Choosing the right glazing option is essential for protecting and enhancing stained or leaded windows. Whether you own a period property or a listed building or have installed new windows, the right glazing will improve insulation, increase security, and preserve your window’s character.

At Sherriff Stained Glass Specialists, we offer expert window glazing services to suit all property types. In this blog, we’ll explain the three main glazing options available and how each can benefit your windows.

Secondary Glazing

Secondary glazing involves adding an internal layer of glass alongside existing windows. It’s ideal for if you want to preserve original stained or leaded glass windows without altering the external appearance of your property.

By fitting secondary window glazing, you can discreetly improve insulation and reduce draughts, helping retain warmth during colder months. It also increases security and provides extra protection against accidental damage, all while maintaining the visual integrity of period windows.

By opting for secondary window glazing, you can:

  • Enhance insulation, reducing heat loss and draughts.
  • Deter break-ins and protect against accidental damage.
  • Maintain the external appearance of your property, which is ideal for conservation areas.

Our team of window specialists at Sherriff offer bespoke secondary glazing solutions tailored to both residential and commercial buildings.  

Triple Glazing

With triple glazing, the window glass is sealed between two panes of clear toughened glass, creating a durable encapsulated unit. This method is particularly suitable for new stained glass installations or windows requiring robust long-term protection.

The key benefits of triple glazing include:

  • Improved sound and thermal insulation.
  • Easier maintenance, as the stained glass sits safely within the sealed unit.

Our specialists are highly experienced in incorporating triple glazing into both modern and traditional window settings for stained and leaded glass windows.

Conservation Grade Double Glazing

For historic and listed buildings, we offer conservation grade double glazing. This specialist glazing is designed to meet the specific requirements of heritage properties, preserving the original character and value of windows while discreetly improving insulation.

Conservation grade double glazing uses carefully crafted slimline units that replicate traditional glazing profiles. This allows period windows to retain their authentic appearance while enhancing energy efficiency. It also helps meet planning regulations for conservation areas and listed buildings.

Advantages of conservation grade glazing include:

  • Improving energy performance discreetly.
  • Compliance with conservation regulations and planning approval processes.

Sherriff Stained Glass Specialists regularly work with architects, heritage consultants, and private clients to fit conservation grade double glazing that balances preservation with performance.

Finding The Best Glazing Solution for Your Windows

Whether you are looking for discreet secondary glazing, protective triple glazing, or sensitive conservation grade double glazing, choosing the right option depends on your building’s age, style, and specific needs.

Choosing the right glazing option for your windows depends on several factors:

  • The type and age of your building.
  • Whether your windows are listed or in a conservation area.
  • Your priorities in terms of insulation, security, and preservation.

At Sherriff, our window specialists will always carry out detailed assessments to recommend the most appropriate solution, ensuring a balance between safeguarding your stained or leaded windows and enhancing their practicality.
