Problem description
Wood does not like moisture. Not only direct contact with water but also high humidity is dangerous for wood and for chipboard and MDF boards in particular. A damp environment, with relative humidity exceeding 70%, may be present in any house, e.g., in the bathroom, the kitchen or under the roof. Wood may also be exposed to high humidity during the construction phase. This may be due to adverse weather conditions, but also after plastering the walls or pouring the floors the relative humidity inside a building can reach 90% or higher.
Moisture causes wood to change (linear expansion, swelling) and in the case of board material it may have a highly adverse impact on its technical characteristics (such as rigidity, bending strength). In the most critical of environments, even surface fungus may occur. Solutions
Sawa BCA Boards are a Moisture Resistant panel material and it can be specified for use in the most strenuous humid domestic interior conditions where dimensional stability and retained strength are of great importance. Some examples of application would be kitchen & bathroom furniture, skirting boards, mouldings, wall cladding, shelving and flooring.
Sawa BCA Boards are manufactured using MDI polyurethane as a binding agent which produces a "Zero Formaldehyde" or "Formaldehyde Free" material.This special production process and other featured characteristics positions the finished product far above the common standard values. Applications
Sawa BCA Boards can be applied in service class 2 environments (not in outdoor applications) and are capable of withstanding accidental contact with water. The products are characterised by low swelling and limited linear expansion when exposed to an increased humidity level. Brief exposure to water (e.g., rain shower at a site) will not substantially affect the mechanical characteristics. Sawa Moisture-Resistant BCA Boards can be melaminated, laminated or coated with another surface finish without any problems. Sawing and milling is possible using standard tools. Sawa BCA Moisture-Resistant Boards are used for: - House construction
- Roof elements
- Flat roofs
- Load-bearing floors - Interior decoration
- Bathroom furniture
- Laminated floors
- Kitchen decoration - Other possible applications
- Concrete formwork
- Wall constructions (possibly with tongue and groove)
- Packaging material
- Special fire requirements
