Secondary Glazing vs Modern Steel Windows: Benefits & Considerations

With winter firmly upon us and the price of fuel rising again, homeowners  – particularly those in older or period homes – are having to weigh up their options when it comes to window replacement.

Swapping older single-glazed windows for their modern equivalent simply isn’t a good idea. Fuel prices only seem to be going one way, and single glazing is no ally in the fight against climate change and fuel efficiency.

There is the option of secondary double glazing. This involves installing an additional window pane inside existing frames, creating an extra barrier against heat loss and draughts. This solution can preserve original windows while improving insulation and it’s often considered a cost-effective option, particularly for listed buildings where replacement isn’t permitted.

However, secondary glazing comes with limitations. Condensation can develop between panes, maintenance becomes more complex and the overall aesthetic may impact your interior decor.

The modern Crittall glazing solution

Many homeowners don’t realise that Crittall’s contemporary steel windows offer superior performance without compromising the classic aesthetic they love. Today’s Crittall windows are far removed from their single-glazed predecessors, featuring highly advanced double glazing and thermal break technology.

The Corporate W20 windows, for example, provides excellent thermal performance that more than meets current building regulations. These modern steel windows retain the slim profiles that Crittall is renowned for while delivering impressive energy efficiency. So much for rising heating costs!

Unlike alternative materials such as uPVC or basic shutters, modern Crittall metal windows provide an authentic solution that combines heritage appeal with contemporary performance. They’re engineered specifically for different styles of property, offering various options to suit both traditional and modern architecture.

The Investment Perspective

Though the cost of replacement might initially seem significant compared to secondary glazing, it’s important to consider the long-term benefits. Modern Crittall windows offer superior thermal efficiency, reduced maintenance requirements and enhanced property value—making them a sound investment for discerning homeowners. They can also be made to your exact requirements and tastes.

Key Considerations

Energy Efficiency:

• Modern Crittall windows feature sophisticated thermal breaks and double-glazed units
• Secondary glazing offers improved insulation but typically can’t match the performance of new units

Aesthetics:

• Contemporary Crittall designs maintain original sight lines without additional frames
• Secondary glazing adds extra window furniture and can affect the clean lines of your property

Maintenance:

• New installations require standard care routines
• Secondary systems mean maintaining both original and additional window types

Long-term Value:

• While the initial cost of replacement windows may be higher, they offer a comprehensive solution
• Secondary glazing represents a compromise that may need revisiting
