Is underfloor insulation worth the investment?

home / Blog / Is underfloor insulation worth the investment?

Up to 15% of heat is lost from inadequately insulated floors

More often than not, underfloor insulation is overlooked as typically, when we’re feeling cold or uncomfortable at home; we associate heat loss with the walls, roof and windows/ doors.

Whilst the above is often the case and energy can escape through various parts of a buildings fabric. It is equally important for homeowners to check that their floors are adequately insulated either at construction stage (if solid) or by having this retrofitted for existing buildings (if suspended)

Signals that may indicate that you need underfloor insulation installed at your home:

  • You’re experiencing fluctuations with indoor temperatures throughout the day or struggle to maintain a comfortable indoor temperature even with the heating on

  • You can feel cold spots and/or draughts at floor level

  • You have noisy or ‘creaking’ floorboards – underfloor insulation will help muffle the sound of foot traffic and give your floorboards a more solid feel.

  • Your home is an older style property showing signs of damaged pre existing insulation and no longer effective.

  • If your flooring is damaged and you’re considering replacement – this is a good time to also check its insulation levels.

If you’re unsure if underfloor Insulation is right for your property or would like to discuss the various options with our team of professionals, please don’t hesitate to contact us to see how we can help you reduce your energy bills.

By installing better insulation at floor level, you will benefit in more ways than one. We’ve listed some of the key benefits below:

  • Increased energy savings and therefore lower bills!

  • Improved indoor comfort by eliminating draughts and unwanted air infiltration

  • Deter unwanted pests and nesting

  • Improve the efficiency of your underfloor heating system

  • Increased EPC rating

  • Longevity as well as increased structural support

  • Add value to your home

Overall it’s a no braining and our view is, that having underfloor insulation installed is worth its weight in gold and a worthwhile investment that will significantly reduce your energy bills and increase your indoor home comfort.

It’s worth us highlighting that for solid floors these are usually insulated at construction stage and more difficult to modify afterwards. Here at Sealsixty we can offer two different retrofit energy saving measures for properties with suspended underfloor, we’ve provided a brief overview on each of these options below for your review.

Underfloor insulation solutions

Spray foam insulation

If there is enough crawl space beneath your home to allow for application then spray foam insulation is our first recommendation for providing high thermal performance through increased airtightness. It’s applied with speed and ease direct to the underside of the floor and comes with a 25 year product warranty. It will also last the lifetime of the buildings structure!

Smart-ventilation

Smart Sub Floor Ventilation

Replace any standard air bricks with a smart ventilation system that detects moisture and humidity levels, allowing it to only open and closes as required. Eliminating unnecessary air intrusion whilst increasing your EPC between 2-4 SAP points! This is a great, affordable solution for properties with hard to access underfloors or as a secondary measure alongside other insulation.
