Why Is My Conservatory Cold?

Your conservatory could be could for numerous reasons, poor performance can be caused by poor installation as well as the building materials.


If your conservatory has a polycarbonate roof it has no thermal resistance, this allows heat from your home to escape via the roof as well as allowing the cold to enter. Polycarbonate is an inexpensive material that has almost zero insulating properties, allowing cold air to enter your home. During the summer months, polycarbonate roofs allow the heat to enter the room with very little resistance leaving homewoners seeking ways to keep a conservatory cool.


Build issues account for a large percentage of leaks and draughts, Polycarbonate for instance isn’t airtight, this encourages the build-up of condensation inside of the support beams, this may not sound like a serious issue but it can lead to expansion and subsequent cracking of the channels which creates draughts that enter your home causing it to feel cold and cost you money on energy bills.


Polycarbonate has a lifespan of around 10 years if it is well looked after, it becomes easily damaged in poor conditions which cause leaks and draughts.

Rubber seals can also be damaged when expeosed to the weather leading to water ingress or panels slipping. Whilst a good maintenance routine will extend the longetivity of your conservatory, it will not make a conservatory warmer without some extra steps.

Make A Conservatory feel Warmer With Accesories

As most heat is lost through the roof and the glazing, heat loss can be limited by installing conservatory blinds on both the roof and the windows and doors. These will also prevent excess heat from building up during the summer months, but a good quality blind must be used to prevent the sun from fading the colours.

Conservatory blinds can also be installed in our ‘Classic Conservatory Roof’ at the time of installation into specially designed tracks concealed within the glazing bars, these can also be retrofitted at a later date with ease thanks to this clever design. Blinds are recommended even with modern glass roofs because they can prevent furniture from becoming sun-bleached and offer a shaded area to sit out of the sun.


The right choice of furnishings can also make a conservatory warmer, strategically placed rugs and a throw on the seating can all create a feeling of warmth. This is more of a hack than a way to actually make a conservatory warmer, furnishings can be bleached by the sun or go mouldy in a cold conservatory. Updating to a modern conservatory roof is the best way to make a conservatory warmer.


Conservatory heaters can be expensive, you can buy a freestanding oil filled radiator which cost a few pence an hour to run and will make a conservatory warmer, reducing condensation and damp. These are a fantastic way to warm up a conservatory as they only cost around £30 to buy and take up very little space.

A Replacement Conservatory Roof Can Make A Conservatory Warmer

Perhaps the best way to make your conservatory warmer is with a replacement conservatory roof. The largest percentage of heat lost in your conservatory will be through the roof. Replacing a traditional polycarbonate or glass roof with a modern solid tiled conservatory roof will prevent any heat loss through the roof and prevent a build-up of heat during the summer.
