• Establishes new formaldehyde emission limits for<br />
composite wood products; particleboard (PB),<br />
medium density fiberboard (MDF) and hardwood<br />
plywood (HWPW) panels.
Engineered wood products have to<br />
fulfil modern requirements<br />
CARB<br />
• Applies to products sold, supplied, used, or<br />
manufactured for sale in California<br />
• Requires finished goods to be made from<br />
compliant PB, MDF and HWPW panels<br />
• Establishes enforcement program<br />
• Includes sell-through provisions
Engineered wood products have to<br />
fulfil modern requirements<br />
• ATCM (Airborne Toxic Control Measure) allows<br />
exemption for manufacturers using no-added<br />
formaldehyde (NAF) or ultra low emitting<br />
formaldehyde (ULEF) resin systems<br />
• Requires application<br />
• Approvals case by case<br />
– CARB Executive Order; 2-year approval<br />
• 14 CARB approved (12 NAF; 2 ULEF)<br />

EPF-S (Europe)<br />
New proposed standard of the “European Panel<br />
Federation”<br />
• <strong>Design</strong>ed to close the formaldehyde discussion by offering<br />
a very low emitting board to the user at affordable cost<br />
• Based on uniform factory production control rules and<br />
frequent external supervision checks in accordance with<br />
European standards as well as long-standing European<br />
and national regulations<br />
• Boards achieve the formaldehyde expectations of IKEA<br />
and CARB II
Engineered wood products have to<br />
fulfil modern requirements<br />
• Higher comfort<br />
• Better maintenance of value<br />
• Clear energy cost savings<br />

Summary<br />
• Engineered wood products are established as<br />
construction material.<br />
• There are a variety of innovative engineered<br />
wood products developed and proven in<br />
standardization work.<br />
• Wood products can and have to fulfil modern<br />
requirements in the direction of ecological<br />
position.

First applications of PURBOND in the glulam<br />
industry in Switzerland.<br />
PURBOND HB 110 got the approval in<br />
accordance to DIN 1052, after approx. 3 years<br />
testing in comparison to PRF adhesives.<br />
Market introduction of PURBOND HB 110 –<br />
made the success of “KVH” solid wood timber<br />
in Germany. - Since 1995 until 2008 approx. 30<br />
miom 3 KVH was produced.<br />
Widely spread the technology into the different<br />
application finger jointing and face gluing.<br />
Starting with cross laminated timber.
Physical Performance<br />
The quality of an adhesive bond can be defined<br />
according to ultimate strength, resistance to<br />
degradation by moisture, resistance to heat and<br />
elastic behavior.<br />
1. Strength<br />
2. Durability<br />
3. Long-term performance<br />
4. Elastic behaviour and resistance to creep<br />
5. Resistance to high temperatures

Our pursuit of product excellence has seen us always looking for proven<br />
technologies that give the finished product an environmental or technical advantage.<br />
We were one of the first sites to utilise <strong>Purbond</strong> Polyurethane Adhesives –<br />
Formaldehyde free and fully waterproof (awarded <strong>Purbond</strong> customer achievement<br />
award for 2007).

Tendency with gluing of wooden<br />
construction<br />
• Wood as construction material is increasing and<br />
the image is changing.<br />
“Old” prejudices<br />
• Wood is specially fire endangered<br />
• Wood is cheap<br />
• Wood does not look nice<br />
• Wood is not noise protective<br />
• Wood is short-lived, it rots and moulds
Effective benefits<br />
Wood<br />
• is easy to process<br />
• is qualified for prefabrication<br />
• has high strength with low weight<br />
• is easy to combine with other materials like steel, glass,<br />
etc.<br />
• is natural, aesthetic, cosy<br />
• is air humidity regulating, heat-insulating, diffusible,<br />
antistatic<br />
• The resistance to fire can be calculated<br />
• Wood has high surface temperature<br />
• Wood constructions are energy efficient<br />
• Short construction time because no humidity brought in
Effective benefits<br />
Ecological benefits:<br />
• Renewable<br />
• CO 2 neutral<br />
• Local availability / short transit<br />
Economic benefits:<br />
• Short construction time<br />
• Low weight with good static performance<br />
• Good thermal insulation<br />
• No non-recyclable waste
Wood the ideal construction material
