The role of high-performance glazing in new-build developments

Key takeaways

• High-performance glazing supports energy efficiency, compliance and aesthetics in modern new builds
• Double and triple glazing helps reduce energy costs and improve EPC ratings
• Compliance with the Future Homes Standard requires glazing that meets updated building regulations
• SGC Glass supplies and installs fully compliant, bespoke systems across London, Essex and Surrounding areas

In today’s construction environment, high-performance glazing is no longer a luxury – it’s a necessity. Whether you’re a developer working to meet the Future Homes Standard or an architect designing a standout new build, glazing plays a central role in shaping energy efficiency, regulatory compliance and overall thermal performance from the outset.

At SGC Glass, we support developers, contractors and architects across London, Essex and surrounding areas with bespoke, regulation-ready glazing solutions tailored to new-build developments. This blog explores the key benefits of high-performance glazing, the latest requirements, and what to consider when specifying for long-term performance.

Why does glazing matter in new-build homes?

Glazing accounts for a significant proportion of heat transfer in a property. In fact, poorly insulated windows can be responsible for up to 25% of total heat loss in a typical UK home. In new builds, where compliance with energy efficiency and sustainability standards is non-negotiable, high-performance glazing ensures each home is built for the long term.

Key benefits of high-performance glazing in new homes include:

• Improved thermal insulation and reduced heat loss
• Lower energy costs and reliance on heating
• Compliance with current building regulations and the Future Homes Standard
• Increased natural light and occupant comfort
• Long-term energy performance certificate (EPC) improvements

Supporting compliance with updated building regulations

The 2022 building regulations update introduced new thermal performance requirements for both dwellings and non-dwellings. For glazing, this means stricter U-value targets, improved airtightness, and a greater focus on sustainable materials and ventilation strategies.

High-performance double glazing is the minimum standard, with triple glazing often required to meet thermal efficiency thresholds in new build homes. Products from SGC Glass are designed to meet or exceed these regulations, helping you achieve compliance without compromising on design or timelines.

From specification to installation: What to consider

Choosing the right glazing solution from the outset saves time and cost further down the line. When specifying for new-build developments, we recommend evaluating:

1. Thermal performance

Modern double and triple glazed units use Low-E coatings, argon gas fillings, and warm edge spacers to reduce heat transfer. These technologies work together to deliver better insulation and more stable indoor temperatures throughout the colder months.

2. Frame material

Aluminium frames remain a popular choice for developers due to their durability, slim profiles and recyclability. Our aluminium windows are thermally broken to ensure high thermal performance without sacrificing style

3. Solar control and coatings

For developments with large glazed areas or south-facing façades, we offer specialist solar control coatings to minimise overheating risk and maintain comfortable indoor conditions year-round.

4. Ventilation strategy

Glazing must work alongside the building’s ventilation system to meet airflow and moisture management needs. We offer compliant trickle vent options and advise on integrating passive design principles.

How does high-performance glazing lower energy bills?

Efficient windows reduce the need for artificial heating and cooling by maintaining stable indoor temperatures. This leads to less energy consumption, fewer carbon emissions, and better EPC ratings for your developments. Over time, homeowners benefit from noticeably lower energy bills – a key selling point in today’s cost-conscious market.

Supporting long-term sustainability goals

SGC Glass is proud to support sustainable construction practices across the UK. Our solutions play a part in helping developers meet long-term sustainability targets, including:

• Reducing carbon emissions in line with UK climate goals
• Minimising waste through high-quality, long-life products
• Supporting Future Homes compliance and zero-carbon aspirations
• Delivering durable glazing that reduces the need for future renovations or retrofit projects

What type of glazing is best for new-build developments?

High-performance double glazing is suitable for most new builds, though triple glazing is increasingly specified in colder regions or to meet ambitious energy targets. Our team helps you assess which option will meet the thermal performance requirements of your specific project without over-specifying.
