Founder Story

About Jan Szliszka

Hi, I'm Jan Szliszka, founder of Environ Industries.

I've spent more than 30 years working in the insulation and sheet metal industry, starting my career in the UK before moving to Australia. Over that time, I've worked across food manufacturing, pharmaceuticals, commercial facilities, hospitals, refrigeration plants, steam systems, and heavy industry.

Environ Industries was built on a simple belief: clients deserve experienced tradesmen, quality workmanship, and practical solutions that genuinely reduce energy loss and improve plant efficiency.

Every project we take on is approached the same way — assess the site properly, recommend what will actually deliver value, and then deliver it to a standard I'm proud to put our name on.

"Clients deserve experienced tradesmen, quality workmanship, and practical solutions that genuinely reduce energy loss and improve plant efficiency."
