The Expel Ultra roller shutter combines a fly screen with an insulated roller shutter allowing you to have greater control of your environment and adding security to your premises.
The fly/insect screen is made from glassfibre and PVC weaved to allow 66% visibility to ensure that insects are kept out whilst airflow and sunlight are kept to a maximum.
These models are manufactured from either 41mm or 55mm insulated aluminium lath providing medium-high security. The insulated lath allows better retention of heat in the winter as well as offering sound reduction qualities and a near blackout of sunlight making this the ideal product over bedroom windows to help you sleep at night. 
For larger openings, the 55mm model may have to be used as the 41mm model is designed for smaller dimensions.
  • Over windows, patio doors, balcony’s in domestic houses
  • Food preparation areas/restaurants
  • Areas where there are lots of flies, mosquitos or other insects
  • Allows high visibility 
  • Allows a high level of airflow
  • Offers medium-high security
