Dispelling myths about the panoramic windows

The five most common stereotypes about the panoramic glazing eyes of experts and users FORUMHOUSE

The material was prepared with the participation of experts of the company VEKA Rus

"Nothing beats the feeling when winter morning of Sunday standing with a cup of coffee in their hands in front of a glass portal and look at the smoke from the chimneys of the neighboring houses, on the sparkling snow... and you're in shorts and aromatic coffee "- so party FORUMHOUSE c nickname val-lel He describes the experience of operating the glass portal in the dining room of his country house.

Large-scale glazing elements - certain architectural trend of the last decades. "Windows on the floor", "endangered the walls" and other constructions of this kind blur the boundaries between home and the site, fill the room with light and give a feeling of freedom and comfort.

But so far, not only from ordinary consumers, but even professional architects and designers have some skepticism about large-format designs. Skeptics believe that the large form is always a great heat loss and lack of security.

It is not so - proved participants FORUMHOUSE, who built the house with such constructions, and never regretted it.

Experts of the company VEKA Rus disassemble for readers FORUMHOUSE persistent stereotypes about the panoramic windows: which ones are true and which are not.

• How to avoid heat loss when the panoramic glazing
• Why panoramic windows safely
• Why properly designed and mounted large-constructions possible occurrence of condensation

Stereotype №1. Panoramic windows - always a great heat loss through the glazing

Participant FORUMHOUSEs nickname Forumchanka from Eastern Siberia karkasnik wants to build a large panoramic window in the end (width 7500 mm, height of two stories).

Solar insolation, the city ranks second in Russia (after Sochi), but sorokogradusnuyu frost has not been canceled. FORUMHOUSE on this project approved, not all. No new posts wrote: "Well, yes, windows just for Eastern Siberia! Or you're hoping for the magic energy-saving insulating glass against the cold? ".

There is no magic, there is an indisputable fact: the production of insulating glass technology developed with space velocity.

Now, even the large-translucent structure with a large number of opening flaps is capable of providing heat resistance, comparable with the wall.

This design will work consistently well and for a long time. The main thing - to understand that this is not an "ordinary window blind, only large." This is a separate kind of translucent structures, which operates quite differently and always requires a competent design. And in such structures can not be put simple glazing.

Andrey Okulov

Head of «Veka Rus" company technical department

The design of the windows should be designed for wind loads based on wind region, the height of plant and the type of area (urban buildings, open area), the dimensions of the valves opening and weight of glass used, as heat and sound insulation requirements. The design must be easy and convenient to be operated, if necessary, provide special requirements for protection from hacking, child safety and protection from accidental loss.

The design of the glazing should take into account the requirements of heat and sound insulation, security and stability of the deformation.

The design of the windows and the room is necessary to provide the way will be airing the room, its heating and overheating protection.

If the decision is not a professional, then provide a comfortable indoor climate will not be possible.

Therefore, according to our expert, for all climates, you can choose the glazing so not only to avoid heat loss, but even to reduce them due to solar radiation.

Andrey Okulov

Solutions to such structures in the market a lot. Especially it should be noted in this context that a sliding-lifting construction VEKASLAYD width up to 6.5 m and 2.7 m in height and actually sliding "glass wall".

Stereotype №2. Panoramic windows - always a great heat loss through the profile

No, the heat loss through the profile will not be large, if properly pick it up. This depends on the design size.

Andrey Okulov

​Construction of the panoramic windows can be made of various materials, usually wood, aluminum and PVC profile. Each of these materials has its own characteristics that must be considered in the design.

PVC profile design allows to make in a single frame: 8 m² or, using special facade profiles substantially larger area. The design must provide for thermal expansion joints. Structure VEKASLAYD may have a height of 2.7 m and a width of 6.5 m.

The choice of material panoramic glazing is based on technical and economic comparison, taking into account the design of the design, colors.

Structure, a width of 7.5 m and a height of 2 floor is optimally made from aluminum profile.

Stereotype №3. Will increase heating costs

Properly designed panoramic windows did not significantly increase the cost of heating. For many members of our portal, which put the "window to the floor," sliding elements of large size, "disappearing wall" and others large-scale construction it was a pleasant surprise:

Winter has passed and I see: TEPLOPRIEMY from the sun is much greater than the loss. A room with a window as the day warms up, that is enough for the whole night.

