SUNFLEX bifold doors secure BSI Kitemark™ award

The SUNFLEX range of thermally broken aluminium, timber and composite bifold doors have become the first and only German designed and manufactured bifold door systems to secure the distinguished BSI Kitemark™ certificate.
SUNFLEX bifold doors secure BSI Kitemark™ award

The Kitemark™, one of the most recognised symbols of quality in the UK, is a registered certification mark owned and operated by BSI. The mark demonstrates the SUNFLEX range of bifold doors meet the applicable and appropriate British, European and/or international standard for quality, safety, performance and trust. Only when a company has shown that it can meet the stringent standards is it allowed to display the Kitemark on its product.

To achieve this prestigious mark, SUNFLEX products and manufacturing capabilities are independently evaluated to ensure the products conform to the necessary standards, and our quality management processes are assessed to ensure we are capable of consistently producing products of this standard. In addition to the comprehensive initial testing we are subject to a continual process of detailed audits carried out on an on-going basis.

The certification procedure includes a wide range of product testing, aimed at establishing the quality of the product - for bifold doors this includes weather performance, strength, security, impact and safety testing plus a cyclical test where the doors are opened and closed 50,000 times to simulate long term usage.

Although voluntary, achieving the BSI Kitemark™ is a serious undertaking. It’s a third party endorsement by BSI that gives confidence to any purchaser that the product performs beyond minimum requirements of a suitable standard.
