Sierra is committed to not only offering installers quality and choice, but also product evolvement.
Sierra has a close relationship with its extruder and hardware manufacturer to ensure profile sizes and operational and security considerations are in line with current
user needs.
Careful consideration is given to the range of products offered, the way it works, functionality, aesthetics, design, ease of installation and durability.
Making sure accreditation such as BSI and BBA can be achieved on systems is an essential consideration in the design process involved in product development. Any product changes are tested to ensure they meet the accreditation requirements, in-house and independent testing is carried out. Testing includes weathering, security, corrosion, heat and cooling tests and past performance.
