The Reasons Why You Need Build A Crawl Space Cover
Before I tell you how to build a crawl space cover, I want to give you some information about crawl space cover.
What is a crawl space cover?
It is the area at the bottom of your house, exactly the area between the floor and the ground of the house.
So why do we need to install and build a crawl space cover?
It has the function of ventilation for your house
What is a ventilation system?
Ventilation is the use of materials such as ducts, fans, ventilation doors, … for the purpose of air conditioning, is the process of exchanging or replacing air for the purpose of providing fresh air. more, and remove harmful air.
Ventilation systems are used to remove unpleasant odors or moisture and hot air, bringing fresher and cooler air inside instead, maintaining air circulation in high-rise buildings. and industrial plants.
Environmental factors that affect humans
The air environment around us has a great and direct influence on us. There are many factors of the atmospheric environment that affect people, below are those factors.
The human body temperature is approximately 37ºC, when the body is active, the body temperature also increases. In order to maintain body temperature, the body must exchange heat regularly with the outside environment, there are two forms of exchange: heat transfer due to difference and sweating, also known as dehumidification.
Relative humidity has a great influence on the body’s heat loss through perspiration. The lower the humidity, the higher the ability to sweat, the more comfortable and comfortable the body feels. On the contrary, the higher the humidity, the less the ability to sweat, the body feels very tired, heavy and easy to cause colds.
In addition, if the wind speed is constant and the humidity is high, the evaporation of sweat will be slow or impossible, which makes the skin surface with a sticky sweat layer that is very uncomfortable.
Air speed has a great influence on the intensity of heat exchange and perspiration of the body. When the temperature and humidity of the air is low, the speed of the air is high, the intensity of heat exchange and perspiration will be high. However, when the temperature of the air is high and the humidity is also high, the high air speed makes us feel hotter, this is why sometimes in the summer using a fan we feel hotter. .
Dust concentration in the air.
This is not only true for areas that need high cleanliness such as schools, hospitals, workshops but even in our homes.
As the standard of living is improved, the level of factories as well as the activity of vehicles and many other ways makes the air more dusty.
Especially small dust particles at 0.5-10µm can penetrate deep into the respiratory tract. The smaller the particles, the easier and deeper the penetration into the human body, the degree of health effects depends on the number and duration of these dust particles.
Concentration of toxic substances.
In the process of production and living in the air, there may be toxic substances such as NH3, Chlorine,… These substances are very harmful to the human body.
Oxygen and CO2 concentrations in the air.
CO2 in the air is not a toxic gas, but when the level of CO2 is high, the amount of O2 will decrease. People without oxygen will feel tired. Excessively high CO2 levels can lead to suffocation, nerve irritation, increased heart rate and other disorders.
Living and working in a high-noise environment for a long time will cause the body to collapse, stress, restlessness and a number of other disorders. The noise level has a great impact on the nervous system and human health. The noise level also affects the quality of work, reducing the ability to concentrate. In some industries to have good quality, the noise level must be less than or equal to the minimum threshold such as: studio, radio and television requires noise level not exceeding 30dB.
Why is it necessary to install a ventilation system?
Causes of reduced air quality:
- Daily life: The use of gas to cook or burn honeycomb charcoal has created harmful gases.
- Increase the activity of vehicles such as motorbikes and cars.
- High population density makes oxygen gas not supplied adequately.
- Fire or forest fire: Occasionally large fires or wildfires also cause air quality to decrease.
- An increase in manufacturing plants that use a lot of fuel, have toxic gas-generating reactions.
- The humid environment creates favorable conditions for molds and viruses to live and grow.
- Wind or storm: wind causes toxic gases to be dispersed far and storms carry large dust particles.
- Volcanoes: in some places with active volcanoes, there will be great pollution due to the dust of lava.
- Waste: if not treated carefully and concentratedly, the waste is also a major source of air pollution.
- Global warming: Hot air will also create conditions for the proliferation of molds and viruses.
Effects of polluted air on human health:
Many people are aware that polluted air will affect their health in the long run. However, what these effects are and which parts of our body are affected are not well known.
- Lung air pollution is definitely affected: Inhaling polluted air makes the lungs work more and the possibility of unfiltered toxins is very large, which will make the lungs hurt and damage broken.
- Cardiovascular: Inhaling polluted air can increase the risk of heart disorders, and can even lead to a heart attack.
