Why You Should be Interested in u-Values if You Have a Conservatory
u-Values relating to domestic and commercial buildings are simply a means of expressing how well heat penetrates a material, whether in or out. If you have a conservatory with a glazed or polycarbonate roof, you already know that it is simply too hot in the summer and too cold in the winter. Too much heat penetrates the conservatory roof in the summer, and too much heat is leaked out in the winter. Glazed or polycarbonate conservatory roofs are simply not thermally efficient.
A high u-value indicates that more energy/heat is lost and a lower u-value indicates that there is less energy/heat lost. Insulating your conservatory roof professionally with a suitable insulation provides huge benefits in terms of u-value and energy loss and has a lower ie better u-value than fitting conservatory blinds. If you are thinking of fitting conservatory blinds, you should check the u-value performance before parting with any money.
A new tiled replacement roof will provide the best u-value in terms of energy efficiency, however for many conservatory-owners the cost of replacing the roof can be more than the original cost of the conservatory and is simply not cost effective!
Most conservatory roofs in the UK are polycarbonate and typically, a 16mm polycarbonate conservatory roof will have a high u-value of around 2.4w m/2k. By fitting an inexpensive but thermally efficient insulated ceiling to your conservatory roof, the u-value can be reduced by 90%.
In simple terms you can save upto 90% of the heat lost through the roof in the winter, and block upto 90% of the sun’s heat from penetrating your conservatory roof in the summer. What this means in practice, is that your conservatory can have a much better temperature for more of the year as well as being a cost effective and elegant solution.
