About internal windows and borrowed light

An internal window is a fixed glazed panel set into an internal wall to borrow daylight from a bright room for a dark one — an inner hallway, a landing, a windowless bathroom or a box room. A glazed fanlight over a door does the same job. Full details on internal windows and borrowed light.

Internal windows and borrowed light for Cambridgeshire properties

Cambridgeshire's housing includes Victorian terraces off Mill Road, college-town period houses and new neighbourhoods at Eddington and Northstowe. Whatever the age of the property, we check the floor, walls and ceiling before anything is made, because internal glass is only as good as the opening it fits. We also work for local businesses, including science parks and lab-enabled offices around Cambridge, plus Peterborough's city-centre offices.

Questions from Cambridgeshire customers

Who fits internal windows and borrowed light in Cambridgeshire?

Our own installation team, working to the drawing agreed at survey. The same company quotes, manufactures and fits your glazing.

Lead time is typically 3–5 weeks from survey. We'll give you a firm date when you approve the drawing.

Does an internal window need Building Regulations approval?

Usually not on its own, but forming an opening in a load-bearing wall needs a lintel and Building Control sign-off. Glass near the floor must be safety glass.