- Air pollution may increase the risk of cancer: Inhaling too many toxins can increase the risk of cancer. This is one of the health risks posed by air pollution.
- Air pollution increases diabetes risk: Airborne pollutants can increase the risk of diabetes. According to research, this is because the body is constantly fighting off pollutants and the inflammation they cause.
- The brain is also affected by air pollution: Recent research shows that air pollution can also affect cognitive ability.
- Men’s health is also affected: Reduced sperm quality can affect fertility. This is also considered one of the effects of air pollution.
- Damaged skin: Air pollution can significantly damage your skin. It accelerates the aging process and affects collagen levels in the body.
- And many more: Other health effects from air pollution include eye irritation, cough, respiratory disorders and runny nose.
It has the function of dehumidifying the house

2.Is there an alternative to Crawl Space Cover for ventilation?
Methods of ventilation for houses
In fact, houses of all families often use two common ventilation methods: natural ventilation and forced ventilation.
This is a way to make air flow from the outside into a residential space naturally without using mechanical devices, such as fans.
This is the process of ventilation with heavy mechanical equipment such as fans, air conditioners.. However, this method often comes with high energy costs and is not sustainable.
Several factors help to increase ventilation efficiency
Choosing the right building materials
The first factor to support effective ventilation in the house cannot be ignored.
We should choose materials with voids and voids so that in addition to controlling the sun, they can also allow the wind to circulate easily.
However, what kind of material to use? How much does the gap require us to calculate carefully?
Choose the right type of window
The choice of how to open the door to receive and escape the wind, specifically the type of window, is also something that homeowners need to pay attention to.
With sliding glass windows, when opened, the house will only receive 50% of the wind, but with the door opening on both sides or on one side, up to 100%. This completely depends on the needs and conditions of the family.
Arrange partitions properly
The arrangement of partitions is also one of the notes to ensure effective ventilation for houses. In fact, a high, large, solid baffle will prevent wind from circulating.
So instead of choosing a partition made of concrete, wood panels, a CNC partition, laminated wood, wire mesh … will make the wind circulate much better.
However, it is also necessary to calculate the height of the partition to ensure it is balanced to bring the best ventilation effect.
Reasonable arrangement of entrance and exit doors
When designing a house, homeowners need to pay attention to the arrangement of reasonable entrance and exit doors, helping to circulate good air.
In order to get favorable wind, you should avoid arranging the inlet, and the wind out on the same side, the wind will be round, not circulating.
At the same time, regularly open the door to increase the exchange of air inside and outside the house. For tight townhouses, when the front and rear are close to the house, the owner can open the air outlet in the back, by leaving a small area of about 60cm for the backyard. Above are useful knowledge about effective natural ventilation methods in the house that we want to send to our readers.
Hope you will apply these scientific ways to bring ventilation, comfort and perfection to your home space.
3. The principles of ventilation for houses should know?
Reasonable door layout
Avoid arranging the air inlet and outlet on the same side. The wind will be rough, not able to circulate. With a small townhouse, when the front and rear are close to the house, you can open the air outlet in the back, by leaving a small area (about 60cm) as a backyard.
The layout of the premises should be ventilated for all living spaces by openings, doors and windows as large as possible.
The inlet to the house should be located at the top of the wind and at the bottom of the wall. Meanwhile, the door to let the wind out should be located at the end of the wind direction and at a higher point in the room.
Avoid designing rooms that only open on one side. In particular, the narrow and long form of townhouses depends on cross-room ventilation.
Skylight combined with courtyard
Skylights are a suitable ventilation measure for townhouses. Skylights are not only used as miniatures, bringing green space into the house, natural lighting, but also effective ventilation. The wind will come in from the door and out from the window on the roof of the skylight.
Skylights are placed at the center of the house, increasing convection and pushing hot indoor air from the bottom to the roof.
Pay attention to the exterior and interior
For exterior walls, light textures should be used to increase heat dissipation when the sun is out.
The surface of the wall facing East and West, depending on the case, can be built into a double-layer wall with a space in the middle for ventilation, limiting opening many doors and windows to avoid direct sunlight from the sun.
On the roof: use solar panels or double reflective sheet materials. Green roofs and light colored roofing materials to minimize heat absorption.
Surfaces with textured materials create a shade for the surface, and at the same time increase the surface area that will receive cool air at night many times.
