Enduring conservatories in Aylesbury, Buckinghamshire, Hertfordshire & Oxfordshire

Conservatories Aylesbury of the past have often suffered from poor insulation, making them too cold to use in winter and far too hot throughout the summer months. Thanks to advances in construction materials, this is certainly not the case today. Our conservatories, veranda extensions, and orangeries are built with today and tomorrow's energy efficiency targets in mind. Notable energy saving features of our extension products include:

  • Our uPVC conservatories are capable of achieving impressive A+ energy ratings & U-values as low as 0.8 by upgrading to the 6 chambered Liniar EnergyPlus range.
  • Our aluminium verandas & orangeries provide outstanding weather resistance and feature an innovative, ultra-insulating polyamide 'thermal barrier' element; keeping bills low and satisfaction high.
  • Combining three fantastic layers of insulation, with the option to add illuminating roof lights, the ultra-efficient Guardian Tiled Roof System is capable of achieving industry leading U-values of just 0.18.
  • Designed to capture natural light from all angles, thermally efficient uPVC or slender aluminium lantern roofs are also available.

Combined with durable, high-quality window and door locking mechanisms, supplying and installing affordable, weather-resistant, and secure glazed extensions and refurbishments is what we do best.
