Window locks and restrictors: child safety and easy airing

A safe window is not only sound joinery but also well-chosen hardware. Window locks and opening restrictors raise safety in the home, protect children and make airing rooms both convenient and safe. In this post we explain how the various solutions differ, how to choose between them and where each one earns its keep.

Lock or restrictor: what is the difference

The two words are often used interchangeably, but there are two distinct functions. A restrictor controls how far the sash opens, letting you set a safe angle, for airing say. A lock, on the other hand, guards the window against being opened fully or against being opened by anyone who should not, children included. Some products combine both functions and add burglary protection on top.

Protecting children

In homes with small children, window restrictors and locks are among the basics of safety, above all on upper floors. They let the window open only a small, safe amount, or stop a child opening it at all. Models operated by key or push-button give parents full control while still allowing the window to be opened quickly when needed.

Convenient, safe airing

A restrictor holds the window in a steady airing position, with no risk of the sash slamming in the wind. It is a convenience day to day that protects both the window and the household. There are light plastic restrictors with a dozen or more opening positions and solid metal models, including versions that lock with a key.

The kinds of solution available

In practice you will most often meet:

• light plastic restrictors with many opening positions, in white and brown,
• metal restrictors that can be secured with a key or a padlock,
• reinforced models with an anti-burglary function, operated by key or push-button, in several colour finishes.

The choice depends on whether the priority is convenient airing, child safety, or extra protection against burglary.

Where they are used

Locks and restrictors are used not only in houses and flats but also in schools, hospitals, care homes, offices, public institutions and hotels. Anywhere that controlled, safe opening of windows matters.

How to pick the right model

When choosing, take into account the type of window and how it opens, the function you need - airing, child safety or burglary protection - and a colour that matches the joinery. Fitting is quick for most of these and does not interfere with the profile’s structure.
