KEY CONSIDERATIONS WHEN SELECTING THE TYPE OF GLAZING FOR YOUR WINDOWS AND DOORS

 Double or triple glazing: (2 or 3 sheets of glass in the glazing unit). Triple glazing unit is almost twice as warm as a standard double glazing.

 Low-E glass in the glazing unit (if double glazing – one glass should be Low-E; if triple glazing – one or two glasses should be Low-E).

– uPVC warm spacers improves the thermal properties of the glazing unit. Warm TGI® and Thermix® thermal spacers are placed in all our window and door glazing units to prevent condensation at the corners of the glass units – this way the risk of dewing and mould formation on the windows is minimised. Made of uPVC and ultra-thin stainless steel foil, these spacers have very high thermal insulation, are mechanically strong, ultraviolet resistant and give windows a modern aesthetic look.

 Optimum gap between the glass in the glazing unit is recommended to be 12, 14, 16, 18, 20 mm. It is not recommended to choose a triple glazing unit with a spacing of 8-10 mm between glasses as thermal characteristics are lower.

 Gap between glasses filled in with argon, krypton or other gas. Double glazing filled in with argon gas is 20% warmer.

01 TRIPLE GLAZING UNITS

Spectrally-selective Low-E glass keeps heat inside the room and improves thermal characteristics of windows. You can reach the highest effect of energy saving when glazing windows with triple glazing units that are filled with argon. For this reason, triple glazing is used for buildings with high energy saving requirements. Also, triple glazing has very high sound insulation – as a result, triple glazed windows are the most common choice for the individual houses as it ensures comfort and saves energy.

ADVANTAGES OF LOW-E TRIPLE GLAZING UNITS:

– High heat insulation, reduces heating costs.

– Solar energy utilization – 63%.

– Suitable for Passive House.

– High sound insulation.

– Particularly high light penetrability – 79%.

– Does not change colour of passing and reflected light.

The maximum heat insulation is achieved in triple glazing units with two selective glasses, uPVC thermal frames between the glass 14, 16, 18, 20 mm. Glass units filled with argon gas. Such glazing units achieve a very good thermal performance with U=0.5 W/m2K. The warmer glazing units you choose, the lower are the energy loss and the lower are the heating costs.

 

02 LOW-E DOUBLE GLAZING UNITS

Double glazing units contains 2 glass joined together with aluminium or uPVC frame. KS selective glass (glass is covered with a special coating that keeps the heat) to further improve the thermal characteristics of the glass. Heat-saving glass units contains selective glass, filled with argon gas.

The heat transfer coefficient U of double glazing with selective glass can vary from 1.0 W/m2K to 1.7 W/m2K. The heat transfer coefficient U of double glazing without the selective glass is 2.7 W/m2K.

03 SOLAR CONTROL GLAZING UNITS

Solar control glass units are a hi-tech product that allows sunlight to pass through a window or façade while reflecting away a large degree of the sun’s heat. The indoor space stays still bright, but much cooler than in the case if usual glass were used. This is especially relevant for homes with a large part of the façade made of glass, and with large windows facing south.

– Solar control glazing not only protect against heat loss in winter, but also reduce the cost of indoor conditioning in summer.

– Solar control glazing visually almost doesn’t differ from usual clear glass, but effectively reflects sunlight.

– Solar control glazing reliably protect home from heat but provide sufficient light transmittance.

Solar control glass units also may be:

Mirrored (reflective). This glass is covered with a special coating that reflects up to 75% of solar energy. These glass units are mostly used for glazing commercial buildings.

Tinted. Glass can be coloured, grey, brown or green. Tinted glass units are often used in the construction of such buildings, where the area of ​​the windows makes a very large part of the building. Heat transfer and colour intensity depends on the thickness of the glass.

04 SOUND INSULATING GLAZING UNITS

Modern high-quality windows must protect the premises from external noise. In living areas the noise level should not exceed 40-45 dB.

To avoid or reduce the external noise for a comfortable living, it is recommended to choose sound insulating glass units that will ensure extremely high sound insulation and eliminate noise from the outside.

The glazing units components have their own resonant frequencies, so the use of different thickness glass sheets and the installation of different dividers significantly improves the sound insulation characteristics of the glass unit. In order to meet the highest sound insulation requirements, different thicknesses glass and space of 16-20 mm between them is used.

05 SAFETY GLAZING UNITS
Safety glazing units are often used in individual homes or commercial buildings to protect premises from burglary. The purpose of high security glass units is not only to protect premises against burglary, but also to protect against falling or breaking glass, as well as from flame spread in case of fire. In safety glass units at least one glass is laminated, hardened or reinforced.

Safety glazing units types:

Laminated glass (triplex) is produced by inserting a transparent, elastic film between two or more sheets of glass. This film holds the glass in place in case of braking and prevents glass parts from falling. Laminated glass can be 6, 8, 10, 12 mm thick and is much harder to break than non-laminated glass. Laminated glass helps to protect premises from intruders and theft.

Tempered glass is made with a glass sheet that is hardened by cooling the heated glass. This increases the strength of the glass up to 5 times. In case of braking, tempered glass instead of big sharp combs falls into many small cube-shaped pieces that have no sharp edges. Tempered glass can be 4, 6, 8, 10, 12 mm thick. Tempered glazing protects people from possible injury if they break the glass.

Reinforced (fire-resistant) glass is used to prevent the spread of fire through a window or door. Reinforced glass units also protect against flame, smoke and harmful gases. Reinforced glass is also harder to break than non-reinforced glass.

06 GLAZING PATTERNS AND TEXTURE

By choosing our windows and doors, you can choose not only the shape, colour, but also the pattern of the glazing units that will add the individuality and originality to your interior. Upon request, we can offer glazing units using a patterned, matte or coloured glass.

Enamelled glass also can be used in our glazing units, when the transparent glass is coated with a chosen colour, which is adhered to the glass surface at high temperature.

We can also produce glazing units with stained glass. Such glass units are used in churches, museums, or individual houses, emphasizing the specific details of the interior or exterior. In order to ensure good thermal characteristics, it is recommended to place stained glass in the tempered glass unit.
