23 warren windows dec 201923 WARREN STREET, SALEM, MA 01970
The windows are located in the single story kitchen extension at rear of house.
Three sides are exposed to the elements, as well as the roof and unheated basement below,
translating into heating and energy efficiency challenges. The kitchen has two exterior doors,
two casement windows, and two double hung windows, and a basement door, which
exacerbates energy issues. We’ve insulated and upgraded the heating system and are now
working to upgrade windows and doors to tighten the envelope.
These windows are partially visible from a public way from 55 -60 feet away—Warren St.—if
passersby look down the driveway at an angle.
The casement windows were 40+ year old single pane Andersons that had deteriorated greatly.
With Salem Historic Commission approval, we replaced these windows in April 2019 with
Marvin wood casement SDL windows with bronze spacer bars. Draft issues are noticeably
improved.
Now we are turning our attention to the 6/6 double hung windows. They are currently 20+ year
old deteriorating single-pane replacement “barn sash,” that appear to be Brosco. We propose
to replace them with Marvin double hung wood double pane SDL windows to match the specs
of the already approved casements.
We initially priced the JB Sash custom Old Bostonian 6/6 true divided light double hung, which
at $3,037 plus install was cost prohibitive.
The U value of a new Brosco single pane 6/6 window is 0.40, priced at $407 each, plus install.
The U value of a new Marvin window is 0.29, priced at $1,309 each, plus install.
The proposed double hung window specs match the already approved Marvin casement
windows:
Wood painted Benjamin Moore Navajo White to match approved trim of house
SDL with bronze spacer bars and black perimeter
7/8” muntins with ogee profile
Low E1 with argon panes
Half screens in stone white, to match Navajo White, charcoal mesh
(currently screens are a stark white factory finish Harvey storm window)
Exterior casing to be custom built by contractor to match original casing
Interior hardware is oil rubbed bronze
Our contractor for the installation will be John Beardsley of Preservation Carpentry in Andover.
Where it is historically preferable and practical, we have retained the original
historic windows:
In the main house, we are restoring 14 windows with Window Woman of Amesbury in 2019.
(Seven down, seven to go.) We also upgraded to Harvey True Channel storm windows in the
entire house.
In the kitchen extension, we have retained one historic door and added a traditional wood and
glass storm door to improve efficiency (not visible from public way)
The kitchen French door is a 40+ year old double pane, single-light Anderson with interior grid
overlay that has deteriorated greatly. We’ve received a SHC certificate of non -applicability and
are replacing with a Marvin 12-light SDL door, at a higher cost, to match the casements and
double hung windows, even though it is not visible from a public way.
