If you live in a traditional home in Y Fenni or Abergavenny, you are likely all too familiar with the struggle of keeping your living space warm during the winter months. Many period properties and solid wall homes throughout Monmouthshire were built without modern insulation standards, leading to significant heat loss through the walls. Global Energy Insulation provides professional solid wall insulation solutions, helping homeowners and landlords across the region reduce their heating bills and improve their home EPC ratings. Whether you are in a Victorian terrace or a more modern solid wall build, we deliver the thermal efficiency improvements your property needs to stay comfortable all year round.

Why Choose Our Solid Wall Insulation Services in Ferndale?

Whether you require External Wall Insulation (EWI) or Internal Wall Insulation (IWI), Global Energy Insulation delivers SWIGA-backed heat loss solutions to lower your high energy bills and improve your property's EPC rating across South Wales and the South West. Working seamlessly alongside our sister company, Global Plastering, we guarantee a flawless, fully compliant, end-to-end retrofit finish.

Why Solid Wall Insulation is Essential for Your Home

Uninsulated solid walls can account for up to 45% of total heat loss in the average property. By installing either External Wall Insulation or Internal Wall Insulation, you create a high-performance thermal barrier that stops heat from escaping. This not only makes your home significantly warmer but also eliminates common problems like cold spots, damp patches, and condensation buildup. Improving the energy efficiency of your property is one of the most effective ways to lower your monthly energy bills and protect your home against rising energy costs, ensuring your property meets modern standards for long-term comfort.

Our Comprehensive PAS 2035 Retrofit and Compliance Standards

We pride ourselves on being fully PAS 2030 accredited and PAS 2035 compliant. For landlords and homeowners in Monmouthshire, navigating the complex landscape of MEES regulations and EPC requirements can be daunting. Our team handles the full process, including PAS 2035 retrofit coordination and assessment. This ensures that every project we undertake adheres to the highest safety and performance standards in the UK building industry. By choosing a specialist, you are ensuring your property receives a holistic energy efficiency upgrade that is both compliant with local regulations and built to last.

The Benefits of Our End-to-End Installation Process

Our service is designed to be as stress-free as possible for the property owner. When you work with us, you benefit from our partnership with our sister company, Global Plastering. This allows us to provide a seamless transition from the insulation installation to the final high-quality internal plastering finish. Furthermore, all our solid wall insulation installations are backed by the Solid Wall Insulation Guarantee Agency (SWIGA). This provides you with an Insurance Backed Guarantee, offering long-term protection and peace of mind for your investment. We are also CHAS accredited and hold a valid Waste Carriers Licence, so you know your property is in professional, safe, and regulated hands.

Common Questions About Solid Wall Insulation

Many clients ask if their property type is suitable for insulation. Whether you live in an older stone-built home or a non-traditional concrete build, we have the technical expertise to assess your specific requirements. Another frequent question relates to the impact on the building's exterior. Our EWI systems can be finished with a wide range of aesthetic rendering options, such as silicone or K Rend, which can actually improve the appearance of your home while protecting the fabric of the building. Regarding timeframes and costs, every project is unique, which is why we offer bespoke assessments to provide accurate, transparent pricing for your specific needs.

Solid Wall Insulation FAQs

Frequently Asked Questions

Have questions about stopping heat loss, improving your EPC rating, or choosing between EWI and IWI? Find answers about our PAS 2035 accredited solid wall insulation services across South Wales and South West England, South Wales, and the South West.

How long does it take to install external wall insulation?

+

For a standard semi-detached house in Ferndale, the process usually takes between two to three weeks, depending on the weather. This includes the preparation, fixing the insulation boards, and applying the final render finish.

Will I lose much space with internal wall insulation?

+

We use high-performance materials that provide maximum warmth with minimum thickness. While you will lose a few centimetres of room width, the trade-off is a significantly warmer, more comfortable living space that is much cheaper to heat.

Do I need planning permission for EWI?

+

In many cases, EWI falls under "permitted development." However, if you live in a conservation area or a listed building, or if the insulation significantly changes the look of the street, permission may be required. We can help you understand the requirements for your specific location in Rhondda Cynon Taf or beyond.

Can solid wall insulation stop damp?

+

Yes, it is highly effective at stopping penetrating damp and condensation. By keeping the walls warm, moisture in the air no longer settles on them as water droplets, which prevents the growth of black mould.
