Why Choose Us for Internal Wall Insulation in Ferndale?

Why choose Internal Wall Insulation for your home

Internal Wall Insulation is an ideal choice for Victorian terraces, period properties, and solid-wall homes across Carmarthenshire where you wish to preserve the external character of the building. By installing high-quality insulation boards to the interior, we effectively tackle thermal bridging and cold spots. This process not only makes your home feel much cosier during the colder months but also helps to lower your monthly heating costs. Furthermore, it is a proven method to reduce condensation and prevent the formation of black mould, ensuring a healthier indoor environment for your family.

We understand that insulation is only one part of the journey. To ensure your home looks as good as it performs, we work in seamless partnership with our sister company, Global Plastering.

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.
