Is it time to invest in Roller Shutters? With summer heat or autumn storms it is always the perfect time to consider installing Roller Shutter Blinds for your home or business. Windows are often an area of the home that is forgotten when it comes to building or renovating. Many home owners have found adding outdoor roller shutters to windows can not only save you on heating and cooling cost (who doesn’t need that right now?) they can also add a very important layer of security . In this article we explore the many features and benefits of roller shutters and the main factors that influence people’s decision when investing in shutters. Roller Shutters are popular with Australian homeowners because of their many long-term benefits such as being easy care, increased security, improved insulation, light control and durability. Benefits of adding Roller Shutters to your home. Added security to windows that may be vulnerable to break ins or vandals Privacy on demand, with the push of a button. Protection against bad weather extremes, storms & bushfire (BAL 40) Increase Energy Efficiency from Insulation and Thermal Control Sound deadening even in heavy traffic locations or from noisy neighbours Peace of Mind for your home even when you can't be home How do roller shutters work? Made from horizontal slats or panels the high-quality Rollasheild roller shutters are made from durable materials such as aluminium or steel that are mounted on the exterior of windows and sliding doors. They can be a manual or motorised operation making them easy to operate for all users. Not all roller shutters are equal . Like most things when it comes to quality, you get what you pay for. Cheap roller blinds take short cuts with materials and usually don’t have the same insulation properties. At SSTG we supply and install Australian made, Premium Roller Shutters for quality security and peace of mind. The Rollashield Curved Series slat is a double walled cavity with PU foam injected during the roll forming process. This process provides economical strength and insulation qualities while maintaining exceptional working performance of the slat. The curved shape of the slat provides optimal lateral strength and minimal roll sizes, offering a much smaller head box size. Main factors that influence people’s decision on roller shutters are : •Security •Energy Efficiency •Design - Colour/Aesthetics •Functionality •Quality Manufacturing •Maintenance and Repair •Value for Money How do roller shutters enhance security? Roller shutters act as a physical barrier against intruders or vandals which in turn becomes a visual deterrent to would be thieves looking for an easy entrance or exit point. Made from durable materials and equipped with robust locking systems when fully closed over a window or sliding door, they provide an added layer of barrier protection for your home. Quality and reliability play a big part in the cost of a roller blind. Obviously there is always a “cheaper version from overseas” but is that necessarily financially viable in the long term? We've put together our top 10 benefits that influence peoples choice when considering the purchase of roller shutters. 1. Protection against Bushfires Protection from Australia’s harsh climate. Bushfires are a common problem in Australia. Roller shutters can help to protect your home from bushfires and other fires. A bushfire-rated roller shutter can act as a barrier and protect your home against heat and ash. Your windows can also be saved as fires can shatter the glass. For quick operation, electric roller shutters are also a consideration for bushfire-prone homes. 2. Home security Improve your home security system. Another reason to choose roller shutters is that they provide an extra layer of security for your home. Roller shutters have a locking system and act as a barrier to intruders and deter break-ins. Thieves look for homes with easy access, and when they see shutters, they're put off. This means that roller shutters, in a similar way to security doors, also act as a visual deterrent for home intrusion. 3. Energy Efficiency. Increase your homes energy rating with insulation and thermal control. Roller Shutters are highly resilient and will be able to withstand all types of weather conditions without warping. Enjoy temperature control with quality roller shutters made with insulated slats. This means they are effective in stopping heat from escaping your home in winter and can reduce heat from entering your home in summer. This enables you to keep your home at a comfortable temperature all year round while you save money on energy bills. Roller shutters offer insulation by creating a barrier between the window and the interior. This helps to minimise heat transfer, keeping your home cooler in summer and warmer in winter. 4. Weather events Protection from the elements. Roller shutters add protection against all types of weather conditions from hot sunny days to stormy weather, wind, rain and hailstones. Quality roller shutters that are professionally installed will not rattle during high wind and can help to protect your home from trees and storm debris. 5. Ease of use. Privacy On Demand with a Single button Manual verses automatic. In high up and hard to reach places an automatic system that only requires the push of a button far out way the additional cost. 6. Noise Reduction Sound deadening from traffic and neighbours. Roller shutters don't only offer light control but sound control too. Quality roller shutters can reduce noise from traffic, neighbours, animals, aeroplanes and more. 7. Light control From daylight to block out with the flick of a switch. With roller shutters, you can control how much light enters a room. If you need complete darkness you can close the shutters completely. This is a great option for people who work at night and sleep during the day, have young families that nap during the day. 8. Stylish design Roller shutters are available in a variety of colours to suit the design of your home and your personal style preference. Today's quality roller shutters are streamlined and fit neatly into a secure headbox pelmet above a window or door, keeping your view completely unobstructed in the up position. And because roller shutters are installed on the outside of your home, they don't take up space on the inside of a room. 9. Add value to your home As a permanent window fixture, quality roller shutters add value to your home. Because roller shutters have many benefits if you decide to sell 10. Easy to maintain. One of the many reasons homeowners choose roller shutters is because of the easy cleaning process - it's easy to keep roller shutters looking brand new for years with very little effort. Before you begin cleaning, ensure your roller shutters are completely rolled down. To clean the outside of your roller shutters, simply hose with a down motion and side-to-side with low water pressure. For embedded dirt, you can wipe with clean water, mild detergent and a damp cloth. Depending on the grime build-up, you can use non-abrasive cleaners, a soft cloth and warm water. When you need to get in between the individual slats, a soft-bristled brush and soapy water can help remove grime build-up. Dish soap can also be used but avoid steel wool or abrasive cleaning solvents as these can damage the surface of your roller shutters. Also, avoid a high-pressure hose as this can damage the slats.
