Sept 20, 2003Page 1
This section includes factory finished wood window frame intended for Bovard Studios new or restored stained glass and glazing. Frame is for fixed sash and perimeter seal. Stained glass is referenced to Sections 08585 and 08595. Glazing is referenced to Section 08800. Sealants are referenced to Section 07900. If an aluminum frame instead of wood is required, refer to Bovard Sections 08521 or 08522. Air barrier and vapour retarder continuity from wood frame to adjacent construction is critical to successful building air tightness; specify compatible materials in conjunction with Sections 07260 and 07270. This section includes performance, proprietary, and descriptive type specifications. Edit to avoid conflicting requirements.
NOTE: Your suggestions for future revisions to these master specifications are appreciated - please e-mail comments to Ron Bovard at

1.5 SYSTEM DESCRIPTION
Use this article carefully; restrict statements to describe the combined result of the components used to assemble the system. Do not repeat statements made in the Section Includes article. Select one or both of the following two subparagraphs.
.1 Window Frame:
.1 Single thickness wood member for framing glazed lights including stained glass.
.2 Wood frame for:
.1 [outer unit of [glass] [plastic] pane,] [outer insulated sealed unit of two glass panes.]
.2 [stained glass lite,]

1.6 PERFORMANCE REQUIREMENTS
Use this article carefully; restrict statements to identify system performance requirements or function criteria only. Many proprietary window products are marketed without performance data in their literature and therefore may not have been tested for performance characteristics. Consider the potential costs of requiring the following criteria. The following paragraphs represent a suggested listing of performance criteria.
.1 IBC Requirements for Window Assembly and Component Parts: Wind loads, structural member deflection, and hurricane zone and wind generated missile criteria.
.2 Window Assembly Design:
.1 Design and size components to withstand dead loads and live loads caused by positive and negative wind loads acting normal to plane of wall as calculated in accordance with code.
.2 Design and size components to prevent condensation between glass panes, high humidity or high temperature from solar heat gain between glass panes.
Select one of the option subparagraphs depending on the location of the place of the Work.
.3 System Internal Drainage: Drain water entering joints, condensation occurring in glazing channels, or migrating moisture occurring within assembly, by a weep drainage network from interpane spaces and glazing spaces, ventilate through frame not through glazed protective covering:
.1 [Ventilate and drain spaces to the exterior in central and northern climates.]
.2 [Ventilate and drain spaces to the interior in southern climates where cooled air conditioning is used.]
.4 Assembly: To accommodate, without damage to components or deterioration of seals, movement between window, perimeter frame and attachments, deflection of lintel or sill.
Select one or the other (not both) of the following two deflection requirement paragraphs. If choosing the second paragraph below, select only one of the deflection limit ratio subparagraph options.
.5 Deflection:
.1 Limit member deflection to flexure limit of glass of the longer dimension, with full recovery of glazing materials or as required by regulatory code, whichever is more stringent.
.2 Create a glazing space from edge of glass to inside of frame surface, of a dimension greater than maximum deflection anticipated.
The following paragraph identifies an air loss rate that is not usually acceptable in colder climates.
.6 Air Infiltration: Limit air infiltration through assembly to [0.03] [____] L/s/sq m ([0.06] [____] cfm/min/sq ft) of wall area, measured at a reference differential pressure across assembly of [75] [____] Pa ([1.57] [____] psf) as measured in accordance with ASTM E283.
.7 Air and Vapour Seal: Maintain continuous air barrier and vapour retarder throughout assembly, primarily in line with the pane of glass and heel bead of glazing compound, on the warm side of the window assembly.
