Window construction
High-quality windows need reliable plastic profiles. Heller Kunststoffe manufactures mounting rails, distance profiles and sealing profiles for window construction: custom extruded, as fixed lengths or rolls, in use worldwide for decades.
WINDOW PROFILE UNDER WATER SPRAY
Tight when it matters
Driving rain and pressure difference
A window profile separates inside from outside: it has to drain water, resist wind and stay elastic for years.
The right hardness in the right place
Load-bearing areas need rigidity, sealing areas need conformability. Dual-hardness co-extrusion unites both in a single profile.

How your profile is madeFAQ: Window construction profiles
Which profiles does Heller manufacture for window construction?
Our extruded profiles serve as mounting rails, distance profiles and sealing profiles in window systems worldwide, each custom-made for your system.
Can sealing profiles be co-extruded as dual-hardness compounds?
Yes. Co-extrusion joins a rigid carrier and a soft sealing lip in one profile, a proven design for window seals. More in manufacturing.
Does Heller deliver fixed lengths or rolls?
Both. Mounting rails and distance profiles typically come as fixed lengths, sealing profiles on rolls for continuous processing on request.
How fast can I get a sample of my window profile?
After the extrusion tool is completed we provide samples for trials and tests; after your approval, series production starts promptly. See toolmaking for the process.
