2. Ship Open For Field Glazing
The following procedures are standard practice for EFCO corporation:
A. For all ship open window lites, EFCO will provide glazing beads, bead vinyl, and
setting blocks, based upon customers noted nominal thickness and the assumption
that customer will glaze in a similar manor as EFCO standard in house practices.
(With only a few exceptions most of EFCO window products are wet glazed with a
silicone sealant between the glazing leg and glass.)
Account Representatives or Account Managers are requested to advise the
customers of this policy in writing during the review process.
B. Customer should also understand that EFCO will not supply glazing sealants.
Setting blocks will be ship in bulk with sizes based on our standard in house
practices. Adjustments to block sizes due to variations in glass size are not the
responsibility of EFCO for ship open applications.
C. Customers that advise EFCO that they will be tape glazing must advise us of their
actual glass thickness and dimensional allowance for tape and cap bead for
appropriate bead and vinyl to be supplied. EFCO will not size for tape glazing
without appropriate information. EFCO will not supply glazing tape or sealant for
tape glazed method. Additional time and cost may be associated with tape glazing.
3. Construction notes
The following practices are recommended for all window installations:
A. Reference Shop Drawings
1. Check the shop drawings and installation instructions to become thoroughly familiar with
the project. The shop drawings take precedence and include specific details for the
project. The installation instructions are general in nature and cover the most common
conditions.
B. Check Openings
1. Make certain that construction which will receive the material is in accordance with the
contract documents. If not, notify the general contractor in writing and resolve
differences before proceeding with your work.
C. Benchmark Layout
1. All work should start from benchmarks and/or column centers lines as established by the
architectural drawings and the general contractor.
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.
