Ideal Moisture Sub Floor House

The ideal humidity for the home is around 40 to 50 percent which is high enough to prevent things from drying out but low enough to prevent damage and mold growth.

Ideal moisture sub floor house.

2 4 acceptable variance between top layer subfloor. This chart highlights the ideal levels of moisture in wood at various temperatures and relative humidity rh levels. When that occurs dirt and dust or other debris under the subfloor could become a substrate for mould growth. For all intents and purposes the ideal moisture of flooring wood will be the moisture content at which the wood reaches equilibrium with the installation environment.

Today it was at 12 or 14 still. 2 4 represents the acceptable level of variance between the top level of your wood floors and the subfloors. While it s important to extract moisture and treat the top level of your wood floors it s all for naught if you don t do the same for the sub floor. A week ago it was down to 12 or 14 depending where you checked.

Or the subfloor may be made of plywood or other panel products that are laid perpendicular to the joists. The efflorescence you are seeing when you lift the individual subfloor tiles is caused by minerals leaching from the concrete. This occurs from water that either leaks under the subfloor or from moisture within the concrete slab itself. At this equilibrium moisture content emc wood will stop absorbing or shedding moisture which prevents some of the physical problems that can occur in wood flooring.

It may be made of boards laid either at right angles or diagonally across joists. 2 for plank 3 wide or more hardwood and 4 for strip 2 wide hardwood. Subflooring provides a base for finish flooring and also serves as a platform during construction. With the addition of decks and increased vegetation from gardens and shrubs the natural cross flow ventilation under homes can be negatively impacted and the usual humidity released from the ground therefore cannot escape the sub floor space.

Tile and stone flooring can be installed directly over concrete but most other flooring materials require some kind of underlayment and or a moisture barrier laid over the concrete. Moisture is constantly released into the atmosphere from the earth and is dispersed by the wind. This will vary from product to product. Two weeks ago the moisture in the subfloor was 22.

I m using a pin tester and checking at a depth of 1 8 to 1 4. These are the safest conditions for most types of wood between 60 and 80 degrees fahrenheit and 30 to 50 rh. A concrete slab makes for a very hard solid durable and often very smooth subfloor. High humidity in the home can cause serious problems with your flooring.

Humidity is the amount of water vapor in the air.
