The main ingredients of isogam types
Bitumen (bitumen is a waterproofing bitumen which, with its special characteristics, gives Izogam the ability to stick and be insulated).
Fireproof glass wool or tissue (it is a synthetic fiber tissue that is 99% resistant to direct fire and various weather conditions).
A polymer material called tactic polypropylene
Needle polyester
Polyethylene film
Aluminum foil: (This material defends isogam against various atmospheric factors and has an important effect on the durability of isogam).
How to detect a quality isogam?
There are many ways to distinguish a quality isogamy from a low-quality isogamy. Some of the simplest ways are:
The smell of isogam
The simplest and most basic method to distinguish good isogam from bad is through the sense of smell. In general, Izogam does not have a very pleasant smell, and this is the characteristic of all petroleum products, however, the strong smell of diesel indicates the poor quality of Izogam.
Isogam
To recognize the quality of isogam, it is enough to run your hand on the part of the outer layer of isogam that is not covered. If the isogam material is good, nothing will stick to your hand, but if it is of poor quality, small black particles will stick to your hand.
Keep in the freezer
Another very simple method regarding the quality of isogam is to use freezing. For this, cut a small piece of isogham and put it in the freezer. Then after 2 hours, take it out and bend it with your hand. If the isogam broke or even cracked because you bent it, the material of the isogam is not good, but if it remains intact, it means that it is a good isogam and is resistant to cold and heat.
ویژگی هایی که در هنگام خرید ایزوگام باید نسبت به آنها توجه داشت:
Proper raw materials
Isogam made of bitumen with a concentration of 60 to 70% is excellent and certainly has high quality. The use of first-class tissue also has a double effect on the desired quality of isogam. Of course, note that the use of good material increases the price of isogam as well.
Omar isogam
Generally, a good isogam lasts between 10 and 15 years, but the issue of isogam's longevity is not so simple and depends on many factors. Factors such as weather conditions, sunlight and its storage conditions are among the other things that affect the lifetime of isogam.
The thickness of the isogam
National Thickness Standard Organization has declared 0.2 ± 4 mm as a suitable average for detecting the quality of isogam. This means that the acceptable average thickness is 4 mm and it is acceptable from 3.8 mm to 4.2 mm. Of course, this number varies depending on the number of isogham layers (single layer, two layers or three layers).
Weight isogam
In general, a standard insulation has a weight of 4 kg per square meter. Therefore, a standard roll of isogham, which is one meter wide and ten meters long, should weigh 40 kg.
The length and width of the standard isogam roll
Usually, the width of a standard isogam is 1 meter and its length is 10 meters. Rolls with less or more length and width are not considered standard.
How to distinguish a original isogam from counterfeit isogam?
Unfortunately, the market is full of fake and low-quality isogams. However, don't worry too much, because the original Isogam has features that distinguish it from the fake Isogam:
The original Izogam must have a registration number.
Isogami, which is original, is transparent and does not have an unpleasant smell.
An isogami that is original has a standard sign.
Isogami, which is of poor quality, is dry and brittle at 10 degrees.
What is the best season for isogam?
The best and most suitable season for isogam work is summer. The reason for this is that if you do your isogam operation in the summer, you can be sure that your isogam will prevent the effects of the cold season, will be more durable and will have a longer life.
Be careful that in addition to the good and high-quality material of Isogam, the cleanliness and dryness of the surface on which Isogam is going to be done is very effective in the durability of Isogam, and if the work surface is warm and clean, it will make Isogam stick better. For this reason, it is recommended to do the insulation work of your building in the summer season.
