Why are your custom built doors an important part of your greenhouses?
We manufacture our custom designed Western Red Cedar doors.. They are composed of the same Select cedar that we choose for our greenhouses.
Many of our competitors buy lumber yard "premade" Fir doors. Unlike Fir, Cedar does not decay or warp in the humid environment of greenhouses. As well, our doors are a perfect match to our greenhouse designs. Doors are a very important part of your greenhouse.
What is the advantage of a Dutch Door?
Dutch Doors are doors which are split, allowing you to leave the top half open and the bottom half closed. This keeps unwanted guests out of your greenhouse while allowing for optimum ventilation. Ventilation is a very important factor in your greenhouse for healthy plant growth. See our Dutch Door page

FREQUENTLY ASKED QUESTIONS
What if I receive a damaged or missing piece?
Cedar-Built Greenhouses guarantees that if you have any problems with broken or missing pieces we will ship out a replacement part. We have all parts in stock because we are the manufacturer. Our sturdy plywood crating ensures a 99% damage free shipments.
What are the advantages of Twin Walled Polycarbonate over standard glass or single layered glazings?
Twin walled polycarbonate is the standard glazing supplied with our kits.. Guaranteed unbreakable, highly insulative, UV resistant, lightweight, and 300 x stronger than glass. Channels between the double walls trap air to reduce the risk of leaf burn, and eliminate condensation build-up, (dripping from overhead). Our twin wall polycarbonate is precision precut to our specs by our supplier.
If you prefer clear, see-through sidewalls we offer UV resistant, unbreakable, rigid 3mm clear plexiglass. Plexi-glass is used in many outdoor applications (including airplane windshields and baseball stadiums!)
Clear 3mm plexi-glass has a life time warranty against any yellowing, breakage or any of mother nature's elements. This glazing is very popular for those who prefer clear viewing both in and out of their greenhouse walls.
Mix and match! We can mix the panels as per your request. Some folks prefer plexiglass on one or more walls facing their home or view. Tell us what you want. We can work with you.
What is an R-Value?
An R-Value means the insulation value and are used to measure insulations ability to resist heat flow. The higher the R value, the more effective it is.
How do I heat the greenhouse?
Mr. McClure ( 8x10 ), " It really has been fun this winter, the temp was down around Zero last night and the inside of the greenhouse was around 55 degrees with just a 110 volt electric heater set on medium."
Mr.Saltzman ( 8x12 ),"I have put in an electric heater at the far end from the door and it maintains air temperature well. This morning was 15 F and I went out to the greenhouse to water, it was a cozy 73. I got my first electric bill since turning on the heat and did not notice anything dramatically different."
Mrs. Thiffault ( 8x12) "We are in the mist of winter and from our kitchen window and dining room windows our greenhouse is fighting the elements of whatever comes our way. Surprisingly with a few days of minus 13 night our roses and geraniums
have survived with no heat .( Andy insulated the base walls this fall). By the way our cat Oland loves to visit and sleep in the greenhouse."
Mr. Silva (10x18) "It is amazing how well the greenhouse holds the heat. The little electric heater runs very little after it gets the greenhouse warmed up. It has been freezing every night but with the little heater it stays nice and warm."
These clients ordered the twin walled polycarbonate upgrade and insulated the cedar basewalls.
On cooler winter days the sun will warm your greenhouse significantly. Cedar maintains the temp for long periods of ime. Many of our clients use small electric heater which they find adequate to ward of the chill in the evenings.. If you plan to run gas lines and a small furnace to your greenhouse, we suggest that you contact your local heating contractor. He is the expert who will both install and warranty your furnace/heater for you. Cedar is the warmest most insulative wood in existence.
