ROESE (pronounced “rose”)
Rough Opening Extension Support Element
A ROESE is a projection (bump-out) or extension to the structural wall framing at the rough opening perimeter.
Functions: (1) support the weight of the window (2) allow direct structural attachment of the window in order to transfer wind loads to the structure (3) enable window alignment with the exterior plane of the FPIS for proper integration with cladding and/or WRB.
“A ROESE must consist of a material and fastening method capable of maintaining structural continuity between the framing and the window. Traditionally, that material has been wood.”
-ROESE Task Force
The use of a ROESE is recommended by FMA/AAMA/WDMA Standard 500-16
“Standard Practice for the Installation of Mounting Flange Windows into Walls Utilizing Foam Plastic Insulating Sheathing (FPIS) with a Separate Water-Resistive Barrier (WRB).”

In August, 2016, the joint FMA, AAMA, and WDMA Installation Committee developed this industry standard guide for the installation of windows & doors.
The committee recommended use of a ROESE when installing nail flange windows with foam.
These standards are developed by industry experts for window & door manufacturers to assist in developing their own product installation guides.

The term ROESE was developed by a joint committee of the AAMA, WDMA & FMA.
The purpose of the ROESE task force is to create a Standard Practice for the Installation of Mounting Flange Windows into Walls Utilizing Foam Plastic Insulating Sheathing (FPIS) with a Separate Water Resistant Barrier (WRB).
Two new Task Groups were created by the Wall Interface Council at the AAMA Annual Conference in February 2015.
Rough openings have changed due to several factors.
The key is “environmental separation technology,” which focuses on control layers to keep interiors apart from the exterior and integrate them with the fenestration. Air control works to minimize infiltration/exfiltration, which acts as a delivery vehicle for moisture in bulk and vapor form. Moisture control minimizes bulk water infiltration or condensation. Thermal control addresses thermal transmission and thermal bridging.
