WinterGardenz 6mm twin-wall polycarbonate greenhouses are the best polycarbonate greenhouses on the market.  We only use the highest-quality polycarbonate that is UV-coated on both sides.  Backed with a 10-year warranty, you don't have to worry about panel blowouts or broken panels.  While poly won't last forever like our toughened safety glass, it does have other benefits like better thermal insulation and protection from harsh UV rays.  Polycarbonate is also a little easier on the wallet.  With 21 different kitset sizes to choose from, we can help you find the perfect size greenhouse to get you growing!
