Enduring conservatories in Buckinghamshire, Hertfordshire & Oxfordshire

Conservatories 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.

Outstanding Service

We had many issues trying to locate a company to replace our conservatory roof however, this company was recommended to us by a friend of a friend and we couldn’t be happier. It was really refreshing to have a company not place any pressure for a sale; always available to answer any queries; worked incredibly quick and professionally throughout with a friendly manner. We are so impressed with the service received, that we have now booked them again in May to have our windows replaced.

‘Double Glazing Direct’ were brilliant.

They were extremely polite and professional. Before they started the work on the day of installation, taking out the existing windows, they prepared the area with dust sheets and special protective flooring on our wood floor and stairs. The fitters were skilled knowledgeable and focussed. There was no mess made during the installation. The quality of the product and installation was excellent. I love my windows and I will always recommend ‘Double Glazing Direct’.
