Glulam according to DIN EN 14080:2013-09
The harmonised European product standard for glulam timber
|Warning: At the time of producing this document the use of glulam timber according to DIN EN 14080 is not regulated in Germany. Glulam timber according to DIN EN 14080 may be manufactured and traded in Germany but not be installed in buildings! |
EN 14080: 2005-09 „Timber Constructions – Laminated Timber Requirements“ is the harmonised European product standard for glulam timber, i.e. it belongs to the standards with which the European Commission will achieve free trading of building products within Europe. Harmonised European product standards should urgently replace competing national product standards. With the publishing of a harmonised European product standard in the European official gazette, therefore, a coexistence phase is always announced, at the end of which competing national rules must be withdrawn.
For EN 14080: 2005-09 a coexistence period has been defined as beginning on 01.04.2006 and expiring on 01.04.2007. The coexistence period in the meantime has been extended by three years and thus now expires on 01.12.2010.
In principle the harmonised product standard should be already applicable within the coexistence periode and the national standards up until now allowed only as an alternative. In fact products according to EN 14080 for the following reasons are allowed to be manufactured and traded in Germany but not yet installed.
Tradable in Germany but not free for installation without residual and applicable standards
In a similar manner the use of glulam timber according to EN 14080: 2005-09 should be regulated by the applicable standard DIN V 20000-3 „Application of Building Products in Buildings - Part 3: Glued Laminated Timber”. In this future application standard among others the derivation of allowable stresses from the characteristic strengths defined in the European standards is described and the use of glulam timber of formaldehyde class E1 is made compulsory.
