Find answers to the most frequently asked questions.

What kind of underlayment do I need?

Usually the existing underlayment or subfloor is sufficient, and no other underlayment is needed. On all nail-down installations a paper is used, similar to tar paper, for an underlayment.

If I need a moisture barrier, is there a brand you would recommend?

We recommend Bostik® MVP (Moisture Vapor Protection)*

What about installing wood in high traffic areas like kitchens?

We at 7th Heaven Floors recommend a Urethane finish which  is able to resist water and traffic, bringing wood flooring into restrooms, kitchens, and other higher-stress areas. High-traffic areas include exterior doorways, hallways and in front of the sink, stove and refrigerator. To protect the floor on the inside of exterior doorways, use floor mats to catch tracked-in dirt and grime. Watch for grit or pebbles that might be brought in from shoe soles. Vacuum on a regular basis.

Which types of hardwood floors are best for in-floor radiant heating systems?

Radiant heating is a growing source of heating in North America, both in residential and commercial installations. Engineered hardwood floors are the best floors to use with radiant heating systems. These floors are manufactured of hardwood using a three-ply laminated construction, making them dimensionally stable and less susceptible to changes in temperature and humidity. Of the engineered flooring options, a floating installation may be considered the best choice, because it can be ‘floated’ over the subfloor, without the use of nails or adhesives for a permanent installation.

It is important to note that when installing any hardwood floor over a radiant healing system, the maximum temperature of the subfloor should never exceed 85° F (below 80° F is recommended). The heating system MUST be turned off 24 hours prior to installation and must remain off for 24 hours after installation.
