Quartersawn Sapele With Radiant Heat

mike-wbFebruary 12, 2011

We have just broken ground on a large renovation/addition to our house in NJ. We intend to use Radiant Heat (HYDRO) throughout the main and upper levels and baseboard heat for the lower level which is on a slab.

We initially looked at engineered hardwood flooring and fell in love with the Sapele from Mirage which is rated for use with Radiant Heat. After a great deal of back and fourth, the Architect and General Contractor are trying to steer us toward a Quarterawn 3/4" plank vs. engineered. While my research has indicated that quartersawn planks (usually Red or White Oak) are appropriate for this application, my question is "Is Quartersawn SAPELE Appropriate for this application?"

My understanding is that Sapele is a reasonably stable species, but was told that with exotics humidity and dryness are also a major concern. This makes sense but if the Sapele flooring is delivered from the mill at the correct moisture level and is properly acclimated, will it work or will I be sorry?

Chapter 3 of the Wood Engieering Handbook covers how wood changes shape and size with moisture content.

While quartersawn wood has some desirable properties. it still changes size with moisture content.

Data for Sapele is in the tables.

Figure 3-3 shows how the shape of wood changes depending on its location in the tree and its orientation to the growth rings of the tree.

Here is a link that might be useful: Chapter3, Wood Engineering Handboook

I am thinking of using Sapele over radiant flooring too. Any further advice?
