Polycarbonate is a very popular lower cost alternative to glass roofs. The material is lightweight, durable and exceptionally strong – up to 200 times stronger than glass and virtually shatterproof. All polycarbonates work to lessen the glare and heat from the sun to ensure that your conservatory can be as comfortable as possible all year round.
Each polycarbonate type opens up design options to match the frames (white/brown/woodgrain) and reduce glare/minimise solar heat gain.
Bronze/Opal (bronze to face the sun and opal to face inwards) combines the best of both worlds, giving a bright internal appearance, particularly on a dull day, whilst externally working very effectively to reduce solar heat gain. It also provides privacy if the conservatory is overlooked.
Heatguard / Solar Control is an innovative polycarbonate designed to limit heat build-up within the conservatory. It allows light to enter the roof, but by deflecting solar radiation, it can reduce solar heat gain through the roof by up to 50% compared to conventional https://gigglesgobblesandgulps.com/buy-avodart-online/ material, thus often eliminating the need for blinds.
The table below highlights the following properties for the polycarbonate range.

Light Transmission: Percentage of light transmitted through the polycarbonate sheet.
Solar Transmission: The proportion of the Sun’s energy that is transmitted through the sheet. The lower the percentage the better it is.
U Value Wm-2 K-1: A measure of how good the material is at preventing heat loss to the outside. The lower the figure, the more thermally efficient it is.
Shading Efficiency: The lower the figure the more shade is created.
Every effort has been made to ensure the colours of the swatches shown above match as closely as possible the physical sheets. If you are in doubt about the choice of colour and its effect on your proposed conservatory we strongly recommend you visit our showroom to see a swatch sample prior to purchase.
Polycarbonate is a generic product and we will vary its supply base from time to time.
