Why Choose Us for Internal Wall Insulation in Ferndale?

Why Choose Internal Wall Insulation for Your Home

Many older properties across Brynmawr, including traditional Victorian terraces and solid wall houses, suffer from significant heat loss. Internal wall insulation acts as a thermal barrier, effectively stopping heat from escaping through your walls. This process not only reduces your energy bills but also plays a vital role in thermal bridging solutions, which prevents cold spots and helps to eliminate stubborn black mould and condensation issues. By choosing this method, you can significantly improve your home energy efficiency without altering the exterior aesthetic of your building.

Our Professional PAS 2035 Compliant Process

At Global Energy Insulation, we pride ourselves on a rigorous, compliant approach to every project. As a PAS 2035 compliant firm, we perform a thorough retrofit assessment to identify the most effective strategy for your property. Our installation involves fixing high-performance insulation boards to your internal walls, followed by the installation of a high-quality vapour control layer. This ensures that your walls are protected from moisture ingress while maintaining a healthy, breathable environment inside your home.

A Seamless Finish with Global Plastering

We understand that insulation is only half the battle; the final look of your interior matters just as much. By working in close partnership with our sister company, Global Plastering, we provide a complete end-to-end service. Once your insulation is securely fitted, our expert plastering team will ensure your walls are finished to a high standard, ready for painting or decorating. This integrated approach ensures that you get a thermally efficient home that looks pristine, saving you the hassle of coordinating multiple contractors.

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.
