The bay windows at Montrose St. were a source of enormous heat loss. With 3 exposed facades, the corner property is very uncomfortable in winter. Together with Duffy/Sabra architecture, MNB Constuucts renovated the bay windows utilizing a rain screen methodology and thermally insulating from the outside.
Here is the Process
The existing siding and sheathing was stripped to the studs
Fiberglass batt insulation and new 3/4″ plywood sheathing installed
Self adhering waterproofing membrane is then installed
2″ rigid insulation board and furring strips installed over membrane
Mesh vents i(Cobra Vent) installed between furring
Insect screening is installed at vent area
Cement fiber board siding installed to furring strips
PVC Trim boards added over base flashing to conceal rain screen vents from bottom view
Bays Finished in a bright Blue Duration Paint.
