ASSEMBLY DESIGN CONCEPTS & IDEAS
A study of the elegant and time-honored building details found in classical European architecture reveals a careful attention to mathematical proportions. Because of the significant expense required to adorn modern buildings with materials of appropriate scale and detail, such masterful craftsmanship has all but disappeared from modern design. PW’s technologies, however, now make such architectural sophistication a practical and affordable alternative for the modern builder.
DOOR & WINDOW PROFILE PROPORTIONS
Stanndard windows on a typical modern home are generally enhanced with PW casings 4”-6” in width, with sills of similar proportion.
Larger-scale homes, feature windows and doors, and key passageway opennings typically benefit by using PW casings 6”-9” in width, or even larger for more massive structres. PW sills and headers are available to complement any degree of casing upsizing.
For an even more elegant appearance, PW headers, corbels, keystones and arch tops might also be worth of your design consideration.
REMEMBER. Each PW shape is elegantly designed, but careful attention should be made to ensure each component of the overall assembly is in proportion to the whole. The same guidline should be followed when adding bases, mid-bands, cornices and other features.
DOOR & WINDOW SYSTEMS
The header (a combined crown and spacer) typically ranges in width from equal to the casing to double the casing width.
Sills are generally slightly wider than the casings they support.
The outside casing edge should not align beyond the extreme flat top edge of the sill.
To visualize a doorway, simply block of the sill profile.
TYPICAL ARCHED OPENING
A classical arch is a true ½ circle.
The arch base (known as the “spring point”) should begin at the centerline of the doorway and transom intersection.
Keystones should protrude slightly below the arched casing’s interior peak and project a greater amount above the highest elevation.
