General Information

CONDENSATION: Since acrylic domes cannot be hermetically sealed, condensation may  form between domes. This may be objectionable when both domes are transparent. However, in most instances the condensation is temporary.

NOISE: In some installations a "popping" noise may be heard. This may occur when a tinted dome for example, under direct sunlight and a passing cloud covers the direct sunlight causing the acrylic dome to suddenly contract.

FINISH: Mill finish will be furnished on all units unless another finish is specified required.

DESIGN: Plasteco, Inc. reserves the right to make design changes without notice. However, any design changes will be presented on approval drawings.

SAFETY: Plasteco, Inc. skylights are not designed to support body weight. For information on Fall Protection on Plasteco Skylights refer to our FallGuard Skylight Screen section.

Responsibility

Plasteco is responsible for furnishing skylights to fit specified outside curb dimensions or roof opening dimensions. It is the responsibility of others, however, to assure the integrity, strength and dimensional accuracy of the supporting structure- factors which are essential to a successful installation.
