Treatment
Tanalith E Pressure Treatment
Vacuum-pressure treatment driven deep into every timber board.
Why we build with this
Anyone can brush preservative onto the surface; we drive it in. Every timber board is vacuum-pressure treated with Tanalith E before it's built into a wall, forcing the preservative deep into the grain where surface coatings never reach. That depth of protection is exactly what our 15-year anti-rot warranty, Standard and Heavy Duty alike, is built on.
Dimensions
Vacuum-pressure impregnation, not a surface coating
Every timber board is vacuum-pressure treated with Tanalith E before it's built into a wall — the preservative is driven into the wood, not just brushed onto the surface, which is what the anti-rot warranty is built on.
Benefits
- Driven into the timber under pressure, not brushed on the surface
- Backs the 15-year anti-rot warranty on every timber building, Heavy Duty included
- The industry-standard timber preservative
Worth knowing
- Composite buildings need no treatment at all — the trade-off runs the other way
