Solid Wood Laminated profiles for joinery (windows scantling and doorframes)Technical Data
DESCRIPTION
CompositionTwo or more layers of solid wood that can have finger joints and are glued together in the longitudinal direction.DKD Whole external layers and whole internal layers or with finger-joint union.KKK Internal and external with toothed union.
Woods: Chestnut, oak, beech, red eucalyptus, iroko, larch and red pine
Gluing: According to the standards UNE EN 204/205 class D4 for covered exterior use.
Moisture content: depending on exposure and use. In any case, the moisture content of the sheets of a profile do not differ in morethan ± 3%
Exposure Moisture Content (%) Examples of final uses
Interior (indoor) 9 ± 3 Interior doors, stairs
Exterior (outdoor) 12 ± 3 Exterior doors, windows
The requirements for this product are defined in standards:
- EN 942: Timber in joinery; General requirements.
- UNE-EN 14220: Timber and wood-based material in external windows, external door leaves and external doorframes;Requirements and Specifications.
- UNE-EN 13307-1: Timber blanks and semi-finished profiles for non-structural uses. Requirements
QUALITYAccording to quality classes defined in the standard EN 942 for wood carpentry elements (J2, J5, J10 and J20), depending on thepresence and frequency of the singularities of the wood.
