Explosion-proof windows - explosion-resistant windows for objects

Fixed Blast-Resistant Windows designed for objects where translucent blast protection is required without opening flaps. The section presents the parameters of explosion-resistant windows, classes according to GOST R 57471-2017 and information on tests confirming protection from shock waves.

The barriers of the industrial explosion series are intended mainly for oil and gas, petrochemical, chemical complex facilities, enterprises producing pyrotechnics and ammunition, large railway junctions. When assessing suppliers, require Test confirmation video!In order for the window to correspond to the class of VZ 50 GOST and P 57471, it must be tested by detonating at least 500 kg of TNT at a distance of not more than 30 meters. And with class VZ 28 - at least 500 kg of TNT at a distance of no more than 46 meters. The window after the explosion should not be broken. The test sample shall be larger than the product supplied or larger than 2600×2600.

The market is full of counterfeits!

The only known obstacles tested by TNT equivalent similar to a real accident explosion, and certified according to GOST R 57471-2017 izm.1 The product during the explosion does not deform, the glass does not crack, which allows you to withstand the fire after the explosion.Fire resistance (GOST 53308-2009) E60, EIW60, E90/IW60depending on the composition of the glass and filling profile.

Bullet-resistant - BR-1 and burglar-resistant (glass) - R6 Performance in accordance with GOST 30826-2014 Improved performance properties: Frame with thermal fracturing prevents freezing and condensation. It is possible to achieve CST - 0.8 m2·C / W. As a decorative case, a staff aluminum profile is used, which does not rust aesthetically looks. Simple installation of glass.Cheap windows of class VZ 5 (A) in the section Explosion-resistant barriers
