With standard loft boarding, loft boards are placed directly onto the joists. This is the fastest way to board a loft, however it isn’t suitable for the majority of lofts, especially if you have insulation, wiring, pipework or downlights installed.
Although some installers and joiners recommend standard boarding, mainly because it’s cheaper and easier to install compared to raised flooring, it can have adverse effects on your property. In our years as approved loft insulation installers we have had a lot of experience with lofts that have been boarded directly onto the joists and the problems that have arisen as a result, especially if the insulation has been squashed into place. This drastically reduces the air flow within the loft space, resulting in the build up of condensation, causing problems with dampness within the loft. If your insulation gets damp it will stop working and the weight and water will cause damage to your ceiling beneath. If the wooden joists get damp it may cost thousands to repair the damage caused by the damp.
To avoid these problems we install the Raised Floor Loft Boarding. This is usually in the central area of the loft, allowing for the air to flow from the eaves and continue throughout the loft and under the loft flooring, removing any risk or problems with damp or condensation.
