How to insulate a garage floor

Uninsulated garage floors can become incredibly cold, so underfloor insulation is a must if you want your garage to be a viable living space during the winter months. We supply a range of excellent floor insulation boards for you to choose from, including the Celotex GA4000.

This PIR board is perfect for achieving that warm, welcoming feeling thanks to its fantastic performance, and its thin design ensures you’ll lose minimal space.

Once you’ve chosen the right garage floor insulation for your project, there are a few more things to consider.

If you’d like to retain the concrete slab floor of your garage, you should install a damp-proof membrane before any insulation.

Depending on the level of your garage floor in relation to the rest of your home, it may also be necessary to consider adding a step up between the rooms.
