Why’s our siding and decking woods superior to your other suppliers?  Because it is Kiln Dried!! Not air dried like most Ipe sold as decking or just plain green like some of the Cedar Decking. Ours is Kiln dried. All our species are. And if we do get some material in that is wetter than our specs we have the kilns to dry it in.Don’t be fooled by your supplier claiming their Ipe is͞ well air dried or that a green Cedar board will work for any application. It won’t and you will be left with shrinkage, cupping and checking.

There is no standard for air dried material its buyer beware. We used to buy air dried Ipe with assurances from the supplier that would be 17% or something like that or less. Never was! Lots of times the outside boards were near the claimed moisture but the insides of the bunks would be as high as 50%! Lots of shrinkage in a board that wet. We have measured lots of Ipe and other species to determine how dry they should be for siding and decking.

Keep in mind that on a wall in the Midwest a board is going to end up at around 5 to 7% moisture on the sunny side of the building and 7 to 12% moisture on the shady side. An air dried Ipe board that has gone from 40% to 7% will shrink about 3/16 of an inch on average. Some more some less. So if you are going to go to that much trouble to build an Ipe or Cedar deck or wrap your structure in beautiful wood make sure the wood is Kiln Dried so it will move little and check less…

Wood Haven is one of the few supplies of exterior and interior millwork with their own kilns. We guarantee the material will be at a moisture level that is suitable for your environment.
