How To Insulate Your Conservatory
Conservatories are a popular addition to many houses and, if done correctly, can be a fantastic way to add value to your home. However, many people find that at certain times of year their conservatory becomes unusable. This is usually due to improper insulation that makes the room too hot in the summer heat and too cold in the winter.
A properly insulated conservatory has many benefits: aside from being able to use your conservatory all year round, it can also save you money on your bills by being far more energy efficient. It should also provide better noise insulation so you can enjoy a quiet and peaceful conservatory.
While this site is all about conservatory roof replacement and how it can help insulate your conservatory, there are other things you can do.
We thought it would be useful to give you a bit of a run down of some of the main ways people look to insulate their conservatories....
Whether you are considering building a conservatory extension or have an existing conservatory, there are many factors to consider when it comes to insulation. It is a different process to insulating a room within your house, with many different aspects that wouldn’t normally be present.
Different methods of insulation will also come with different costs and benefits so research into what best suits your needs is vital. It is also important to check building regulations in your area as they will provide information on the minimum insulation requirements necessary. These types of regulations do not apply to conservatory extensions of under 30sq metres.
One way of increasing insulation efficiency to consider is the floor. Adding 100mm of polystyrene before concrete is laid can be an eco-friendly and affordable way to insulate a conservatory floor. Underfloor heating installed after the concrete has been poured is another step you can take to create a warm, welcoming room. However, modifying a poorly insulated floor after a conservatory is built will be considerably more difficult and costly than insulating a floor during the building process, so this is something to consider as early as possible.
Walls and Windows
In terms of wall insulation, it is advisable to install an insulated cavity into the elevated dwarf-wall. It is then possible to further improve insulation by adding thermal uPVC or polycarbonate panels which trap heat. The standard choice for conservatory windows tends to be double glazing, but in the long run triple glazing is worth the extra cost for the insulation it provides.
Another popular method amongst builders is the use of argon gas to fill windows. The odourless, colourless gas is used between window panes to increase energy efficiency, reduce frost forming on windows, and increase sound insulation. As another step, windows can also be glazed with an energy efficient glazing that reflects heat back into the room.
There is a vast number of options available to you when it comes to roof insulation. Polycarbonate or glass are both popular and can be strong options. When looking at the quality of insulation you might want to consider the U-value of a given material. The U-value indicates effectiveness as an insulator so when thinking about what is best for your conservatory, the lower the U-value the better. Standard polycarbonate roofs have the highest U-value and therefore the most heat loss, but insulation increases with thickness with the ideal being 32-35mm.
A solid or tiled roof may be a better option for many as a lightweight metal roof is strong, durable, and doesn’t pose the problem of damp that is common with other methods of insulation. Insulated ceilings, for example, can be a fantastic way to insulate a conservatory by adding traditional insulation between the rafters and covering with a new ceiling. This leaves you with a warmer space with less light and presents the potential problem of damp and condensation.
A final method of insulation is to install insulated blinds between the rafters to reduce the amount of heat that escapes. It is unlikely to provide enough insulation to make the conservatory habitable in the peak of winter but provides an affordable and easy solution to slightly improve the insulation quality of your conservatory.
