SunClad™ products can be mulled together to form special feature windows or window and door combinations. These configurations can be as simple as combining two units together, side by side, or as complex as combining multiple units of various styles and shapes to form a special feature window wall. Send us your ideas and we will help you configure your special combination.
The maximum over-all size for a factory mulled unit cannot exceed 12' by 8' (vertical or horizontal).
Maximum units wide = 5
Maximum units high = 4
Maximum Door Mulled Unit = 6-0 x 6-8 with Call Height 12 Transom
No units can be mulled to the sides of True French Doors. Use separate framing.
When mulling SunClad products together, the over-all unit size can be determined by adding the product unit sizes together. For combinations of 3 units or more, an incidental gain may occur. Increase the Rough Opening dimension by 1/8" for 3 units or 3/16" for four units.
Exterior Mull Covers are included and installed on factory mulled units.
Mull Covers for mulling products on the job site are also available.
