- The relative humidity for an indoor environment should remain at most 60 percent; however, 50 or lower is ideal, according to HVAClean. Humidity levels higher than 60 cause mold to grow inside air ducts.Mold growth potentially leads to respiratory problems and allergies. Running a thermostat constantly in the On position is hard on cooling units. Freon gas cools the evaporator, but with a consistent flow of air the coils are unable to stay cool.umidity levels higher than 60 cause mold to grow inside air ducts.

What Is the Ideal Home Humidity Level? Ideal Home Humidity Level. That being said, maintaining an ideal level of humidity indoors is essential. Average humidity levels should range between 30-50% percent; however, experts suggest that the most favorable in-home humidity level should be close to 45% for optimal health and safety. Humidity levels can be easily gauged with a hygrometer. This device is employed to calculate relative humidity in the surroundings and monitors the humidity levels at home. Put three ice cubes in a glass of water and stir it a few times, waiting for about three minutes.

- To maintain the correct humidity level in a basement, place a dehumidifier in the basement, and connect it to the existing main stack, feeder drain or utility sink. If the dehumidifier doesn't measure the level of humidity automatically, place a hygrometer next to it. You can also turn on the exhaust fan when somebody is showering or venting the clothes. The ideal moisture level for a basement ranges from 30 to 50 percent relative humidity.

Moisture and Humidity Measurement Still Crucial for Engineered Flooring Relative Humidity Concerns. The space for the engineered flooring needs to be conditioned based on the manufacturer’s guidelines. Manufacturers typically require a range between 35% and 55% ambient RH, but those guidelines can vary. Some manufacturers may have a range of 40-60% RH while others may require 30-50% RH.

Recording Moisture Levels Before Fitting Wood Flooring If your subfloor is concrete and recently laid, you’re likely to face more of a challenge when it comes to moisture. Ideally you should aim to have a reading of somewhere between 35 and 40% humidity or 2-3% moisture content before laying your new floor. With concrete slabs taking an estimated month per inch to dry out, this can become quite a challenge.

How to make sure that your flooring is properly acclimated. A good representative sample is typically 40 boards for every 1,000 square feet of flooring. Calculate what the optimal wood moisture content is (baseline) by dividing the high season and low season. Example: If your region has an expected EMC from a low of 6% to a high of 9%, the baseline MC of the wood would be 7.5%. If wood flooring is delivered and recorded to its baseline MC for the geographical location and proper relative humidity conditions are maintained, no acclimation may be required.

What Problems Does Moisture Create? These principles mean that if the relative humidity in the concrete slab is different than the relative humidity of the air above the slab, then moisture is going to try to move in or out of the slab. Without a vapor barrier, the relative humidity in the slab just below the surface can often be 100%. Since the air is seldom that humid, moisture is going to move from the slab into the air and as the surface dries a bit it will draw moisture up from the bottom.

How do you know when a chemical reaction has occured? Exothermic and endothermic reactions. When a chemical reaction occurs, energy is transferred to, or from, the surroundings-and there is often a temperature change. For example, when a bonfire burns it transfers heat energy to the surroundings.ndothermic reactions. These are reactions that take in energy from the surroundings. The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to get colder.

Concrete Vapor Barriers â Understanding Concrete Moisture Problems The concrete slab is then poured directly over the vapor barrier. (This was not always the case. Prior to the 2000s, a “blotter” layer was recommended between the vapor barrier and the slab. But this practice changed as the difficulties of keeping the blotter layer moisture-free became evident.).here still may be situations where a vapor barrier is necessary over a concrete slab. Even when a slab is dry enough for the recommended use, it is still possible for moisture to migrate from the slab into porous or absorbent flooring materials like wood.
