Window locks – find manufacturers and suppliers

Window locks are mechanical or electronic devices that protect windows from unauthorized access.

They are used to prevent break-ins and increase security in private and commercial buildings. There are various solutions depending on the type of window and the desired level of security.

Below you will find how they work and an overview of the use of window locks and their advantages:

How window locks work:

Most window locks are based on three basic principles:

Mechanical locks:

1. Mechanical security devices prevent the window from being forced open or pried open. They reinforce either the locking mechanism or the frame.
2. Window handles with a lock: These replace the standard window handle and can only be unlocked with a key or a push mechanism.
3. Additional locks: Are mounted directly on the window frame and block the opening of the window.
4. Mushroom head locks: Special pins in the mechanics of the window that make it more difficult to pry open.
5. Bar locks: A vertical lock that locks the window over its entire height.
6. Hinge side locks: Reinforce the hinge side of the window to prevent it from being levered out.

Electronic locks:

1. In addition to mechanical security, electronic systems offer active monitoring by sensors.
2. Magnetic contacts: These report if a window is opened without authorization.
3. Glass breakage sensors: Detect vibrations or breakage of the window pane and trigger an alarm.
4. Smart home integration: Sensors can be integrated into alarm systems or home automation systems to send notifications to smartphones or security systems.

Security glazing:

1. Specially reinforced windows offer additional protection.
2. Single-pane safety glass (ESG): More resistant to impact, but shatters into small, less dangerous pieces if broken.
3. Laminated safety glass (LSG): Two or more layers of glass with a plastic film in between, which holds the glass together in the event of breakage and makes penetration more difficult.

Use and installation of window locks:

Depending on the building and location of the window, different types of security are recommended:

1. First floor & easily accessible windows:
These windows are particularly at risk, so reinforced mechanical security or alarm systems should be used here.

2. Roof windows & hard-to-reach windows:
Are usually less at risk, but a lockable handle can still be useful.

3. Rented apartments:
Mobile or removable solutions such as lockable handles or window bars are suitable.

Advantages of window locks:

• Increased burglary protection.
• Mechanical locks are often low-maintenance.
• Electronic security systems can be combined with smart home systems.
• Easy to retrofit to existing windows.

Window locks offer effective protection against break-ins and can be customized to meet individual security requirements. Mechanical locks prevent the window from being forced open, while electronic systems sound the alarm at an early stage. A combination of both methods ensures maximum protection.

Here are the most important aspects to look out for when buying window locks:

• Before making a purchase, an inventory or precise planning is necessary in order to select the optimum window locks:
• Is the building a detached house, apartment building, commercial property, or a public building?
• What is the position of the windows? First floor windows are particularly at risk, as are higher windows, depending on access options.
• How high is the risk of burglary? In which regions or areas is the risk of burglary particularly high?
• Wooden, plastic, aluminum windows or listed windows require different security solutions.
• Are alarm systems, cameras or other security systems already installed?
• High-quality window security systems should be certified in accordance with recognized security standards:
• DIN 18104-1 & DIN 18104-2: Standards for retrofittable mechanical security systems.
• RC classes (Resistance Class) in accordance with DIN EN 1627: Resistance classes for burglar-resistant windows and doors.
• RC1: Basic protection against physical violence.
• RC2: Protection against opportunist burglars with simple tools.
• RC3-RC6: Higher protection for commercial and high-security areas.
• VdS certification: Particularly important for insurance requirements and tested security solutions.
• Mechanical or electronic security devices? The choice depends on the requirements:
• Protection against prying is very high with mechanical security devices. Electronic locks usually only generate an alarm when forced open.
• Mechanical locks are usually cheaper. Electronic locks have higher purchase costs.
• Mechanical locks are easy to retrofit. Electronic locks are also easy to retrofit but require a power source.
• Mechanical fuses do not have an alarm function, whereas electronic fuses generate an alarm.
• A combination of both systems is often recommended.
• Fuses made of hardened steel or reinforced metals are more resistant than simple plastic solutions.
• For outdoor areas (e.g. shutters), rust-proof materials such as stainless steel are advantageous.
• High-quality locking mechanisms should remain functional for years.
• Key-based systems increase security, but can be impractical.
• Automatic or smart solutions offer more convenience, but require a power supply or batteries.
• An inexpensive product is not always the best choice. The decisive factor is the ratio of acquisition costs to security gain.
• High-quality window locks can prevent high repair costs due to burglary damage.
• Availability and delivery time are particularly relevant for large orders for commercial or residential buildings.

By taking these criteria into account, secure, economical and user-friendly window locks can be professionally selected.
