Huge Range of Roof Windows
Sterlingbuild vans make VELUX window, pitched roof skylight and flat rooflight deliveries to London every day for loft conversion and kitchen extension projects.
What's Your Home Improvement Project?
If you're looking for a VELUX window to install in a loft bedroom, we recommend VELUX GPL 2060 top hung windowswith comfort glazing. Not only do they look great, they will help keep heat loss down and neighbourhood noise out. The top hung design means you get more headspace and better views.
For a touch of technology and luxury, opt for VELUX INTEGRA remote control windows. They will flood your home with fresh air or close blinds at the touch of a button. You can programme VELUX INTEGRA windows to open and close at certain times of the day, and a rain sensor will ensure your home is protected should the weather turn.
Or are you building or renovating a flat roof extension?
In that case, you'll need an energy efficient rooflight. A stylish flat glass rooflight will add up to 3 times more daylight than vertical windows and subtly fit into your flat roof. A lantern roof window will add a stunning finish to your kitchen extension. Budget-friendly ECO+ roof lanterns have more glass, less frame for more daylight and views.
Deliveries to London Every Day
Once you've chosen your window, select your delivery option. Most products on Sterlingbuild are available with next day delivery or FREE standard delivery, which is normally 2 or 3 working days depending on our suppliers' lead times.
