Burglar protection - aluminium and PVC windows Cortizo

Burglar protection

If we want to protect our home against intruders, there are a number of elements to consider when choosing a window that will help reinforce its security.

They have the shape of a mushroom. This particular shape helps prevent levering from the outside, stopping the window from being lifted.

This makes the action of intruders more difficult and, in most cases, they will end up abandoning their attempted break-in.

Multiple locking points - aluminium and PVC windows Cortizo

Multiple locking points

The more locking points a window has, the harder it is to force. Hinged windows allow locking points around the entire perimeter, while sliding windows only allow locking points on the sides because the upper and lower areas must remain free for the sash to move.

Keyed handles - aluminium and PVC windows Cortizo

Keyed handles

This type of handle locks the window hardware. As a result, it is practically impossible to open the window, even by levering it from the outside. They are also a good choice if there are children at home, helping prevent them from opening the window and falling.

Laminated glass - aluminium and PVC windows Cortizo

Laminated glass

Laminated glass prevents access to the interior of the home in the event of breakage, as the small pieces of glass remain attached to the interlayer. This type of glass also helps avoid accidental cuts if the pane fractures.

How can the window be prevented from opening from the inside?

There are other window security elements designed to prevent opening from the inside. These solutions are very useful, for example, to avoid domestic accidents caused by improper handling by children.

Removable handles - aluminium and PVC windows Cortizo

Removable handles

If there is no handle, there is no opening. Removable handles and cremone bolts clip directly onto the escutcheon, making them very easy to fit and remove depending on whether or not the opening needs to be limited.

Logical operation hardware - aluminium and PVC windows Cortizo

Logical operation hardware

This solution for tilt-and-turn windows allows the casement opening to be blocked, preventing the full opening of the gap. This way, only the tilt opening remains operative for ventilating the home, for example. If access to the outside face of the window is needed for cleaning or maintenance, it can be done easily by unlocking the casement opening with a special key.

A secure window combines suitable hardware, locking points, high-performance glass and blocking solutions adapted to the use of each home.

Aluminium and PVC windows: useful guidance for choosing well

Choosing aluminium and PVC windows is not only a matter of price. In every home, orientation, climate, outside noise, opening size, façade design and daily use all influence the final decision. Cortizo Windows brings together solutions designed to improve thermal insulation, acoustic insulation, security, natural light and energy efficiency while preserving the character of each project.

Aluminium stands out for its strength, durability, dimensional stability and design possibilities, especially when large openings, slim profiles or highly customised finishes are required. PVC offers excellent insulating performance, low maintenance and a strong balance between comfort and value for home renovation. In both cases, the right choice should take into account the glazing, opening type, installation quality, orientation and the real needs of the household.

Beyond comparing materials, it is useful to define what needs to be improved: reducing energy loss, gaining more silence, increasing security, simplifying maintenance, renewing the appearance of the home or preparing it for more efficient consumption. The Cortizo Windows retail network helps assess each project, identify the most suitable solution and request a professional quotation for replacing windows with a close, project-focused service, without spam or unrelated calls.
