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 Home Needs Solid Wall Insulation

Solid walls act like a heat sink, drawing warmth out of your living space and pushing it into the outside air. By installing external wall insulation or internal wall insulation, you create a thermal barrier that stops this heat loss at the source. This is a vital step for any homeowner in North Somerset looking to reduce energy consumption. Beyond lower bills, you will notice an immediate improvement in your home's thermal comfort, making cold drafts and freezing wall surfaces a thing of the past. Our tailored approach ensures we identify the perfect insulation method to suit your property’s unique construction and aesthetic.

How We Achieve PAS 2035 Compliance

Navigating the complexities of building regulations and energy efficiency standards can be daunting. As a PAS 2030 accredited company, we manage the entire process from start to finish. We work closely with PAS 2035 retrofit coordinators to ensure that every installation is technically sound, safe, and fully compliant with current UK building regulations. For landlords in the Portishead area, this is particularly important for meeting MEES compliance requirements and boosting your EPC rating. We provide professional documentation that gives you complete confidence in the long-term performance and legality of your home improvements.

The Benefits of Our End-to-End Service

We believe that home improvement should be stress-free and comprehensive. While Global Energy Insulation handles the high-performance thermal layers and external finishes, our sister company, Global Plastering, steps in to provide expert internal finishes if you choose internal wall insulation. This partnership ensures that your home is not only thermally efficient but also beautifully finished on the inside. By choosing us, you receive a professional service backed by SWIGA insurance-backed guarantees, ensuring your investment is protected for years to come.

Common Questions About Solid Wall Insulation

Many customers ask whether external wall insulation will change the look of their home. Our range of high-quality silicone and render finishes can actually modernise the appearance of your property while protecting it from the elements. Another common question relates to the impact on floor space; while internal insulation does take up a small amount of room, our team uses the most effective, space-efficient materials available. Finally, we are often asked about the installation timeframe, which varies based on the size of your property, but our experienced team works efficiently to minimise disruption to your daily life in Portishead.

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.
