Introducing the New and
Revolutionary Thrubuild® System
The EOS Thrubuild® loadbearing system uses offsite manufacture and the latest testing to deliver
structures faster, with assured performance built in. Developed in collaboration with Etex Building
Performance brands - EOS, Siniat, and Promat, the system makes use of the latest products,
technical know-how, and manufacturing excellence of the Etex Building Performance team.

The loadbearing, light steel, ‘through the wall’ system, has
been developed to form the structure of low to medium rise
buildings, up to nine-storeys, and fully tested with boarding
and insulation for confidence of design performance. The light
steel framework is panelised in the factory and delivered to site
for assembly. Partial boarding of these frames can also take place
offsite depending on the system and build process.
‘One stop’ specification
By working in collaboration with Etex Building Performance, the
loadbearing system allows a one stop specification process.
Product, structure and performance are integrated into one
package of design information.
Certification
The EOS loadbearing system is Stage 1 NHBC certified by SCI,
certificate number 20180325.EOS and Siniat manufacturing
facilities are certified to ISO 9001 and ISO 14001. EOS operate
to stringent Health & Safety standards and are certified to
ISO45001:2018. Products are CE Marked to the requirements of
products and steel structures standards.
A Different Structural Approach
Designing with light steel structural systems is not complex but
requires a different approach. It is based on transferring loads
throughout the building and through as many walls as are practical.
Internal and external walls become fundamental parts of the
primary structure, rather than just infill pieces that only carry their
own weight and directly applied loads. As a result, fire resistance
requirements often increase compared to non-loadbearing steel
as each element must be protected for the structures period of
resistance, rather than solely as fire compartments.
System Overview
The EOS Thrubuild® loadbearing system has been developed
as an integrated solution, using our range of light steel framing,
Siniat Weather Defence external sheathing board, and Siniat
Frameboard, an internal plasterboard exclusively developed for
EOS loadbearing systems by Siniat,
a world leader in plasterboard materials. These integrated
systems have been tested and assessed for compliance with the
latest regulations and standards to ensure robust and reliable
design performance.
By considering all components, systems can be relied upon
to offer excellent fire, acoustic and thermal capabilities to suit the
needs of UK single and multi-residential construction. All systems
have also been engineered for structural performance to the latest
Eurocodes.
The loadbearing system range comprises:
• Internal separating walls, between units, using twin 65mm
studs or deeper
• Internal dividing walls, within a unit, using 100mm studs or
deeper
• External walls, using 100mm studs or deeper
• Internal dividing floors, within a unit, using 150mm steel joists
or deeper
• Internal separating floors, between units, using 150mm steel
joists or deeper
