Insupolycarbonate™ conservatory roofs have been developed through a collaboration between Insu™, the UK's leading supplier of transparent heat reflectors for glazing applications, and Polytec, a principal supplier of polycarbonate roofs to the trade in the UK and Europe.

Insupolycarbonate™ roofing incorporates transparent heat reflectors on the inside surface of the outer wall of the poly-carbonate, to exclude 80% of the sun's heat and exclude glare.

Traditional conservatory Heat Stopper technology can, at best, only exclude 45% of the sun's heat. This is inadequate as the minimum for an effective solution is 65% solar heat rejection for normal conservatory roof heights, rising to 75% in low lean-too conservatories typically fitted to bungalows.

The best internal conservatory blinds have limited performance because the sun's heat is already inside the conservatory before it reaches the blind and the conservatory is just as effective at conserving heat in the summer as in winter. This means that once the heat is inside the conservatory it is extremely difficult to get it out.

Insupolycarbonate™ roofing excludes 80% of the sun's heat before it enters the conservatory roof – far surpassing the performance of any other product. It achieves this high performance by reflecting the sun's heat out before it enters the roof, and therefore provides solutions to the most demanding problems of overheating and glare.

Based on Macrolux™ five wall poly-carbonate it is available from Polytec, or direct from Insu™. All physical properties, fixing details, and other aspects of installation are identical to the Macrolux™ product. Full details are available on request.

Design services

At Insupolycarbonate™ roofs we are committed to assisting conservatory suppliers and domestic conservatory customers with design information on the use of our products to achieve maximum comfort in their conservatories.

This service assesses the following aspects:
Ventilation , and the correct positioning of windows, and roof-lights to ensure that the conservatory has good ventilation and temperature control, at the minimum window/roof-light cost.

Temperature and cooling load reductions that can be achieved through the use of our products. In large domestic and commercial installations it is necessary to work with heating and ventilation engineers to establish savings in air-conditioning and ventilation costs, and the reduced capital cost of equipment that can be achieved through the use of our product.

Heating needs and the adequacy of existing, and new boiler/heating capacity. A major problem in conservatories is the correct calculation of the capacity of the radiators needed, whether or not existing boiler capacity is adequate, and the size of any new boilers.    Because plumbers have no suitable calculation tables for the heat loss factors in conservatories they have to rely on calculations used for domestic rooms. As heat losses in conservatories are of a completely different scale insufficient radiator capacity is often installed. This means that the conservatory is unusable in winter, early spring, and late autumn.
    Boiler capacity can also be a problem. If no account is taken of the extra boiler capacity required to heat the conservatory, and radiators are simply added at the end of the line, the boiler may be unable to cope with the extra demand. Again the conservatory will be unusable in winter, early spring and late autumn, and the heating in the house may also suffer.
    It is most important that an accurate assessment of the heating requirements in the conservatory is made. Not only to ensure that the radiators are adequate, but most importantly to check if a new higher capacity boiler is required.
