RE: New Exterior Wall Header
213 W. Bleeker St.
Aspen, CO 81611
Per your request I have reviewed the framing requirements for a new window in an exterior wall at the
above referenced address. A visual inspection of the proposed window’s location was conducted on
August 18th, 2020 at approximately 2:00 pm. Please see the following for the required new header
specifications for the new window installation.
ENGINEERING DESIGN CRITERIA:
2015 IRC with City of Aspen Amendments
Ground Snow Load – 100 psf
Roof Dead Load – 15 psf
Roof Live Load – 20 psf
Floor Live Load – 40 psf
Walls – 10 psf
Ceiling – 12 psf
Wind Load – 89 mph, Exposure Category B
The proposed window is to be approximately 30” wide and 53” tall and is to be installed in an existing
framed 2”x6” exterior wall. I recommend installing a (3) 2”x8” Douglas-Fir #2 header or better, with
(2) jack studs and (1) king stud on each end. Laminate the header ply’s with ½” OSB as necessary to
establish a 5-1/2” wide header. Verify that the jack studs have solid, continuous bearing to the existing
base plate and foundation. These studs are not to be notched or drilled through.
The existing exterior plywood sheathing is to be cut as needed to form the new window opening.
If the above specifications are followed, the new header will be adequate for the applied loads.
If you have any further questions, feel free to contact me.
With Respect,
