Insulating a Conservatory Roof: A Good Idea?

Insulating a conservatory roof is becoming an increasingly popular home improvement, as homeowners look to extend the use of this space throughout the year. Conservatories can be a lovely addition to any home with a view; the idea is that they provide a warm, comfortable place to enjoy the sunshine and admire your surroundings. The problem is they do not always match up to expectations. 

Anyone with a greenhouse in their garden knows that sun shining through glass makes the interior very warm. A conservatory is the same. Likewise, the very best double glazing is less than half as good as a wall at keeping warmth in, so a conservatory might get too cold for comfort in winter.

He is the author of The Sustainable Building Bible, Simply Sustainable Homes and Anaerobic Digestion - Making Biogas - Making Energy: The Earthscan Expert Guide.

His interest in renewable energy and sustainability was first inspired by visits to the Royal Festival Hall heat pump and the Edmonton heat-from-waste projects. In 1979

this initial burst of enthusiasm lead to him trying (and failing) to build a biogas digester to convert pig manure into fuel, at a Kent oast-house, his first conversion project.

Moving in 2002 to a small-holding in South Wales, providing as it did access to a wider range of natural resources, fanned his enthusiasm for sustainability. He went on to install renewable technology at the property, including biomass boiler and wind turbine.

He formally ran energy efficiency consultancy WeatherWorks and was a speaker and expert at the Homebuilding & Renovating Shows across the country.
