What cold insulationnada shaban
Cold insulation is what prevents the transfer of heat from the surrounding air to the object to be insulated.
The answer to the question: What is cold insulation? Thermal insulation prevents the transfer of heat from the surrounding air to the object to be insulated, or transfers the least possible amount of heat to the insulated object, so that it does not lead to raising the temperature of the content of what has been insulated.
Cold insulation is usually able to prevent condensation but leads to moisture leakage. When hot air meets a cold surface, the air is unable to absorb moisture, so it causes moisture to build up.
Condensation is like condensation on the mirror in the bathroom after showering. It is in the same shape in the insulating materials, and this leads to a weakening of the insulator’s ability to insulate, and the surface beneath the insulator exposes itself to corrosion.
The insulating material must be protected from spreading or being penetrated by any moisture or water condensation. We can use bitumen as a vapor barrier. This insulator is installed on the outer surface and this prevents the absorption of water vapor into the insulation, which preserves the insulation and its validity.
We can also define cold insulation as a means of slowing down the transfer of temperature from one body to another. Cold insulation is used on the roofs of buildings and in water pipes to prevent water leakage or the transfer of heat to them. It is also used to insulate the roofs of buildings because it reduces the feeling of heat inside that house, unlike If you are not insulated, you will feel the heat directly above it.
Uses of cold insulation
- Cold insulation is used to insulate the infrastructure of buildings before they are established so that water does not seep into it from under the ground.
- Insulation is also used in the foundations of buildings to provide rigidity and insulation from any leaks.
- Waterproofing is used in swimming pools, toilets, and water tanks. Insulation is used so that no water leakage occurs.
- Cold insulation is a vapor-protective layer that does not allow steam or condensation to penetrate into the wall or floor.
- It is also used in streets before paving the ground with ceramics.
- It is also used on the roofs of buildings to reduce temperatures and their penetration into the last floor of the building.
What cold insulation
Is bitumen waterproof?
Yes, bitumen is waterproof and highly resistant.
Bitumen, known as asphalt, is a liquid material and highly viscous due to its water-resistant properties. Therefore, it is widely used in construction and is considered ideal for insulating roofs, bridges, etc.
Bitumen is waterproof to a very great degree, so it is used in inclined insulation of water tanks and swimming pools. It is also widely used in insulating toilets and the infrastructure of the building foundation because it does not permeate water, which is what we need.
The best types of insulation
- Fiber glass.
If you do not know how important insulation is, I will tell you that it will guarantee a fairly constant temperature in your home, which will save you expensive bills for the heater and air conditioner that you consume. While each type of insulation has advantages and disadvantages and is used in specific places, we may prefer foam, for example. In children’s rooms, we do not prefer it in some other rooms.
If we compare the types, we will see that the type that achieves comfort in the home is foam, but the cheapest is fiberglass. This difference in price comes because fiberglass and cellulose need to be changed constantly and over time, while foam can be used once and it will remain with you and you will not need to change it or change it. Renew it from time to time.
Safety factors are available in all three types, as the three materials – cellulose, fiberglass, and foam – contain materials classified as first class against fires. They will not prevent fires in your home, but they will certainly not help them ignite.
If you want to insulate the roof of your home, we will show you the advantages and disadvantages of the three types and choose what suits you:
Foam: It is an insulating and air-blocking material that prevents air from penetrating inside. It can expand 100 times more than its original size and fills every corner of the roof of your building. It is made from organic chemical compounds derived from petroleum extracts. It is primarily fire-resistant and does not retain water inside. This protects the walls and ceiling from the growth of fungi and mold, but it is somewhat expensive and requires a professional to apply it.
Fiberglass: An insulating material, of course. It consists of very fine pieces of glass fibres. It is inexpensive, but it also does not form an impermeable barrier against the air.
Cellulose: It is the oldest insulation material, and it is fairly inexpensive. Cellulose can stabilize only about 20%, but it cannot form an air barrier, so cold and hot air move back and forth.
What is cold bitumen?
It is a mixture of mineral aggregate and other materials and mixed bitumen is used to repair road cracks.
It is known as cold bitumen because it does not need to be heated to apply it and spread it on the asphalt or road. Rather, it is used while it is cold, so it is used directly on roads, repairs, and insulation without the need to heat it first.
One of the benefits of cold bitumen is that it is inexpensive because it does not require heating and preparation equipment. We can buy, store, take and use it whenever we want to repair roads, and it is very effective in repairing cracks.
It is also a very suitable solution for all weather conditions. Unlike hot bitumen, which cannot be used in the winter because it is hot and the ground is cold, when it is poured over it, the material does not flow due to the cold ground.
