Why Choose Us for Internal Wall Insulation in Ferndale?

Why Choose Internal Wall Insulation for Your Home

Many traditional properties in Blaenau Gwent, including Victorian terraces and non-traditional builds, feature solid walls that lose heat rapidly. Internal wall insulation is the ideal choice when you cannot alter the exterior of your building due to planning restrictions or architectural character. By installing high-performance insulation boards and vapour barriers, we significantly reduce heat loss and eliminate thermal bridging. This not only keeps your rooms warmer during the winter but also helps prevent the black mould and damp issues often caused by cold wall surfaces.

Our PAS 2035 Compliant Retrofit Process

Quality is at the heart of everything we do. As a PAS 2030 accredited contractor, we follow rigorous PAS 2035 whole-house retrofit standards to ensure every installation delivers optimal performance. Our team coordinates the entire process, from the initial assessment to the final handover. We focus on moisture management and airtightness, protecting the structural integrity of your home while creating a much more energy-efficient living space. You can trust our experienced team to manage every technical detail of your energy upgrade.

Seamless Finishing with Global Plastering

We understand that insulation work is only half the battle; the final aesthetic of your home matters just as much. This is why we partner with our sister company, Global Plastering, to provide a truly comprehensive end-to-end service. Once our insulation boards are installed, our skilled plasterers deliver a professional, smooth finish ready for decoration. By managing the insulation and plastering under one umbrella, we ensure a faster, more efficient project that minimises disruption to your daily life in Abertyleri or Abertillery.

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.
