A conservatory or orangery is one of the most transformative home extensions you can invest in, flooding your living space with natural light, adding value, and creating year-round comfort.

But what makes a glazed structure truly exceptional?

It all starts with selecting the best materials for a conservatory or orangery. From beautiful oak frames to modern aluminium, your choice of structure and glazing will impact everything from style to energy efficiency.

At Hallmark Glazed Extensions, we’ve guided homeowners across the country through these decisions, creating bespoke spaces that enhance both lifestyle and property.

Here, we help explain the different frame options and glazing types, using real-life case studies to show what materials are possible for your conservatory or orangery.

Premium Frame Materials: What Are the Differences?

1. Oak: Classic, Cosy, and Timeless

Oak is synonymous with British craftsmanship. As a sustainable, renewable material, it brings undeniable warmth and elegance to any traditional conservatory or orangery. Its natural grain and golden hues make it a favourite conservatory or orangery frame for period homes and countryside retreats. At Hallmark Glazed Extensions we only use seasoned oak in the construction of all our oak orangeries, conservatories and garden rooms.

Case Study: For our client in the New Forest, we created a dual-lantern seasoned oak framed orangery. By reclassifying the build as a conservatory, we adhered to national park regulations, allowing a 75% glazed roof. It features an oak-framed lantern over a cosy lounge and an aluminium-framed lantern above a utility room. Using seasoned oak and solar control glass, the orangery harmonises with its natural surroundings while providing year-round comfort and light.

Benefits of Oak:

  • Excellent thermal performance for the winter months
  • Long lifespan with proper maintenance
  • Enhances natural light with its warm tone
  • Timeless design sympathetic to conservation or areas of outstanding natural beauty

2. Hardwood: Sturdy, Sophisticated, and Customisable

For those who would like timber frames but are not necessarily concerned with achieving the appearance of seasoned oak, Sapele offers an excellent painted alternative. It provides many of the same benefits as seasoned oak, including strength and durability, while offering design flexibility at a slightly lower price point. This makes Sapele an ideal choice for bespoke conservatory or orangery projects, especially on properties that blend traditional character with modern style.

Case Study: Mrs Gray’s hardwood orangery on a listed property, in Hampshire, shows how Sapele-inspired designs complement heritage architecture beautifully. This frame option is particularly suited to rural, detached homes where a traditional extension feel is essential.

Benefits of Hardwood:

  • High durability and strength
  • Paint or stain to suit your décor
  • Ideal for matching period features
  • Suitable for properties under conservation rules

3. Aluminium: Modern Aesthetics with Minimal Maintenance

For homeowners looking for a modern look, aluminium is a great choice. It’s lightweight yet incredibly robust, allowing for slimline frames that let in more light and give a crisp architectural feel.

An aluminium conservatory or orangery is not only energy efficient thanks to integrated thermal breaks, but it’s also highly durable and virtually maintenance-free.

Powder-coated finishes in white, black, or popular Anthracite Grey give you the freedom to style your frame as you like.

Case Study: A bespoke aluminium-framed conservatory built for Mr Hook in Surrey showcases how this material delivers sleekness and functionality. It not only blends seamlessly with his existing home, but also creates the perfect space for both relaxation and entertainment.

Benefits of Aluminium:

  • Ultra-slim frames for maximum large windows
  • Resistant to corrosion and wear
  • 100% recyclable – eco-conscious
  • Ideal for glazed roofs or flat roofs with roof lanterns

4. uPVC: Affordable, Practical, and Surprisingly Stylish

If you're seeking a budget-friendly solution without sacrificing quality, uPVC is worth considering. It’s one of the most sustainable construction materials due to modern recycling techniques and offers long-lasting performance.

Available in different foil colours, such as white or Anthracite Grey, uPVC suits both modern and traditional properties alike.

Case Study: A uPVC LivinRoom conservatory in Hailsham, East Sussex proves that with thoughtful design, this standard material can look anything but basic. It has created a garden room using stylish Anthracite Grey uPVC frames, equipped with solar glazing that allows natural light in while keeping the room warm in winter and cool in summer.

Benefits of uPVC:

  • Affordable and lightweight
  • Strong, weather-resistant frames
  • Colour-flexible for a custom finish
  • Great for homeowners seeking value

Understanding Glass: What Glazing is Best for a Conservatory or Orangery?

Glazing plays a huge role in the performance and look of your conservatory or orangery.

Choosing the right type of glass can ensure that your home extension remains comfortable throughout the year, keeping it cool in the summer and warm in the winter. These factors are essential for usability and overall comfort.

Top Glazing Options to Consider:

  • Solar Control Glass – Reduces heat build-up during sunny days, improving comfort.
  • Low-E Glass – Boosts energy efficiency by retaining heat.
  • Self-Cleaning Glass – Uses sunlight to break down grime, making maintenance easier.
  • Toughened Safety Glass – Breaks into blunt pieces for added safety.
  • Laminated Glass – Ideal for sound insulation and extra security.

Combined with a fully glazed roof or a roof lantern, these options provide a stunning visual impact while enhancing your home's overall performance. Whether you opt for a traditional conservatory or a more contemporary orangery, your glazing choices affect both form and function.

  • Budget: Higher-end materials like seasoned oak offer long-term value, while uPVC delivers quality at a more accessible price point.
  • Regulations: Listed or conservation properties may restrict certain frame choices. It’s always best to consult local building regulations.
