Latest evolution within the exceptional Practic casement system series.
Building on the outstanding mechanical qualities of its smaller sibling, the Practic 65 RPT, it incorporates two working reinforcements: one on the exterior profiles and another on the interior ones. It is available in two versions: European Groove and 16 mm Groove.
The system innovation is the introduction of 39 mm polyamides with internal chambers. This system is recommended for heavy or large glass panels and is especially suitable for climatic zones with significant thermal fluctuations, where achieving top-tier energy savings is a priority both energetically and environmentally.
Casement window with European groove with thermal break (RPT), frame of 80 mm and sash of 87 mm.
The innovation of this system is the introduction of 39 mm polyamides with internal chambers. The sash polyamide is made with a new low conductivity material called “low lambda.” Additionally, it features two central seals: one for watertightness and another for thermal and acoustic insulation. The entire assembly achieves an outstanding frame thermal transmittance value of 1.5 W/m²K, an exceptional coefficient without doubt.
Test bench performance results are as follows:
The frame profiles include a clipping system that allows easy placement of auxiliary profiles such as cover trims, drip edges, or frame joints.
Innaltech supplies the complete range of accessories for this system. All our systems are fully integrated with software for material breakdown, cutting optimization, manufacturing sheets, and CE marking labels. Additionally, automation of cutting and machining on CNC centers is possible. The software is available in Spanish, Catalan, and French.
