HOW IT WORKSThe FireSure® powered by BURNBLOCK® process


Step 1. Wood is delivered!

Timber is delivered by our customers and distributors to the NTL fire treatment center.


Step 2. The wood is placed in the autoclave

The timber products are unpacked, sticked and placed in our I.S.V.E. autoclave 


Step 3. FireSure powered by BURNBLOCK 

Vacuum is applied to remove all air before filling the vessel with the patented, 100% biodegradable, all natural BURNBLOCK® solution.
The concentration of BURNBLOCK® is tailored specifically to the wood species and density, ensuring consistent, optimized fire resistance for all wood products.


Step 4. Vacuum, vacuum, vacuum

Species-specific vacuum of varied pressure and timing is applied, ensuring FireSure® powered by BURNBLOCK® penetrates the pores of the wood wood deeply, for a long-lasting, and safe treatment 


Step 5. Drying!

The treated wood is then placed in the fully automated SECAL drying kilns which use ultra-sensitive moisture probes to dry the wood to the desired moisture levels.
All under close, continuous inspection from our experienced operators.


Step 6. Wrap it up..

Once dried, all wood is packaged and stickered with premium NTL packaging or the packaging of our customers and distributors.


Step 7. Bye bye!

Wood is collected or shipped on to our customers and distributors for use in yet another sustainable, certified and safe wood construction.
