StoVentec Glass can be used as an external rainscreen cladding system, and as an internal cladding or decorative option.
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.
The system comprises a glass faced composite panel, thermal insulation and sub-construction. Tempered glass is adhered to a carrier board to produce an inseparable composite panel, which protects the substrate from rain. A circulating air layer is formed between the hung panel and the mineral wool insulation, mounted directly onto the substrate. Insulation on the outside of the construction keeps the wall warm and reduces the risk of condensation and minimizes temperature fluctuations.
Rigorous testing under extreme conditions has resulted in BBA accreditation, conformity with relevant NHBC standards, reaction to fire classification in line with current national Building Regulations requirements, and a minimum expected life of 30 years.
The StoVentec Glass A rainscreen system is manufactured bespoke to your requirements for size, shape, colour and finish, offering great aesthetic potential for facade designs, with a reaction to fire classification of A2-s1, d0. StoVentec Glass is suitable for specification within high traffic areas. The system has passed all industry standard soft-body and hard-body impact tests to CWCT standards.
The system has also passed stringent bomb blast tests, demonstrating its suitability for use in public safety zones. Complies with ASIAD 2017 (Aviation Security in Airport Development), SIDOS 2018 (Security in the Design of Stations) and CPNI (Centre for the Protection of National Infrastructure).
