What is Curtain Walling?
Curtain Walling is a non-load bearing glazing system which is generally hung on a buildings structure (hence the curtain reference), but can also be dead loaded. Curtain walling is generally constructed out of aluminium framework & glass and forms an integral part of a buildings envelope.
There are a number of factors that must be taken into account during curtain wall design including; weather tightness (air permeability, water tightness, wind resistance), acoustic requirements, thermal performance, solar shading, and ventilation.
Curtain walling is usually characterised by a square or rectangular grid of mullions and transoms, however designs can be further enhanced to incorporate facets, curves and sloped roofs. Curtain wall facades can also incorporate a variety of inserts including; Windows (parallel opening vents, concealed vents, tilt & turn, pivots, top/side hung), photo voltaic panels and Doors.
The curtain wall facades aesthetic appearance can be manipulated to offer a flush appearance with the exclusion of face caps (SSG), or can be given enhanced vertical or horizontal emphasis using a Trame/Aerofoil face cap (please see below).

Visible Grid Curtain Wall
Dortech are approved fabricators of Schuco, Technal and Senior Architectural Systems Curtain Wall Systems. Each suppliers visible grid curtain wall suite works around three basic elements:
1) A back box which determines the rigidity and structural span capabilties,
2) A pressure Plate which is mechanicaly tensioned to retain the glass and
3) A face cap to give a neat external finish.
The curtain wall face caps are available in variety of different designs. Most commonly they are supplied with a square or 'aerofoil' type design.

Trame Curtain Wall
Dortechs Trame curtain wall systems can be applied vertically or horizontally. The systems are generally specified when building designers wish to create enhanced vertical or horizontal emphasis in a curtain wall screen.
Trame Horizontale: An ‘aerofoil’ external face cap is applied to all horizontal sections of the curtain wall screen. This cap generally extends 80mm out from the glass face. Further extension is made possible with extension pieces. Vertically, the face caps are omitted and replaced with either a flush fitted gasket or silicone application.
Trame Verticale curtain wall works on the same basis as Trame Horizontale however the emphasis is placed on the vertical sections which have ‘aerofoil’ face caps instead of silicone/gasket. The horizontale sections have either silicone or a flush fitted gasket applied to them.

Structural Silicone Glazed (SSG) Curtain Wall
Dortechs Structural Silicone Glazed Curtain Wall systems are used to create almost perfectly flush-fitted glass facades. The appearance of structural glazing is achieved by using profiles that are only visible on the room side. From outside, only the glazing and slender shadow joints are visible.
The gap between each piece of glass is approximately 25mm in comparison to the 50 to 60mm site line prevalent with traditional, visible grid curtain wall systems.There are two main types of SSG system Dortech offers;
The first is based upon specialist double glazed units which are manufactured to include an SSG spacer bar which incorporates a ‘U’ channel. Structural silicone is used to bond each piece of glass to the spacerbar. Once the curtain wall grid has been erected on site, these specialist glass units are delivered to site and locked into the grid using metal toggles.
