Are the evacuated tubes made of Pyrex?

Pyrex is a brand name, it is renowned as having ‘tough glass qualities.’

Our tubes are not ‘Pyrex’ brand, however they are composed with the same materials giving them extreme strength and toughness.

Tubes are 25mm hail rated and we have tested them against rocks, cricket balls branches to name a few.

They are very tough but if you hit them a few times with a hammer they will break. In the last 3 years I have only had six tubes ordered for replacement, one was construction damage (they dropped a cement building block on it) and the other one was a tube being dropped from a roof in the installation process along with some as spares in cyclone prone areas.
