Swiss products with patented design

Air-lux provides a truly unique patented sealing system for residential and commercial projects alike. The air-assisted ring seal along the perimeter of each unit creates an impermeable barrier when inflated, and retracts within the frame when open for a clean appearance -no need for lips or brushes. The result is a reliable performance product made for panoramic views.

Retractable Units

Air-lux Technik AG, born from Krapf AG in 2004, is a dedicated team based in Engelburg, Switzerland. Their specialty is glass façade construction and massive retractable units, built not only for residential homes, but also commercial properties.

Product Types

Minimalistic home interior with expansive sliding window open to private pool.

Sliding Windows

With the ability to cover openings as large as 25 m² (~270 ft²), these sliding units deliver a sleek aesthetic with quality function. The robust, single-track system is installed flush, the sash running on the outside, resulting in the appearance of an essentially frameless window. Coupled with a smooth and quiet operation, this solution is perfect for large glass designs.

Descending Windows

For a more dramatic entrance and operation, our partner, Air-lux, is a master of descending units. Available in sizes to suit the maximum glass dimensions available (3.6m x 16m for specialty), this product is also equipped with top-of-line security packages and custom finishes. All mechanical elements are stored below-ground, concealed in the same accessible space the units descend when open.

Pivot Doors

Equally impressive for a large entrance, Air-lux pivot doors are perfectly balanced for weightless operation. With two inflatable gasket plains on pivot sashes, this product has exceptional performance for a pivot door. Units also include electro-mechanical locking bolts which can be operated via third party accessory key fobs, scanners or access codes
