Manufacturers are concerned solely with the materials or systems they manufacture.
They do not provide the necessary information to properly evaluate their products’ useful-
ness in a composite envelope. Their material is not checked or tested for compatibility with
adjacent materials used in proposed envelopes.
The specified termination and transition details are often not those tested or typically
used by a product manufacturer. A manufacturer often provides insufficient instructions for
incorporating proper details for expected conditions and compatibility of their products
with other envelope components.
Most manufacturers will, however, offer detailing suggestions and complete laboratory
or site tests, if required to ensure the inclusion of their product in a project. Manufacturers
have technical resources available to them that are not immediately available to a designer
or building owner.
Manufacturers should become involved in the design and testing process that can bring
a project to a successful completion. Their intricate knowledge of their materials or sys-
tems and suggestions for termination and transition detailing should be consulted as a basis
for preliminary design requirements.
Manufacturers often are capable of providing laboratory analysis and testing of their
products under the proposed project conditions. This provides a means to determine
acceptability of present design requirements or to suggest alternate designs. It also deter-
mines the compatibility of their products with other envelope components.
Manufacturers representing the various envelope components can become involved with
the final designing of a composite envelope, reviewing and suggesting revisions to ensure that
