Compared to uPVC or wooden frame vertical windows, a rooflight on your flat roof can not only be the cheaper option, it will be one that will add a dramatic difference to your living space:

2. If your room faces north, a rooflight will let in much needed daylight whilst vertical windows wont
3. Views and light won't be restricted by surrounding trees and buildings
4. Extending your home can make the original space darker, a rooflight will channel daylight deeper into your home
5. Views of the skies will make your room feel bigger

We offer a wide choice of styles that will complement your space or create an eye catching feature.

Fixed or Opening?

Make the most of your rooflight by opting for an opening model. It will help maintain the comfort and temperature of your kitchen or living space year round by creating a chimney effect. 

The next decision to make is manual, electric or solar? If your budget isn't limited or opening the rooflight by hand is difficult - or even if you would  enjoy a touch of luxury or the latest in gadgets - an electric or solar powered window is for you!

Sterlingbuild Tip! Mix and match a fixed rooflight with an opening one to maximise the health of your room. You'll enjoy a huge amount of daylight as well as fresh air.

Size or Quantity?

Is bigger always better? Not always because for some rooms, more is better.

Electric and solar powered windows are easily operated by a handheld control pad or wall switch, making it much easier to open and close windows and blinds. Pre-installed rain sensors will close the window at the first sign of rain.

Yes, the dimension of your rooflight will have an impact on the amount of daylight in your room, but in some cases, using more than one smaller size rooflights will increase the amount of daylight.

Sterlingbuild Tip! Aim for 20% of the roof area to be window, which will ensure a good distribution of light.
