Expert Internal Wall Insulation in Abercarn

If you are struggling with a cold house or sky-high heating bills in Abercarn, your walls might be to blame. Many older properties in Caerphilly, particularly Victorian terraces and traditional solid-wall homes, lose a vast amount of heat directly through the brickwork. Global Energy Insulation provides professional internal wall insulation (IWI) to help homeowners across the region improve their energy efficiency and comfort. By installing high-performance thermal boarding systems, we create a warmer, more stable indoor environment that helps you slash your energy usage.

Why Choose Us for Internal Wall Insulation in Ferndale?

How Our IWI Process Works for Your Home

Our process begins with a thorough property assessment to ensure the system is suitable for your specific wall type. As PAS 2030 accredited installers, we follow strict industry guidelines to ensure the insulation is applied safely and effectively. We carefully install rigid thermal boards or stud-wall systems to your interior walls, significantly reducing heat loss. Because we operate in partnership with our sister company, Global Plastering, we provide a complete end-to-end service. This means your walls are not only insulated but professionally plastered and finished to a high standard, ready for decoration immediately.

Why Choose Internal Insulation for Your Property

Choosing IWI is a highly effective way to transform the thermal performance of your home without altering the external appearance, which is particularly beneficial for listed buildings or homes in conservation areas. Beyond drastically reducing your heating bills, our insulation systems help with damp prevention by eliminating cold spots where condensation often forms. Improving your home energy efficiency also plays a vital role in raising your EPC rating, helping landlords meet current MEES compliance requirements and increasing the long-term value of your property.

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.
