What do glass links & glass box roofs in Cowes involve?
Glass links & glass box roofs in Cowes means frameless glass links joining old and new buildings. We cover the PO31 district and the rest of the Isle of Wight, with a survey before any price is fixed.

From Cowes to Newport, Isle of Wight, Ryde and Gosport, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Cowes
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
