6. For better performance and protection, any exterior
folding system should be installed under an overhang
or with other similar protection.
7.
For better performance it is recommended that
all dead loads such as upper levels, roof, etc. be
constructed before a unit is installed.
Properly flash and waterproof around the perimeter
of the opening, especially at the sill. Make sure you
seek proper professional advice for the appropriate
construction needed for your particular application. DO
not install unit in structures that do not allow for proper
management/drainage of moisture.
To avoid future problems, do not install your unit until the
rough opening has been correctly prepared.
