Designer Cumaru Decking

Simply stated, Ipe does not fit into everyone’s budget and we are often asked what is the next best decking choice. In 2005, we began our research to provide a qualified answer to this question. Species included in the research were, Masseranduba, Tigerwood, Cumaru, Cambera, Garapa and Meranti. We looked at dimensional stability, resistance to checking, availability, esthetics and cost. After a thorough study and field testing we determined Cumaru decking to be the next best hardwood choice in outdoor decking. We did observe that over time, Cumaru will exhibit more surface checking and movement than Ipe. However, we expected there to be some slight performance disadvantages. Overall appearance is ranked as high as Ipe and in many cases, they look so similar, some people have a difficult time telling them apart. Its big advantage is cost, typically running about 25% less than Ipe. Offering a tremendous value for projects requiring a smaller budget than Ipe. Our Designer Cumaru decking is kiln dried and milled into our extremely popular micro crown radius edge design. Finally fully sanded for a look and performance no other Cumaru decking can match! For complimentary railing components, fascia or posts, we offer several options in Ipe creating a stunning match.
