The Expel Ultra 55mm 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.
The roller shutter has been manufactured from 55mm insulated 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 a more cost effective alternative please see our Expel Ultra 41mm model.
