Types of waterproofing used for homes[modifier le wikicode]
Humidity control can make your home more energy efficient, less expensive to heat and cool, more comfortable, and prevent mold growth.
Properly controlling the humidity in your home will effectively improve your airtightening and insulation efforts, شركة عزل فوم and these efforts in turn will help control humidity. The best strategies for controlling humidity in your home depend on your climate and how your home is built. Proper ventilation should also be part of your efforts to control humidity.
Before you decide on a humidity control strategy, it's helpful to understand that moisture or water vapor moves in and out of the home in several ways, including:
with air movement
By diffusion through the material
by heat transfer
creating humidity inside the house (cooking, bathing, etc.),
Of these, air movement accounts for more than 98% of water vapor movement in building cavities. Air naturally moves from areas of high pressure to areas of low pressure by the easiest path available - generally through any available opening or crack in the building envelope. Moisture transfer by air currents occurs rapidly, and carefully and permanently closing off any unintended pathways of air movement in and out of the home is a very effective method of humidity control.
The other two driving forces - diffusion through materials and heat transfer - are much slower processes. Most common building materials greatly slow the spread of moisture, although they do not stop it completely. Insulation also helps reduce heat transfer or flow.
The laws of physics control how moist air reacts under different temperature conditions. The concentration of temperature and humidity at which water vapor begins to condense is called the "dew point". Relative humidity (RH) refers to the amount of moisture present in an amount of air compared to the maximum amount of moisture that the air can hold at the same temperature. The ability of air to hold water vapor increases as its temperature increases and decreases as it cools. Once the air reaches its dew point, moisture that the air cannot hold condenses on the first cold surface it encounters. If this surface is within the cavity of the outer wall, the result is damp insulation and framing.
In addition to air movement, you can also control the temperature and moisture content. Insulation reduces heat transfer or flow, so it also mitigates the effect of temperature across the building envelope cavity. In most US climates, properly installed vapor diffusion inhibitors can be used to reduce the amount of moisture transfer. With the exception of intentionally ventilated spaces such as attics, insulation and vapor diffusion inhibitors work together to reduce the chance of condensation in a home's ceilings, walls, and floors.
Moisture can cause problems in attics, different types of foundations, and walls, and solutions to these problems vary depending on the climate. See Building Climate Publications for America for building details specific to your climate.
Base moisture control
The potential for moisture problems exists anywhere a building's components are below grade, whether you have a basement, crawl space, or slab foundation. To create a comfortable and energy-efficient living space in the basement, you will need to properly insulate and control moisture.
Most basement waterproofing results from water flowing through holes, cracks, and other interruptions in a home's basement walls or wicking water into the cracks and pores of porous building materials, such as masonry blocks, concrete, or wood. These tiny crevices and pores can absorb water in any direction - even upwards.
The best approach to preventing these problems will depend on your local climate, type of insulation عزل الخزانات , and construction style. If you need to correct moisture issues in your existing home, consult a qualified builder, basement designer, and/or insulation contractor in your area for specific basement moisture control measures tailored to your climate, insulation type, and building style.
If you are building a new home, pay special attention to how water is managed around the foundation. The following guidelines will apply in most cases:
Keep all untreated wood materials out of contact with the ground.
Install well-designed gutters and a drainpipe connected to a drain system that diverts rainwater completely away from the house.
Slope the floor off all sides of the house at least 5 feet at a pitch of at least 5% (3 inches by 5 feet). Create drainage swamps to direct rainwater around and away from the house.
Add a gasket under the sill plate to provide an airtight seal.
Install a protective membrane, such as rubber roofing or ice dam protection material, between the foundation and sill plate to act as a capillary spacer and reduce water wicking from the masonry foundation wall. This membrane can also act as a shield from termites on top of the foam board insulation.
Moisture Resistant All lower grade parts of foundation and footing wall to prevent the wall from absorbing ground moisture by capillary action.
Place a continuous drain level over the damper or external insulation to direct water into the foundation drain and relieve hydrostatic pressure. Drainage surface materials include special drainage mats, high-density fiberglass insulation products, and washed gravel. All sewer seams must be protected with filter fabric to prevent dirt from clogging intended gaps in the drainage material عزل الشينكو .
Install the foundation drain directly below the drain level and next to (not above) the base. This prevents water from flowing over the seam between the base and the foundation wall. Surround a 4-inch perforated plastic drain tube with gravel and wrap it with a filter cloth.
Install a capillary separator and a vapor diffusion inhibitor under the sub-floor or on the floor of the row, consisting of a layer of 6-10 ml of polyethylene over the https://www.tsaropat.com/
