Eastern Red Cedar

Eastern Red Cedar

Eastern Red Cedar

I have a client that wants to use Eastern Red Cedar for exposed rafters. The 2015 NDS does not specify design values for Eastern Red Cedar. Does anyone no where I can obtain these design values? The NDS does specify Western Red Cedar.

RE: Eastern Red Cedar

I would check with lumber supplier first. I doubt you will find any Eastern Red Cedar large enough for rafters.

RE: Eastern Red Cedar

The members will be used as exposed outriggers around a builder, thus the spans are really short. Again, does anyone know where I can find design values?

RE: Eastern Red Cedar

You could try Northeastern Lumber Manufacturers Association: NELMA

RE: Eastern Red Cedar

try the Book "Wood in Australia"

RE: Eastern Red Cedar

Different species. Eastern Red Cedar is a Juniper. Alaskan Cedar is a Cypress.

RE: Eastern Red Cedar

As Hokie says, Eastern Red Cedar is a juniper. It's stronger than Western red or Eastern white, but you're never going to find any large enough for rafters. The trees themselves rarely exceed 8" dia. or 25' high, they branch like crazy, and the wood is only commercially marketed for aromatic purposes (anti-insect) for closet linings and the like.

RE: Eastern Red Cedar

My best friend lined a very big closet with what I think was Eastern Red Cedar.
He got nasty headaches from cutting it.
Upon inquiry, his supplier said it was toxic, and he should have been wearing a respirator.
I'm guessing that's why the bugs avoid it.

Exposed rafters do not sound like a good application for it.

I do love the spectacular coloration and grain.
Maybe you could make the actual rafters from a less aromatic wood,
and apply the ERC as a veneer, sealed with a heavy coat of something clear
on all faces and edges.

The rustic souvenir industry produces a lot of trinkets from ERC
or similar, with a glossy thick finish like decoupage.
