How we approach frameless structural rooflights in Marlborough
Our frameless structural rooflights service in Marlborough covers minimal glass rooflights with no visible frame from inside. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Frameless structural rooflights suit architect-led extensions and long slots of light over islands or along party walls.
We work across Wiltshire, including Marlborough, and in neighbouring towns such as Swindon and Devizes. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Marlborough
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
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.
Read the planning permission guide before you commit to a design.

Questions about frameless structural rooflights in Marlborough
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
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.
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.
