price is fixed.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
Carrickfergus sits about 9 km from Newtownabbey and 11 km from Bangor, County Down, and we cover the whole BT38 postcode district and the roads in between.

Do you need permission in Carrickfergus?
Most rooflights on houses in Northern Ireland are permitted development under Class B, but not in a conservation area or on a listed building's curtilage. 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.
Technical Booklet F1 (2022) asks for replacement windows and rooflights in existing homes to reach WER Band C or a U-value of 1.6 W/m²K, assessed in the vertical position. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.

Questions about frameless structural rooflights in Carrickfergus
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.
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
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 you work alongside my builder in Carrickfergus?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Carrickfergus?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
