Regulatory and certifications compliance

Referring to chapters “technical” and “user guarantee”" the deepening on the broad theme of the observance of regulations and obligations which the production and marketing of window and door frames must follow, let's anticipate briefly what are the "essential requirements" introduced by European Directive 89/106/EC and incorporated by DPR 246/1993 of the Italian law:

-mechanical strength and stability

-hygiene, health and environment

-safety of use

-protection against noise

-energy saving and thermal insulation

Each of these requirements must be certified by a licensed laboratory for testing and the results must be reported to the user.

Much attention should be paid to the benefits that the window and door frame should provide for compulsory legislation.

For example:

·       with regard to security, all the glass doors up to 1 meter from the floor must be expected of accident prevention type on both sides;

·       with regard to thermal insulation, thermal transmittance of window and door frame must be less than the maximum table on national legal ordnance and on regional laws already in force. In addition, this parameter is fundamental for obtaining a tax deduction of 55% on costs incurred to improve the energy of the house.

·       with regard to sound insulation, it is fundamental the contribution of the soundproofing of the window and door frame to observe the minimum insulation values given standardized of the surface.

As you can see even from these few outline, the performance of the windows are basic in many aspects. Therefore the choice must be prudent and supported by appropriate documentation in conformity with the current regulation.
