Solar Inserts for Polycarbonate Roofs

Insu have pioneered the solar insert concept. Our first patents dating from 1992, protect the channel shape heat reflector which has a flat top that covers the full width of the polycarbonate channel. This design provides unrivalled heat elimination as the solar heat is reflected out before it can enter the roof. The competition is restricted to using a thin metallised tape which has a dome top. This is much less effective as the dome shape deflects the sun's heat into the polycarbonate panel. The key to our product's exceptional performance is its unique patented channel shape. The flat top stops the heat before it can enter the roof. For comparison against other products click here.

Insu Solar Inserts – a cut above the rest!


The results are amazing – look at the benefits:

  • Cuts solar heat gain by 85% in summer and keeps heat in during winter and cold evenings. By keeping your conservatory environment cooler in summer and warmer in winter it means that your conservatory can be used comfortably for much more of the year. In general terms humans find conditions comfortable when temperatures are between 18 C (64F) and 28C (84F) and, as you can see by the typical graph, the time in the ‘comfort zone' is extended from 3 up to 8 months including the summer, when Insu solar inserts are fitted. What's more you will find that a more varied range of plants will not only survive but will positively thrive!


  • Insu solar inserts

  • Eliminates uncomfortable glare and maintains the special light and airy feel of your conservatory. Perhaps the best way to explain this feature is that the material acts like a pair of sunglasses. The inserts are totally transparent but because of the reflective tint properties they cut the glare to comfortable levels. It even makes watching TV or using a computer possible where before it would be almost impossible as the screen had to fight the glare.
  • Insu inserts cut UV levels through the conservatory roof by 99%! While any natural light will cause furniture and fabrics to fade the major factors are Ultra Violet light and solar heat. The eradication of the UV and reduction of solar heat by fitting Insu solar inserts will drastically slow the rate of fading keeping colours natural for longer. Of course much has been reported about the harmful effects the sun's UV rays have on the skin, with Insu inserts fitted the risk all but disappears.
  • Maintenance Free. As the inserts are fitted within the roof panel structure they can not suffer any damage and are fully protected from the elements. Unlike blinds, they won't attract dust and insects and won't fade and sag under the effects of heat and UV rays from the sun.
