Adding best insulation for timber frame to your loft can make an enormous difference to the warmth of your home. It captures heat normally lost through your roof and stops draughts getting in too. It also helps to reduce energy costs, saving you hundreds over a year and even thousands over a ten-year period. It also contributes to an environmentally sustainable lifestyle, mitigating carbon emissions and helping reduce global warming.

Insulation is available in a variety of forms to suit different purposes, with the most common being blanket insulation rolls, which can be cut to size and then placed between and across your joists. Another popular type of insulation is sheep’s wool which, as the name suggests, contains soft and natural fibres. This is safe to handle and will not irritate skin, allowing you to install it without the need for protective clothing. It also wicks moisture, which can help prevent mould and rot in the loft space.

Best Practices: Insulation Choices for Timber Frame Construction

It is important to note that you should not put a floor directly on top of your insulation, as it is essential to ensure there is an adequate gap for airflow. However, if you do plan to install a loft floor over the insulation, then we would recommend using products such as Loft Legs to create a safe raised loft floor, which can carry the weight of your belongings.

A breathable vapour control layer is also essential to allow water vapour to escape from the building. This can be made from any hygroscopic material such as sheep’s wool (it must be treated to prevent moths), cotton, wood fibre or Jute insulation which will regulate humidity levels by absorbing and releasing water vapour as needed.
