Designed For The Next Generation Of Housing

The Bio Twin Wall System from Sydenhams Timber Engineering combines exceptional structural performance with natural, renewable materials. Manufactured using precision timber framing and insulated with UK-grown hemp, this carbon-smart system stores more carbon than it emits. It removes key barriers to offsite timber construction, offering a highly attractive and fully mortgageable alternative to traditional cavity wall systems.

Built On Trusted Certifications

Fire Certified And Fully Accredited

Safety and compliance are built into the core of this system. It is rigorously tested to REI 60 from both sides, providing complete assurance for Building Control and on-site safety requirements. Furthermore, with BOPAS accreditation and STA Gold status, the Bio Twin Wall System meets strict warranty standards to give full confidence to lenders, insurers and warranty providers.

The timber structure rests on a grey blockwork foundation against a clear blue sky.

Build Ready And Flexible

We have designed this system for maximum on-site efficiency. It is available for both open and closed panel delivery with versatile options for manual or crane installation. Because it is precision-manufactured off-site, it significantly reduces your overall construction period while remaining fully compatible with a wide range of cladding options including timber, render, brick and composite finishes.
