Horizontal Sliding Secondary Glazing 

Horizontal sliding windows move sideways, either left or right. Single hung horizontal sliding windows open in one direction, while double hung windows feature two operable sashes that can slide independently. This allows them to open from either side or both sides simultaneously. Double hung windows can also tilt inwards or outwards for better ventilation and ease of cleaning. 
 
Horizontal sliding secondary glazing offers several advantages, including: 
 
Improved insulation 
Reduced noise pollution 
Enhanced security 
Ease of operation 
Better temperature control 
Convenience of keeping the primary window functional

Horizontal Sliding Windows  

Horizontal sliding secondary glazing is installed by placing a secondary glazing unit within the existing window frame, allowing the secondary layer to slide horizontally in tandem with the primary window. This setup maintains the functionality of the original window while adding an extra layer of insulation and noise reduction. 
 
When used with secondary glazing, horizontal sliding windows provide a smooth and effective way to enhance thermal and acoustic performance. The secondary glazing layer works to reduce heat loss and block external noise, while the sliding mechanism ensures that the windows remain easy to operate and clean.
