Hidden opening sashes for glass facades and portals: the vent leaf sits flush in the glazed plane, so a panoramic facade also airs the house without a single visible frame breaking the picture. Selected and fitted by the studio.
From outside you cannot tell which pane opens: the vent sash repeats the sightlines of the fixed glazing exactly. From inside it tilts or turns to bring in the garden air without a draught across the room.
This is the detail that keeps a glazed house healthy. A sealed panoramic facade or a winter garden under a glass roof heats up and holds moisture; a hidden vent sash lets it breathe without a visible frame breaking the picture.
We engineer the sashes together with the facade or portal — matched profiles, concealed warm hardware, the same glass — so ventilation is felt, not seen.
Why order it through the studio
Invisible by design
The vent sash is matched to the facade sightlines so it disappears — ventilation without a frame breaking the glazed plane.
Studio price and own production
A direct contract with the partner’s workshop gives price, lead time and warm hardware the open market will not offer.
One responsibility
The sashes are engineered together with the facade or portal — one contractor answers for the whole glazed wall.
Where glass breathes
Winter gardens and sealed facades
The more glass a house has, the more it needs to breathe. A winter garden under a glass roof, a panoramic living room, a portal wall — each traps heat and moisture, and each stays comfortable only with ventilation you never notice. We hide the opening leaves in the glazed plane and let the house air itself.
