Understanding excess heat build up in conservatories

Why does my conservatory overheat?

One of the main benefits of conservatories are their glass or polycarbonate roofs and large windows, all of which combine to deliver a bright and airy environment.

Left untreated however, heat will steadily pass through the windows and roof, raising the internal temperature until it quickly becomes uncomfortable.

Without taking measures to reduce or slow down the heat passing through roofs and windows, your conservatory will always end up experiencing high, often uncomfortable temperatures.

An application of window film will help.

Why should you choose window film?

Five reasons to use window film in your overheating conservatory

1. It's effective immediately. The film will get to work as soon as it is in place, reducing excess heat build up and the internal temperature.

2. Beat the heat, keep your view. Conservatory window films will allow for a daytime view out and will not stop natural light from passing through.

3. Multiple benefits. In addition to reducing excess heat levels, window films for conservatories will cut down on glare and block the majority of potentially harmful UV rays.

4. Glass or polycarbonate. The Window Film Company offers heat reducing window film for use on glass and polycarbomate surfaces.

5. Fully installed or DIY. You can choose to fit the window film yourself, or take advantage of our nationwide installation service and have one of our expert fitting teams install the film to your conservatory for you.

What is conservatory window film?

Conservatory window film is a specialist solar control film designed for application to glass and polycarbonate roofs. Applied directly to the internal surface, it helps reflect and absorb solar energy before it enters the room, reducing heat build-up and improving comfort.

Because it sits directly on the glazing, window film is typically more effective and more cost-efficient than blinds. Blinds are positioned away from the glass, allowing heat to pass through and become trapped inside. They can also block light and restrict the view, whereas solar control window film maintains brightness and usability.

Cost-effective alternative to blinds or replacement conservatory glass

Window film is cheaper and easier to install than blinds, as well as delivering additional benefits benefits that blinds cannot. 

While blinds will still allow heat to pass through the glass and will block natural light and the view when closed, window film rejects solar energy before it can enter your conservatory, and does so without blocking the daytime view or sacrificing high levels of natural light.
