The manufacturer is moving from bespoke orders to a standardised product range. Automated production and sales to other window makers support that shift as demand for its glazing systems grows.

Scaling advanced glazing

The product range includes thin-glass insulated units, Winsert secondary glazing and fiberglass and uPVC windows and doors. Production automation supports higher volumes, while engineering and customer support teams help deliver the expanded range.

Selling components beyond its own windows

Third-party sales of insulating glass units supply other North American window and door manufacturers. That channel broadens the use of the technology beyond Alpen-branded systems as the company expands manufacturing capacity.
