Early-stage technical engagement that saves time and rework
Specifiers working with Schlegel at the design stage benefit from direct access to product engineers who can advise on seal selection, dimensional requirements and performance criteria before specifications are finalised. Engaging early reduces the risk of costly redesigns, helps confirm compliance with standards, and ensures the right Q-LON or extruded seal product is matched to your application from the outset.
Custom seal design for exacting specifications
Where standard products do not meet your project requirements, Schlegel’s engineered solutions service delivers bespoke seal profiles and gaskets designed to your exact dimensions and performance targets. This service supports specifiers across windows and doors, insulated wall panels, glazed partitions, HVAC systems and vehicle glazing, with Schlegel manufacturing to your defined requirements.
