Why Choose Us for Internal Wall Insulation in Ferndale?

Why choose internal wall insulation for your home?

Many properties across the Vale of Glamorgan feature solid wall construction, which is notorious for poor thermal performance. Internal wall insulation acts as a thermal barrier, preventing heat from escaping through your walls. This process is particularly beneficial for properties where external wall insulation is not permitted or feasible due to planning restrictions or architectural features. Beyond keeping you warmer in winter, IWI is a key strategy for reducing damp and condensation issues caused by cold wall surfaces. It is an ideal solution for those looking to improve their EPC rating and meet modern energy standards.

Our professional installation and retrofit process

As PAS 2030 accredited specialists, we follow a rigorous, quality-controlled process for every project. Our team performs a detailed survey to assess the thermal requirements of your home and ensures all work complies with the latest PAS 2035 retrofit standards. Installation involves carefully applying insulation boards to the interior walls, which are then finished to a high standard. We pride ourselves on a seamless end-to-end service, where our sister company, Global Plastering, handles all final plastering works to ensure your walls look perfect. This integrated approach means you receive professional insulation and a pristine finish in one go.

What is the impact on your EPC rating?

Improving the energy efficiency of your property is more important than ever, especially for landlords needing to meet Minimum Energy Efficiency Standards (MEES). By installing internal wall insulation, you can significantly enhance your property's EPC rating, making it more attractive to tenants and more cost-effective to heat. Our team provides the documentation and expertise required to ensure your energy improvements are properly recorded and certified. We are dedicated to delivering sustainable, long-term solutions that provide genuine value to your investment.

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.