The portal stands the third year (this winter will be the third). No additional thermal insulation did. Additional heating costs are not seen.

In the kitchen, two large windows, one of them panoramic. But more pluses - if most of the windows on the sunny side, it's a big saving on lighting and very warm even in winter.

Stereotype №4. Panoramic windows - it is not safe

Transparent design that visually blur the boundaries at home with the outside world seem to be vulnerable to intrusion. How not cool, and the glass - not concrete; throw a brick at him, and it fell apart. This is a concern for many homeowners who dream of sliding glass walls.

How can operate the thieves? Came up to the fence, threw a stone, glass spilled, come and take whatever you like. And if the glass is broken, it does not make sense to walk around and throw in all the windows.

In fact, the reason for this concern is not how our expert says, in a panoramic glazing you can use special glasses that are not amenable to such treatment at destruction.

And to strengthen the protection is a set of additional measures:

• triplex;
• film;
• shutters;
• alarm system (with stickers on the fence that guarded the house).

I Hardened eight and the film stands, mounting personally throwing bricks - normally holds. But I did it only for protection from small, he usually walks with a hammer, and so would cost the triplex.

Yet the strength of such glasses: our party portal with the nickname Apn8 jumping as on the trampoline, to "red-hot ten" size 2400 × 1200 mm, placed on the corners of the bricks.

I jumped to the ceiling, glass bent, but not broken.

Most participants chose the panoramic windows FORUMHOUSE considers such expensive solutions redundant, since in fact large-format design attractive to criminals any more than the usual small windows.

I think very few people for the theft will beat a huge panoramic windows.

Usually FORUMHOUSE to protect large structures are limited to triplex.

To cut a hole in the laminated safety glass 44.2, sufficient to penetrate into the house, we must zealously waving ax 10 minutes. During this time, even walking on skis arrive time to outfit police.

Stereotype №5. Panoramic windows - this is the inevitable condensation and icing

Condensation on the correct design and construction of large-format designs never happens. Risks can arise only if the design and installation mistakes.

Andrey Okulov

Since we have a great design, in addition to the calculation of glass on the thermal resistance, it is necessary to calculate its deformation resistance. If this is not done, from the difference in temperature and pressure between glass panes in the pane can distance increase or decrease, which may cause condensation or icing, as well as the effect of "Crooked mirrors." If the glass is chosen correctly, if done properly, the risk of condensation and ice formation is minimized.

One of the most common causes of condensation - the use of double-glazed aluminum spacer (low temperature at surface of the glass in the area of ​​the spacer) and the absence of circulation of warm air, especially in the lower horizontal parts design.

Andrey Okulov

When using spacers warmer in the pane (steel, TPS and m. P.), The risk of condensation decreases significantly (increase in temperature in the area of ​​the spacer).

Another solution against condensation - optimally matched the depth of the insulating glass unit. Depending on the mounting width of the profile can be chosen installation depth of 18 mm, 21 mm or 25 mm.

The deeper standing in profile glazing, the lower the risk of condensation.

Andrey Okulov

For panoramic walls and other large-format designs, we recommend to do the heat convectors. warm air stream directed from the bottom up eliminates the formation of condensation at any temperature changes. Our practice of exploiting panoramic designs shows that if it is done, no condensation and the more ice just will not.

conclusions

Panoramic windows, "disappearing wall" and other large-scale construction of several orders of magnitude increase the quality of life in the house: Scandinavian fashion chalet with large-glazed windows did not come out of nowhere - in these countries, as well as the majority of the Russian regions, and dark all winter cold.

Experience shows that such designs work well, add the functionality of the room and allow for the maximum amount of light inside.

Andrey Okulov

Panoramic windows - a very good and safe thing, but it must be handled competently and with a certain ability to design. It is in any case not the usual "grouse", which is done for cheapness and then bang - and decided to make a large-fixed glazing and everything will work well. If approached with intelligence, then there is no discomfort, and regrets the person does not receive, only the joy of a large amount of light and aesthetic pleasure.
