Mid-Century Ranch, Aluminum Jalousie Frames

Jalousie windows — beautiful, terrible. Every gap in those louvers was a direct line to outside. Condensation was pooling on the sills every morning from October through April.

Three problems,
one solution.

first-season savings
01

Suburban Homeowners

Your heating bill climbed 40% in two winters.

You've added insulation, replaced the furnace, even switched providers — and the bill still went up. The culprit is standing right in front of you. Single-pane frames from the Nixon era are bleeding conditioned air every hour you're at work.

Property Managers

Tenant complaints about drafts are a maintenance budget drain.

A single-unit draft complaint costs $180 in staff time and parts before anyone fixes anything. Multiply that across a twelve-unit building in February. One Pane installation visit eliminates the cycle — sealed units, zero re-calls, tenants who renew.

Portfolio clients average 3.2 fewer maintenance calls per unit per winter.

"We had three different insulation contractors out here. None of them found it. Pane showed up with a thermal camera, pointed at the north windows, and said 'there's your problem.' First winter after install, our heating bill dropped $580. I wish we'd called them two years earlier."

"I manage 34 units across four buildings in Somerville. Draft complaints were my single biggest maintenance cost in winter — $200 a call, sometimes twice a month per unit. After Pane worked through Building C, I had zero draft calls that winter. Zero. We're doing the other three buildings this fall."

"The Landmarks Commission had rejected two previous contractors' proposals for our building. Pane submitted an interior-mount spec on a Tuesday. We had approval by Thursday. They understand the preservation requirements in a way that most window companies simply don't."

"My husband kept saying we should just replace the whole window. I'm glad I pushed back. Pane's storm system cost a third of replacement and we got 90% of the performance. The condensation on the bedroom sills is gone. That alone was worth it."
