Double insulated glass(DGU)
Double glass units consist of two panes of glass separated by a spacer around the edges and sealed to
the perimeter in factory controlled conditions. The spacer contains a desiccant (drying agent) which
eliminates moisture vapour in the cavity.
Double glass units are available in many combinations
including clear float, tinted float, reflective float, laminated, toughened, obscure and with Low-E
1. Energy saving, noise-insulation, warm keeping,
2. Charging in special gases, such as argon gas may
further improve heat and sound insulation.

P.V.B Laminated Glass
Laminated glass is a combination of two or more glass sheets with one or more interlayers of plastic (PVB) or resin.
In case of breakage, the interlayer holds the fragments together and continues to provide resistance to the passage
of persons or objects. This glass is particularly suitable where it is important to ensure the resistance of the whole
sheet after breakage, such as, shop-fronts, balconies, stair-railings, roof glazing.
are two types of laminated glass:
(a) PVB and (b) resin laminated glass.
PVB laminated glass is two or more sheets of
glass which are bonded together with one or more layers of PVB under heat and pressure to form a single piece.
Resins laminated glass is manufactured by pouring liquid resin into the cavity between two sheets of glass
which are held together until the resin cures.
1. Good safety performance, anti-bumping and
2. Good soundproof and heat isolation effect.
3. Strong UV resistance.
4. Diversified colors.
5. Durable and fadeless.
