How To Stop Condensation in Your Conservatory: A Quick Guide


Condensation on conservatory windows is a common problem and can often be worse in the winter when the temperature is lower. Designed to be both watertight and airtight, a conservatory has no natural ventilation, which makes it prone to condensation – especially when the door from your home through to the conservatory is left closed most of the time. However, Ultraframe has expertly crafted a guide to help keep your conservatory condensation at bay. 


Ventilate Your Conservatory

The best way to keep your conservatory condensation free is to make sure the room is well ventilated. Keep the room warm and leave the windows ajar slightly: this may seem strange, but it will help air circulate and remove condensation.

If you're building a brand new conservatory or are planning on refurbishing an existing one, consider using trickle vents on the windows and doors, which will allow air to flow more freely than if the room had no ventilation whatsoever.

Ventilate your home when bathing, doing laundry and cooking –  to avoid the build up of excess water. Keep doors to the conservatory open so that air can flow freely. You'll find that the problem is reduced in a very short space of time.

If you are struggling with very bad condensation in your conservatory, a dehumidifier will help. Dehumidifiers remove excess moisture from the air, thereby preventing it from settling on the windows as condensation.

Roof vents will also help prevent the build up of condensation. Ultraframe can provide these vents in a manual format that’s spindle operated or an intelligent automatic format that reacts to rain and temperature changes.

Avoid The Overuse of Plants

Avoid filling your conservatory with too many plants, as they will contribute to the build up of condensation. If you are worried about your window frames, sills or carpets, you can buy products designed to soak up excess moisture.


Your Conservatory Design Matters

If your conservatory is no longer performing as it should, making the above changes may not have the impact you expected. For example, gaps in the installation may be allowing cold air in, and your doors, windows, and roof may no longer be providing acceptable levels of thermal efficiency.

Updating your conservatory is something you should investigate. With an approved Ultra Installer, Ultraframe will be able to recommend the best course of action. In the meantime, here are a few ideas for you to consider in light of your persistent condensation problem.


Replace Your Existing Conservatory Roof

Does your roof have trickle vents included as standard? All Ultraframe replacement conservatory roofs include these as standard –  which means you will benefit from a constant flow of fresh air that will help prevent condensation on your conservatory roof and windows.

A replacement roof designed and built by Ultraframe will include high performing glass that blocks out most solar rays during summer and prevents heat leakage at all other times. Meaning no matter how you occupy the space, it will remain at a comfortable temperature.


Have You thought About Bifolding Doors?

If you are yet to build a conservatory or have been told that a total rebuild is necessary, you may want to take a closer look at bifold doors. These open to almost threshold length and create a wide aperture that lets in lots of fresh air.

Catch Elusive Breezes with Tilt & Turn Windows

Tilt and turn windows open in more than one direction. The versatility of their design means that they can catch passing breezes and redirect them inside your conservatory. This feature is not achieved in most other window designs.


Ultraframe Products Have Been Designed to Prevent Condensation

Ultraframe conservatory products are designed, manufactured and rigorously tested to ensure they achieve maximum performance. For example, our Livinroof and Ultraroof systems expertly combine the very best attributes of a solid and glass conservatory roof – which means they return superb thermal performance but without the need to compromise on natural light.

The high performing glass used in these replacement roofs reduces reliance on heat during summer as warmth is generated organically instead. During winter, heat is expertly retained, but it’s never too hot, thanks to the trickle vents included as standard.
