StoVentec Glass, ventilated rainscreen cladding system - Glass Faced Rainscreen Cladding System

StoVentec Glass panels can be supplied in virtually any shape, including curves and arcs. Furthermore, the panels can be cut to allow incorporation of lighting or control panels. The invisible sub-construction results in an open-jointed grid, with no visible frames, rails or fixings. Part of our manufacturing process includes the fusing of colours on to the back of the glass, before the toughening process. The colour is baked into the rear face providing permanent coloured glass panels that will not wear, scratch, fade or incur water damage. Sto can also match to almost any colour.

Screen printing offers additional design possibilities - patterns, illustrations, photographs or corporate logos - these are applied to the rear side of the glass panels, expanding the scope for individuality. Choose single-colour, multi-colour or metallics for your bespoke design, with a gloss, reflective or matt finish. Textured glass is also available, adding a three-dimensional element to the surface. With StoVentec Glass, the joints are open, making them an important element of the overall design. This allows the creation of regular or irregular grids and coordination with window and door openings.

The sub-construction is designed bespoke to your project, and is a combination of stainless steel wall brackets, aluminium T-profiles and horizontal rails. Stainless steel brackets have an extremely low thermal conductivity and do not require thermal breaks to avoid cold bridges. They far outperform aluminium brackets, even when a thermostop is included, so less insulation can be used to achieve the same u-value. The inherent high strength of StoVentro brackets means that fewer brackets are usually required and the stainless steel grade is also suitable for use in marine environments.

In addition, Sto can offer an independently approved and tested sub-construction to Passivhaus standards, as well as tailored advice on the sub-construction design, joint detailing and penetrations.

In exterior applications, the substrate typically has the insulation applied on the air barrier. This keeps the inner leaf at a similar temperature to the internal air and minimises the risk of condensation forming or temperature fluctuations. The outer glass panel, which also prevents the majority of rain wetting the insulation surface, forms a ventilated cavity to its rear face, ensuring any moisture from the interior is quickly dispersed.
