Use more than one layer. External awnings stop sun before it reaches the glass, while shutters and blinds control light and heat inside. An external shade cut annual cooling demand by 71.8% on a north-facing Sydney window in a simulation (Sorooshnia et al., 2023).
Roller shutters are external window coverings installed over windows or doors. They roll up and down to create a protective barrier between the glass and the outside environment.
They are commonly used to improve home security, reduce heat, block harsh sunlight, increase privacy, reduce outside noise, and help protect windows from changing weather conditions.
Unlike interior blinds or curtains, roller shutters sit outside the home, which means they help stop heat, light, and exposure before they reach the glass.
Most people do not choose roller shutters for decoration alone. They choose them because they solve practical problems.
They are especially useful for Sydney homes that deal with strong afternoon sun, street-facing windows, noisy surroundings, exposed weather conditions, privacy concerns, or rooms that need stronger light control.
In an Australian Institute of Criminology study of active burglars, minimal security meant no dog and no working alarm, security screens or roller shutters, while effective security meant switched-on alarms, security screens, roller shutters and dogs. 75% of burglars took under five minutes to get in, and offenders knew that fake alarms and fake cameras did not deter (AIC, 2014). Only 30.9% of Australian households had a security screen or shutter on at least one window in 2017-18 (NSW: 26.1%), and households that had a break-in were 2.7 times as likely as others to install or upgrade security within 12 months (Australian Bureau of Statistics). In 2024-25, 196,600 Australian households (1.8%) had a break-in, and 44.2% of break-ins involved property damage (ABS, 2024-25).
Roller shutters work best as part of layers. Pair them with security screens and doors and a working alarm, and add plantation shutters or blinds inside for privacy and light control.
Embers, not flames, destroy most homes. In Duffy, the worst-hit suburb of the 2003 Canberra fires, 85% of house attacks involved embers, yet 47% of surveyed houses were destroyed, and only 3% of the 229 surveyed houses had roller shutters (Bushfire CRC and CSIRO). Plain window glass breaks at about 12 kW/m2 of radiant heat, while toughened glass breaks at about 40 kW/m2 (CSIRO, Royal Commission). In a 2025 Queensland University of Technology test under a BAL-40 heat curve, a 1.2 mm steel shutter sheet held window glass to a 52 to 74 C rise, while a glass-fibre blanket alone let glass reach 211 C (QUT, 2025). Shutters are effective radiation barriers only if they shield the whole window and do not combust (CSIRO), and under AS 3959 they must leave no gap over 2 mm when closed. Tell your consultant your property’s BAL rating so they can confirm the right product.
External shutters block the sun before it reaches the glass. In a simulation study, thermal energy demand fell by 23% with light blinds and by up to 35% with massive external shutters (San Martin et al., Building Simulation, 2017). Honest context: the US Department of Energy’s window attachment benchmark did not model roller shutters because of a lack of reliable simulation models (DOE and LBNL, 2013), and Sustainability Victoria notes shutters help with insulation only if they fit tightly with no gaps (Sustainability Victoria). Apollo’s made-to-measure Enduragard shutters are cut to your opening for a tight fit. For outdoor areas, see awnings and Ziptrak outdoor blinds.
Roller shutters give a modest, useful reduction in noise. In laboratory tests, extending a roller shutter raised a window’s sound insulation by 3 to 4 dB, for example from 32 to 36 dB (Universidad Politecnica de Madrid, 2019). The World Health Organization estimates indoor-outdoor noise differences of about 10 dB for open windows, 15 dB for tilted windows and 25 dB for closed windows, so closing the window is the first step (WHO Europe, 2018). Combine closed windows with shutters in bedrooms facing busy roads.
Hail-prone days rose by about 40% around Sydney and Perth between 1979 and 2021, and the seven costliest hailstorms of 2014 to 2021 caused AUD 7.4 billion in insured losses (UNSW and Bureau of Meteorology, 2023). Wind-rated roller shutters are not rated to withstand heavy debris, but they do protect glass from lighter debris and may reduce the wind and water entering your home if a window breaks, according to the National Emergency Management Agency. Ask your consultant which rating suits your suburb.

They make break-ins harder, and burglars named roller shutters and security screens as part of effective security. 75% of surveyed burglars were inside within five minutes, so a barrier and a working alarm together matter (AIC, 2014).
Properly specified shutters can protect glass from radiant heat and embers, but only if they cover the whole window and leave no gap over 2 mm when closed. Tell your consultant your BAL rating (Bushfire CRC and CSIRO).
Wind-rated roller shutters protect glass from lighter debris, but they are not rated to withstand heavy debris (National Emergency Management Agency). Hail-prone days rose about 40% around Sydney and Perth between 1979 and 2021 (UNSW and BoM, 2023).
By about 3 to 4 dB in laboratory tests on a window (Universidad Politecnica de Madrid, 2019). Closing a tilted window gains about 10 dB (WHO Europe), so use both.
