Why Choose Us for Internal Wall Insulation in Ferndale?

How Internal Wall Insulation Stops Heat Loss

Our insulation process involves fixing premium PIR insulation boards to the interior of your external walls, followed by a high-quality vapour control layer to manage moisture. This process effectively breaks the cycle of thermal bridging, where heat escapes through solid brick or stone walls. By adding this thermal barrier, you can reduce heat loss by up to 35 percent. Once the insulation is installed, our sister company, Global Plastering, provides a seamless professional finish, leaving your walls ready for decoration as if we were never there.

Why Choose IWI for Solid Wall Properties

Many homes in Llanwrtyd Wells feature solid wall construction, which is notoriously poor at retaining heat compared to modern cavity walls. IWI is the ideal solution for these buildings, especially where external wall insulation may not be suitable due to planning restrictions in conservation areas or the need to preserve an original aesthetic. Our team is highly experienced in retrofitting these properties, ensuring that you achieve a better EPC rating and a more comfortable home without compromising your property's character.

Meeting EPC Standards and PAS 2035 Compliance

For landlords managing HMOs or rental properties in Powys, meeting Minimum Energy Efficiency Standards (MEES) is essential. Our team simplifies this process by acting as your PAS 2035 retrofit coordinator and assessor. We handle the technical compliance and documentation required to improve your property's energy performance certificate (EPC). Whether you are preparing for a new tenancy or looking to lower your own monthly fuel costs, we ensure the installation meets all rigorous national standards.

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.
