Wind Resistance for External Blinds
External shading systems such as blinds can reduce heat gain almost to zero, and can result in savings of 65% on air conditioning costs. They remove the internal clutter of boxes or rollers around windows, and can even provide insulation in winter.
In recent years, there has been a confusion of sales messages about wind resistance and increasingly bold statements about wind speeds and product thresholds. As a result, at European level, a number of interrelated and complex standards have been introduced or updated to regulate this area.
Whilst it is crucial for architects and design teams to have an awareness of the key points when specifying shading solutions, the plethora of interrelated standards that regulate shading systems does not make for light bedtime reading.
- CE mark external blinds to these classifications, or specify that they are not classified.
- Define a windspeed over which blinds must be retracted.
- Verify that non-retractable parts of their products can withstand 800 N/m2 without deformation.
