The team at EOS are celebrating yet another prestigious award win, picking up a trophy at the Housebuilder Product Awards for Best External Product for our Thrubuild® system innovation.

Rewarding outstanding achievements and celebrating ‘best in class’ products and systems – as a winner of a Housebuilder Product Award, EOS automatically becomes a finalist in the Product of the Year category at the Housebuilder Awards 2021, competing for the top prize with the other category winners.

Our Managing Director Steve Thompson said of this success: ‘Our widely acclaimed Thrubuild® system range is the result of close collaboration between Etex brands – EOS, Siniat, Promat and FSI. As a group, we are committed to technical excellence and have some of the best fire experts in the UK on our team. They work closely with certification bodies to jointly develop and design technical solutions. We are delighted this work has been recognised by the respected judging panel at the Housebuilder Product Awards. ‘

Fully Certified Solution
A fragmented supply chain results in components being offered by a multitude of manufacturers, therefore warranties are complex, for very limited timescales or simply non-existent. This uncertainty also extends to the costs involved, the speed of build and the quality of the final outcome.

In response to these challenges, EOS has developed a range of Thrubuild® light steel frame panelised systems, offsite manufactured to rigorous quality standards. The Thrubuild® system range has been engineered for structural performance to the latest Eurocode and has completed rigorous fire, acoustic, weathering, airtightness and mechanical testing.

These fast-track solutions make use of the latest products, technical know-how and manufacturing excellence of the combined team. The range of Thrubuild® systems deliver ‘all in one’ walling and flooring solutions providing crucial time and cost benefits. A system approach ensures the outcome is more predictable and repeatable, eradicating the risk of onsite variability.

The Weather Defence used in the panelised system is a revolutionary new external sheathing board, faced with water repellent material for superior weather protection. Designed exclusively by Siniat, it is strong, highly moisture resistant and A1 non-combustible. Weather Defence can be left installed and exposed for up to 12 months on site before the final cladding needs to be completed.


All components and products are rigorously tested together to ensure compatibility and system performance, enabling EOS to warrant the technical performance of their Thrubuild® range of solutions.

Fire resistance periods of 60, 90 and 120 minutes are readily achievable. When walling and flooring systems are built entirely with Etex Building Performance components and materials in line with their latest standards — Etex award a Thrubuild® 30-year warranty.
