The Sunbury that used to exist as a quiet little fringe town on the outskirts of Melbourne’s north west has been swallowed up by something a whole lot more dense. Corridor expansion has brought new estates and a whole lot more people to the area. The type of housing is getting a lot denser too. That is bringing with it the kinds of vulnerabilities that occur when new housing development happens way faster than people get to know the place. The upshot of all this is that the questions Sunbury residents are asking builders, hardware stores, and door suppliers are a whole lot more to the point than they used to be. It is no longer, “Do I need a security door?” It is, “Which one actually works?”
The Market Is Full of Products That Look the Part
The difference between a real security doors Sunbury product and one that just looks like a security door is a big deal in growth corridor markets like Sunbury. So many houses are being built so fast, and every decision about what features to include is under a lot of cost pressure. A flyscreen with a heavier frame is a lot more than just a security screen. It is still just a flyscreen with a heavier frame. A hollow core door with a deadbolt on it because the builder said so is not a secure entry point either. The rules governing real security doors in Sunbury are covered by the Australian Standard AS 5039. What it actually tests for is more specific than most people probably think. It assesses how well a door resists being pulled, pushed, or jimmied open. It also tests what happens when you try to cut or hit the mesh or grille. The standard also measures how well the locking system can withstand being fiddled with. If a product carries the AS 5039 stamp of approval, it has actually been independently tested against those things. A product that describes itself as a “security door” in its sales pitch has not necessarily been tested at all.
Steel, Aluminium, and Timber-Backed: What Each Does
Steel security doors have the very best impact resistance ratings. Unfortunately, they are also the worst when it comes to thermal transfer. In Sunbury’s climate, which is hotter than Billy’s hat in summer and colder than ice in winter than the inner suburbs, a steel door soaking up afternoon sun can get scorching to the touch. It also contributes to the entry area getting hot. A powder coat helps reduce that a bit. It does not solve the problem. Aluminium security doors, on the other hand, are a lot lighter, easier to use, and do a much better job on the thermal performance front. The catch is that they have lower impact resistance than steel. Most people living in residential Sunbury do not need anything super hardcore. If you live in a high-risk area or you run a business, you are going to want to go for steel. Timber-backed composite options fall somewhere in between the two on most of the important performance criteria. They are probably a good choice if you own a period home where steel or aluminium would wreck the look.
The Installation Detail Most Homeowners Miss
If you have got a security door rated to AS 5039 specifications but it has been fitted into a poor-quality frame, you get the performance of the frame, not the door. Many homeowners only discover this after the fact. The door that should have been far more secure fails because the installation was not done properly.
What to Expect on Price and Timeline?
Security door prices in Sunbury vary depending on whether you are buying a supply-only package or a supply-and-install package. For a run-of-the-mill single-entry door that meets the AS 5039 standard, you are looking at anywhere from $800 to $1,800 when installation is included. The final price depends on the material, profile, and mesh specification you choose. Sliding or stacker security screen installations are going to cost you a bit more.
