Flat Roof Windows

If you have a flat roof, opt for skylights as they apply to this type of construction. Skylights and flat roof windows are some of the best additions you can make to your flat roof to increase the amount of natural light coming into the room.

It’s best to use a mild detergent mixed with warm water to clean your rooflight. Any type of glass cleaning products work as well. You should make sure to use a soft cloth or sponge and remove any dirt from surfaces gently.

Flat rooflights are a great way to add lots of extra daylight into a room. They are especially suited to rooms with flat roofs above. Flat rooflights are available in a wide range of shapes, sizes and specifications, so we can create perfectly designed skylights for a flat roof, roof lanterns or roof lights for you.

The Flatglass Rooflights are designed to be installed onto 150mm upstand kerbs, so the kerb should be level in one plane. To ensure there is no ingression of water, it should also not be less than 150mm high. The top of the curb should be angled as a way to make water fall off as it does from a glass. The road also needs to show signs of aging.

Usually, we recommend that the kerbs be at least 75mm thick. This is to support the rooflight frame and to properly hide it from view from below.

Glass facades are ideal if you want a no-holds-barred view. Thicker kerbs can let in light from below, but they may compromise your view of the frame.

Always consult a building professional to ensure the suitability of the kerb before installing a rooflight. It must be strong enough to easily take the weight of the rooflight and any other loads imposed by wind or snow, for example. Before installing a rooflight, be sure to get signoff from a building professional. The kerb needs to be strong enough to take the weight of the rooflight and other loads that may be imposed by wind or snow, for example.

The long answer is yes, the tolerance has been built into this product and there are a number of factors that contribute to this. For example, if you provide us with finished weathered kerb dimensions equal to 1000mm down the slope by 2000mm long, we will fabricate a roof light that’s 1046mm x 2020mm. This means that the sloping roof light will slide easily over the curb, and be well-fitted to the top of the curb, like a box lid.

This might not seem so at first, but glass is actually a ductile material. Its rigidity depends on factors like its size and how many panes it has. The bigger the unit the less rigid, and it’ll deflect more with a heavier load.

When installed in the horizontal plane this means that the glass will start to dip. This is because of the dead load and also pressure from wind or snow.

Obviously, if a liquid like water were to be placed upon the glass, it will fill the dish and create a pooling effect.

If pooling water is to be eliminated, there needs to be a greater thickness of the outer skin of glass. This thickness will reduce deflection-boundless glazing. However, to make the rooflights safer, we heat-soak toughen the glass to make it stronger, but unfortunately this can introduce a bow in the glass.
