The combustion performance of the existing building materials is classified into four classes:
Class A: non-flammable building materials Class B1: flame-retardant building materials
Class B2: flammable building materials Class B3: combustible building materials
1. Non-flammable components: components made of metal, brick, stone, concrete and other non-combustible materials, called non-flammable
components. Such components will not occur to fire, micro-burning and charring in case of open flame in the air or high temperature. Brick walls,
steel roof trusses, reinforced concrete beams and other components are all non-flammable components.
2. Flame-retardant components: components made of flame-retardant materials or made of non-flammable materials and applied with a protective
layer of combustible material. Such components will not be easily occur to fire, micro-burning and charring in case of open flame in the air or high
temperature, and after the fire source is removed, the burning or micro-burning will stop immediately.
3. Flammable components: components made of flammable materials. Such components will immediately occur to fire or micro-burning in case of
open flame in the air or high temperature, and after the fire source is removed, the burning or micro-burning will continue. Wood pillars, wood
frames, wood beams, wood stairs, wood joists, fiberboard ceilings and other components are all flammable components.
4. Combustible components: without any flame-retardant effect, highly flammable, thus the potential of fire risk is high.
[Authority] Modified Scrimber of Jingbo Wood-based Material Co., Ltd. - a new
height of fire resistance of wood-structure buildings
What is a modified scrimber? The so-called wood modification means to the physical or chemical processing method to improve or modify the
physical, mechanical and chemical properties and the structural features of wood. The purpose is to improve the natural decay, acid, alkali and flame
resistance, the mechanical strength and the dimensional stability of wood. And the wood through modified reconstitution treatment is called modified
Our company’s modified scrimber is manufactured by using a wood reconstitution method, firstly a chemical modification treatment is carried out
for the wood, and then a densification treatment and heat treatment. The physical and mechanical properties are superior to those of natural hard
wood, the decay, acid and abrasion resistance as well as the strength and the hardness are significantly improved, the dimensional stability is good to
avoid deformation, and the natural texture of wood is retained.
The combustion performance indicators of the wood pillars, wood frames, wood beams, wood stairs, wood joists, wood windows and other wood
components in the existing traditional wood architectures are in Class B2, and the components are combustible materials and may immediately occur
to fire or micro-burning in case of open flame in the air or high temperature. According to the testing by "China National Center for Quality
Supervision and Test of Fixed Fire-extinguishing Systems and Fire-resisting Building Components", the combustion performance of our company’s
modified scrimber has reached Class B1, the modified scrimber will not occur to fire, micro-burning and charring in case of open flame in the air or
high temperature, in addition, after the fire source is removed, the burning or micro-burning will immediately stop, thus our modified scrimber has reached the highest class in wood products!
