Wood is one of the most common building materials. Wooden structures are strong, durable, warm, environmentally friendly and easy to build. The main nodes in the building construction using wood are the structural frames of the roof (rafter and lathing) and inter-floor constructions.
However, apart from advantages, wood has several disadvantages. The main disadvantages of wood are its flammability and nutritional attraction factor for parasites, which are able to weaken and destroy an entire building in quite a short period of time.
At present, it is common to treat wood from bark beetles and apply fireproofing using the "classical" impregnating compositions, which, unfortunately, do not have such a pronounced and long-term effect as needed in practical terms. These compositions slightly reduce the flammability of wood, without completely eliminating it.
Our company has created a special paint coating RE-FLAME™ applied as a paint and creating a thin vapor-permeable ("breather") protective layer on the wood surface, preventing the wood surface from inflammation, fire spreading and damage by bark beetles.
The RE-FLAME™ fire-retardant coating looks absolutely similar to any ordinary wood paint on the surface. It is odorless in water-based modification and white by default with a matte surface. If necessary, this composition can be tinted in pastel colors, or painted with any paints. The fire-retardant properties of the coating begin to manifest in the case of an open flame source. Under the influence of an open fire, reaching a temperature of over 200 ºC, the components of the coating are activated, and on the surface of RE-FLAME™, there appears a hard-combustible carbonized foam with a low coefficient of thermal conductivity. The thickness of the resulting carbonized foam layer is up to 100 times exceeding the initial thickness of the coating itself. That is, a 1mm thick layer of the RE-FLAME™ coating when exposed to the flame, expands in volume forming a protective foam layer up to 100mm thick!
Thermal destruction of most types of wood occurs in the temperature range from +200 ºC to +450 ºC. Also, a prerequisite for fire spreading is the access of oxygen to the combustible surface. Thus, when the RE-FLAME™ layer is triggered, this effect is applied to two flame propagation mechanisms at once - oxygen access to the surface is blocked, and there is a barrier preventing the heat transfer from the flame source.
So, it can be concluded that the RE-FLAME™ coating is an excellent innovative tool created to eliminate the fire hazard of wooden structures and protect wood from beetles - parasites. Moreover, this composition is dozens of times more effective than any "classical" impregnating agents.
