Introduction to Sisaltech

John Ferguson, Founder & CEO

The construction industry produces a shocking amount of waste. Construction, demolition and excavation accounted for 62% of the UK’s total waste in 2018 and this must change urgently.

Sisaltech creates innovative construction insulation that is easy to switch to, sustainable by nature and completely recyclable.
