COVID 19 – Message from Timofei Yeremeyev, Managing Director

Trading Update 28th April 2020

At Permavent we been continuing to operate a limited distribution service to support the requirement for any special projects. As businesses get to grips with how to implement safe working practices, we have seen a number of our customers re- opening on a limited basis and Permavent will be scaling up its distribution in order to support our customers. Our manufacturing has been operating at a reduced level, but we are constantly monitoring demand and production will be ramped up in line with this.

On a lighter note the sales team have been keeping themselves entertained with what has now become our weekly Friday night quiz. Can you guess which member of our team is the quiz champ?

Please contact us if you have any questions about trading with Permavent at this challenging time.

We hope that all our customers and their families are keeping safe and well.

Timo.
