What is environmentally friendly double-glazed windows. Eco-friendly double-glazed windows - wood or pvc? Examples of our work

Window structures produced on the latest equipment from environmentally friendly materials that do not emit substances harmful to human health and the environment are called eco-windows. Strict quality control of products is carried out at all production stages.

Work examples

Which windows are considered the most environmentally friendly and safe?

Today there are three main types of safe window products based on profiles:

Plastic

Manufactured from PVC free of lead stabilizers. Recommended for use even in children's and medical institutions, Easy to clean, airtight, durable, reliable, resistant to the negative effects of weather, have a high rate of heat and noise insulation, have a wide price range, a large number of options for shapes and colors.

Wooden

Made from pine, oak or larch wood. For resistance to fire, insects, mold and fungus, wood is treated with special compounds. They are characterized by excellent indicators of heat saving and sound insulation, high maintainability, resistance to low temperatures, aesthetics. Thanks to the microcirculation of air through the pores in the wood, they create a special microclimate in the room. The main disadvantage is the high cost.

Glass composite

Made from fiberglass. They have high strength, thermal insulation, maintainability, have a wide color palette. Resistant to deformation, temperature fluctuations, corrosion, moisture, fire and ultraviolet. Do not emit harmful substances. On average, they are 20% more expensive than plastic products.

1.

Eco-friendly PVC windows of the KBE brand, produced using the Greenline lead-free technology, became one of the first in this direction. The chemical compound calcium-zinc acts as a stabilizer.

The German company Rehau has also made a choice in favor of environmental friendliness and began to produce plastic profiles without the use of harmful substances. This is confirmed by a hygienic certificate of conformity. Structures can be recycled, saving resources and respecting nature.

Key Features:

• the absence of excretions harmful to the body, due to the use of safe chemical compounds in the production;
• a large selection of shapes and colors;
• high noise and heat insulation performance, tightness;
• great price variety;
• durability, up to 40-50 years of operation;
• ease of care;
• reliability, resistance to negative external influences.

Myths and truth about plastic eco-windows

The main myths that scare buyers who choose this option:

MYTH #1: Polyvinyl chloride (PVC, plastic), from which the profile is made, is a harmful substance.
TRUTH: In its pure form, it is a white powder, mixed with other, safe components during production. As a result, it becomes inactive and does not emit substances that pose a threat to human health and the environment.

MYTH #2: For stabilization, lead is used, which is a dangerous poison. Over time, under the influence of high temperatures, when exposed to direct sunlight, lead begins to stand out, poisoning everything around.
TRUTH: Manufacturers of eco-windows have long refused to use lead compounds in production - they were replaced by absolutely harmless compounds of calcium and zinc.

MYTH #3: Tightness not only completely removes drafts, but also makes it impossible for microcirculation of air in the room. As a result, it stagnates, is not saturated with oxygen, and an unpleasant odor occurs.
TRUTH: Modern plastic windows are equipped with a micro-ventilation mode, as well as ventilation air valves, which ensures the supply of fresh air in sufficient quantities.

2. Wooden windows

The materials from which environmentally friendly wooden windows are made are of natural origin, and not obtained as a result of chemical reactions. Naturalness is the main advantage of these designs.

Characterized by a high degree of flammability and exposure to bark beetles, they need special impregnation, and for resistance to the influence of negative natural phenomena - painting. Modern manufacturers offer paints and impregnations that are safe for health, do not emit substances harmful to the body and the environment during use, and perfectly cope with the task.

3. Eco windows made of fiberglass

Glass composite as a material for the manufacture of window profiles was patented by Canadians. It is produced by pultrusion, the process consists of two stages:

• Fiberglass is pulled through a container filled with thermosetting resin (predominantly polyester).
• The resin-coated material enters a die heated to 150 ° C. Here it solidifies and takes the form of a die.

Comparison of profile characteristics

Most windows (more than 60% of the total) are made of plastic today. The leadership of PVC in window technologies and the sympathy for it on the part of end users is not accidental: they love it for their high energy-saving and noise-proof properties, wide design opportunities, for their reliability and safety. If something else raises questions and generates discussions, it is the range of topics related to ecology and environmental protection. How environmentally friendly are plastic windows? How safe is their production, what happens to such windows after their service life ends?

The first, most common prejudice regarding plastic windows is a doubt about their environmental friendliness. For some reason, it is still often believed that the material from which the window is made can emit substances that are unsafe for both human health and the environment. How true is this?

In fact, this is a delusion from a number of common myths that do not have any evidence - either direct or indirect. Today, thanks to advanced technologies and the high quality of raw materials, proven recipes and well-established production processes, both PVC itself and its products are completely environmentally safe and do not pose any threat. PVC is a material that does not actively interact with the environment, air, and therefore can be used for glazing even children's and medical institutions. Moreover, today PVC products do not require mandatory certification or sanitary and epidemic permits, it is up to the manufacturer to make such checks or not.

Overcoming the public's prejudice against plastic proved to be a difficult task - the initial distrust of many consumers in everything "artificial" and "unnatural" had an effect. It took years of serious information campaigns for the consumer to finally understand and believe: plastic windows do not pose any danger to him, and the benefits from their use, on the contrary, are real and tangible. So, in the 90s, PVC was massively abandoned in Europe, giving preference to “natural” wood. The quotation marks in the word "natural" in this case are not accidental. Because quality is made of their material, which is subjected to fairly intensive processing, including chemical reagents. This does not make this material worse, it's just that it is no longer necessary to talk about naturalness. Ultimately, it turned out that the massive use of wood for windows affects forestry, and here polymers even act as defenders of the ecological balance, and not as a threat factor.

