IV 88

IV 88 is a modern system characterized by increased heat absorption and structural stiffness. The increased thickness of the frame allows you to use an energy-saving triple-glazed unit, which until recently was only available in the most expensive windows intended for passive construction.

This solution, combined with the increased thickness of the wooden frame and the innovative window glazing system, allows for very good thermal insulation for the entire window U = 0.93-1.2 W/m2K depending on the selected glazing package.

Technical Characteristics

• wood: meranti, oak, pine
• frame: 88mm
• sash: 88mm, decorative milling
• Max glazing package: up to 52mm
• white or brown foam seals
• heat transfer coefficient Ug 0,5 W/m²K
• waterdrip: aluminum, eliminating cold bridges, and covering the lower stile
• additional seal: improves insulation and sound absorption
• Perfect surface protection thanks to rounded R6 edges (all bevels at an angle of R20°).
