Introducing Reynaers SL68 Casement Window System: Combining Minimalist Aesthetics and High Performance

In today’s contemporary architectural design, the Reynaers SL68 casement window system has proven to be an industry standout. Known for their ultra-slim yet robust aluminium profiles, these outward-opening windows deliver a superb balance of elegance and performance, making them ideal for both renovations and new installations.

Their slimline profiles not only retain the original daylight, but also enhance weather resistance and insulation. Additionally, their SBD and PAS24 ratings ensure maximum safety and security.

What sets the SL68 system apart is its impressive performance data. With thermal insulation Uw at 1.1 W/m²K, it is among the top performers in energy efficiency. Comfort is prioritised with class 4 (600Pa) air tightness, E1200 (1200Pa) water tightness, and C5 (2000Pa) wind load resistance. Opening and closing resistance is classified at Class 3, while PAS 24 is the standing burglar resistance rating.

The system also boasts flexibility in dimensions, accommodating a maximum vent weight of 110 lbs, and a profile design slope of 25 degrees. The glazing aspect of the SL68 is equally impressive, with an 18 mm rebate height and options for dry and internal glazing.

The Reynaers SL68 Casement Window System underscores that luxury, sustainability, and high functionality can indeed coexist, and it is leading the way in aluminium window design.
