Expert Solid Wall Insulation Services in Treorci and Treorchy

Global Energy Insulation is your trusted specialist for solid wall insulation in Rhondda Cynon Taf and the wider South Wales area. Many period properties across Treorci and Treorchy are constructed with solid brick or stone walls, which lack a cavity and act as a constant source of heat loss. This often leads to cold interiors and soaring energy bills. Our expert team provides tailored External Wall Insulation (EWI) and Internal Wall Insulation (IWI) solutions to transform your home into a warmer, more energy-efficient space.

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 Your Property Needs Thermal Efficiency Upgrades

If you live in a traditional terrace or older home in the Rhondda Valley, you are likely feeling the impact of poor thermal retention. Without adequate insulation, your walls act like a heat sink, drawing warmth out of your living areas. Improving your insulation not only stops this thermal bridging but also creates a robust barrier against moisture and black mould. By investing in our professional services, you can significantly improve your home energy efficiency and boost your EPC rating, which is essential for both comfort and property value.

What are the benefits of choosing Global Energy Insulation?

We take a whole-house approach, adhering strictly to PAS 2035 retrofit standards to ensure every installation is safe and effective. As a PAS 2030 accredited company, we guarantee quality and regulatory compliance on every project. Because we are backed by SWIGA, you also benefit from insurance-backed guarantees for extra peace of mind. Furthermore, our sister company, Global Plastering, works alongside us to provide expert internal finishing, meaning you receive a complete, end-to-end service from the first survey to the final coat of plaster.

How our retrofit process ensures long-term home performance

Our process begins with a thorough assessment by our qualified PAS 2035 retrofit team to determine the most suitable insulation method for your specific building type. Whether it is EWI to refresh your exterior with high-performance silicone render or IWI to maintain the character of your facade, we handle every detail including local planning permissions. We work efficiently to minimise disruption while ensuring that all works meet current building regulations and energy efficiency standards for the UK.

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.
