Types of Lamination
Cast In Place Lamination
This type of lamination is achieved by combining three different types of chemicals, that once mixed together can then be pumped between the edge taped layers of glass & then laid flat to cure once all the excess air has been removed. The curing is caused by a chemical reaction when all components are mixed. The interlayer thicknesses that can be achieved by HSG using this type of lamination are 1mm, 1.5mm, 2mm & 3mm
The benefits of CIP lamination are that multi-layer laminated glass products can be achieved with ease & the size of the laminated product is only governed by the sizes that glass processors can supply. It is a great product for external applications & used by us for the manufacture of our flooring panels. It's has a fantastic optical quality but on close inspection a 4-6mm witness line can be seen around the perimeter of the panel but is extremly faint.
EVA Lamination (Ethyl Vinyl Acetate)
EVA lamination is achieved by adding sheets of material between the layers of glass, the more sheets you add the thicker the interlayer will become. The glass is then put into silicone bags & put under constent vacuum for the entire curing process. The glass is then heated to tree different temperatures over several hours for the cross linking to take place & laminate to cure.
EVA laminated products are great for balustrading/balcony panels and offer better moisture resistance than most PVB interlayers. Different types of materials such as meshes, fabrics, polycarbonates, certain papers, PET films & organics can be added to give special effects & in some cases extra security.
The maximum EVA size we can produce here at HSG at the moment is 3000 x 1350mm or 2850 x1500 mm
