How To Keep A conservatory Cool

Put Up Conservatory Blinds

Installing conservatory blinds helps to keep a conservatory cool by preventing the suns rays from fully entering the room which will help to regulate the temperature and protect the furniture in the room from fading in the sun.

Blinds can also be aesthetically pleasing as well as practical in both the summer and the winter. During the winter blinds will prevent heat from escaping and help to keep your conservatory warmer.

Install Air Conditioning

Portable air conditioning units are affordable with some units starting from as little as £250 making them an inexpensive way of cooling a conservatory down.
The main drawback to portable air conditioning units is that they are incredibly noisy. I have installed one in my bedroom and it’s nice to take the heat out of the room before going to bed, but it would be difficult to sleep with it running.

Some of the more expensive portable air conditioning units are triple function, air conditioning, heating or dehumidify.

Portable air conditioners (PACs) are measured in British Thermal Units (BTU). The higher the BTU number the larger the room can be cooled. The higher the BTU the bigger the price tag. As a rough guide, a 9,000 BTU air conditioner will efficiently cool a room of 40 cubic metres, measure your room to work out what size air PAC you will require.

Most portable air conditioners range from 50-55 decibels, the more you spend the quieter the machine will be – This video will give you an idea of the air conditioner noise when running:

Cooling Film Can Keep A Conservatory Cool

Modern glazing already has a layer that acts in the same way as ‘Cooling film’ or ‘solar window film which is an aftermarket adhesive layer that is added to older conservatory roofs resulting in around 78% of the sun’s rays being reflected away from the conservatory roof.

If you are looking for an inexpensive way to keep a conservatory cool then this could be the solution for you, with prices starting at around £15 per roll this D.I.Y method could save you money.

There is also a film that can be used on a polycarbonate roof which will also reflect up to 75% of the suns rays.

If you are reading this article then your conservatory most likely has have either an older glass or polycarbonate roof as they both haved poor insulating properties and allow sunlight to enter into the room heating it up making it too hot in the summer, and allowing heat to escape in the winter.