Therefore, you should not be afraid of polymers and plastics, and there is no need. More than 80% of all materials that form the life space of a modern person are connected with them in one way or another. They are used in medicine, the food industry and even in the manufacture of clothing; in general, it is almost impossible to find a "polymer-free" area in the modern world.

But there are also speculations of a different kind. So, some manufacturers of PVC profiles talk about some special "environmental friendliness" of their products, although all are environmentally friendly, without exception, regardless of the recipe. By focusing on the imaginary features of their products, such manufacturers distract the consumer from real, unimagined risks - for example, from the presence of low-quality thin-walled profiles in their assortment, which can most directly affect the quality of the window. But this red herring is an occasion for another discussion.

The second aspect of environmental claims is related to the answer to the question: what happens to the window "after death", after its service life is over.

Yes, indeed, a plastic window, like any product, any engineering system that experiences loads and impacts, has a certain margin of safety, a certain service life - as a rule, no more than 50 years. And then what?

And then the window needs to be changed, and this is where the environmentalists began to sound the alarm, insistently demanding to reduce the use of windows made of "non-natural" materials. The fact is that plastic does not decompose, and if the old PVC window ends up in a landfill, it can lie there for many, many years. For Europe, the problem of household and construction waste is a matter of practical survival - there is little space, but a lot of waste, more and more every year. This became especially relevant in the early 1990s. The first plastic windows appeared on the European market in 1954, and after forty years the time for their mass replacement began to approach. The window industry in Europe faced a real challenge: environmentalists sounded the alarm and demanded restrictive measures, but there was no ready-made solution. These plastic bags or other “simple” waste can be disposed of simply and quickly, but what about windows where, in addition to plastic, there is also a reinforcing amplifier, as well as seals, handles, hinges? By that time, technologies for processing glass and double-glazed windows already existed, but it was not clear what to do with a whole window.

The solution was proposed by the German, which developed and introduced in 1993 the technology of recycling, the recycling of a spent window. The only thing that had to be done beforehand was to remove the double-glazed window, which is processed separately. The old windows are then fed to a giant, toothy shredder that turns them into multi-colored shredder. The next stage after grinding is washing, after which a powerful magnet removes all metal parts from the resulting mixture, then special separators sift out the light parts of the seals, after which the regenerate is divided into white and non-ferrous. The recycling rate of a used window is 98%, and today VEKA already has three recycling plants in Europe, constantly and well loaded.

Let's summarize. environmentally friendly - whether we mean by this their harmlessness to health or the absence of threats to the environment in them. Attempts to challenge this, usually made for promotional purposes, do not stand up to scrutiny, but only distract the consumer from real, not contrived risk factors. Which we will talk about in our next articles.

The vast majority of information on the Internet is promotional in nature. It is quite difficult to learn from it what effect plastic windows have on the human body.

We will try to give the most objective information, in which the interests of the buyer, not the manufacturer, will come first.

To begin with, let's consider which PVC profiles manufacturers call "environmental" and why.

• Green line technology. This is the world's first lead-free plastic production technology. This metal has properties that are dangerous not only for human health: it is extremely difficult to dispose of, it accumulates in the ground and poisons the entire environment.
• The use of glass composite. The most modern innovative technology, glass composite is considered the safest among all varieties of artificial materials. 70% fiberglass and 30% inert thermosetting resins, high chemical stability.
• Wood is a completely safe material for health.

Used stabilizers for the manufacture of PVC

In the process of long-term operation, plastic is exposed to harsh ultraviolet radiation, sudden temperature changes, and the influence of organic and inorganic acids, which are present in small amounts in urban air.

In order for the physical characteristics of the plastic not to deteriorate, various stabilizers are added to it. Below we will consider how harmful they are and is it possible to do without them?

• lead stabilizers. Quite cheap, very technologically advanced, give plastic excellent performance characteristics. But both people and the environment suffer from them. No wonder there are warning labels on the packages with it. Most developed countries have banned the use of these chemicals at the legislative level. The presence of toxic substances is especially bad for children and pregnant women.
• Calcium-zinc stabilizers. They began to use more than twenty years ago, but only recently they are becoming widespread. These are more environmentally friendly components - sanitary authorities allow the use of plastic with this stabilizer without restrictions.

Plastic windows - benefit or harm?

It would be more correct to formulate the question: do plastic windows bring more harm or benefit?

Absolutely all chemical compounds emit evaporation into the air. The only question is their quantity, and what concentration the sanitary authorities consider safe.

But here there are already significant discrepancies, which depend on the honesty of state bodies and the capabilities of powerful producers' lobbies. It is they who convince consumers whether their products will benefit or harm.

New eco-friendly innovative window materials

The latest "peak of fashion" is the manufacture of windows from glass composite. As manufacturers assure buyers, these are the most environmentally friendly windows. Indeed, the glass composite releases the smallest amount of chemical compounds into the air, but, nevertheless, it releases. Therefore, it is also difficult to call such windows 100% environmentally friendly.

About ecology instead of an epilogue

In conclusion, I would like to sum up the “general struggle for the environment”. All the actions of mankind harm it, before we harmed less, now more. And almost all modern materials harm our health: varnishes and paints, plastics and inorganic resins, adhesives and artificial fibers. This is the inevitable price of progress, and this fact must be accepted.

If you don’t want to pay in this way, there is only one way out: everyone moves together to the caves, put on bandages made of palm leaves and eat only fruits and berries.

First of all, this concerns very zealous fighters for the environment, but for some reason they are in no hurry to make such a “tempting” decision…
