ShutterView SD vs. ShutterView SS – The Difference

ShutterView SD and ShutterView SS are aluminium louvre shutters that look beautiful in windows, doors, entertainment areas, and as room dividers. At first glance it is hard to tell them apart. But there are important design features that make these louvre shutters suitable for homes in different areas. Let’s unpack these two security shutter types and the benefits of each.


What makes ShutterView SD and ShutterView SS louvres similar?

ShutterView SS and ShutterView SD don’t look hugely different. They are both fully framed aluminium shutters with louvres. Both are Trellidor security shutters. And both are used to provide protection from crime and other problems such as monkeys looking for food.



Hand-tilted louvres

Both shutter designs feature hand tilted louvres. This means that there are no external rods or other visible operating mechanisms. Just clean-lined, beautiful louvres. Hand-tilting the louvres creates privacy and stops anyone passing by from seeing inside. Tilting the louvres also blocks out the sun or allows sunlight to stream inside while the shutters are closed and locked if you prefer this.



Strong locks

ShutterView SD and ShutterView SS are fitted with strong Trellidor locks. Each lock has a unique computer cut key for extra safety. The locks can be used from both sides of the shutter. They can be locked from inside the home when you’re staying in, or from the outside when you’ve been out of the home.



Security shutter configurations

Trellidor security shutters have unique side locks to reduce friction for the smooth opening and closing of the louvre shutters. Both types of shutter can be manufactured for doors and windows as:

  •       Bi folds that fold in sections or panels to open.
  •       Hinged panels, with hinges on the left or right long vertical side.
  •       Sliding panels that open horizontally along a track.
  •       French doors, which are a set of hinged doors.
  •       Fixed panels that fixed in place and do not open.

The shutter and door or window need to work in a similar way to avoid the one interfering with the other. So the recommended format will depend on the type of door or window already in the opening.



Made to last

Trellidor shutters are made to last. Both types of louvre shutter are treated to resist corrosion, scratching, chipping, wearing and discolouration from the sun’s UV-rays. The smooth polyester powder coated surface is easy to clean and well-maintained shutters will look beautiful for many years. The louvres themselves are S-shaped so that rainwater runs off them easily. This, together with the Trellidor anti-corrosion treatment, helps prevent corrosion over time.



What makes ShutterView SS and ShutterView SD louvres different?

There are some design differences between the two types of Trellidor security shutter. The result of these differences is that ShutterView SS costs less than ShutterView SD to make. The benefit for the end user is that they have a choice of price and strength in these louvre shutters.



The louvres

ShutterView SD has double wall (two layer) aluminium louvres while ShutterView SS has single wall (one layer) aluminium louvres. There is also a difference in the louvre size, with ShutterView SD louvres slightly wider than ShutterView SS louvres.

This means that the ShutterView SD louvres are wider, thicker, and stronger, making it the more secure barrier. The ShutterView SS is still a reliable protective barrier, but obviously not as robust as the ShutterView SD.


The locks

Both shutters are fitted with strong Trellidor locks. Both lock types are operated using one key with a unique key code, using one keyhole. The locks are anti-bump and anti-snap to counteract lock picking and an attempt to break the lock cylinder. And each lock cylinder is supplied with three keys.

The locks for the two shutter options differ in one notable area. The ShutterView SD has a 3-point locking system that locks internally in three places. The ShutterView SS has a 2-point locking system that locks internally in two places. The more internal locking points, the stronger the lock. This makes ShutterView SD locks the stronger of the two louvre shutters.


Internal reinforcing

Trellidor security shutters all have internal strengthening features that make them strong security barriers. ShutterView SD, however, has an additional feature that makes it a premium strength shutter. Each louvre is reinforced with an internal threaded steel rod. This makes it an extremely strong shutter for the protection of a home in an area where the risk of crime is high.



The best locations for each ShutterView louvre shutter design

There is a reason for the differences in strength between the two Trellidor security shutter designs. Each shutter is suited to a different type of home and the risk of crime happening in the neighbourhood.

  • ShutterView SD is stronger and designed for high crime locations. These include free standing homes in suburbs, isolated places like remote holiday homes, and homes that are closed up for any length of time.
  • ShutterView SS is strong but engineered to be less expensive for medium to high crime locations. This makes them ideal for homes in estates, gated suburbs with layers of security measures, apartments, and coastal homes that are permanently occupied.




In conclusion, it really comes down to personal choice as to which louvre shutter design you prefer. If cost is the biggest factor, then ShutterView SS is the one for you. If strength is more important, then ShutterView SD is the ideal shutter to choose. To find out more about these shutters before deciding, contact your nearest authorised Trellidor supplier.
