Claims14
A fire-protection glass product having a heat shielding characteristic, comprising:
- a fireproof glass plate;
- a heat ray reflection film formed on at least one of opposite surfaces of the fireproof glass plate;
- and
- an oxidation prevention film formed on the heat ray reflection film.
A fire-protection glass product having a heat shielding characteristic, wherein:
- a heat gain is 1.0 W/cm2 or less and an average transmittance for visible rays having a wavelength between 400 nm and 700 nm is 60% or more after one surface of the glass product is heated for 30 minutes in accordance with the ISO834 standard heat curve.
A fire-protection glass product having a heat shielding characteristic, wherein:
- after the glass product is heated for 30 minutes at 800° C., an average reflectance for infrared rays having a wavelength between 1500 nm and 2500 nm is 10% or less and an average transmittance for visible rays having a wavelength between 400 nm and 700 nm is 60% or more.
A method of using a fire-protection glass product having a heat shielding characteristic and comprising a fireproof glass plate with at least a heat ray reflection film and an oxidation prevention film formed on one surface thereof as a film-deposited surface;
- wherein:
- the glass product is used so that the film-deposited surface is placed outside of a protection area.
