We’ve installed thousands of windows over the last 37 years, take a look at what we have installed more recently.
Whatever look you are going for with your home, there is a colour choice type to match, with a huge range of styles and decorative finishes available.
We’ve worked with hundreds of homeowners across Midlothian, from Dalkeith and Bonnyrigg to Loanhead, as well as throughout Edinburgh and the surrounding areas. With every project, we aim to exceed expectations, delivering glazing solutions that balance aesthetic appeal, thermal performance, and long-term durability.

Our range of products includes everything from traditional sash and case designs to sleek UPVC windows in Edinburgh and surrounding areas. Whether you prefer a classic look or something modern and minimal, we’ll help you find the ideal glazing option for your glazing needs.
We supply and fit casement windows in a wide range of styles and finishes, offering excellent ventilation and clean lines that suit both modern and traditional properties. Our UPVC windows provide an energy-efficient, low-maintenance solution that continues to be a favourite for homes across Edinburgh and Midlothian.
In addition to windows, we install composite doors that combine insulation, security, and visual appeal. For those looking to open up their living space, we also offer patio doors, French doors, and bi-fold doors, all designed to bring in natural light and create a seamless indoor-outdoor connection. If you’re thinking of expanding your living area, our conservatories offer year-round comfort and can be styled to match your existing home. We also provide high-quality glazed units and replacement windows that allow you to retain the look of your current fittings while improving performance and efficiency.
Every one of our windows and conservatories is designed and manufactured to meet current building standards, helping you reduce heat loss, lower energy bills, and improve your property’s overall energy efficiency.
Finding a reliable double glazing company can feel like a challenge, but The Advanced Group stands out in the glazing industry for quality, reliability, and service. We’re proud to be one of the leading double glazing names across Edinburgh and Midlothian, known for our energy efficient products, experienced glaziers, and a team of fitters committed to delivering lasting results.
As a trusted local glazing company, we’ve helped thousands of homeowners with everything from small glazing repairs to full-house installations of energy rated windows and doors. Each project is handled with care, attention to detail, and a commitment to delivering the highest standard of workmanship.
One of the most sought-after benefits of installing new windows is the improvement in energy efficiency. All of our double glazed windows are made to help reduce heat loss, using A-rated glazing with argon gas-filled cavities and advanced spacer technology. These features keep warm air inside during the colder months and help maintain a comfortable temperature all year round.
Whether you choose double or triple glazed units, each is designed with both energy efficiency and security in mind. Our range includes triple glazed units for added insulation and soundproofing, ideal for busy streets or areas exposed to the elements. These products not only help to improve energy efficiency but also support lower energy bills and a reduced carbon footprint.
If your current windows are showing signs of wear, feel draughty, or simply don’t suit the style of your home anymore, it may be time for an upgrade. Our team specialises in replacing old windows with energy efficient double glazing, tailored to your property’s style and performance needs.
We offer a wide variety of design options, including sash and case styles that preserve the period charm of older homes, and modern casement frames for sleek, minimal lines. Tilt and turn windows are ideal for easy cleaning and flexible ventilation.
Each replacement window is precisely measured and installed by experienced glaziers to ensure an exact fit and smooth operation, improving thermal performance and making your home more comfortable throughout the year.
Your choice of doors plays just as much a role in energy performance and security as your windows. That’s why we offer a full selection of composite doors, UPVC doors, and aluminium bi-fold doors, all of which are designed with energy efficiency and durability in mind.
Our doors feature high-performance glazing, solid construction, and a range of security features, including reinforced locks and weather-resistant seals. Whether you’re replacing an outdated front door or installing stylish patio doors to connect your home with your garden, you can count on The Advanced Group to deliver products that perform as well as they look.

Energy efficiency comes built into our window units. Their clever multi-chamber design helps trap heat inside your Midlothian home, cutting down on heat loss and helping you save on energy bills over time.
All of our windows come fitted with advanced heat-reflective glass, specially designed to improve insulation and maximise energy efficiency. It’s this built-in technology that helps our units achieve an impressive ‘A’ energy rating.
