Trickle Vents, Restrictors and Glass Markings for Clement Steel Windows, Doors and Screens
Trickle vents are small openings in a window which allow some ventilation when the windows are closed.
The trickle vent can be set into the timber sub-frame or into the steel window frame, depending on the exact specification of your project. Trickle vents can be coated in a polyester powder coat paint to match your windows.
Restrictors are available to prevent windows from opening too far in situations where safety or security is a particular priority.

Glass Markings
Please note that while most windows will not require one, a visible safety mark will appear on each individual pane of glass on door products or where safety glass is required. This is a requirement of Building Regulations and customers would need to seek building control dispensation in writing, in order for Clement to remove this.
