Question 1

What thermal transmittance Uw does the T-Comfort window have?

Accepted Answer

The T-Comfort window achieves a Uw value from 0.84 W/m²K with a Ug 0.7 W/m²K glazing package. The 6-chamber system with a 70 mm frame depth offers very good thermal insulation at an attractive price and meets current thermal requirements.

Question 2

Is T-Comfort suitable for a passive house?

Accepted Answer

T-Comfort with Uw 0.84 W/m²K meets the requirements for energy-efficient construction. For a passive house (required Uw ≤ 0.8 W/m²K) we recommend the T-Perfekt system (Uw 0.69) or T-Energy (Uw 0.57), which thanks to a deeper 82–88 mm profile offer higher insulation performance.

Question 3

How many chambers does the T-Comfort profile have and how does it affect insulation?

Accepted Answer

The T-Comfort profile has 6 chambers. Each chamber forms a separate air space acting as a thermal barrier. The 70 mm frame is available in many variants: standard, renovation (30/52/65 mm), monoblock (ISO 100–160 mm) and Swiss variant.

Question 4

How does T-Comfort differ from T-Classic?

Accepted Answer

T-Classic has 7 chambers and Uw 0.84 W/m²K — same Uw as T-Comfort, but more chambers. T-Classic is a more versatile system with a wider choice of frame variants. Both systems use a 70 mm frame depth and support aluminium overlays.

Question 5

What is the acoustic insulation of T-Comfort?

Accepted Answer

T-Comfort offers acoustic insulation Rw up to 45 dB, meaning effective reduction of noise from a busy street, an airport or a railway line. A 45 dB reduction brings a loud conversation in front of the window (70 dB) down to the level of a whisper (25 dB).

Question 6

Which colours are available for T-Comfort windows?

Accepted Answer

T-Comfort is available in 15 colours: Cream white, Anthracite structured, Anthracite smooth, Walnut, Golden oak, Whitened oak, Honey oak, Silver grey, Starry basalt, Black smooth, Norman oak, Douglas, Polish pine, Walnut and Vintage pine. All colours are available on both sides.

Question 7

What anti-burglary class does T-Comfort have?

Accepted Answer

T-Comfort has anti-burglary class RC2 according to EN 1627. It means the window withstands burglary attempts with simple tools (screwdriver, pliers, wedge) for at least 3 minutes. Class RC2 is recommended by police for residential buildings.
