Multifloat is a laminated glass consisting of two or more glass plates between which sheets of polymeric material with plastic behaviour are interposed.
The most commonly supplied interlayers are: PVB, polyurethane, DG41, SGP.
Laminated glass combines strength and safety features with its traditional qualities of transparency, unalterability and durability.
Hard Glass produces MULTIFLOAT in a range of different versions: the total thickness and composition of the laminate may be selected to achieve the necessary safety levels and performances.
Laminated safety glass consists in two or more sheets of glass joined together by one or more sheets of polyvinyl butyral (PVB) and it is obtained by heating and pressure process.
PVB achieves, at the end of the manufacturing process, high and stable characteristics over time in terms of transparency and adhesion to glass sheets.
The PVB interlayers have an excellent ability to absorb the energy of an impact and to disperse it quickly, maintaining the shape even after the break, and avoiding any injuries due to the glass fragments. In case of glass breakage, the fragments remain adherent to the interlayer.
SentryGlas® is a ionoplast interlayer that helps creating safer, lighter and more performing laminated glass.
SentryGlas® is extremely stiff and strong, and ensures a high adhesion of the glass sheets to each other, making the laminated glass more resistant to loads and impacts than traditional laminated glass.
Therefore, laminated glass with SentryGlas® shows low mechanical strain under loads, and almost the same behaviour as monolithic glass of the same thickness .
Glass laminated with SentryGlas® can withstand much higher impacts than common laminated glass with PVB interlayers, and has got an excellent outstanding post-breakage resistance to creep and collapse.
The interlayer becomes a more performing structural layer in the multilayer composite, offering architects and engineers greater design freedom
DG41® structural pvb interlayer is a tough, resilient film used in all glass applications that require high structural performance.
DG41® guarantees excellent adhesion between the glass sheets with maximum resistance to high and low temperatures, even after impacts and under stress.
Thanks to the rigidity of DG41® laminated glass and to its superior adhesion to glass, the thickness of the plates can be significantly reduced to support uniformed distributed loads.
