/ IzolPanel in one paragraph

IzolPanel is the third product of the IzolGlass line. Not a film, not a glazing unit: a panel with an Active TT nano-coating in a frame, mounted mechanically on the existing window sash - like an insect screen, without removal, without drilling. It works where film does not: on single-pane, low-emissivity, triple-pane and special windows. Commercial launch autumn 2026 - currently a reference pilot.

/ How the panel mounts

Frame to frame. Like a mosquito net.

The Active TT panel is fixed mechanically onto the existing window sash - frame to frame, without drilling and without removing the glass. A sealed air layer forms between the panel and the window: a third-pane effect that improves Ug and Uw. The window stays in place.

Mounting the IzolPanel frame to frame on an existing window Horizontal cross-section of a window. The exterior zone (outside) is on the left, the interior on the right. A framed Active TT panel is added to the existing double glazing, fixed mechanically frame to frame. A sealed air layer forms between the panel and the window - a third-pane effect - improving the Ug and Uw values.

/ Status

The road to the Q3 2026 commercial launch.

Technical parameters are declared and pending confirmation in Q3 2026 tests.

  1. Certification tests for declared parameters

    IR blocking, UV blocking, VLT, Ug improvement, Uw improvement and declared target cost below PLN 300/m² will be confirmed or corrected after tests.

    Declared parameters - Q3 2026 tests

  2. Pilot for 3-5 reference buildings

    Priority: heritage, office and school buildings. The goal is before and after measurement plus seasonal mounting mode validation.

    Q3 2026 pilot plan

  3. IzolPanel commercial launch

    Commercial launch is planned after the pilot and confirmation of declared parameters.

/ When film, when panel, when replacement

Three routes to a better window.

Film works on serviceable double-glazed units. The panel - where film does not work. Window replacement - a last resort.

/ Deployment mechanism

The panel is designed for windows you do not want to replace.

Mounting, fit and seasonal use follow one principle: the existing window stays in place.

/ 01

Mechanical frame-to-frame mounting

The panel is mounted mechanically on the existing window sash, frame-to-frame. No drilling, no metalwork and no glass removal. Declared installation time is 2-4 minutes per window, pending Q3 2026 pilot confirmation.

2-4 min declared installation, Q3 2026 tests frame-to-frame mechanical mounting

Where film does not work

The scope includes single-pane, low-E, triple-pane, armoured and special glass. The panel is a separate framed element, so it does not require direct application to the glass surface.

Seasonal mode

The same operating logic supports two seasonal scenarios: interior-mounted in winter and exterior-mounted in summer. The mounting side will be validated in the reference pilot.

winter interior-mounted summer exterior-mounted

Seasonal mode - Q3 2026 pilot

/ Window stock

Around 110 million windows in Poland are below current thermal standards - IzolPanel is designed for buildings where full replacement is not the first decision.
