Solid masonry walls are one of the biggest causes of heat loss in older properties.

If your home has solid brick or stone walls, keeping the warmth in can be a challenge – especially during the colder months.

ProofTherm is designed to provide a high-performance insulating layer directly to the internal face of solid masonry walls, helping to:
✅ Reduce heat loss through the wall
✅ Improve thermal comfort by creating a warmer internal surface
✅ Help rooms heat up more efficiently
✅ Reduce the risk of surface condensation and mould caused by cold walls

The result? A home that feels warmer, more comfortable, and potentially more energy efficient.

Whether you're renovating a period property or improving an older home, ProofTherm offers a practical way to upgrade thermal performance without altering the external appearance.

Uninsulated walls can quickly cause problems.

Heat naturally travels through the masonry by conduction, allowing warmth to escape from your home. But that's only part of the story. Cold wall surfaces can also encourage condensation, trapping moisture within the wall and creating the perfect environment for damp and mould to develop—especially where modern, non-breathable coatings have been used.

That's why ProofTherm is different.

Rather than simply slowing heat loss, ProofTherm is a breathable insulated render system that helps improve your home's thermal performance while still allowing moisture vapour to escape naturally. This helps keep solid masonry walls warmer and drier, reducing the risk of trapped moisture and creating a healthier, more comfortable living environment.

The result? Better thermal efficiency, improved breathability, protection for your masonry, and a beautiful, long-lasting finish that enhances the appearance of your property.

Because looking after a building isn't just about keeping the heat in—it's about letting the walls breathe too.

Why Insulating Your Home Is No Longer Optional

For many homeowners, insulation is something that's only considered when energy bills rise or a major renovation is planned. However, insulation is about far more than reducing heating costs. It's about creating homes that are warmer, healthier and more comfortable to live in.

One of the biggest issues affecting UK homes today is condensation and mould. While leaks and penetrating damp are common causes of moisture problems, many cases actually stem from cold internal wall surfaces. Warm air naturally carries moisture, and when it comes into contact with a cold wall, that moisture condenses into water. Over time, this creates the ideal conditions for mould to grow, particularly in older properties with solid walls.

Unfortunately, many homeowners focus on treating the symptoms rather than the cause. Mould is cleaned away, windows are opened more frequently, or the heating is turned up in an attempt to compensate for cold rooms. While these measures may offer temporary relief, they rarely solve the underlying issue if the walls themselves remain cold.

Improving the thermal performance of a property changes that. By increasing the surface temperature of internal walls, insulation helps reduce the likelihood of condensation forming while also making rooms more comfortable and energy efficient. The result is a home that feels warmer, retains heat more effectively and provides a healthier living environment.

This is why insulating plaster is becoming an increasingly attractive option. Rather than simply providing a decorative finish, it contributes to the performance of the wall itself, making it particularly suitable for older properties where conventional insulation systems may be impractical or too disruptive.

At ProofTherm, we've developed our insulating plaster to help tackle these challenges. It's designed to improve the thermal performance of cold walls while maintaining the appearance and finish expected from a quality plaster system. For homeowners, it offers another route towards warmer, more comfortable homes. For plasterers and builders, it provides an innovative solution to a problem they're being asked to solve more frequently than ever before.

As energy efficiency, retrofit and healthy homes continue to shape the future of the construction industry, we believe materials should do more than they've traditionally been expected to. Plaster should no longer be viewed as just a finishing coat—it should contribute to the performance of the building itself.

The homes of tomorrow won't just look better. They'll perform better, and the materials we choose today will play a key role in making that happen.
