Glas Vision 3000 windows have been fully independently tested by ift Rosenheim in Germany (full test results are available on our downloads page) for Resistance to Wind Load, i.e. the ability of the window system members to resist deflection under positive and negative static and dynamic wind loads tested in set steps from 400Pa up to 2000Pa.
The sample windows were tested to EN 12211 : 2000-06 and the results are classified in accordance with EN 12210 : 1999-11.
The majority of UK buildings are subject to design wind loads of no more than 1200Pa, class A3. In the most extreme weather conditions of the Scottish Highlands and Islands design wind loads can rise to 2000Pa or class A5.
The performance levels achieved by the Vision 3000 product are well in excess of these requirements and all windows attained a static window load class rating of C5/B5 and a rating of class 5 under dynamic window loads.
With the outstanding performance figures, you can be rest assured that the
Vision 3000 product will be suitable for any UK location.

Static Wind Loads
All window types classified (according to EN 12210 : 1999-11) as class C5/B5 up to Class 5 pressures of +/- 2000Pa where frame members measured frontal deflections of less than 1/300th of the height.
Dynamic Wind Loads
All window types classified (according to EN 12210 : 1999-11) as class 5 up to pressures of +/- 1000Pa where no malfunctions were detected.
• Tests carried out to EN 12211 : 2000-06 and are classified as EN 12210 : 1999-11.
