Why Your Home Might Be Colder Than It Should Be
Even if your home has existing insulation, it could be silently underperforming due to age, material degradation, poor installation, or external factors. This leads to common issues like persistent cold spots, dampness, mould, and frustratingly high energy bills.
- 01. Innovation: Older materials can't match today's efficiency.
- 02. Attenuation: Insulation settles, slumps, or deteriorates over time.
- 03. Poor Install: Initial gaps and voids from original build.
- 04. Intervention: Building work can disturb existing insulation.
- 05. Moisture: External maintenance issues can allow water in.

The most common questions
What is thermal bead (bonded bead) insulation?
Thermal bead insulation, often called bonded bead cavity wall insulation, involves injecting specially formulated polystyrene beads into the cavity between your home’s outer and inner walls. A bonding agent holds the beads together, creating a highly effective thermal barrier that reduces heat loss and improves energy efficiency.
How does thermal bead insulation work?
The beads are injected through small holes drilled in the external walls. Once inside, they fill the cavity completely, forming a lightweight, moisture-resistant layer that helps keep your home warm in winter and cool in summer
What are the main benefits of thermal bead insulation?
Improved thermal efficiency: Reduces heat loss by up to 30%, making your home warmer and more comfortable.
•Lower energy bills: Improved insulation means less energy is needed for heating and cooling, which can save hundreds of pounds per year.
•Moisture resistance: The impermeable bead barrier forces any water ingress to the damp proof course at the bottom of the cavity, reducing the risk of damp and mould..
•Long lifespan: The insulation is durable and does not degrade over time.
•Environmentally friendly: Reduces your ongoing carbon footprint because of decreased energy required to heat you home.
Is thermal bead insulation safe for my home?
Yes, thermal bead insulation is non-toxic, non-irritant, and fully fire-resistant. It is approved by leading industry bodies and meets or exceeds current building regulations
Will the insulation cause damp or moisture problems?
Properly installed thermal bead insulation does not cause damp. The beads allow water to drain downward, and the material itself does not absorb moisture. Issues with damp usually arise from poor installation or pre-existing wall damage, not the insulation itself
How long does installation take?
For a typical semi-detached house, installation usually takes just a few hours. The process is quick and minimally invasive, with only small holes required in the external walls
Is my home suitable for thermal bead insulation?
Most homes with cavity walls are suitable. A professional survey is recommended to check for any pre-existing issues or incompatibilities before installation
