Polygal Polycarbonate use has greatly increased over the last few years, especially when it comes to roofing and window solutions. Even more so in greenhouse applications.
Polygal is known for toughness; it is virtually unbreakable. If you are tired of replacing your glass panels after a breakage, you may want to look for a better solution. Families with children know that a stray ball can do a lot of damage, as can flying branches in a gale, and flying debris in a storm.
Polygal twinwall polycarbonate retains heat extremely well, better than glass, and reduces the need for heating in winter. Furthermore, polycarbonate is good at maintaining an even temperature and keeping condensation to a minimum. Plants grow at a fast rate and the panels stand up well to cold weather. This is suitable for anyone concerned with having a long growing season.
Plants get an even distribution of sunlight as the light entering through twinwall is diffused, spreading it into every corner. Polycarbonate also lessens the risk of sunburn, filtering out most harmful ultra violet rays.

Polygal Polycarbonate is a tough, dimensionally stable, transparent thermoplastic that has many applications which demand high performance properties. This versatile thermoplastic maintains its properties over a wide range of temperatures, from -40"F to 280"F. It has the highest impact resistance of any Thermoplastic. Polygal is transparent up to 2" in special grades, has outstanding dimensional and thermal stability, exceptional machinability, and is stain resistant, non-toxic with low water absorption.
Polycarbonate greenhouses are the most popular form of garden building with enthusiasts and professionals alike looking for the best place to grow plants in a controlled environment.
Due to the insulating effects, polycarbonate greenhouses are fare more efficient at maintaining the internal temperature. This provides a better environment in which your plants can grow. Another factor that accounts for the popularity of this material is the way in which it diffuses sunlight. This means you will not have to provide as much shade for your garden plants when compared to traditional glass greenhouses.
Polycarbonate is less susceptible to breakage than glass. Numerous tests have been proved that the material is almost unbreakable. Test scenarios were carried out using rocks and wooden posts as projectiles in an attempt to break the polycarbonate panels, with no success.
Polycarbonate not only weighs less than glass but it also has a special UV coating that helps to protect plants growing inside the greenhouse from sunlight and extreme temperatures. The insulation characteristics of polycarbonate greenhouses means that plants will grow at a faster rate. Also, the ability to maintain a correct and constant temperature inside the greenhouse means you can grow plants all year round.

Polygal is unbreakable! We've had plenty of incidences where glass would have broken, but our Polygal panels keep our greenhouse safe and easily maintainable.

Thanks to the Interstate Plastics folks for helping me learn more about Polygal and using it to protect my skylights. Peice of mind during the windy season.

Not as visually appealing as the glass I was using, but I was tired of breakage, and so far so good with the new Polygal.
Marta Eklund, Nampa, ID
My plants respond better to the Polygal Polycarbonate than traditional glass. The light is dispersed, so all plants get even sunlight.
Linda Laoma, Cranston, RI
One of the sheets came damaged, and it took over 3 weeks to replace. The salesman did his best to correct the issue, but I was one sheet short for my schedulled and urgent project.

After the glass on the side of my greenhouse broke for the third time, I was desperate for a better solution. Interstate Plastic helped me pick the right Polygal kit, and not only do I have no more broken windows, but my greenhouse is visually stunning!
