INDOOR AIR QUALITY AND VOCs
Volatile Organic Compounds (VOCs) occur naturally in wood and wood-based products, and also in solvent-based finishes.
VOCs in the air can cause health problems in higher concentrations. However, the levels of VOC emissions within buildings from wood products and from factory-applied finishes are well below the levels at which any such effects might be expected.
In accordance with the explanations below, we consider that our standard core materials and solvent-based finishes for doors and panels meet the requirements for credits for indoor air quality under BREEAM or LEED (see Background for more details of these schemes).
o Shadbolt door and panel core materials meet the requirement for a credit under BREEAM by virtue of achieving E1 emission level in accordance with EN 13986.
o Factory-applied paints and varnishes are not deemed to contribute to VOC emissions under BREEAM.
VOCs may occur in Shadbolt products from two sources: wood-based core materials, and solvent-based finishes (lacquers, paints and stains).
Core materials All standard Shadbolt door and panel core materials satisfy the most stringent European Class E1 for formaldehyde emissions.
Shadbolt’s E1 classification is based on:
- Tests to Harmonised European Standard hEN 13986 or other compatible national European standards, eg DIN, DIB.
- Use of wood-based materials to which no formaldehyde-containing substances are added during production and which therefore may be classified E1 without testing, eg solid wood frames.
Finishes Our standard solvent-based finishes are applied and cured in controlled factory conditions. BREEAM rules refer specifically to finishes applied on site. Factory-applied coatings are therefore deemed not to contribute to VOC emissions under BREEAM.
Alternative water-based finishes are available, but they are expensive to procure and much more time consuming (and therefore expensive) in application and curing.
