Do Thermal Conservatory Blinds Improve Insulation?

Posted: 24 Oct 2023

In terms of temperature, conservatories are known for being rather volatile they can become very warm in the summer or very cold in the winter. This is due to glass letting a lot of heat through, whether that be in or out of your room. This leaves many people looking for solutions and asking, do thermal conservatory blinds improve insulation?

The answer is that thermal conservatory blinds can make an incredible difference in your conservatory’s temperature. With the right blinds insulating the conservatory throughout the year you can conserve heat in the summer and block it out in the summer, should you wish to do so. But with so many blind types available, what blinds are the best for insulating your conservatory?

pure™ Pleated Blinds for a Conservatory

One of the most popular blinds for conservatories, our unique pure™ Pleated Blinds are excellent for insulation. We have specifically designed The Solar Design™ fabrics for conservatories, so they absorb a lot of heat, preventing it from going through the glass.

Because most of the heat in a conservatory escapes and enters through the roof, the best insulating blinds are ones that work well as roof blinds. We have designed our pure™ Pleated Blinds to fit into the awkward shapes found in conservatory roofs, so there is as little exposed glass as possible – meaning there are fewer areas for heat to get through.

pure™ Pinoleum Blinds for a Conservatory

Popular in timber conservatories and orangeries, pure™ Pinoleum Blinds are also excellent for insulation. The natural heat absorption of wood, especially Basswood, means that wood blinds often outperform fabrics when it comes to heat loss. However, with the addition of optional Solar Lining, pure™ Pinoleum Blinds become some of the best insulating blinds available.

Like the pure™ Pleated Blinds, we have also designed for them to fit into awkward shapes in conservatory roofs; letting as little heat through as possible.

Pinoleum Roof and Side Blinds

Duette® Blinds for a Conservatory

Duette® blinds have a honeycomb structure, which means air is trapped between the two layers of fabric. This makes them very energy efficient and excellent at insulation. The fabrics design also means it can reflect the sun, so they’re very efficient in the summer too.

Remote Control Roof Blinds

Roller Blinds for a Conservatory

Although they create an area of trapped air between the blind and the glass, roller blinds are often fitted so far away that the insulation effects are diminished. They also usually have large gaps between each blind, letting heat and light through.

We also do not recommend roller blinds for conservatory roofs, which makes them unable to cover the main part of a conservatory that needs insulation.

Vertical Blinds for a Conservatory

Vertical blinds are very poor at insulating a conservatory, except at providing basic shade when used as window blinds.

Excellent. Really helpful company. We have put blinds in the whole of our new-build house. All are thermal. Colour range was great and they went out of their way to match the colour that I wanted in the living room.

I hadn’t ever bought conservatory blinds before but this company made the process very straightforward. The fitter Richard was extremely helpful and has done an excellent job. I’m very happy with the blinds, both the quality and the fitting.
