Why Choose Us for Internal Wall Insulation in Ferndale?

Why Internal Wall Insulation is the Right Choice

Internal wall insulation is a highly effective method for improving the energy efficiency of homes where external wall insulation may not be suitable, such as properties with period features or those within conservation areas. By applying insulation boards to the inner face of your external walls, we create a thermal barrier that traps warmth inside your rooms. This process is essential for reducing thermal bridging, which is often the primary cause of cold spots and condensation on walls. Once installed, these measures can significantly boost your home energy efficiency and help you achieve a better EPC rating, which is increasingly vital for landlords meeting MEES compliance.

Our Seamless Process from Installation to Finish

We pride ourselves on providing a complete end-to-end service for homeowners in Pontypridd. As a PAS 2030 accredited specialist, our retrofit coordination ensures that every stage of the insulation process adheres to strict building regulations and industry standards. Because we are a PAS 2035 compliant company, we manage the technical assessment and installation with precision. Following the installation of the insulation, our sister company, Global Plastering, steps in to provide professional skimming and finishing. This partnership means your walls are not only thermally efficient but are also left with a perfect, smooth surface ready for decoration.

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.
