Bespoke Glass Boxes

Glass Box extensions or Frameless Conservatories made form structural glass units and supported with glass beams and fins

Glass Box extensions or conservatories can create a completely clear, frameless extension space with no metal supports visible. By using frameless pieces of strong structural glass with laminated glass beams and fins the entire construction can be completely glass.

The full range of IQ’s technical glass solutions can be used within these frameless glass boxes for highly performing space. Heated glass can provide the sole heat source for the extension space, solar control coatings can provide effective solar protection and low maintenance coatings help lower maintenance and cleaning on these large frameless glass structures.

Frameless Glass Boxes

These types of frameless glass boxes can be used as both a conservatory and a glass extension depending on requirements. Using highly efficient double glazed, or triple glazed units these fully glazes structures can still be a comfortable warm environment with a thermal performance to adhere to Building Regulations for extension spaces.

Glass Box Extensions can integrate any number of access openings from our slim framed sliding door system, bi fold door sets, to bespoke flush glazed hinged doors and more.

The classic 'glass box' has undergone many developments over recent times including the move from single glazing to super-efficient double glazing, less metalwork and the introduction of oversize sliding doors with smooth operation.

A structural glass conservatory is one of the most popular glazed editions to homes across the UK. It’s easy to see why. With full integration of our heated glass, solar control coatings and contemporary sliding doors, we can create a modern space which you can inhabit all year round, whilst adding great value to your property.

Frameless Glass Box Extensions and Conservatories allow you to extend your house with an ultra-modern conservatory capable of bringing more light and space into your home whilst enabling you to enjoy your garden throughout each season.
