Q: Can I have a radiant heated wood floor?
A: Yes, installing a wood floor over radiant heat is not much
different from laying a typical wood floor. Most important is good communication
with the radiant heat system designer. For solid wood flooring, strips
3" wide or less are recommended. For engineered products, a lower temperature
is generally allowed in the system than with a solid wood floor.
Q: How about heating ducts?
A: Wood flooring must be protected from excessive heat. Flooring
installed over a heating plant or non-insulated heating ducts may develop
cracks unless protection from the heat is provided. Use a double layer
of 15 lb., or a single layer of 30 lb. asphalt felt/building paper,
or 1/2" standard insulation board between joists under the flooring
in these areas.
