Aluminium curtain walls in Batumi: staircases, entrance screens, shopfronts

Aluminium curtain walls in Batumi: where they are needed

A curtain wall is a glass wall on an aluminium frame of mullions and transoms that closes an opening taller than a storey or wider than an ordinary window. We install aluminium curtain walls in Batumi on the staircases of private houses, in double-height living rooms, on entrance screens, in shop and cafe fronts and in glazed links between buildings. Unlike a window, a curtain wall carries the wind on its own frame, and its glass can be fixed, opening and door panels in one system. If glass covers the whole facade of a building, that is facade glazing, with its own details at the floor slabs.

A curtain wall for a staircase or double-height room

A staircase with a two-storey glass wall makes the house bright and gives a view with every step. Here the curtain wall is fixed to the floor slabs and wall ends, and the transoms are set at the heights of steps and landings so they do not cut across the view at eye level. The lower panes at landings are laminated, and if the glass is lower than the balustrade, we add an inner guard. The staircase itself is designed together with the curtain wall, as described on the staircases page.

Entrance screens and shopfronts

An entrance screen includes a door in the same aluminium system, side panels and a top light over the door. For a private house we use a thermally broken profile and a door with a thermal break, multipoint lock and closer. For a shop or cafe the front must be strong and clearly visible from the street: we fit laminated glass that does not shatter when struck, and a panic exit door if the design requires it. How we build retail premises is described on the shops and retail pavilions page.

• one profile colour for the windows, doors and curtain walls of the building;
• a canopy or overhang above the entrance door so rain does not hit the threshold;
• a drainage channel in front of the threshold;
• lock, closer and door stay designed for wind off the sea.

Wind, sun and earthquakes

A tall curtain wall catches the wind like a sail. We size the mullions and the fixing centres for wind load and height, and make the fixings to the floor slabs with movement so the building frame can shift in an earthquake without loading the glass. A curtain wall facing south or west without solar control glass overheats the staircase and hall, so on those sides we use multifunctional glass or fit external louvres. Over the entrance we suggest a glass canopy, described on the glass canopies page.

Installation and maintenance

The curtain wall frame goes in once the openings and floor levels are ready, then it is glazed and closed with pressure plates and decorative caps. Junctions with the wall are sealed with tapes, and the bottom transom drains to the outside. Maintenance means an annual check of seals and drainage, door and closer adjustment and, by the sea, rinsing the profile of salt.
