Advantages and disadvantages of fire-retardant plywood
The suppliers of fire-retardant plywood offer a variety of panels made of different wood species and with diverse methods of flame retardant treatments. There are two main approaches to plywood treatment in order to make it fireproof. Some producers use pre-manufacture treatment when veneers are impregnated before the plywood is glued, laid up and pressed. The other option is the treatment of ready-made panels. Both technologies of fire rated plywood production provide the panels meeting various standards and requirements. However, pre-manufacturing treatment helps achieve fire-resistant properties throughout the whole panel. Plywood made of 100% impregnated veneer does not require additional treatment when being cut, drilled or sanded.
Alongside with fireproof properties, the toxicity of fire-retardant plywood is another important issue that is of great concern of the certifying bodies and end-users of the panels. The treated plywood of Plyterra Group production is non-toxic material. It resists ignition and holds up the process of burning.
The area of application of fire-retardant plywood is rather wide, It includes undergrounds, rolling stock and sea and river vessels, commercial and residential buildings, where the treated plywood is used for flooring, cladding and fitting.
Fire treatment does not influence the flatness and stability of plywood. So, the panels are suitable for various overlays and laminates. However, in some cases, humid conditions can cause the penetration of salt on the surface of fireproof plywood. This can be avoided if the panels are properly stored, handled and disposed.
Fire-retardant plywood is non-harmful and non-hazardous material. Its handling does not require additional masks, gloves or any other protective equipment.
It is worth noted that fire-rated plywood from manufacturer Plyterra Group has CE certificate. The product is also certified according to EN 13501-1, which proves its compliance to B-S1, d0 of fire classification.
