Gable Units Attached Between a Flat/Sunroof Unit & an Existing Structure
Gable Units which are attached between a Flat/Sunroof Unit (excluding pergolas) and an existing house, shall only be considered attached if the Gable Unit is attached to the existing house (C) for its full length (L) and the longest side of the combined unit (B) does not exceed twice the gable length (L). The Flat/Sunroof Unit in this case can be considered attached. This style requires all coloumns to be embedded into footings.
Gable Units Attached to Flat/sunroof Unit One or Both Sides
Gable Units which are attached one or both sides to Flat/Sunroof Units, (excluding pergolas) must be attached to an existing house for at least 75% of the gable opening length (O) to be considered attached. Flat/Sunroof Unit/s must be deemed attached as detailed in the Flat/Sunroof Unit section below to allow the Gable Unit to be considered attached.
Gable Units are considered attached both sides if both Flat/Sunroof 1 and 2 comply with attachment rules for Flat/Sunroof Units as detailed below. Gable Units are considered attached one side if only one Flat/Sunroof Unit exists and it complies with the attachment rules for Flat/Sunroof Units as detailed below.
When designing an Outback, consideration should be given to both Roof sheet direction, and the orientation of any openings and overhangs involved. These are often determined by appearence and drainage requirements. The following charts show some of the normal options used, but contact Stratco if assistance is required.
