Why Choose Us for Internal Wall Insulation in Ferndale?

How our thermal retrofit process works

We begin every project with a professional assessment to ensure your home is suitable for internal insulation, adhering strictly to PAS 2035 retrofit standards. Our experienced team installs high-quality insulation materials directly to the interior of your external walls, effectively creating a thermal envelope that keeps warmth exactly where it belongs. Once the boards are fitted, our sister company, Global Plastering, steps in to provide a professional, seamless finish, ensuring your walls are ready for decoration immediately. This end-to-end service guarantees a stress-free experience from the initial survey to the final skim.

Why choose IWI for your Bargoed property?

Upgrading your home with internal wall insulation offers numerous advantages beyond just feeling warmer. It is one of the most effective solutions for solid-wall properties, such as Victorian terraces or traditional stone-built houses, which often suffer from thermal bridging. By installing IWI, you can prevent condensation and damp issues, which are common causes of black mould in older dwellings. Furthermore, this upgrade is a proven way to improve your home energy efficiency and boost your EPC rating, helping landlords meet current MEES compliance requirements and homeowners increase their property value.

Meeting local building regulations and standards

Navigating building regulations can be daunting, but our team at Global Energy Insulation makes compliance simple. As a PAS 2030 accredited contractor, we ensure every installation meets the rigorous requirements set out by PAS 2035. Whether your property is a traditional terrace or a unique build in the heart of Bargoed, we account for ventilation, fire safety, and structural integrity during every stage of the process. We are fully insured, hold a Waste Carriers Licence, and provide SWIGA-backed guarantees for your complete peace of mind, ensuring your investment is protected by industry-leading standards.

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.
