Wooden Windows

Wood Windows
We produce our wood windows in 68mm (2 11/16‘‘), 78mm (3 1/16‘‘), and 90mm (3 9/16‘‘) profile depth. Visible widths can be customized upon request. In the following we will show all cross sections with our IV78 system but can be made with IV68 and IV90.

IV78 Standard

The timber window with aluminum drip sill is our standard product. It excels with excellent thermal performance, as well as air and water tightness. By adapting widths and depths of the profiles the possibilities for customization are nearly endless.

IV78 Historic

Our modern double- or triple glazed windows with historic wood drip sills are mostly used in historic buildings but are also a wonderful option for an all wood window.

Terrace door

Terrace doors operate with a tilt-turn function but have a threshold that ensures a thermal break on the ground level and easy transition from the interior to the exterior.

Bi-Fold Door

Bi-fold doors have the advantage that all sashes can be folded away so that the entire opening can be taken advantage of. As opposed to other sliding door systems there is no fixed sash so the entire element can be folded away.

Lift & Slide Door

Lift and Slide doors often substitute entire walls and offer amazing panoramic views. When open there is a seamless transition from exterior to interior. The mechanism of lifting the active sash allows weights of up to 400kg to be moved with ease.

Double hung with concealed balance

This double hung allows smooth vertical sliding of either sash. An optional tilt-in function for the lower sash allows for ease of cleaning.

Swing and Circle Window

A popular alternative to windows with traditional operating mechanisms are swing or pivot windows.  These windows are particularly suited for unusual mounting situations or in architecturally unique shapes.  For windows in locations that are out of reach, please contact our technical staff to discuss remote mechanical or electrical operation.

Simulated Double Hung

Our Simulated Double Hung mimics the aesthetics of a traditional American double hung while offering the comfort and superior performance of a European tilt-turn window. The upper glass pane is a direct set which also functions as a horizontal post for the lower tilt-turn sash.
Our SDH has been approved by the NYC landmarks council for use in traditional landmark buildings.

European single hung

The European single hung has a movable sash that pivots out from its fixed position and then travels vertically. The secondary sash can also operate with tilt, turn, or tilt-turn function. Extreme ease of operation and very large dimensions are made possible by a counter-weight hidden behind the jamb. Insulating properties match those of European tilt-turns.

Historical double hung

Historic double hung windows utilize the original style pulley, chain and counterweight for sash balance. Recommended when historic authenticity is required.
