Window Installation Instructions - General Overview Section -
D. Plumb / Level / True
1. All materials are to be installed plumb, level, true, and in proper alignment and relation to
established line grades. Products are to be installed maintaining tolerances of 1/8” in
12’-0” of length.
E. Isolate Aluminum
1. Isolate aluminum that directly contacts masonry or incompatible materials with a heavy
coat of zinc chromate, plastic isolators, or bituminous paint.
F. Poured and Debridged and Thermal Strut Sections
1. Do not drill, punch, penetrate, or alter the poured and debridged thermal break or
extruded thermal strut in any manner.
G. Fastening
1. Fastening means any method of securing one part to another or to adjacent materials.
Due to varying opening conditions, window configurations, design pressures, and
methods of anchorage (subframe, “F” anchors, etc.), perimeter fasteners are not
specified in these instructions. For anchor fastening, refer to the shop drawings or
consult the project design professional.
H.
Blocking
1. All blocking and shims will be high strength plastic or non-corrosive materials Not by
EFCO. Blocking must be of sufficient size and shape to support the frame at all
anchorage locations. The blocking must prevent the anchorage fasteners from bowing,
racking, twisting, or distorting the window frames and accessories in any manner.
I. Sealant
1. Sealants must be compatible with all materials they contact, including other sealant
surfaces. Any sealant details shown herein, unless specifically called out to be by
EFCO, are by others.
It is not EFCO Corporation’s position to select or recommend sealant or caulking types
and will not assume liability or responsibility thereof. Consult the sealant supplier for
recommendations relative to compatibility, adhesion, priming, tooling, shelf life, and joint
design. It is the sole responsibility of the customer to perform all sealant adhesion and
compatibility testing that is required by the sealant manufacturer of choice.
4. Building Codes
Glass and glazing codes governing the design and use of products vary widely. EFCO does not
control the selection of product configurations, operating hardware, or glazing materials; therefore,
we assume no responsibility in these areas. It is the responsibility of the owner, architect, and the
installer to make these selections in strict conformity to all applicable codes.
These recommendations are for general erection procedures only. For actual job
conditions, see the details on the shop drawings. For perimeter anchor type and spacing,
refer to the approved shop drawings or consult the project design professional.
