Fire retardants
Our fire retardants Texterior and Ultra have highest class B-s1,d0 (corresponds to Class 0 in British Standards). In essence they both
are water-based impregnants, the difference is in active substances.
Fire retardant impregnants (colourless)
Our Texterior and Ultra are both waterborne impregnants with highest efficacy (Euroclass B-s1,d0, corresponds to Class 0 in British Standards). They have several advantages compared to other similar products:
- Health safety and Environmental friendliness – Ultra and Texterior are halogen-free, none of the ingredients is listed as toxic, carginogenic or otherwise hazardous
- Ease of use – can be applied industrually (in coating machine or autoclave) or manually (by brush, spray, roller). Can be used in situ, for treating already installed wooden constructions, facades etc.
- No need for pressure treatment – although they can be used in autoclave
- Appearance of treated wood stays natural
Texterior provides also excellent protection against biological risks (mould, rot, decay, gfugi, termites etc).
Ultra is much more effective than competing manually applied fire retardants, providing double-protection mechanism – in addition to charcoaling of the surface it will have also slight froth, inherent to intumescent fire retardant paints.
Fire retardant for Accoya
Accoya is a world’s leading high performance wood. Created from sustainably-sourced wood, Accoya undegoes a proprietary acetylation process that permanently modifies the wood to the core. The result: an environmentally friendly solid wood with durability, dimensional stabilIity and beauty that matches or exceeds even the best tropic hardwood.
But the acetylation process does not turn the Accoya fire-proof – it burns in the same way or even better than ordinary wood. Being a ‘special wood’ also requires a special fire retardant that must be tested and certified on Accoya. Fire retardants meant for ordinary wood do not work on Accoya, and their certificates do not apply for Accoya.
Being a relatively new product Accoya is already well introduced in the building industry in more than 50 countries of the world. It is perfect for cladding, siding and facades where wood’s natural beauty is desired and sustainability and high performance are of the utmost importance. In decking, where it is important that boards do not warp, bow, twist, split, Accoya is up to the challenge.
Ultra-A is suited for application by spray, roller, brush or immersion, as well as in a coating-machine and autoclave. Treating Accoya with Ultra-A leaves the appearance of Accoya unchanged and brings out the texture and natural beauty of the wood.
Fire retardant for ThermoWood
Thermally modified wood is wood that has been modified by a process of wood being heated (> 180 °C) in absence of oxygen inducing some changes to the chemical structures of cell wall components (lignin, cellulose and hemicellulose) in the wood in order to increase its durability and dimensional stability. But all this does not turn thermowood fire-proof.
Thermo-treated wood suits well for interior and exterior cladding, terraces and floors, furniture and furnishing. But being a wood with altered properties means also that making thermowood fire-proof requires a specific fire retardant, tested and certified on thermowood. The certificates issued for regular wood do not apply on thermowood.
Ultra-TW is first fire retardant impregnant that does not require pressure treatment. It can be applied on thermowood with spray, roller, brush or immersion, and also with coating machine.
Treating with Ultra-TW does not alter the appearance of thermally modified wood. It will still look like untreated thermowood.
Fire retardant woodstains
In essence it is a 2-in-1 product, providing highest class fire retardancy together with beautiful decorative appearance.
MultiPro System produces fire retardant woodstain for both internal and external use. It can be applied manually (by brush, spray, roller) or industrially (in a coating machine). Treated surfaces do not require top coat (paint, lacquer).
Fire retardant woodstains enables to save a significant amount of time and money – instead of using two (or more) different products and work processes the desired result can be achieved with just one unique product.
