Double and triple glazing options are available in widths of 24, 30, 36, 44, and 52 mm, along with slats that facilitate panel utilization. These sections have a low thermal transmittance value (Uf = 0.95 W/m²K) and can accommodate 44 mm triple glass units (Ug = 0.6–0.7 W/m²K). The thermal transmittance value for Pimapen Nirvana series windows fitted with these glass units is Uw = 0.78 W/m²K, offering superior thermal insulation. (*: calculated value).
