In winter, late autumn, and early spring the sun is lower in the sky and predominantly shines into the conservatory through the windows. This typically releases about 4kw* of heat energy on a clear day. This valuable energy with a poorly insulated roof all but disappears into the atmosphere.
Insu can specify very high performance roofing solutions that has āUā values as low as 0.6 ā an insulated brick wall is measured at just 0.7 to 0.8. This is nearly 4 times better than a traditional double glazed or polycarbonate roof and 3 times better than the new building regulations stipulate! (insert thermal efficiency of cons roof glazing chart here)
Such insulation therefore traps the suns heat (and any artificial heat) in the conservatory. This means that either no or little extra heat source may be required in the conservatory to make it usable. However, on many days there will be a surplus of solar heat to warm the house.
The stored heat over and above that required to heat your conservatory can subsequently be released into the rest of your home by simply opening the patio or French doors. The heat will naturally flow around your home. The benefit of course is that you can turn down your thermostat at certain times of the day saving money on those ever increasing fuel bills and of course reducing your carbon footprint.
It can be loosely likened to solar energy panels but of course there's no expensive and complex piping, controls, installation etc. In comparison, the cost of upgrading to a more superior roof does not add significantly to the cost of your conservatory.
*depends on the size, design and aspect of the conservatory
