Why Choose Us for Internal Wall Insulation in Ferndale?

How Internal Wall Insulation Transforms Your Property

Internal wall insulation is the ideal choice for properties where external wall insulation is not viable, such as listed buildings or homes with specific planning constraints. Our process begins with a detailed assessment to ensure your home is suitable for treatment. We then install premium PIR insulation boards along with a high-quality vapour control layer to manage moisture and prevent condensation effectively. This creates a thermal barrier that stops cold air from penetrating your walls, keeping your home warm in the winter and cool in the summer. Once the boards are installed, our sister company, Global Plastering, provides a professional final skim to ensure a flawless, ready-to-decorate finish.

Meeting PAS 2035 Standards and EPC Requirements

Navigating energy efficiency standards can be complex, but we make it straightforward. As PAS 2030 accredited specialists, we work to PAS 2035 retrofit standards to ensure your home meets all necessary UK building regulations. For landlords in Aberhonddu and Brecon, improving your EPC rating is essential for MEES compliance. Our team handles everything from the initial PAS 2035 retrofit assessment to the final handover, ensuring your property is fully compliant with current energy standards. By choosing our service, you are investing in a verified, high-quality retrofit that adds long-term value to your building.

Our expertise is backed by full CHAS accreditation and SWIGA-backed insurance guarantees, giving you total peace of mind throughout the project.

We are fully insured and hold a valid waste carriers licence, ensuring every aspect of your project is handled with professionalism and care.

Frequently Asked Questions About Internal Insulation

A common question is how much space is lost during the process. We use thin, high-performance insulation materials to maximise your internal floor area while still delivering excellent thermal results. Another concern is condensation; by installing a proper vapour control layer, we actively help reduce damp issues often found in older solid wall properties. Regarding the timeline, our efficient team works quickly to minimise disruption to your daily life. If you have specific questions about your building type or current energy efficiency, we are happy to provide clear, expert advice tailored to 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.
