Expert Solid Wall Insulation in Llanymddyfri and Llandovery

If your home in Llanymddyfri or Llandovery feels impossible to keep warm, solid wall construction is often the culprit. Many older properties in Carmarthenshire lack the cavity space found in modern homes, leading to significant heat loss through uninsulated walls. At Global Energy Insulation, we specialise in thermal upgrades that transform cold, draughty houses into efficient, comfortable homes. Whether you own a traditional Victorian terrace or a non-traditional build, our PAS 2030 accredited team is here to help you reduce your energy bills and improve your living environment.

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.

Improving Energy Efficiency with EWI and IWI

We offer two primary solutions for your home: External Wall Insulation (EWI) and Internal Wall Insulation (IWI). External wall insulation involves fixing thermal boards to the outside of your property, which are then finished with a high-quality render to provide a fresh, modern aesthetic while wrapping your home in a protective, insulated layer. If your property has period features that must be preserved or is located in a conservation area, our internal wall insulation provides an effective alternative by adding a thermal lining to your interior walls. Both methods are highly effective at eliminating cold spots and preventing the damp and mould issues often caused by thermal bridging.

How we meet PAS 2035 and EPC requirements

Energy efficiency is no longer just about comfort; it is about compliance and long-term value. For landlords in Carmarthenshire needing to meet MEES regulations, or homeowners looking to improve their EPC rating, our retrofitting services are essential. We operate as a PAS 2035 compliant specialist, meaning every project we undertake is managed with the highest standards of technical rigour. From the initial retrofit assessment to the final handover, we ensure your home meets all current UK building regulations, providing you with peace of mind and official documentation for your property improvements.

Can we manage the full installation and internal finish?

Yes, we provide a complete, end-to-end service for all our clients in Llanymddyfri and the surrounding Carmarthenshire area. When you choose us for your insulation needs, you benefit from our partnership with our sister company, Global Plastering.

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.
