Why Choose Us for Internal Wall Insulation in Ferndale?

How Internal Wall Insulation Stops Heat Loss

Internal wall insulation involves applying high-performance insulation boards to the inner face of your external walls. This process acts as a thermal barrier, drastically reducing heat loss and solving the problem of thermal bridging where cold enters the structure. For period properties like Victorian or Edwardian houses, this method is often the most effective way to improve thermal performance without altering the external appearance of the building. Our team ensures that every stage of the installation process is handled with precision to deliver a lasting, high-quality finish.

Addressing Damp and Improving Your EPC Rating

One of the most significant advantages of choosing our insulation services is the prevention of black mould and damp. By warming up the internal surface of your walls, we remove the cold conditions that lead to condensation. If you are a landlord in Neath needing to meet MEES compliance or a homeowner looking to improve your EPC rating, our retrofit services provide the perfect solution. We focus on meeting strict UK building regulations and Part L requirements, ensuring your property is future-proofed against rising energy costs.

A Seamless Finish with Global Plastering

We understand that insulation is only part of the project. To provide a complete end-to-end service, we work alongside our sister company, Global Plastering. This ensures that once the insulation boards are installed, your walls receive a professional, high-quality plaster finish, leaving your rooms ready for decoration. By combining thermal expertise with expert plastering, we save you the time and stress of coordinating multiple contractors. Our team takes pride in leaving your home neat, tidy, and significantly warmer.

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.
