Why do conservatories get so hot?
Reduce heat and glare with conservatory window film
Conservatories are designed to be bright, relaxing living spaces, but they can quickly overheat and become uncomfortable — even unusable. So why do conservatories get so hot, and how can conservatory window film help?
The appeal of a conservatory, orangery or garden room lies in its large glazed areas, with expansive windows forming most of the walls and roof. This design allows natural light to flood the space and provides uninterrupted views of the outdoors. However, it also allows solar energy to pass through the glass and build up inside, steadily increasing the internal temperature.
During summer and warmer periods, this effect becomes more noticeable. Extended daylight hours and strong sunlight can cause temperatures inside a conservatory to rise rapidly. A professionally installed conservatory window film provides an effective heat reduction solution without replacing the glazing.
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.
Options for conservatory cooling window films
The correct film depends on the material used in your conservatory roof.
Glass conservatory roofs
A high-performance solar control window film such as Supertint Glass is applied internally and gives the exterior a subtle reflective appearance. This helps reject solar energy before it enters the conservatory, reducing heat while maintaining natural light and outward visibility.
Polycarbonate conservatory roofs
Specialist films such as Supertint Poly are designed specifically for polycarbonate roof panels. Applied internally, they help reject solar energy and reduce glare while still allowing good light transmission.
Both solutions are designed to reduce excess heat without making the room feel cold, allowing you to enjoy a more comfortable environment throughout the year.
Additional benefits of conservatory window film
Installing conservatory window film provides more than just heat reduction.
-
Glare reduction: Helps improve comfort when reading, working or using screens
-
UV protection: Blocks up to 99% of harmful UV rays, helping prevent fading
-
Improved usability: Makes conservatories more comfortable year-round
-
Energy efficiency: Reduces reliance on cooling systems
Sunlight entering through large glazed areas can create significant glare at different times of day. Solar control film helps filter harsh sunlight, improving comfort and usability.
UV rays, heat and light are also key causes of fading to furniture, flooring and fabrics. Conservatory window film helps slow this process and protect interiors.
A cost-effective alternative to blinds or replacement roofs
Compared with blinds, air conditioning or replacement solid conservatory roofs, window film is a cost-effective heat reduction solution. Installation is straightforward, requires no structural alterations and delivers immediate results.
Solid roof systems are often designed primarily to improve insulation in winter, whereas solar control window film specifically targets heat build-up from sunlight in warmer months.
Conservatory window film installation
DIY conservatory window film is available with fitting instructions, but installation can be challenging due to roof height and angles. Professional installation ensures the best performance and finish.
Nationwide installation teams can apply conservatory window film quickly and safely, helping transform an overheated conservatory into a usable, comfortable living space.
