Often referred to as a Wintergarden, Glass Extension, Glass Boxes or Sunroom, Glass Rooms come in aluminium or a combination of timber and aluminium with some systems. They come either fixed to the home and extending the room or as a free-standing structure in the garden. Using thermally insulated aluminium and high specification insulated glass, these modern glass rooms offer all the benefits of an all-year-round room with excellent energy efficiency, acoustics and interior comfort.

Of course, the benefit of glass rooms and glazed extensions is their full integration with virtually any type of bifolding doors, sliding doors and modern aluminium windows. With large span doors, these fully open up the room like a familiar extension, connecting to the garden seamlessly.

For those projects where a fully insulated system is not required, options exist for aluminium and hybrid structures using single glazed products or non-insulated windows, doors and roof materials.

These come designed as a glass canopy to provide overhead protection from the rain and provide shade when fitted with an awning, or as a summer, garden or glass house when fitted with vertical glass panels which can be fully open in good weather or closed off fully/partially for protection from the wind and rain, while at the same time enjoying the outdoors and a fully unobstructed view of your garden.

Design and features of Glass Rooms and Glazed Extensions

With glass being a major material in the design and execution of glass rooms, there are substantial glass options available. Working with a professional designer of these products, options include sound and sun protection, enhanced security and shading. Designs also include self-cleaning glass, solar glass and a combination of glass and architectural panels.

Additionally, these glazed extensions come with options for climate control, manual or powered blinds and awnings. The bespoke nature of these quality glass structures provides design and product solutions for virtually any project requirement.

Light and a feeling of space mean using slimline aluminium profiles combined with contemporary doors and windows. Most systems offer their own collection of windows and doors. Every one of these is designed for standard designs, open corners, slide and turn systems, low thresholds and other essential design features.

With properties and gardens varying in size, aluminium glass rooms and glazed extensions come fully bespoke. From a basic glass canopy up to a substantial glass structure, the design of these products means any property size benefits from the added space provided by glass rooms and glazed extensions.

Importantly, the design of these structures comes with high specifications and certification for product quality, conformity, security and weather performance.

Conservatories and Orangeries

While traditional bolt-on conservatories remain available, tastes now particularly lean towards more modern and better-insulated structures.

In the same way as glass rooms, conservatories and orangeries consist of primarity glass. Therefore, they have the same temperature fluctuations as any glass structure, such as being colder in the winter and warmer in the summer. In spite of this, Orangeries come with more solid walls and structural elements and offer better interior comfort and heat retention than a conservatory.

The trend for PVCu Edwardian, Victorian and similar styles is less popular than previous years. However, many conservatory specialists now provide all manner of styles and designs, meeting customer requirements and budgets. Overall, the trends and homeowner requirements today remains one for an all-year-round-room wherever possible.
