Duplus Architectural Systems Ltd are closely monitoring the Coronavirus situation via the recommended sources and in line with the available Government and Public Health England guidelines.

Unless otherwise instructed, we intend to provide a normal service whilst protecting our staff and customers as much as possible.

As of today, we have asked all our technical sales team to limit face to face contact as and where possible and to use alternative communication methods in the form of email or telephone. We ask anyone wishing to visit Duplus or our showroom, to make alternative arrangements and liaise via the aformentioned communication methods.

We have implemented procedures that will enable staff to work remotely should that become necessary and have instigated additional measures to limit potential exposure to the virus and to continue operating come what may.

We will keep you updated of any further developments that could impact on the service we provide.

Thank you and please be safe.
