Specialist contractors
Site testing
The quality and performance of a bulding envelope are totally dependent on the standard of workmanship and knowledge available at site. Workmanship is a dominant cause of premature failures, delayed completion and additional costs arising from rework.

It follows that adequate and knowledgeable supervision is equally important.

Qualified installers

CWCT has developed a training scheme for curtain wall installers and over 1500 installers have been trained by all of the major curtain wall system suppliers. Details of the scheme are available here.

To ensure that competent installers are used on a project it is possible to specify that at least a proportion of installers should be qualified and hold a CWCT installers card. This implies knowledge of the components being used. Other qualifications such as CSCS cards are based only on generic knowledge.

Trained site supervisors

CWCT provides training for those with a supervisory role at site. This includes the 'Managing the cladding package' course and similar in-house courses.
