Why Choose Us for Internal Wall Insulation in Ferndale?

Why choose internal wall insulation for your property?

Many older homes across Powys suffer from significant thermal bridging, leading to persistent cold spots and the risk of condensation or black mould. Internal wall insulation is a highly effective solution that involves fitting rigid insulation boards to the interior face of your external walls. This process acts as a thermal barrier, locking heat inside your rooms rather than letting it escape through the masonry. Beyond immediate energy savings, this upgrade helps you improve your home energy efficiency and makes a meaningful impact on your EPC rating, which is essential for landlords navigating current MEES regulations.

At Global Energy Insulation, we pride ourselves on a seamless, professional approach to home retrofitting. As PAS 2030 accredited specialists, we work closely with PAS 2035 retrofit coordinators to ensure every installation meets the highest UK building regulations.

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.
