Description
Vinyl-Aluminium window frame, insulated by EPS, 0.031 and 0.041 W/(mK). Allowed sesh-dimensions e.g. 1.0 *2.5 m or 1.5 * 1.5 m, white or IR-reflex-coloured. Airtightness: Q100 = 0.16 m³/(hm), determined for a tilt&turn-window 1.6 * 1.6 m. At the threshold, the dew-point crterion is achieved when installed. At the flying mullion and at the wide mullion, the temperature factor is smaller 0.7. Pane thickness: 44 mm (4/16/4/16/4), rebate depth: 19 mm. Spacer: SuperSpacer Tri-Seal.
