Why Choose Us for Internal Wall Insulation in Ferndale?

Why choose internal wall insulation for your solid wall property?

Many older properties in the Caerllion and Caerleon area feature solid walls that lack effective thermal protection. Without insulation, these walls act as a direct bridge for heat to escape, leaving rooms feeling damp and uncomfortable. Internal wall insulation involves applying high-performance thermal boards to the interior surface of your external walls. This process is particularly advantageous for listed buildings or homes within conservation areas where changing the external facade is not permitted. By improving your EPC rating, you not only enjoy a warmer home but also increase its market value while ensuring you meet the latest MEES regulations for rental properties.

Our end-to-end PAS 2035 retrofit and installation process

At Global Energy Insulation, we pride ourselves on a comprehensive approach to home efficiency. As PAS 2030 compliant specialists, we follow strict PAS 2035 standards to ensure your project is completed safely and to the highest regulatory requirements. Our process begins with a detailed retrofit assessment to determine the best solution for your property type, whether it is a terrace, bungalow, or commercial office. Once the insulation boards are professionally installed, our sister company, Global Plastering, provides a high-quality finish, ensuring your walls are smooth, perfectly decorated, and ready for use. You benefit from a seamless, one-stop service managed by our expert local team.

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.
