Are you tired of cold walls and high energy bills? With energy costs rising and new building rules getting stricter, homeowners and builders across the UK are looking for better ways to keep homes warm. The answer might be simpler than you think: polystyrene plasterboard.

This clever building material combines regular plasterboard with a layer of polystyrene foam backing. It’s like getting two jobs done at once – you get your wall finished and excellent insulation in one go. Let’s explore how this smart solution is changing the way we build and renovate homes.

What Is Thermal Performance and Why Does It Matter?

Think of your home like a tea cosy around a teapot. The better the cosy, the longer your tea stays hot. Thermal performance works the same way – it’s how well your walls keep heat inside your home during winter and outside during summer.

When buildings have poor thermal performance, several problems happen:

In the UK, building regulations require homes to meet specific thermal standards. This means your walls need to be good at stopping heat from escaping.

How Does Polystyrene Plasterboard Work?

Polystyrene plasterboard is surprisingly simple. It’s regular plasterboard with a layer of polystyrene foam stuck to the back. The polystyrene acts like a warm jacket for your walls.

Here’s what makes it special:

The polystyrene foam contains millions of tiny air pockets. Air is a terrible conductor of heat, which means it’s brilliant at stopping heat from moving through your walls.

Key Ways Polystyrene Plasterboard Improves Thermal Performance

1. Dramatically Better Insulation Values

Traditional brick walls on their own are quite poor at keeping heat in. Add polystyrene plasterboard, and the difference is remarkable:

The thicker the polystyrene layer, the better your home stays warm.

2. Stops Heat Bridges

Heat bridges are like tiny highways where heat escapes. They happen where different materials meet – around windows, doors, and structural elements. Traditional insulation often leaves gaps, creating these heat escape routes.

Polystyrene plasterboard creates a continuous barrier across your entire wall. This means:

3. Keeps Walls Warmer

Cold walls aren’t just uncomfortable – they can cause problems. With polystyrene plasterboard, your wall surfaces stay much warmer. This means:

4. Serious Energy Savings

Better thermal performance means your heating system doesn’t work as hard. Homeowners typically see:
