Ultimate guide to double glazed sash windows London

London’s historic charm is undeniable, with its beautiful period architecture showcasing timeless features like wooden sash windows. But while these windows bring elegance and character, they also come with challenges. Keeping that classic look while meeting today’s energy efficiency standards can feel like walking a tightrope. That’s where TRC Contracts steps in.

With years of experience, we specialise in blending the old with the new – restoring and upgrading original sash windows or creating bespoke replacement sash windows that retain their heritage charm while bringing in modern comfort and performance.

A look back at sash windows in London

From the stately elegance of Victorian sash windows to the more minimalistic designs of Georgian and Edwardian eras, sash windows are a defining feature of London architecture. These traditional timber sash windows have stood the test of time, but as the city evolved, so did the demands on these iconic features.

Property owners today want more than just aesthetics – they want new windows that reduce energy bills, block out noise pollution, and still preserve the classic style of window their building was built with. It’s a tall order, but one we’re passionate about fulfilling.

Why double glazed sash windows are a popular choice

If you’re thinking about upgrading old sash windows for your next project, double glazing offers the best of both worlds. Here’s why so many architects and specifiers choose it:

  • Better energy efficiency: Advanced glazing and snug draught seals keep the warmth in and the cold out, helping cut down on heating costs.
  • Reduced noise pollution: London can be noisy, but double glazing – especially with acoustic panes of glass—helps keep the hustle and bustle outside where it belongs.
  • Heritage aesthetics with modern performance: We craft new sash windows to replicate the original sash window profile, ensuring your project retains its historic charm.

Whether it’s for a single room or a complete sash window replacement, our high-quality materials and craftsmanship ensure our windows perform as beautifully as they look.

Options to suit every building

At TRC Contracts, we understand that no two buildings are the same. That’s why we offer a variety of types of windows, designed to meet your needs while respecting your project’s character:

  • Wooden sash windows: For those who want to preserve their property’s original charm with high-performance upgrades.
  • Timber casement windows: A versatile option for both heritage and modern properties.
  • Replacement sash windows: A perfect solution for upgrading old windows without compromising their traditional appeal.
  • New windows: Bespoke designs tailored to your property’s unique architectural style.

Whatever the project, our focus is on delivering exceptional quality, from the timber frame to the glazing.

Working with conservation areas and listed buildings

If your property is in one of London’s many conservation areas, or even listed, the rules around upgrading your windows can be tricky. Luckily, our team has years of experience working within these guidelines. We craft traditional timber windows that meet strict planning requirements while delivering the energy efficiency and comfort to meet today’s modern needs.

Whether your project is in Kensington, Camden, or other areas of London, our expertise ensures it complies with building regulations while staying true to the original design.

The benefits of modern sash windows

Upgrading existing sash windows isn’t just about improving their look. Modern double glazed wooden windows offer real, tangible benefits:

  • Lower energy bills: Advanced glazing drastically reduces heat loss, keeping your property warm in winter and cool in summer.
  • Peace of mind: Our windows meet or exceed building regulations, so you know you’re making a future-proof investment.
  • Durability and performance: With proper care, timber windows can last for decades.

And because we believe in doing things right, every window we install is designed with best practices in mind, ensuring it fits seamlessly into your project’s architecture.

Our process: High quality from start to finish

Whether it’s a single window or a full-building installation, our sash window installation process is designed to be smooth and stress-free. We’ll guide you every step of the way, from choosing the right style of window to fitting them with precision.
