Triple Pane Windows for an Apartment Building — Glass Choices
Tenants on the north side complain about cold rooms and frosted glass every January, and the owner wants to know whether triple-pane is worth it across the building.

Triple pane windows for an apartment building make sense on the coldest elevations and in units with frost and comfort complaints, but not every line offers them. JMB Builders prices dual-pane Low-E and triple-pane on the same opening list, so the owner sees the difference unit by unit, and installs across the Twin Cities metro to St. Cloud. Priced per opening. Photo reply within one business day, or a free walkthrough.
- Priced per opening, dual and triple side by side
- Triple-pane by elevation or whole building
- Only lines that offer it are priced
Triple-pane adds a third pane and a second air space, which keeps the room-side glass warmer. Warmer inside glass means less of the cold draft people feel near a window and less frost on cold nights. Condensation still depends on the humidity tenants keep in the unit, so triple-pane helps but does not cure a wet unit by itself.
Not every line offers it. Among the lines we install: Pella offers optional triple-pane on the 250 Series and, on Impervia, only on awning, casement and picture units. ProVia offers triple-pane ComforTech upgrades on Endure. Andersen offers it on the A-Series and E-Series, and on the 400 Series only in select markets. The Andersen 100 Series and Encompass by Pella are dual-pane only; on those, the Low-E coating does the cold-weather work.
Triple-pane units are heavier and the frames can be deeper, so balances, setting blocks and jamb extensions are checked at the measure. Before we bid, we check the city's contractor licensing and permit rules for that building. On buildings four stories or taller the energy code that applies may differ, and the building official decides.

Situations and options
Dual-pane Low-E everywhere
The base package on every line. A Northern-climate Low-E coating, argon fill and a warm-edge spacer. The coating choice matters more than the pane count on dual-pane-only lines.
Triple-pane on cold elevations
Triple-pane on the north and west sides, dual-pane on the south and east. The bid lists both so the owner can see what the upgrade adds.
Triple-pane whole building
Every opening in triple-pane, on a line that offers it in every style the building needs. Checked against frame depth and sash weight at the measure.
Mixed by style
On lines like Pella Impervia, triple-pane comes only on casement, awning and picture units. Bedrooms in those styles get it; sliders stay dual-pane.
Triple Pane Windows for an Apartment Building — Glass Choices: questions, answered
Are triple pane windows worth it for an apartment building in Minnesota?
They are most useful on north and west elevations and in units with frost or cold-room complaints, because the room-side glass stays warmer. Many owners do triple-pane on those elevations and dual-pane Low-E elsewhere. We price both on the same opening list so the owner decides with numbers in hand.
Which window lines offer triple pane glass?
Among the lines we install, Pella offers it on the 250 Series and on Impervia casement, awning and picture units, ProVia on Endure, and Andersen on the A-Series and E-Series, with the 400 Series in select markets. The Andersen 100 Series and Encompass by Pella are dual-pane only.
Will triple pane windows stop condensation in apartments?
They reduce it, because the inside pane stays warmer, but condensation also depends on humidity in the unit: cooking, showers, drying laundry and how the bathroom fan is used. Triple-pane helps; it does not replace ventilation.
Do triple pane windows fit in our existing window frames?
Sometimes as inserts, sometimes not. Triple-pane frames can be deeper and the sash heavier, so we note frame depth at the measure and build jamb extensions where the new frame sits deeper than the old one.
What Low-E glass should an apartment building get?
A Northern-climate Low-E with argon is the base on most lines, such as Pella AdvancedComfort Low-E, Andersen Low-E4 with the HeatLock coating, or ProVia ComforTech DLA-UV. The exact package is written on the bid by opening.
Do you promise energy savings from triple pane windows?
No. Savings depend on the building, the heating system, the old windows and how tenants live. We give you the NFRC label values for the units being ordered so the owner or an energy auditor can do the math.
