What You Need to Know About Double Glazing in PVC Windows

A double-glazed window consists of multiple panes within a single unit. Typically, these are units with dual glass separated by a stationary layer of gas/air and a spacer. Some manufacturers might offer windows with triple glazing. Essentially, nowadays, double glazing forms the core of uPVC windows, although the frame can be made of any material. Our window factory "Osnova" offers guidance on making the right choice when selecting a double glazing unit for your product.

Is It Worth Buying PVC Windows with Double Glazing

After installing single-glazed windows, a portion of heat dissipates outside, causing the units to become cold. If the product is installed in a room without winter heating, even at 10°C, the room will remain cold. uPVC windows with double glazing are the best option to tackle such a problem because they have multiple layers of insulation.

Preserving warmth is possible with double glazing. If there's not enough heat retained within the product to maintain an optimal room temperature, it's referred to as thermal destruction. This phenomenon might cause sags in window frames and even mold.

Advantages of Purchasing Windows with Double Glazing

For rooms facing busy streets, it's recommended to buy windows with double glazing. This option reduces noise, creating a barrier against sound waves. Such products help in retaining warmth. Some uPVC windows with double glazing can reduce noise levels by 10 dB. These products are typically made with thicknesses ranging from 0.3 to 0.8 cm with heavy or double glass, creating a layer of gas or air for insulation.

Windows with double glazing reduce thermal radiation and provide soundproofing. These quality products have a rating between 90 dB to 110 dB depending on the application area. You can also opt for a single-chamber double glazing filled with argon, providing the same noise insulation as a dual-chamber window but with air instead of gas.

Choosing Windows for a Flat in a Noisy Area

When selecting uPVC windows for a residence in a noisy area, consider double-glazed units with various glass thicknesses. They provide excellent sound insulation. You can also consider reflective glass, which has a special coating providing light reflection and a slight mirror effect.

If break-in protection is your top concern, buying uPVC windows with laminated glass is advisable. They consist of multiple layers of glass bonded together with a special adhesive tape around the perimeter. Upon impact, laminated glass does not shatter, thus preventing injuries. Due to this, such impact-resistant glazing units can be installed in children's rooms and on inclined facades as they withstand impacts well (precipitation, accidentally dropped objects).

So, summarizing the advantages of double glazing in uPVC windows:

• Good thermal and sound insulation.
• Impact resistance.
• Various types of glazing units to choose from - transparent, tinted, sun-protective, armored, etc.
• Modern design.

Cons of Double Glazing in Windows

Among the main drawbacks of uPVC windows with double glazing, buyers consider a couple of nuances.

Cost. On average, double-glazed windows cost twice as much.

Consider the pricing policy for products with double glazing if you have a mortgage, calculating the family budget for repairs and maintenance.

Is It Possible to Replace a Double-Glazed Unit in a uPVC Window if It Breaks

Technically, fixing such a problem is possible, but it might not be the best solution. Significant energy efficiency could be lost by replacing one pane in a double-glazed window. Any gas between the panes gradually escapes, leading to decreased efficiency levels. When replacing a pane in a single-glazed uPVC window, there's a risk of damaging the seal and the product itself. Seeking help from professionals is the most accurate solution in such a situation.

Nuances in Choosing Double-Glazed Units

Double-glazed units play a crucial role in windows. They determine not only the degree of interior lighting but also the amount of thermal energy they transmit. They also affect the thermal and sound insulation of the entire window.

A double-glazed unit filled with argon enhances the window's sound insulation. By technical specifications, a single-chamber argon-filled unit can be compared to a dual-chamber unit filled with air. Studies have shown that combining glass of different thicknesses also improves the noise insulation of these units. Thanks to this, we can enjoy peace even in noisy neighborhoods.

For windows facing the street, consider reflective glass. Reflective glass with a special coating provides light reflection and a slightly mirrored effect.

Impact-resistant units passively protect the premises from external intrusion. These units consist of laminated glass, where several sheets of glass are bonded together across their entire surface by a special adhesive film. Laminated glass doesn't shatter upon damage, ensuring protection from injuries. Windows equipped with laminated or toughened glass are recommended for use in children's rooms and on inclined facades as they withstand impacts well (from falling objects or hail).

Where to Order uPVC Windows with Double-Glazed Units

We offer a wide selection of glass types for your constructions:

Clear glass – standard polished glass;

Tinted - a semi-transparent colored film is applied to the glass surface;

Reflective (sun-protective) glass - glass with light-reflecting properties;

Toughened - regular sheet glass obtained by heating to the toughening temperature (650-680°C) followed by rapid uniform air cooling from both sides;

Laminated - multiple glass sheets bonded with a special polymer compound;

Armored (with protection classes SU-1, SU-2, SU-3) - a complex engineering product that, alongside the functions of a regular window, provides protection against physical attacks (mechanical break-ins, shots, etc.);

Allow yourself to go beyond standard window designs!

Conclusion

The type of heating and the size of the house can affect the complexity of ensuring optimal heating in winter. Windows are crucial factors in heating efficiency and heat loss. Glass products allow sunlight in during the warm seasons and block it during winter. Quality uPVC windows for business and other purposes will demand thermal insulation. We recommend a highly efficient insulator that will reduce the heat loss of the window system.
