Certifications

With constant attention to the success of every product, from the smallest particular aesthetic reliability of the materials used, Verrecchia Joinery Doors puts all its products with accurate laboratory tests that certify the quality and water resistance to ' air and the transmittance (kept warm and cold), ie all those external factors that can affect your window.

Verrecchia Joinery Ltd. The company has obtained a declaration of conformity to Directive 89/106/EEC on its products after having passed the laboratory tests at the following accredited institutions

Tests done on our windows that certify the conformity CE

Permeability  / UNI EN 1026 - UNI EN 12207

The permeability is characteristic of a closed frame leaving air filter when there is a difference in pressure between the inside and the outside lower the volume lost, the greater the quality of the frame.
The test methodology is established by UNI EN 1026.
The resulting classification is according to UNI EN 12207, which provides four classes of performance (1,2,3,4), where Class 1 = worst class, Class 4 = best class

Wind resistance / UNI EN 12211 - UNI EN 12210

Means for wind resistance capacity of a frame that under significant pressure and / or depressions, such as those caused by wind, maintains a permissible deformation preserves the initial properties and safeguard the personal safety of users.
According to UNI EN 12210 the frame can be classified into five classes for the wind pressure (1,2,3,4,5) and three classes for the arrow on the front (A, B, C) whose combination provides the classification of the window (C3, B5, A1, etc.)..
A frame classified C5 (Summary) exceeds undamaged pressure of 300 kg / sq m, equivalent to a wind speed of around 230 km / h.

Waterproofing / UNI EN 1027 - UNI EN 12208

The watertightness and 'the ability of a fixture to prevent infiltration of water when there is a pressure differential between inside and outside.
The classification is done using the UNI EN 12208 for nine classes reached by frame (1,2,3 ... 9), combined with the letter A (in case of windows completely exposed to water) or B (in case of fixtures placed in a niche with higher veil protects them dall'irrorazione direct). Class A is better than B, as 9A is better than 1A.

Trasmittaznza Thermal / UNI EN ISO 10077-1

The coefficient of heat transmission (Uw) indicates how much energy dissipates through the window surface.
The determination is conducted according to UNI EN ISO 10077-1 that relates various parameters such as thermal transmittance of frame (UF), glass (Ug), window size, window area, etc..
Less is this value, the greater the quality of the frame; is expressed in WM2 / K °.
