What is Double-wall polycarbonate
Rigid double-layer plastic sheets of acrylic or polycarbonate are available to give long-life, heat-saving covers. These covers have two layers of rigid plastic separated by webs. The double-layer material retains more heat, so energy savings of 30 percent are common. The acrylic is a long-life, nonyellowing material; the polycarbonate normally yellows faster, but usually is protected by a UV-inhibitor coating on the exposed surface. Both materials carry warranties for 10 years on their light transmission qualities. Both can be used on curved surfaces; the polycarbonate material can be curved the most. As a general rule, each layer reduces light by about 10 percent. About 80 percent of the light filters through double-layer plastic, compared with 90 percent for glass.
When will my greenhouse kit arrive?
You should expect to receive delivery within 10-14 business days in the 48 contiguous states unless otherwise noted.
Please Note:
On larger greenhouses, and other items that ship by freight, the
purchaser is responsible for getting the items off of the delivery
truck. We recommend you have at least 2-4 people to help you remove your
items. The driver is not responsible for removing the packages. Also,
some freight trucks are not able to deliver up your driveway. You are
then responsible to remove the items and transport them by other means,
carry them or by pick-up truck, to your house.
Tell me more about using my credit card to make a purchase?
Your credit card will be billed at the time your order enters the shipping process in our warehouse.
Custom-made items that require production time may be billed well in advance of delivery. Please do not be concerned as this is normal for such items.
Greenhouses.com will not be responsible for delays in processing your order if the credit card billing and shipping information that you provide does not match the information on file with your credit card company. For your own security, most credit card companies maintain an "alternate address file" of authorized shipping addresses for their cardholders. To advise your credit card company of an authorized shipping address, please phone the number on the back of your credit card and they will update your "alternate address file" promptly.
