energystore launches spacebead - the UK's first aerogel-based injected insulation system
energystore has unveiled energystore spacebead®, a next-generation injected insulation system, as the UK’s Warm Homes Plan drives unprecedented demand for high-performance, energy-efficient building solutions. With billions earmarked to upgrade millions of homes, insulation is emerging as a critical factor in delivering lower energy bills and meeting net zero targets.
While policy attention often centres on renewables, improving the building fabric remains essential. The Warm Homes Plan is raising expectations across the sector, with stricter efficiency standards and a clear push for higher-performing materials in both new build and retrofit projects. This shift is accelerating the need for innovative insulation that can meet evolving regulations without adding complexity or cost.
For housebuilders, developers and retrofit professionals, this signals a clear market shift:
Higher performance expectations for building materials
Growing demand for cost-effective, future-proof solutions
Increased pressure to meet regulations such as the Future Homes Standard
As a result, this shift is accelerating the need for innovative insulation that can meet evolving regulations without adding complexity or cost.
Designed to meet these challenges, spacebead® combines EPS beads with advanced aerogel technology to deliver market-leading thermal performance. Its low thermal conductivity enables improved energy efficiency and EPC ratings, while its injected application ensures quick installation and minimal disruption - ideal for modern construction demands.
The system achieves a thermal conductivity of just 0.029 W/mK, making it around 15% more efficient than traditional injected insulation options.
In practical terms, this can translate into:
Up to 20% improvements in heating efficiency for homes
Enhanced EPC ratings for both new builds and retrofit projects
Reduced energy bills for homeowners
As the industry adapts to tighter standards and rising expectations, the launch of spacebead® signals a step change in insulation capability. With the Warm Homes Plan reshaping the market, energystore’s latest innovation positions insulation at the forefront of the UK’s transition to more energy-efficient homes.
For energystore, the message is clear: the future of energy efficiency starts with better insulation—and that future is already here.
