Why Is Your Floor Responsible for High Energy Bills

It is a common misconception that heat only escapes through walls and roofs. In reality, a drafty floor is a major source of thermal bridging, particularly in Victorian terraces and older semi-detached homes across Merthyr Tydfil. Cold air enters through gaps in floorboards and joists, cooling the room from the bottom up. Our professional insulation service creates a thermal barrier that blocks these drafts, keeps your living space at a constant temperature, and prevents the damp issues often caused by poor ventilation. If you are a landlord, this is a vital step toward meeting current MEES regulations and boosting your property's EPC rating.

Our PAS 2035 Retrofit Process for Local Homes

Quality assurance is at the heart of what we do at Global Energy Insulation. As PAS 2030 accredited specialists, we strictly follow PAS 2035 whole-house retrofit standards to ensure that your insulation is installed safely and effectively. Our process begins with a detailed assessment of your property type, whether it is a traditional stone cottage or a post-war dwelling. We then carefully install insulation materials between joists for suspended timber floors, ensuring all work is done to the highest industry standard. We take care of every detail, meaning you benefit from a professional, long-lasting solution that avoids the common pitfalls of DIY attempts.

Expert Finishing and Seamless Home Improvements

We pride ourselves on offering a complete service that goes beyond simple insulation. While we focus on thermal performance, we understand that you want your home to look its best once the work is finished. Through our sister company, Global Plastering, we provide expert internal finishing and floor preparation, ensuring a smooth and tidy result every time. This collaboration allows us to deliver an end-to-end service, meaning you do not need to hire multiple contractors to finish the job. From insulation to plastering, our team provides a clean, professional finish across the entire South Wales region.

Local Expertise and Trustworthy Accreditation

Choosing a local contractor means choosing a team that knows the unique building challenges faced by Merthyr Tudful homeowners. We are fully insured, hold a valid Waste Carriers Licence, and maintain CHAS accreditation to ensure your peace of mind. Every project we undertake is backed by the Solid Wall Insulation Guarantee Agency (SWIGA), providing you with a robust Insurance Backed Guarantee for your investment. We are proud to serve the wider South Wales and South West area, helping communities improve their home energy efficiency and overall living standards.

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.
