Mould is very common in conservatories and glass rooms, this is due to the relatively high humidity within the room and lack of roof insulation. Condensation forms when warm, moist air comes into contact with a cooler surface, causing the water vapor in the air to change from a gas to a liquid. 

 We are regularly asked what's the best way to reduce mould growth. Our answer is to allow the room to ventilate and breath when the weather is dry, this can be achieved by opening small windows to the first safety catch at opposite ends of the room. If however the weather is particularly wet, a dehumidifier would be the best course of action. We don't recommend the smaller window sill units as sold on Amazon. We recommend at least an 8 liter per day removal dehumidifier with an automatic run function. This will greatly reduce both the damp and humidity in the room, slowing down and preventing mould growth. 

 

If you have conservatory roof blinds installed we recommend opening them to approximately ⅔. This allows more air to flow around the blinds. Condensation will still form at the lower end of each panel however and will likely lead to mould growth on the conservatory and the blind fabric. We can apply a "waterproof" coating to the blinds if less that 3 years old. This helps prevent mould from staining the fabric but also prevents bug stains.
