How to choose insulation for your conservatory roof

Roof insulation is one of the best ways to prevent warm air from leaving your home and reducing your energy bills. This eco-friendly way to retain heat can also help keep homes cooler in warmer months, which is why if you’ve opted for solid roof tiles for your conservatory, it is worth adding insulation.

An insular roof layer installed underneath your solid roof will help prevent heat from escaping from your conservatory during the colder months and help keep the room cool during the summers (a time when conservatories can often overheat), which allows you to make the most of the home extension.

Insulation Options

There are plenty of options to choose from when insulating your home, but when it comes you preventing escaping heat in your conservatory, you should ensure that you choose insulation that has the following qualities:


Much like the roof tiles you use, the roof insulation in your conservatory needs to be lightweight so it isn’t too heavy for the walls to support. Choosing a lightweight insulation will prevent damage to the structure of the conservatory.

Water vapour resistant

Conservatories can be damper than other rooms in your home as warm moist air from the rest of your home can flow into your conservatory and condense because of the change in temperature. Because of this, you should choose insulation that is resistant to water vapour to prevent it needing premature replacement.

Thin insulation

Regardless of the design of your conservatory, it is worth choosing a thin but effective insulation that takes up minimal space in your conservatory. The thinner the insulation, the lighter it is likely to be, meaning that you don’t have to worry about placing too much weight on the walls of your conservatory.
