Why Choose Us for Internal Wall Insulation in Ferndale?

How Our Internal Wall Insulation Process Works

Our team follows a rigorous PAS 2035 retrofit approach to ensure your insulation is installed correctly the first time. We begin by assessing your property to identify the best thermal boarding or stud-wall system for your specific wall type, whether you live in a traditional Victorian terrace or a modern structure. Once the materials are installed to meet strict thermal standards, we ensure that your walls are properly sealed to prevent thermal bridging and cold spots. The process is designed to be as non-disruptive as possible, focusing on high-quality delivery and long-term performance.

Why Internal Wall Insulation is Essential for Your Home

Upgrading your home with internal wall insulation offers numerous benefits, starting with a noticeable improvement in your property's EPC rating. This is crucial for landlords needing to meet current MEES compliance standards and for homeowners looking to future-proof their residence. Beyond energy efficiency, our insulation systems act as an effective barrier against condensation and damp, helping to create a healthier living environment. By retaining more heat, you will see a reduction in fuel usage and a significant increase in overall thermal comfort throughout the year.

Meeting Regulations with Our PAS Accredited Team

Compliance with UK building regulations is at the core of everything we do. As a PAS 2030 accredited company, we ensure that every project meets the latest PAS 2035 retrofit standards.

From managing planning requirements in conservation areas to ensuring the correct insulation thickness for your specific wall construction, we handle all technical details so you do not have to worry.

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.
