Frequently asked questions

Why does NIPROM recommend wooden windows?

According to NIPROM, wooden windows keep the warmth in the home and let the sun in but not the heat, last a long time and keep their shape despite outdoor humidity and heat. Because they can be painted, their life is extended and they fit different spaces and styles.

How energy-efficient are your wooden windows?

The tested single-sash wooden window, 800 × 1400 mm with a 68 mm wood profile and argon-filled glazing, reached U = 1.0 W/m²K and air permeability class 4 (test certificate 0054/2025, UKIM). The U-value of your window depends on its size and glazing, so we state it in the offer.
