One of the common concerns regarding internal wall insulation is the impact on your home's interior appearance. We make this process seamless through our unique partnership with our sister company, Global Plastering.

This end-to-end service ensures you receive a flawless, ready-to-decorate wall while benefiting from significantly improved insulation. Whether you are living in a Victorian terrace or a modern flat, we ensure your living space is left clean, tidy, and aesthetically pleasing.

How Internal Wall Insulation Stops Damp and Heat Loss

Many residents in Abercynon deal with the dual problems of high heating costs and persistent condensation or black mould. Solid walls act as a thermal bridge, allowing cold from the outside to permeate your rooms, which lowers internal surface temperatures and encourages moisture buildup. Our high-performance IWI systems create a robust thermal barrier, keeping the heat inside where it belongs. This not only makes your home feel warmer during the winter months but also prevents the surface conditions that allow damp to thrive, leading to a much healthier living environment for you and your family.

Navigating the regulations for energy-efficiency upgrades can feel daunting, but we are here to simplify the process. Whether you are aiming for MEES compliance for a rental property or looking to access support through the ECO4 scheme, our team ensures every installation meets current building regulations. We have extensive experience working on various local building types, including traditional stone-built houses and non-traditional construction, ensuring that the moisture management and ventilation requirements of your specific property are always respected. Our goal is to make the journey toward a more energy-efficient home as straightforward as possible.

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.
