Why Choose Us for Internal Wall Insulation in Ferndale?

How Our Internal Wall Insulation Process Works

Our approach to IWI is rooted in precision and long-term performance. We begin with a thorough survey of your property to identify areas where thermal bridging is occurring. As a PAS 2030 accredited company, we manage the entire process in accordance with PAS 2035 retrofit standards. This ensures your home is assessed properly to avoid issues like condensation or damp, which can occur if insulation is installed incorrectly. Once the insulation boards are professionally fitted, we work closely with our sister company, Global Plastering, to provide a high-quality plaster finish. This end-to-end service ensures that once we finish, your walls are perfectly smooth and ready for decoration.

Could Internal Wall Insulation Improve Your Home EPC Rating

Improving your home energy efficiency is no longer just about comfort; it is a necessity for meeting modern environmental standards. For landlords in Aberpennar and Mountain Ash, ensuring your rental properties meet MEES compliance is vital. Installing internal wall insulation is one of the most effective ways to significantly boost your EPC rating. By targeting the thermal envelope of your building, we help you avoid potential fines and ensure your property remains attractive to future tenants. Whether you own a Victorian terrace or a more modern construction, our team provides the technical expertise to deliver compliant, long-lasting results.

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.
