Historic-district commission continues hearing on 3 replacement windows at 181 Dutton Road

The Sudbury Historic Districts Commission on March 6 continued a public hearing on a request to replace three windows at 181 Dutton Road, citing concern that the proposed composite windows and the vendor’s installation method would not replicate the appearance of historic wood windows.

The applicants — Renewal by Andersen representative Nico Spadoccia and owner Gary Christelos — asked for a certificate of appropriateness to replace three failed windows in a one-level addition that faces Dutton Road. Christelos told the commission the windows date to an addition installed in the early 1990s and are “viewable from the road. So, that's why we're seeking approval of the historic district's commission.”

Commissioners praised aspects of the submission (like full-frame installation to preserve original glass and exterior-applied grids) but repeatedly questioned the use of a wood-fiber composite (marketed as Fibrex by the vendor) instead of a true wood sash and the way the composite frame would sit relative to exterior trim. Commissioner Anu Shah said replacing a historic wood window with composite “is my concern,” noting she could not recall the commission approving composite windows on older houses in the district. Commissioner Chris Hacker and Commissioner Pete Davinella echoed that the house is historically significant and said the visible installation details matter as much as material.

Renewal by Andersen's representative described the product as a 40% wood-fiber polymer composite with exterior-applied grids, a half-inch grid profile (with larger sizes available), an exterior detail that the company said can be painted, and a U-factor meeting code at 0.3. Spadoccia showed section drawings and an installed-photo example on screen; he said the units would be full-frame installations intended to preserve existing glass and allow replacement of exterior trim.

Commission discussion focused less on energy ratings than on visual detail: commissioners said composite frames often present a different profile from historic wood sashes (with the frame appearing more exposed and the trim butting to the frame rather than overlapping it). Davinella, who said he lives on Dutton Road and called the house “one of my favorite houses on the road,” said he believed wood should be used for windows on the road-facing elevations. Christelos said he had previously received mixed approvals: the historic front windows were replaced with wood, while non-road-facing windows were allowed to be aluminum-clad when the owners replaced windows earlier, partly for cost reasons.

After extended discussion and review of on-screen samples, the commission agreed to continue the public hearing so the applicant can pursue alternatives. The commission indicated it will look for either a wood product or changed installation/details that make the sash-and-trim relationship read like traditional wood windows. The commission continued case 25-07181 (181 Dutton Road) to the April 3 meeting by unanimous vote.

The decision was procedural only; no certificate of appropriateness was granted or denied at the March 6 meeting. The applicant said he will confer with the vendor to determine whether a different installation detail or a different manufacturer is feasible and will return with revised specifications or samples.

Why it matters: the three windows are visible from a public way and are part of a property the owner described as historically associated with the Wayside Inn campus. Commission members said their concern is both material authenticity and how installation details change the visual relationship between sash and trim, an element they said is important to preserving the house’s historic character.

What’s next: The public hearing was continued to the commission's April 3 meeting. The applicant may submit modified specifications or samples before that meeting; the commission advised that a different manufacturer or a revised installation detail would not require a new application, only a modification to the pending case.
