Background/Justification
As a result of the many technical
enquiries received it has received, the CWCT has identified a need for
short practice notes to inform both specifiers and manufacturers of cladding,
windows and curtain walling. Increasingly, design decisions are being passed
to manufacturers, many of whom are small fabricators and assemblers. Some
decisions, however, such as selection of finishes and materials, are still
being made by specifiers who have less in-depth technical knowledge of
products, which are becoming more complex.
Objectives
Technical notes are being
written by the CWCT, reviewed by industry and published as reviewed technical
notes. The notes are aimed at construction industry professionals who need
to understand products and design and performance specification issues.
A total of 30 short technical
notes will be produced covering the most frequently asked questions about
cladding. These include:
-
Weather performance
-
Thermal performance and condensation
-
Glass
-
Performance and testing
-
Design installation and surveying
-
Environmental issues
The final list of technical
papers will focus on particular aspects under the broad headings listed
above, either to act as quick reference documents providing best current
knowledge/practice or simplified design calculations.
