Vacuum Insulated Glass SPACIA

A thermos bottle used at home also has a dual layer structure.
Such structure is applied to windowpane.
A 0.2 mm thick spacer is placed between two sheets of glasses and their circumference are made airtight and vacuumed.

Its structure is like this:

1. Heat Insulation Performance
2. Minimizing Dew Condensation
3. Acoustical Insulation, and Sound Shut-out Performance
4. Strength Against Wind Pressure

This Type of Glass in Superior than any other Glasses with regard to each one of those above four(4) features.

Unit = Kcal/mh degrees Centigrade. Calculation Method per JIS R3106 and JIS R3209
These figures probably not attract you much, but it is said that some 50 per cent of heat in a house leaks out through windows.

The Vacuum Insulation Glass in combination of the Low-E glass has an equivalent performance that of a Heat Insulation Wall Material has.

Minimizing Dew Condensation

A room temperature of 20 degrees Centigrade with a humidity of 60% is quite comfortable to us in the winter time, but dew condensation on the windowpane is a problem with us.

This Vacuum Insulation Glass solves such problem.

Sound Insulation Characteristics and Sound Insulation Performance

Fulfills the Class 30 of JIS Sound Insulation Requirements.
Features an equivalent function of Sound Insulation and Sound Isolation type Insulation Glass.

Strength Against Wind Pressure

Vacuum Lamination Glass is made of sheets of glass with a spacer, and is rigidly adhered to each other by means of the atmospheric pressure. It is proved to have an equivalent rigidity of a single sheet glass of the same thickness.

Thus, thinner but large sized glass can be used in these days.

As of October 1997, maximum size of glass sheet available is 2,400 x 1,350 mm.
