Bi-fold and French door insect screens by National Screens

At last an insect screen designed for bi-fold doors that's attractive and safe to operate. The Monarch Range of insect screens is rapidly gaining recognition as the designer's choice of insect screen for bi-fold door and stacker doors.

Specifically designed to screen large openings, our patented design uses pleated insect mesh that incorporates a disappearing track and an anti blow-out retaining clip. There are no channels at the sill to trip over and no troublesome breaking systems. The screen has a building in tolerance of +/- 15mm, suitable for openings 2.4m high x 4.0m wide. Visit
