Standard double pane vs Passive House triple pane.

Compare a conventional ENERGY STAR double-pane window (24–26 mm) against a 48–56 mm triple-pane Passive House system — tuned to your climate. Every metric, side by side, with the difference made plain.

the difference
How the two systems differ
A third pane, an extra low-E coating and insulating gas change how heat, sun and sound behave at the glass.
2 PANES Double-pane 3 PANES Triple-pane
Heat retention
Extra panes and insulating gas hold interior warmth in — far less heat escapes through the glass.
SUN IN Double-pane REFLECTED Triple-pane
Solar control
Low-E coatings reflect most of the sun's heat back outside instead of letting it into the room.
NOISE IN Double-pane DAMPED Triple-pane
Noise reduction
More mass and asymmetric glass thicknesses absorb outdoor sound, so far less reaches the room.

LuxHaus offers over 400 glass make-ups — combinations of pane counts, low-E coatings, gas fills, laminates, tints and warm-edge spacers — each tuned to a project's climate, orientation, solar exposure and acoustic needs.

This tool is a directional guide intended to help you understand the difference between a standard ENERGY STAR double-pane window and a 48–56 mm triple-pane Passive House system — it is not an exact or guaranteed specification. The values shown are representative and will vary with the specific glass build-up, coatings and gas fill, the frame and spacer, installation quality, window size and orientation, and local climate data; energy-demand figures are indicative annual glazing-attributable savings, not measured results. Because no single comparison can capture all 400-plus build-ups, these numbers should not be used for engineering, code-compliance, energy-modelling or contractual purposes. Your final specification — including U-value, SHGC, acoustic ratings and energy performance — is confirmed per project by a LuxHaus specialist.

About the tool

What Glass IQ does

Glass IQ is an interactive comparison tool that shows how different glass performs — before you request a single quote. Choose your climate, then compare a standard ENERGY STAR double-pane unit (24–26 mm) against a high-performance Passive House triple-pane system (48–56 mm). It visualises the difference across the three jobs your glass does every day.

Heat retention

Extra panes and insulating gas fills hold interior warmth in, so less of it escapes through the glass.

Solar control

Low-E coatings reflect solar energy away instead of letting it bake into the room.

Noise reduction

Multiple panes at asymmetric thicknesses break up sound waves and dampen outside noise.

What you see here is a simplified slice of what’s possible. LuxHaus builds from over 400 glass make-ups — combinations of panes, coatings, gas fills, laminates and warm-edge spacers — each engineered to a specific climate, orientation and acoustic target.

Read it as directional. Glass IQ is built to make the trade-offs intuitive — not to serve as an engineering, code-compliance, energy-modelling or contractual reference. For exact specifications tailored to your project, our team will spec the right make-up with you.
