Featured structural options designed for high-performance architectural projects in Northern Illinois
Chicago and the wider Illinois building environment pose unique challenges for modern fenestration systems. Due to the proximity of Lake Michigan, projects in this region are subject to extreme temperature differentials—plunging below sub-zero during Midwestern winters and climbing above 90°F in summer. Standard exterior doors are prone to thermal bridging, frame warping, and seal failure.
Furthermore, structural engineering in high-rise corridors or windy suburbs requires entrance systems to withstand significant Design Pressure (DP) ratings. Aluminum pivot entrance doors serve as the premium solution for custom residential and luxury commercial properties. Their offset pivot mechanisms distribute weight directly to the floor, enabling massive openings up to 10 feet wide without straining the structural framework.
By incorporating thermal breaks, low-E glazing systems, and heavy-duty multi-point locking systems, Larsom's pivot assemblies are designed to meet Chicago energy code limits and ASCE 7-22 wind load requirements, ensuring ultimate performance without compromising on minimalist design aesthetics.
A look into structural integrity, thermal break barriers, and advanced alloy processing
Utilizing high-tensile 6063-T6 architectural grade extruded aluminum. Frame wall thickness ranges between 2.5mm and 3.0mm, ensuring massive door panels do not warp under heavy cyclic loads.
Equipped with high-performance polyamide (PA66) thermal break bars. This structure reduces thermal conductivity between the exterior frame and interior living space, preventing internal condensation.
Engineered German-design hardware capable of bearing 500kg (1100 lbs) panel weight. Features internal hydraulic self-closing mechanisms, hold-open settings, and adjustable rotation dampers.
