A bright window with Active TT film - a view through clear glass with no mirror effect
/ IzolGlass · windows without replacement

Don't replace your windows. Change what the glass does.

A thin Active TT film applied to the glass you already have. In summer it reflects the heat, blocks over 99% of UV rays, and the window stays bright. No new frames and no renovation.

Glazing is the thermally weakest part of a building. In summer it lets the heat in and the interior overheats; UV rays damage furniture and carpets. Replacing windows is a big cost and weeks of renovation. IzolGlass changes the parameters of the glass you already have:

In summer
reflects infrared before it heats the interior
UV protection
blocks over 99% - furniture and carpets do not fade
No replacement
applied to the existing window, in a single day

One film, two variants - plus a panel.

Active TT film in two variants, selected by window exposure during the audit, and where the film does not work - IzolGlass Panel.

01 / Active TT Południe

Active TT Południe

Film for windows facing the sun (S, SE, SW).

  • For vertical windows facing the sun.
  • Reflects infrared before it heats the interior.
  • Blocks over 99% of UV rays.
Parameter Value
Infrared reflection (IR) >92% Active TT datasheet
UV protection >99% Active TT datasheet
Visible light transmission (VLT) 70% Active TT datasheet
Solar energy rejection (TSER) 81% Active TT datasheet
02 / Active TT Północ

Active TT Północ

A universal film, also for skylights and roof windows.

  • Universal across any exposure.
  • Dedicated to skylights and roof windows.
  • Blocks over 99% of UV rays.
Parameter Value
Infrared reflection (IR) >60% Active TT datasheet
UV protection >99% Active TT datasheet
Visible light transmission (VLT) 72% Active TT datasheet
Solar energy rejection (TSER) 59% Active TT datasheet
03 / IzolGlass Panel
Launch Q3 2026

IzolGlass Panel

A panel for windows where the film does not work (single-pane, low-emissivity).

  • For single-pane and low-emissivity windows where the film does not work.
  • Fitted frame on frame, like a mosquito net - without replacing the window.
  • An effect close to a triple-pane window.

Replace the windows or IzolGlass?

The same goal - warmer and no overheating. Two completely different roads.

IzolGlass film on existing glass
Window replacement new frames
Cost indicative, per m² of glass
IzolGlass film on existing glass from ~300 PLN/m²
Window replacement new frames 2,000-4,000 PLN/m²
Time typical site
IzolGlass film on existing glass a single day (30-40 m²)
Window replacement new frames weeks
Renovation, noise, rubble scope
IzolGlass film on existing glass none
Window replacement new frames full
Need to move out during the work
IzolGlass film on existing glass no
Window replacement new frames often yes
Reversible can it be undone
IzolGlass film on existing glass yes
Window replacement new frames no

Indicative prices, depending on the condition and type of glass - the window audit gives the exact figure. IzolGlass works on technically sound insulated glass units; for single-pane and low-emissivity windows, IzolGlass Panel is often the right direction.

Where IzolGlass works best.

Pick your case - we'll select the Active TT variant after the window audit.

What to expect
Step
/ House

A house with large windows or a glazed living room

In summer the living room or attic is unbearable and the air conditioning cannot keep up.

Active TT Południe on the windows facing the sun.

Manor house in Nadułki: 5-6°C cooler in summer in the rooms with the film.

/ Office

An office building or storefront

A glass facade overheats the interior and the air conditioning runs flat out.

Active TT - variant selection based on facade exposure.

Less overheating and relieved air conditioning, without replacing the glass units.

Active TT datasheet

/ Public

School, kindergarten, practice

Rooms overheat in summer, and a renovation around children and patients is impossible.

Film applied in a single day, with no wet work.

Room comfort without shutting down the facility and without demolition.

/ Heritage

A heritage or protected building

The conservator will not allow new frames, and the windows lose heat.

The film does not change the look of the window and is reversible.

Improved parameters without interfering with the historic frames.

variant selection procedure

/ Proof from the site

The film is applied to existing glass - 30-40 m² a day, with no renovation.

Frequently asked questions.

Six things people ask about most - before the film goes on the window.

01 01

Will the room get dark?

No. The film transmits 70-72% of visible light (VLT) - the window stays bright. The coating works in the infrared and UV bands, not by tinting.

Active TT datasheet

02 02

Will the film or a mirror effect be visible from outside?

No. Active TT is a nanocoating, not sputtered metal - it creates no mirror effect, either from the inside or the outside.

Active TT datasheet

03 03

Will furniture and carpets fade?

The film blocks over 99% of UV radiation - it is UV that fades fabrics, furniture, and finishes.

Active TT datasheet

04 04

Can I remove it later?

Yes. The application is reversible - the film can be removed without replacing the glass.

IzolGlass product card

05 05

Will the glass crack?

Every installation is preceded by a window audit: assessment of the unit type, edge condition, exposure, and frames. The application is carried out only by certified crews.

Variant selection procedure

06 06

How long does it last?

Durability of 5-10 years outdoors, with a 5-year warranty. The film contains no metals that oxidize over time.

/ What it looks like

Three steps, one day on site.

A calm process - from measurement to warranty.

  1. Free window audit

    We come over, measure the glass, and assess the unit, exposure, and frames. We select the variant and show you what to expect. No obligation.

    free of charge
  2. Application in a single day

    The film is applied to existing glass using the wet method. A two-person crew covers 30-40 m² a day. No demolition, no rubble, no moving out.

    30-40 m²/day
  3. Report and warranty

    Measurement after application, a product card, and a 5-year warranty. The room is fully ready 24 h after installation; no window cleaning for the first 30 days.

    5-year warranty

Check your windows. No obligation.

We'll measure the glass, assess the exposure, and select the Active TT variant. We'll show you what to expect. The audit is free.

Indicative values. The audit gives concrete numbers for your windows.
