Are security screens worth it? A Townsville view

In a town where we live with the doors open half the year, here's what security screens actually give you, and what to weigh up.

The short answer

For most Townsville homes, yes. Good security screens let you leave doors and windows open for the breeze, keep the insects out and give you peace of mind when you're out or asleep. The trade-offs are the upfront cost and some cleaning, especially near the coast. If the budget is tight, start with the doors you open most.

For a lot of Townsville families, the best thing about security screens has nothing to do with security. It's being able to leave the back door open on a hot afternoon. That's a good place to start.

What you get

The breeze, day and night. Townsville nights can stay warm for months. Screens let you sleep with the windows open and leave the sliding door open while you're inside, without leaving the house wide open.

No mozzies. A fine stainless steel mesh like Invisi-Gard keeps insects out, so it doubles as a flyscreen.

Peace of mind. Lock up and head out for the day, or go to bed, knowing the doors and windows are properly closed off. Invisi-Gard doors and window screens are tested to Australian Standards against knives, pry bars and impact.

A better-looking front of house. A smart security door makes the entry look finished, especially with the frame colour matched to your windows.

What to weigh up

The cost. Good screens aren't cheap, and the stainless steel options cost the most. Here's what affects the price.

Cleaning. Close to the water, screens need a regular wash to keep looking good and to keep the warranty. It's a quick job. Here's how to clean security screens.

The look from inside. Woven mesh is very fine and easy to see through. Perforated aluminium and diamond grilles are more visible. It's worth seeing them in person before you choose.

Making it work on a budget

  • Start with the doors you open most. For most families that's the back door and the sliding door to the patio.
  • Then the windows you open at night. Usually the bedrooms.
  • Mix and match. Invisi-Gard where you want the clearest view, and Alu-Gard or diamond grille where budget matters more.

The bottom line

If you live with the doors open, good security screens are one of the most useful things you can add to a Townsville home. Book a free measure and we'll show you the options for your place.

Common questions

Do security screens let the breeze through?

Yes. Woven stainless steel mesh like Invisi-Gard is fine enough to see through and lets air move freely, so you can keep doors and windows open.

Are security screens tested?

Invisi-Gard security doors and window screens are tested to Australian Standards against knives, pry bars and impact. Ask what any product you're considering has been tested for.

Do I need security screens on every window?

No. Most people start with the doors they use most and the windows they like to leave open at night, then add more later.
