Why Is Insulation Essential for Your Llantwit Major Home?

An uninsulated room in the roof is one of the primary sources of heat loss in older homes. Without proper thermal barriers, heat escapes through the rafters, leading to draughts and increased energy consumption. By installing high-performance insulation, you can effectively stop thermal bridging, prevent the build-up of condensation, and stop black mould before it starts. For landlords in Llantwit Major, this is a vital step toward meeting the current MEES requirements and boosting your property's EPC rating.

We pride ourselves on our technical expertise and commitment to quality. As a PAS 2030 accredited company, we strictly follow PAS 2035 retrofit standards to ensure every project is handled with precision.

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited room in roof insulation, reducing heat loss, and lowering high winter energy bills across South Wales and South West England, Ferndale, and South Wales.

How long does it take to insulate a room in the roof?

+

Most projects are finished within 2 to 4 days, depending on the size of the attic and the complexity of the slopes. Because we handle the plastering through Global Plastering, we keep the timeline tight and avoid the delays that come with waiting for different trades to arrive.

Will I lose a lot of space in my room after insulation?

+

Modern insulation boards are incredibly efficient, which means we can achieve great thermal results with relatively thin materials. You might lose a small amount of space from the walls or ceiling—usually only a few centimetres—but the trade-off in comfort and lower bills makes it a very worthwhile investment.

Can I get help with the costs of insulation in South Wales?

+

There are often government grants or local authority schemes available for energy-efficiency improvements, especially for properties with low EPC ratings or for households meeting certain criteria. As PAS 2035 specialists, we can help you understand what support might be available for your specific home.

What is the difference between loft insulation and room in roof insulation?

+

Standard loft insulation involves laying mineral wool on the floor of an unused attic space. Room in roof insulation is much more detailed; it involves insulating the actual slopes, vertical walls, and flat ceiling of a lived-in space to create a "thermal envelope" around the room itself.

How do I know if my attic room is already insulated?

+

If the room feels significantly colder than the rest of the house, or if you can hear a lot of external noise, it’s likely poorly insulated. We can perform a quick assessment to check the current levels and show you where improvements can be made.
