Why Choose Us for Internal Wall Insulation in Ferndale?

Why choose IWI for your Somerset property?

Internal wall insulation is the ideal solution for Victorian, Edwardian, and non-traditional builds where external wall insulation is restricted by planning permissions or local conservation area rules. Many older homes in Somerset suffer from significant heat loss through solid masonry walls, which often leads to condensation and black mould issues. Our IWI systems act as a thermal barrier, locking warmth inside your rooms and lowering your monthly heating bills. This process is essential for landlords aiming to meet MEES compliance standards and improve their property's EPC rating, ensuring your investment remains both comfortable and legally compliant.

How our professional IWI installation works

Our process is rooted in technical precision and compliance with PAS 2035 retrofit standards. We begin with a thorough assessment to identify the specific thermal needs of your building. Our installers then fit high-performance insulation boards to the interior of your external-facing walls. Following the installation, our sister company, Global Plastering, steps in to provide a seamless, high-quality finish. By combining insulation expertise with professional plastering, we offer a complete, end-to-end service that leaves your home ready for decoration immediately.

Ensuring quality through industry-leading accreditations

We take the complexity out of home energy upgrades by managing the entire process for you. As a PAS 2030 accredited company, we have the technical expertise to handle your project from initial retrofit coordination to final sign-off. Every installation we perform is backed by SWIGA, providing you with an Insurance Backed Guarantee for long-term peace of mind. We hold a valid Waste Carriers Licence and comprehensive public liability insurance, ensuring that every project in Minehead is carried out with professionalism, safety, and regulatory compliance at the forefront.

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.
