INSULATING GLASS
Float glass naturally exhibits low resistance in either heat gain or heat loss since it is highly conductive to heat exchange and has very low insulating properties. VASGLASS produces insulated architectural glazing units of dimensions up to 6.000mmX3.210mm, comprising of glass panes separated by either dehydrated air or a gas filled cavity, using spacers filled with silica desiccant protecting against moisture build-up . Depending on the choice of glass types and their subsequent arrangement, the insulating properties of the glazing unit can be combined with properties such as solar control, soundproofing, and safety.
As a rule, the constituent panes of an insulating glazing unit are numbered starting with the outer glass surface, moving inwards.
Main characteristics: 1st level adhesion (Butyl)
Adhesive agent initially in solid form that is heat-softened, applied to the face of the spacer on each side, followed by the panes being pressed against the spacer. It demonstrates optimal adhesion and durability. 2st level sealing
There are three distinct categories of sealants suitable for this stage, based on their chemical composition. Polysulphide (cold application), hot melt, and structural silicone.
- HOT-MELT
Known as hot sealant, it is applied through a nozzle that heats up the material which then solidifies as it gets colder. It is the most commonly applied material due to its ease of use and rapid solidification, however demonstrating less than optimal behavior in relatively high and relatively low temperatures, making it less suitable for marginally hot and cold climate conditions.
- SULFATE BASED
It is a two component sealant, exhibiting excellent performance against weathering, suitable for all types of architectural insulating glass. It is applied via specialized equipment that mixes both components simultaneously and accurately during application, resulting in increased durability over time.
- STRUCTURAL SILICONE
One or two component structural sealant, exhibiting excellent performance over time, suitable for both interior and exterior, structural or semi-structural special glazing applications.
