Roof Windows
Roof windows, often confused with skylights, are a great option for when you want to allow both light, fresh air and space into your home. A skylight is a fixed window that doesn’t open. Whereas roof windows do open, allowing the option to encourage fresh air movement as well as natural light.
At Howarth, we provide Velux windows and Keylite roof windows which come in a variety of finishes, styles and glazing options. They also have a vast majority of features, with examples including an expanding thermal collar, Flick-Kit brackets, Click Fit Hoods and Warm Edge Glazing. Roof windows come in different types, ranging from centre pivot roof windows, top hung/fire escape, and conservation. We also offer flat roof windows, which are manufactured to be high-quality, and pleasing to the eye.
We also offer several different finishes, such as Polar White PVC, white painted pine, and clear lacquered pine. Each finish has its own benefits, but no matter what you decide to choose, you can be sure that the roof window will transform and elevate the overall appearance of your room.
Velux often supply their windows as top or bottom windows, which solely depends on the angle of your roof to what window operation you will need. Centre pivot windows are suitable for roof pitches between 15-90 degrees; however, top hung windows are suitable for roof pitches between 15-55 degrees. Velux also offer control modes, such as manual, solar powered, and electric. Electric roof windows open and close with just one touch of the pre-paired wall switch, which is perfect for out of reach areas. Solar powered windows also offer this functionality, but you don’t need to plug it into a power supply, which makes installation even quicker than other control modes. The control modes for the roof windows are manual, electric kits with a wall switch, and premium electric kits with a rain sensor.
For further information and expert advice regarding roof windows, please contact your friendly local Howarth branch.
