How Underfloor Insulation Stops Heat Loss

Heat loss through uninsulated ground floors can account for a significant portion of your property’s total heat loss. Our installation process focuses on sealing off voids and gaps to eliminate cold draughts that creep up through floorboards. By installing high-performance insulation, we prevent thermal bridging and create a consistent, comfortable temperature throughout your home. This process is essential for older properties in Powys that rely on traditional suspended timber floors.

Improving Your EPC Rating and Property Value

Many properties in Ystradgynlais require energy efficiency upgrades to meet modern standards. Our underfloor insulation services are a highly effective way to improve your EPC rating, which is particularly vital for landlords needing to meet MEES compliance. By reducing the energy required to heat your home, we help you lower your carbon footprint and monthly utility costs simultaneously. Investing in professional insulation is one of the smartest ways to add long-term value to your property.

Is Your Property Suitable for Retrofit Insulation?

Whether you live in a period home or a modern build, we assess the suitability of your floor type to ensure the right materials are used. As specialists in PAS 2035 retrofit standards, we handle everything from initial assessments to the final installation. We understand the unique building requirements in the Powys area and ensure full compliance with UK building regulations. If your floor requires internal restoration or finishing works, our sister company, Global Plastering, is on hand to provide a complete, end-to-end service.

Underfloor Insulation FAQs

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited underfloor insulation, draught-proofing, and heat loss reduction services across South Wales and South West England and South Wales.

How much mess does the installation create?

+

If you have a crawl space under your home, we can often do the work without lifting your floorboards, meaning there is very little disruption to your home. If we do need to lift boards, our team works methodically to make sure the process is clean and tidy.

Will underfloor insulation cause my floors to rot?

+

No, provided it is installed correctly. We make sure that your sub-floor ventilation (air bricks) stays clear. This keeps the air moving and protects your timber joists from moisture build-up. This is why using a PAS 2030 accredited installer is so important.

How long does it take to pay for itself?

+

With energy prices remaining high, the "payback period" for floor insulation has shortened significantly. Most homeowners find that the savings on their heating bills cover the cost of the installation within a few years, all while enjoying a much more comfortable home.

Can you insulate solid concrete floors?

+

Yes, but the process is different. For solid floors, we usually lay high-density insulation boards on top of the concrete, followed by a new floor covering. This can raise the floor height slightly, so we will discuss the best options for your specific property during our site visit.
