What is Loft Insulation?

Loft insulation refers to the process of adding insulating material to the space between the top floor ceiling and the roof of a building.  A loft can be insulated up to 400mm in thickness, using materials such as Knauf mineral wool. The insulation is rolled out in between the roof joists or rafters. It acts as a barrier, slowing down the transfer of heat through the roof structure.

When choosing loft insulation materials, factors such as R-value (the measure of thermal resistance), cost, ease of installation, and environmental impact should be considered.

Here at ProGuard Exteriors we’re happy to talk you through the options, ensuring the most suitable solution for your specific needs and budget.

Benefits of Loft Insulation

Saves You Money

Because a reduction in heat loss means a warmer home, you won't need to use nearly as much heating, which in turn will significantly lower your heating bills.

Improved Comfort

Insulated lofts help maintain a more consistent indoor temperature year-round, making living spaces cosier in winter and cooler in summer.

A Greener Home

Reduced energy consumption via less heating/cooling leads to lower carbon emissions, contributing to efforts to combat climate change.

Condensation Prevention

Loft insulation can help prevent condensation build-up within the property, reducing the risk of mould and dampness.


The process usually takes around 1 day and is installed by qualified fitters, making sure to cover lights and pipes correctly, and fit the insulation evenly throughout.

For loft insulation to be installed, the loft needs to be empty and clutter free. Other installation options include the following.

Insulated Loft Hatch

Adding an insulated loft hatch is the ideal finishing touch for thorough loft insulation, with no cold spots.

Boarding Over Insulation

This can increase the insulation effectiveness further and is ideal when utilising the loft space as storage; but it must be installed correctly, ensuring that the boards do not sit directly on the insulation material.

Loft Conversions

If your loft has been converted into an extra room it's still important to add insulation, this can be done within the floor and between or over the rafters.
