DISCUSSION:
The applicant is requesting approval to replace seven existing vinyl windows with wood
composite windows (Attachment 1). All windows would be the same size, operation, location,
and style with divided lites as the existing windows (Attachments 2 through 5), with the
exception of the kitchen window. The window in the kitchen would be changed from a single-
hung window to a slider. The applicant indicates that the wood composite windows would
preserve the architectural style and historic appearance of the residence.
The Residential Design Guidelines provides the following recommendations related to window
materials:
3.7.3 Match window materials to the architectural style and to the surrounding
neighborhood
• Wood windows are common in Los Gatos. Wood is still the desired choice for styles
that traditionally used wood. However, today there are some window materials, such
as vinyl clad wood windows that are not noticeably different from wood at a short
distance.
4.8.2 Building Materials
• Composite, synthetic, metal, vinyl, plastic or fabricated/ imitation wood products,
painted brick or imitation used brick will generally not be approved. However, some ex-
ceptions may be made on a case-by-case basis when the decision-making body
determines that the replacement is consistent with the appearance of the original
material, and that a lay person would be unlikely to discern the difference. The burden
of proof will reside with the applicant. Material samples, photographs, and specific
locations where the material may be seen in use will all assist in the evaluation of
alternative materials.
4.8.4 Windows and Glass in doors
• Windows should be constructed of real glass, and window frames should be constructed
of real wood - not vinyl, metal, or plastic. Wood sashes may be vinyl or metal clad if the
window frame and dressing is designed consistent with the historic context of the
building.
The proposed wood composite material was not available when the Guidelines were written,
and it is silent on its use. The Guidelines emphasize the use of wood windows but allows
exceptions for alternative materials when they are not noticeably different from wood at a
short distance, found to be consistent with the historic context, and consistent with the

DISCUSSION (continued):
appearance of the original material where it would be unlikely to discern the difference. The
applicant requests approval of the alternative window materials and provided a Letter of
Justification and details on the proposed windows (Attachments 4 and 5).
CONSIDERATIONS:
A. Considerations
Sec. 29.80.290. Standards for review.
In evaluating applications, the deciding body shall consider the architectural style, design,
arrangement, texture, materials and color, and any other pertinent factors. Applications
shall not be granted unless:
In historic districts, the proposed work will neither adversely affect the exterior
architectural characteristics or other features of the property which is the subject of
the application, nor adversely affect its relationship, in terms of harmony and
appropriateness, with its surroundings, including neighboring structures, nor adversely
affect the character, or the historical, architectural or aesthetic interest or value of the
district.
CONCLUSION:
The applicant requests approval to replace seven existing vinyl windows with wood composite
windows (Attachment 1). All windows would be the same size, operation, location, and style
with divided lites as the existing windows, with the exception of the kitchen window. Should
the Committee find merit in the request, the project would be completed with a Building
Permit. The project would not return to the Committee.

February 8, 2023 Historic Preservation Committee (HPC) Town of Los Gatos 110 E. Main Street Los Gatos, CA 95030 Re: Windows Replacement at 248 University Ave / PRE22-01495 To Whom It May Concern:
We would like to kindly request the Committee to grant us approval for the replacement of seven
retrofit windows for the above referenced address. The six vinyl windows to be replaced will be the
same in location, operation and style with full divided lights, and one kitchen window to be replaced
will be from single-hung to glider.
We, at Renewal by Andersen, acknowledge that the window replacement on this dwelling will meet
the requirements for Residential Design Guidelines to improve and enhance the look of the residence,
aside from the energy efficiency they will provide. We assure you our wood composite windows will
preserve the architectural style and historic appearance of the home against what currently exists. Please refer to our window specifications and window brochures for more information and details. Thank you in advance for your consideration. Please do not hesitate to contact me if you need additional clarification. Looking forward to hearing from you.
Best regards,

Energy Efficiency Rating
To help homeowners, in 1992 the National Fenestration Rating Council
(nfrc) established an independent third-party rating, certification,
and labeling program for windows, doors, and skylights (fenestration
products). Renewal by Andersen
displays the nfrc label on all of its
windows. This label means that the
entire window unit has been rated
and certified, not just the center of
the glass or individual components.
See our Energy Efficiency brochure
for additional information.
