Insulation is a critical component of every house in the United Kingdom. Certain sections of your home, such as the loft or walls, may already be insulated. This is done to create a pleasant atmosphere for you and your family.

Why Not Insulate Conservatory

So if you insulate the rest of your home, why would you not insulate your conservatory? Many people don’t and this is why their conservatories are unpleasantly cold in winter and warm in summer.

By insulating a conservatory roof, you can potentially transform your room. Temperature wise, it could allow you to use it all year round rather than just in Spring or Autumn. There are other advantages too such as noise reduction, lower energy bills and stopping sun bleaching.

How Much Heat Does Conservatory Insulation Save?

In the winter, a 4m by 5m glass conservatory would most likely need roughly 3kW of heating.

  • The identical room with conservatory insulation will need about 2.7kW, so anticipate a 10% saving.
  • The identical space with a solid roof would need roughly 2.5kW, resulting in a 16 percent savings by utilizing just insulation.

The maximum that can be saved by insulating a conservatory roof is around 600kW per year. This is the equivalent of around £40. Whilst this is not a huge amount, this number is only going to rise with the current energy crisis we are experiencing in the UK.
