Why is Loft Ventilation Important?

April 5, 2017 11:55 am

Efficient ventilation is a very important factor when converting your loft space, but is unfortunately often overlooked during the planning stages. By introducing a new room into a former open cold roof space, you will limit the circulation of natural ventilation through the roof. This could lead to condensation and without adequate ventilation you could end up with dampness and mould growth that will eventually cause rotting timbers. This is dangerous to both the structure of the roof and the health of the property’s inhabitants.

During the construction phase you should make sure the ceiling is well-sealed with ventilation openings to enable sufficient free air movement through the gap between the insulation and the underlay. Ventilating your roof will often require the help of an experienced professional.

There are several ways other ways to ensure there is proper ventilation in your loft conversion and the methods you opt for depend largely on what purpose you have in mind for the converted loft space. Condensation is certainly to be expected if you’re going to use the space as a bathroom or kitchen, where considerable amounts of water vapour will be produced. If that is the case, then you will need to install an extractor fan to expel as much moisture as possible. There are many different fans to choose from, such as silent fans and centrifugal fans. Speak to an expert if you are unsure which type of fan is right for your project.

Inadequate heating is also a large contributor to problems with condensation and damp, so it’s important to make sure your loft conversion is heated sufficiently. This might mean fitting an additional radiator into the room, or you could even consider easy-to-install underfloor heating mats.

You could also purchase an electrical dehumidifier. These are designed to decrease the amount of water vapour in the air and can even be used in the colder, rainier months when you may prefer not to open a window.
