Why Ultimate FBR

Why Architects Choose Modified Wood

Ultimate FBR dimensional stability — wood cladding in rain

01 — Dimensional Stability

Stays true.
In any climate.

Ultimate FBR resists swelling, shrinking and warping under extreme weather conditions. From tropical humidity to sub-zero temperatures — the geometry holds.

2.35% volumetric swelling vs 10.04% untreated
Ultimate FBR biological resistance in tropical environment

02 — Biological Resistance

No decay.
No compromise.

Chemical modification at the cellular level blocks the pathways fungi and bacteria need to survive. No toxic preservatives. No periodic retreatment. Just lasting performance.

-86% termite mass loss vs untreated timber
Ultimate FBR long service life — Scandinavian architecture

03 — Long Service Life

Built to outlast
the structure it protects.

Class 2 durability under EN 350. Ultimate FBR outlasts untreated timber by decades — reducing replacement costs, maintenance cycles, and lifecycle emissions.

Class 2 EN 350 durability rating
Ultimate FBR eco-friendly — sustainable architecture in forest

04 — Eco-Friendly

Nature-derived.
Nature-conscious.

Modified using eco-safe organic chemistry — no heavy metals, no biocides. SVLK certified. FSC & PEFC ready. A sustainable alternative to tropical hardwoods with a significantly lower environmental footprint.

NO toxic preservatives used in modification
Ultimate FBR fire performance — high density wood

05 — Fire Performance

Dense by nature.
Resistant by design.

At 743 kg/m³, Ultimate FBR is significantly denser than untreated timber. High density naturally slows ignition and flame spread — providing an excellent base for achieving B-s2-d0 fire classification.

743 kg/m³ tested density
Ultimate FBR machinability — precision wood profiles

06 — Machinability

Precision cut.
Perfect finish.

Optimised raw material with no knots, no defects. Ultimate FBR machines cleanly — accepting standard tooling for T&G, shiplap, bevel, and custom profiles. Excellent paint, oil, and stain adhesion.

NO defects in optimised raw material
