01
Hi-Grade Alloys core
Hi-Grade Alloys is infinitely recyclable, retaining its inherent properties through repeated reuse. Whole-system recyclability remains subject to the controlled specification and supporting evidence.
Building Engineering Envelope

The system
A wall designed like a product.
THOM brings the main envelope functions into one modular, mechanically assembled platform.
Building Engineering Envelope
Data centres
Treat the envelope like infrastructure.
A controlled envelope platform for demanding thermal, programme, logistics and specialist requirements.
Explore data centresModularity
Scale. Move. Adapt.
Flat-pack logistics and mechanical assembly are designed to reduce the construction burden that travels with the project.
Explore deployable infrastructure
Architectural freedom
The envelope should enable the architecture.
A repeatable panel platform designed to support different project types, finishes and configurations without returning to a fragmented wall build.
Designed in England
Precision engineering before site work begins.
THOM is developed as a controlled product platform, with detailed engineering information protected and released through appropriate technical diligence.
Explore the technology
01
Designed around hi-grade alloys, modularity and future adaptability.
Sustainability and end-of-life statements remain subject to the controlled product specification and supporting evidence.
Open the evidence register02
Modular by design
Mechanical assembly and flat-pack logistics are designed so panels can be dismantled, relocated and re-deployed rather than demolished.
03
Future adaptability
A controlled product platform that can be re-evaluated, moved and adapted across the asset lifecycle — with performance statements held to the published evidence basis.
What the platform is designed to do
Performance is not an add-on.
THOM is designed so the envelope functions are considered together, not added one trade at a time.
THERMAL
Designed for very high thermal performance
Target c. R50, subject to final validated specification.
See the evidence pathFIRE
Fire performance engineered into the pathway
Reaction-to-fire classification route to be established under EN 13501-1 and fire resistance to be tested separately under EN 1364-1. No achieved A1/A2 or EI duration claim.
See the evidence pathACOUSTIC + RF
Specialist performance designed in
Acoustic performance to be established by accredited ISO 10140 testing; no validated numerical claim currently approved. RF/EM attenuation is a target capability subject to validation; no numerical shielding claim is currently approved.
See the evidence pathThese statements describe current controlled design targets or intended capabilities unless an approved THOM publication explicitly states a validated or certified result. Final system performance remains subject to the relevant accredited validation and certification.

Where THOM matters
Different sectors. One envelope idea.
Choose the problem you are trying to solve, then explore the THOM pathway for that sector.
THERMAL + SPECIALIST ENVELOPE
Data centres
A controlled envelope platform for demanding thermal, security and infrastructure environments.
SPEED + PREDICTABILITY
Housing
A repeatable panel system designed to reduce wet trades, interfaces and site uncertainty.
LIGHTWEIGHT + RAPID ASSEMBLY
Deployable infrastructure
Flat-pack logistics and mechanical assembly for remote, defence and specialist applications.
CONTROLLED UPGRADE PLATFORM
Container & technical units
An engineered envelope route for compact technical, storage and modular spaces.
Engineered to endure
A wall built like infrastructure, not like a brochure.
THOM treats the envelope as permanent environmental infrastructure — engineered, controlled and built to outlast the building around it.
One controlled platform
Every function engineered into one panel.
THOM replaces a stack of separate products and trades with a single, factory-controlled envelope system — so performance is designed in, not assembled on site.
Protected IP
Proprietary architecture, patent applications in progress.
The internal engineering stays protected and is disclosed only through controlled technical diligence. Public pages focus on outcomes, not the recipe.
Built to last
Hi-Grade Alloys-led, designed for circular recovery.
A durable, corrosion-resistant envelope designed for long service life and material recovery at end of life; whole-system recyclability remains subject to lifecycle validation.
