Ask the expert: Solving glazing, energy and design challenges in homes across Norfolk hero

Got a design or glazing conundrum? We asked Geoff Parker, Managing Director of Which? Trusted Trader–accredited West Norfolk Glass, to share his expert insights on energy efficiency, listed buildings, conservatories, and modern interior design trends. Here’s what he had to say...

Will new double glazing reduce my energy bill?

With energy costs continuing to rise, improving the efficiency of our homes has never been more important. The UK currently has the least energy-efficient housing stock in Western Europe, and outdated windows are a major contributor.

In fact, upgrading homes with modern double glazing could reduce UK carbon emissions by 5.96 million tonnes per year, the equivalent of taking 3.54 million cars off the road.

It’s estimated that 98% of existing windows don’t meet current building regulations for energy efficiency. By replacing glazing installed before 2002, the average household could save around £395 per year on heating bills.

Modern double glazing performs:

  • 50% better than older double glazing
  • 70% better than single glazing

Triple glazing can improve performance even further, making it an excellent option for those seeking maximum efficiency.
 

I have a Grade II Listed house – How can I improve Its energy efficiency?

The first step is always to contact your local authority and speak with a conservation officer. Any work that affects the character of a listed building requires formal consent.

In some cases, heritage-style or slimline double glazing may be permitted. These options are designed to be discreet while improving thermal performance.

If double glazing isn’t allowed, secondary glazing is an excellent alternative. It can:

  • Improve thermal efficiency by up to 65%
  • Reduce noise levels by up to 80%

This makes it a popular and effective solution for historic homes.

My conservatory is freezing in winter and too hot in summer – Do I need to replace it?

Many homeowners inherit a conservatory expecting extra living space, only to find it unusable for much of the year. Poor insulation often leads to extreme temperatures and condensation during winter months.

The good news? A full replacement isn’t always necessary.

Installing a replacement solid roof can completely transform a conservatory into a comfortable, year-round living area. After assessing whether the existing structure can support it, a solid roof can:

  • Dramatically improve thermal performance
  • Reduce condensation
  • Minimise external noise

Homeowners are often surprised by just how much quieter and more comfortable their conservatory becomes.

We love open-plan living but want to zone the space – what do you suggest?

Open-plan layouts are hugely popular, but defining different zones within one large space can be challenging.

A growing trend is internal glazing, also known as “broken plan” design. This approach allows you to divide areas without sacrificing natural light or a sense of openness. Aluminium-framed internal glazing is particularly popular thanks to its:

  • Contemporary appearance
  • Minimal sight lines
  • Versatility

From home offices and snugs to dressing rooms and pantries, internal glazing offers endless possibilities for stylish and practical zoning.
