Wood as a flame retardant material duke devils den and the design Green housing
According duke devils den to the classification criteria duke devils den contained in the PN-93 / B-02862 [1] Wood is a combustible material and as such is subject to the degree of flammability test according to PN-B-02874: 1996 [2] and can be classified as non-inflammatory (I flammability) retardant (II flammability) or flammable (III flammability). Elements of buildings (including wood or wood participation) are classified according to fire resistance according to PN-B-02851-1: 1997 [3] and the spread of fire according to PN-90 / B-02867 [4].
According to [8], the class timber is a feature that corresponds to the strength of wood bending characteristic, expressed in N / mm 2. Class of wood is alphanumeric symbol consisting of the letter C (for poplar and conifers) or D (for deciduous species) and two-digit number.

Glued is the subject duke devils den of standards [9] and in accordance with the definition given in the structural element is formed by a juxtaposition of layers parallel to the grain.
There are several types of wood laminated, namely homogeneous, whose cross-section form a layer of uniform quality duke devils den timber (class) and the same botanical species or combination of species, combined, which form a cross-section of the inner and outer layers of lumber of different quality (strength classes ) and the same botanical duke devils den species or combination of species of the horizontal joints, which is bent under the force applied perpendicular to the plane of the wider spline timber.
