Clear Opening Dimensions
Definitions of Acceptable Emergency Escape & Rescue Openings: “Egress” has long been the term used to describe the clear opening dimensions of a window or door necessary to enter or exit a building in case of an emergency. With the release of the International Building Code (IBC) and International Residential Code (IRC), “egress” is no longer the appropriate term. IBC and IRC have set the following as basic requirements for Emergency Escape & Rescue Openings. Because every installation is different, Kolbe strongly recommends consultation with the local supplier or an experienced contractor, architect or structural engineer prior to the installation of any Kolbe product. Installation of Kolbe products, including sizing of rough opening, method of attachment, fastener selection, and code compliance is the sole responsibility of the architect, building owner, contractor and/or consumer. Unless otherwise specified, if units are ordered by rough opening, Kolbe will size the units using our standard minimum 1/4" gap - regardless of the options or construction of the product ordered. Rough Opening Recommendations: The Kolbe standard rough opening dimensions published in our product literature are provided as a guideline to maintain a minimum 1/4" space between the window or patio door and the building structure. There are certain situations where Kolbe recommends a gap larger than our published 1/4" standard: } When installation clips are used, the gap should be increased to 1/2" on the sides, top and bottom of the unit. } When mulls are installed in the opening, the gap all around should be increased to 1/2". For installation consistency, the same gap should be used on all units in the project. } Kolbe recommends using a sill pan drainage system, and increasing the gap to 1/2" on the top and bottom of the unit.

Notes For Casement Windows: } Clear opening widths shown are for standard casements with multi- point locks and concealed hinges. } Exposed Hinges (a.k.a. Euro Hinges) - The Euro hinge is the default hinge used when standard concealed casement hinges can not be utilized (radius head units, high performance units and impact performance units), or if this type of hinge is requested. } In most cases single-arm operators are used with Euro hinges, which changes the clear opening widths. For units with this type of hinge, add 3-7/16" to widths shown for one sash open. For French casements add 6-7/8" to widths shown for two sash open. Two sash open may or may not be considered as an acceptable emergency escape and rescue opening per the local building inspector. } All dimensions are taken with sash open to 90°, except for an “E” Series unit with dual-arm operator and concealed hinges, which opens to 75°.
