​

What Is Slimline Double Glazing?

Slimline double glazing uses a narrow 12mm cavity between glass panes, allowing heritage-style timber frames to accommodate modern insulation standards. It provides excellent thermal and acoustic performance while maintaining the delicate proportions of traditional sash and casement windows—perfect for listed and conservation homes in Manchester.

 

Why Manchester Homeowners Choose Slimline Double Glazing

In Manchester’s many period and Victorian homes, maintaining original window design is essential. Slimline double glazing is an approved and trusted solution for properties where standard double glazing may not meet planning or aesthetic requirements.

 

Benefits of Slimline Double Glazed Sash Windows

 

Preserve Historic Character

Our slimline glazing units replicate traditional single glazing from the outside while offering superior insulation. Each frame is handmade to match original mouldings, ensuring an authentic look that satisfies conservation officers.

 

Improve Energy Efficiency

Slimline units reduce heat loss and condensation, delivering up to 60% better insulation than traditional single glazing. Enjoy a warmer, quieter home without altering its heritage design.

 

Perfect for Conservation Areas

Many local authorities in Manchester approve slimline glazing for listed and conservation properties because of its subtle appearance. We handle the entire process, from design consultation to installation, ensuring compliance with planning guidelines.
