Lift out Secondary Glazing 

 
 
 
Lift-out windows, also known as removable windows, typically tilt outwards from the top only. They cannot be opened from other sides, making them a popular choice in office buildings where minimal opening is sufficient. 
 
Lift-out secondary glazing offers several benefits, including: 
 
The removable feature allows for straightforward cleaning and servicing 
Limited opening restricts access, providing better security 
Improved insulation: Adds an extra layer of thermal efficiency 
Effective in minimising external noise 
Ideal for applications where limited window operation is needed

Lift out Window Installation  

Lift-out secondary glazing is installed by fitting a secondary glazing unit that can be easily removed or lifted out of the frame when necessary. The installation process ensures that the secondary glazing complements the existing lift-out window, providing enhanced insulation and performance. 
 
When used with secondary glazing, lift-out windows benefit from improved insulation and noise reduction while retaining their removable feature. The secondary glazing enhances the overall efficiency of the window system without interfering with its lift-out functionality, making it ideal for office environments and other settings where limited window opening is required.
