All about the best double glazed doors and windows and UPVC profile

The sound of breaking window glass has been a part of people’s lives in the past. Sometimes it was because of playful kids throwing stones, or sometimes because the ball hit the glass while playing. But the breaks and the noises were not the whole story. The main problem is found in summer and winter. When the heater was on fire until the end, but half the heat of the house was lost.

As time went on, the glass changed like all the old things. They progressed and updated. Until the double glazed window finally entered the market. This window with its optimal advantages created a great change in the construction industry. These days, the market is full of models, quality and price of double glazed windows. In this abundance, buying a double glazed window for the building is not a problem at all. The main issue is choosing the best double glazed window for our house.

We are with you in choosing the best double glazed window. In today’s article, we are going to review the types and varieties of double glazed windows in the market and guide you in choosing the best type. So do not miss this article in any way.

Why double glazed doors and windows?

There are many types of doors and windows today that any person can use one of them according to their tastes and needs. To see the types of windows, refer to the article introducing the types of windows, from wooden profiles to advanced upvc. But double-glazed windows can be distinguished from other doors and windows by three general factors. We examine these three factors together.

1.      The double glazed window is very good sound insulation

Imagine that there are 8 million people living in Tehran. This means that there is a population as small as a country in this city. The city is really crowded and in today’s life, you have to struggle with various things outside the house that may get on your nerves. Work problems, accidents, social conflicts and much more.

When you get home, all you need to think about is a cozy, relaxing corner. Silence is all you need. But the hustle and bustle of the city will not leave you even at home! In such cases, double-glazed doors and windows will help you and will save you and prevent additional noise from penetrating into your living environment.

2.      Double glazed windows are very good thermal insulation

How much does it cost to heat or cool your home? If you think these costs are high and you spend a lot of money every month on home energy, the problem may be solved by installing double glazed doors and windows. These windows, due to the profiles in which they are used and their reliable insulation and formwork, prevent the loss of a large amount of energy and play an important role in reducing costs.


3.      Double glazed doors and windows are very good dust insulation

For most of us, cleaning and dusting our homes is part of our Friday routine. It never works, and until next week new dust will settle in the house. But the good news is that a double glazed window can go a long way in helping you clean your home! Because of their structure, these windows prevent dust from entering your home. And dramatically increases the distance between household cleanings.

 What should be considered in choosing a suitable double-glazed window?

I hope that with the explanations that I presented in the previous section, you have come to the conclusion that the best type of doors and windows for your homes are double-glazed doors and windows. It’s time to review the important points that you should pay attention to when choosing and buying a suitable double-glazed window.


What is the significance of the profile in a double glazed window?

The profile used in the construction of double glazed windows is one of the most important factors to consider. Usually, we need profiles with different characteristics and features in different applications. But in Iran, such points are not taken into account and the choice is made only on the basis of price.

 Polyvinyl Chloride (PVC)

All about Polyvinyl Chloride (PVC)

Polyvinyl chloride, or PVC for short, is one of the most common thermoplastic polymers. Inherently, PVC is white and has a very dry and brittle nature. In terms of antiquity, PVC has a longer history than most other polymers. The polymer first appeared in 1872 and was commercially produced in 1920 by the renowned company B.F. Goodrich. In general, the introduction of most other common polymers dates back to the 1940s and 1950s. The manufacturing industry is considered to be the main hotbed of PVC, but it is also used in the production of medical supplies and fibers used in clothing.


Polyvinyl chloride is produced in two general forms: dry and brittle (RPVC or UPVC) or flexible plastic. Soft and flexible PVC, or regular PVC, actually react better to bending due to the addition of plasticizers such as phthalates (typically DINP). This type of PVC is mainly used in the construction industry to insulate electrical wires or to produce flooring for homes, schools, hospitals and all places where having a sterile environment is a top priority. Also, in some cases, this type of PVC is used as a substitute for rubber. Dry PVC is mostly used in the production of water and sewage pipes.

All about Polyvinyl Chloride (PVC)

Some of the most prominent characteristics of PVC are relatively low price, high resistance to environmental factors, chemicals and bases, high hardness and excellent tensile strength.

What is the reason for the popularity of polyvinyl chloride?

Dry PVC, as
a plastic, has a very high density, which makes it a hard and strong plastic.
Also, due to its high availability, cheapness and long life, PVC is an ideal
option for common construction applications.

PVC and 3D printing

In the article related to 3D printing, it was mentioned that one of the major
disadvantages of 3D printing is the lack of support for the full range of
polymeric materials. Although this spectrum is constantly expanding, ABS and
PLA (polylactic acid) are still the predominant plastics in 3D printing.

The biggest challenge facing the use of PVC in 3D printing stems from its erosive nature, which severely overshadows the longevity of the printer’s internal components. So far, some efforts have been made to make nozzles suitable for PVC, but none of them have been fruitful.

PVC and CNC machining

PVC can be cut into CNC machines. However, naturally all the experts of these machines have noticed the effect of PVC erosion on the blade of the car. In fact, if the blade is not made of stainless steel or corrosion-resistant metal, it will corrode a lot over time due to the corrosive nature of PVC.

PVC and plastic injection machine


This polymer, like other polymers, can be used in the injection molding process. However, the presence of chlorine in the structure of the material complicates the process. This is because molten PVC emits a toxic, corrosive gas. Naturally, the host workshops of these machines must be equipped with a proper ventilation system. It is also necessary to use corrosion-resistant materials such as stainless steel or chrome-plated materials in the mold structure. The shrinkage and shrinkage of PVC in the injection process will be equal to 1 to 2 percent, and of course will vary depending on the material hardness, gate dimensions, melting temperature, mold thickness, mold temperature and the percentage and type of additives.

Is PVC toxic?


Because PVC releases hydrogen chloride vapor during combustion, it can be considered a serious health threat. Electrical wires with non-PVC insulation are commonly used in applications where the risk of fire is high. These vapors are also released during the melting of the material, and as a result, the process of production and use of PVC must be supervised and performed with complete care.


Advantages of PVC

Compared to other polymers, it has a very high density (relative density of about 1/4) and is therefore very hard and resistant to deformation. It is readily available and therefore relatively inexpensive. Dry PVC has a very high tensile strength. It has very good resistance to chemicals and bases.


Disadvantages of PVC

It has very poor thermal stability. Therefore, stabilizing additives are usually used in the production process at high temperatures. It releases toxic fumes when burned or melted.


Technical characteristics of PVC


The properties of PVC are as follows:

Technical name: polyvinyl chloride

Chemical formula: C2H3CI) n)

Thermal bending temperature: 92 ° C

Melting point: 100-260 ° C

Tensile strength:


  • Soft PVC: 6/9 to 25 MPA
  • Hard PVC: 34 to 62 MPA

Relative density: 1/35 – 1/45

The last word

Despite the shortcomings mentioned, polyvinyl chloride is considered to be an extremely useful polymer overall. Its unique properties have made PVC an almost invaluable option in construction projects.
