Our Expel Ultra 41mm 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 41mm insulated lath providing low-medium security on openings 3000mm wide and smaller. The insulated lath allows better retention 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 higher security or larger openings please see our Expel Ultra 55mm.
