FSC Certification
In 2004 the Ecoplus range pioneered the use of FSC Pure timber in UK window manufacturing and is still probably one of only a handful of UK window ranges to use FSC Pure timber. FSC is the only timber certification scheme endorsed by all major environmental
NGOs such as Greenpeace, FOE and WWF. There are several levels of FSC Certification. FSC Pure means that all timber
used is certified. Other grades include FSC Mixed, in which some material is
FSC and some from 'controlled' (ie legally logged) sources and FSC Recycled.
For a company to offer an FSC Certified product, they must have been through a
rigorous auditing process to ensure 'chain of custody' of the timber used from
forest to product.

Engineered timber
Engineered timber includes both lamination and finger jointing of timber, using
modern high performance adhesives. As well as offering the optimum use of
resources, this has three major advantages.
• Lamination increases stability of
timber
• Virtually no knots or surface defects
• Surface layers are cut to ensure that
grain is vertical to the surface, which
dramatically reduces the risk of surface movement and splits
