Why Choose Us for Internal Wall Insulation in Ferndale?

Why Choose Internal Wall Insulation for Your Porthcawl Home

Many older properties in South Wales suffer from poor thermal performance, often leading to condensation, damp issues, and exorbitant energy costs. By applying high-quality insulation to the interior face of your external walls, we stop heat from escaping through the structure. This thermal barrier is particularly effective for solid-wall homes, including Victorian terraces or mid-century houses. Improving your home's thermal performance not only creates a more comfortable environment but also helps you improve your property's EPC rating, which is increasingly important for homeowners and landlords alike.

Our Professional Installation Process and PAS 2035 Standards

At Global Energy Insulation, we pride ourselves on a meticulous approach to every project. As a PAS 2030 accredited company, we follow stringent PAS 2035 retrofit standards to ensure your home is treated as a whole system. Our qualified team handles everything from the initial technical survey to the final installation. Because we operate in partnership with our sister company, Global Plastering, we provide a true end-to-end service. Once the insulation boards are professionally fitted, we provide seamless internal finishing, ensuring your walls are ready for decoration so you can enjoy a warmer home with minimal disruption.

How Do We Ensure Quality and Compliance?

We understand that investing in your home requires trust, which is why we prioritise transparency and high standards. Every project we undertake in Porthcawl is backed by SWIGA (Solid Wall Insulation Guarantee Agency) for your peace of mind. As a CHAS accredited contractor, we hold full public liability insurance and a valid waste carriers licence. Whether you are dealing with cold wall treatment, thermal bridging solutions, or a full-scale renovation, our expert team provides the knowledge and experience required to navigate building regulations and retrofit requirements effortlessly.

FAQ

Frequently Asked Questions

Answers to common questions about our internal wall insulation and PAS 2035 retrofit services in South Wales and South West England and across South Wales.

How much space will I lose with Internal Wall Insulation?

+

This is a common concern for homeowners in smaller terraced houses. Modern high-performance insulation boards are incredibly efficient, meaning we can achieve great results with boards as thin as 50mm to 100mm. While you will lose a tiny bit of floor space, the trade-off is a room that is actually usable and warm all year round.

Does IWI cause damp or mould?

+

If installed incorrectly by an unaccredited builder, IWI can cause issues. However, because we follow PAS 2035 standards, we assess the ventilation of your home as part of the process. We use vapour barriers and ensure proper airflow so that moisture doesn't get trapped. When done right, IWI actually reduces the risk of surface mould by getting rid of cold spots on your walls.

How long does it take to insulate a room?

+

A typical room can usually be insulated and boarded within a couple of days. The plastering and drying time will add a bit more to the schedule. Because we use our own sister company, Global Plastering, we can move from insulation to finishing much faster than companies that have to wait for external subcontractors to become available.

Is there funding available for IWI in Rhondda Cynon Taf?

+

There are often various government grants available, such as ECO4 or the Great British Insulation Scheme, depending on your circumstances and your property's current EPC rating. As PAS 2030 installers, we can often help you navigate these options. Even if you aren't eligible for a grant, the long-term savings on your energy bills make IWI a very smart investment.
