Abstract

This invention relates to a building material consisting of organic/fibrous material composites or solid wood products, such as fibrous gypsum, paper-lined gypsum board, particle board, plywood or solid wood studs made of whitewood and redwood. The building material is treated with an anti-mold and anti-flame agent,such as boric acid and borax.

Description

Building material
This invention relates to a building material consisting of organic/fibrous material composites or solid wood products, such as fibrous gypsum, paper-lined gypsum board, particle board, plywood or solid wood studs made of whitewood and redwood.
The current building materials and building systems are based on the traditional way of building. The principle is that the builders, architects, constructors use the building materials available on the market, i.e. what is offered for sale, for their buildings. The properties of the materials available also dictate how the buildings will be. The basic rule is as follows:
Wood burns and does not withstand humidity in closed structures where biological growth may occur (mold).
Organic materials in general do not withstand humidity in poorly ventilated and closed structures where biological growth may occur (mold).
The invention provides brand new building materials by refining and combining the buildings materials currently available on the market. The novelty is based on that organic/fibrous material composites or solid wood products are treated in such a way that the building materials are adapted and meet the requirements of the NO building system which is in accordance with BB 2008 (the Regulations of the Swedish National Board of Housing, Building and Planning (Boverket)) and which is totally new to said buildings materials in the field of construction. The materials are: fibrous gypsum, particle board, plywood or solid wood studs made of whitewood and redwood. The building materials are suited for constructing light partition walls, curtain walls, floor frameworks, intermediate floor frameworks and ceilings.
The invention is characterized in that the building material is treated with an anti- mold and anti-flame agent, such as boric acid and borax. The boric acid and borax can be dis-solved in water before the treatment of the building material. Even a binder, such as carboxymethyl cellulose, can be added to the anti-mold and anti- flame agent. The novelty is a refining treatment result on five products.
The novelty is that the treatment result refines and creates a new unique technically- extended field of application for the above-mentioned building materials. The novelty is that a treatment result giving protection against biological growth and protection against fire is achieved through one and the same refined treatment.
The NO building system is based on approved NO products. The products must be certified under BBR 2008 Part 2, Section 6 Hygiene, Paragraph 6:5 Moisture, Chapters 6:51 and 6:52, and EU Fire Class B-sl, dO to A2.
The treatment result must be verified by authorized test institutes such as IVL Swedish Environmental Research Institute, SP Technical Research Institute of Sweden and VTT Technical Research Centre of Finland, or by similar institutes.
It is a novelty to create the possibility of presenting a re-fined moisture-ratio certified particle board which has a critical humidity level higher than 87 % RH, up to 97 % RH, and which is adapted and included in the NO building system. It is a novelty to present a refined EU fire classified particle board B-sl, dO to A2, adapted to and included in the NO building system.
It is a novelty that these two refined combinations are included in one and the same product. It is a novelty to create a refined wood stud from solid wood material, from whitewood or redwood, designed as a building stud and a construction stud which have not only a moisture-ratio certification but also have a critical humidity level higher than 87 % RH, up to 97 % RH, as well as EU fire class B-sl, dO to A2, and are which are adapted to the NO building system.
It is a novelty to be able to present a refined fibrous gyp-sum board which contains organic material and has a moisture-ratio certification and a critical humidity level higher than 87 % RH, up to 97 % RH, and has a retained fire class and is adapted to the NO building system.
It is a novelty to be able present a traditional paper-lined gypsum board which can get a moisture-ratio certification and a critical humidity level higher than 87 % RH, up to 97 % RH, and which has a retained fire class and is adapted to the NO building system.

Claims

Claims
A building material consisting of organic/fibrous material composites or solid wood products, such as fibrous gypsum, paper-lined gypsum board, particle board, plywood or solid wood studs made of whitewood and redwood, characterized in that the building material is treated with an anti- mold and anti-flame agent, such as boric acid and borax.
