LAMINATED GLASS

 Laminated Glass is combing two or multi glass panels with interlayer under high temperature and pressure.The interlayer can be EVA,PVB,SGP or more to bond glass permernantly.Te biggest advantage of laminated glass is its safety,once any glass beakage,the interlayer will keep glass integrity and prevent injury.Laminated glass is widely used in glass balsutrade,balcony,glass skylight,poolfence,glass facade.

HEAT TRHEAT TREATED GLASS

 

Heat treated glass,is glass that processed with tempering furnce .With the 670-720℃ and fast cololing process,the surface and interior compression changed and keep relatively balance.The heat treated glass strength is always 2-5 times that of float glass and prevent possible injury.Heat treated glass is used in balustrade,balcony,poolfence,point supported glass facade etc.

Why we use triple silver low-E on your facade?

Currently single silver low-E cannot meet the architectural energy saving requirement,the new double silver low-E and triple silver low-E ,in addition to the argon filled glass,triple glazing has decreased the glass U value significantly,especially the passive glass,through argon filled triple glazing with two pieces double silver low-E,the glass Uvalue has decreased to 0.6W/m2.k.Triple silver low-E has been more and more popular,then why shall we use triple silver low-e in your facade?

Why we use triple silver low-E on your facade?

The advantages of triple silver low-E:
1.Triple silver LOW-e IGU has higher transparency and low-E solar shading coefficiency.Based on same light transmittance,triple silver low-E has 15% lower SC than double silver,which is 15% better than single ones.
2.Thermal insulation.Based on same light transmittance,the far infaraed transmittance of triple is 3%,double is 11% and single is 31%.
3.Triple silver low-E has the best cost economy.The costs used by air conditioners for buildings using triple silver low-E is only half of double silver low-E and 30% of single silver low-E.
Morn now offers several different types triple silver low-E for clients:
MWTE58,which is similar as solarban 90.
MWTE70,which is similar as solarban70XL.


Based on same glass performance,our tripleilver low-E price is much better ,Morn is your turnkey architectural glass,especially triple silver low-E insulated glass supplier from China,welcome contact us for more info.

How laminated glass is made?

Laminated glass is widely used in glass facade,blustrade,glass fencing,canopy,glass skylight ,etc.As safety glass,laminated glass is made with 2 lites single piece glass and interlayer(PVB or SGP interlayer).
The interlayer can bond 2 piece glass together and keeps glass integrity once broken,it offers high security and avoid hurts.
Laminated glass is usually produced with glass laminating line,then how the glass and PVB interlayer bonded together?
Laminating line consist of glass loading table,glass transmission conveyor,washing and drying machine,glass positioning machine,waliking suction hanger,PVB storage shelf,pre-pressing machine,unloading table,infrared heating autoclave.
Glass is loaded onto the tansmission conveyor through automatic loading table ,after washing and cleaning process,the glass and interlayer was placed orderly,and with pre-pressing process,the PVB and glass is bonded temporary,then glass is removed to the autoclave keeping for around 8 hours to make the PVB and interlayer bonded permanently.
Here is a detailed video showing how laminated glass is made,the video is from China famous laminating line manufacturer-Lewei.Thanks for their detailed introduction and innovation that makes laminating glass a easy work.

What’s the difference between double glazing and triple glazing?

Most glass used in facade is double glazed units, which is made of 1 piece low-E coated glass and 1 piece clear glass,the most common glass combination is 6 low-E+12A+6 clear glass.
If the low-E coating is double silver low e coated,glass U value is around 1.6W/m2.k,for triple silver low-E the U value is same but will with lower Solar coefficient.Evne if we change the 2nd glass to double silver low-E,the U value won’t change much.

With the development of energy saving conscious,triple glazed units is widely used in developed countries ,such as Europe and North America areas,the cold area has higher heat conservation performance.
Compared with double glazed units,triple glazing has much lower U value ,glass made of 1 piece low-E and 2 lites clear glass U value can decrease to 1.2W/m2.k.Of course we have many options to decrease the U value again,such as increasing the iar gap ,fill argon,using warm edge spacer,and using 2 piece low-E glass.
The main difference between double glazed units and triple glazed units is U value,here is the comparison between different combinations.

As shown in above chart,triple glazed units can decrease 20-30% U value,taking advantage of more method,the U value can decrease 100% again ,the glass will be applied in passive buildings.

What’s the thermal conductivity measurement unit?

When evaluating the thermal insulation performance of a glass product,we usually know that clear& tinted single piece glass is 5.84,Single silver low-E insulated glass 1.8,and double silver low-E is 1.55-1.65.The lower the value,the better thermal insulation performance the glass has.
But What does the value mean and the measurement unit?
Actually the measurement unit is W/M2.k,which means watt/square meter/Kelvin,it’s under same confirmed air condition,the heat transfered throught the glass products.
While even this measurement unit,there’re many different conditions depend on different client.

The most widely used condition is American LBNL Ashare NFRC 100-2010 SUMMER standard:
Room temperature: 24°
Outside temperature: 32°
Glazing oriented windward, wind speed: 2.75 m/s
Sky temperature: 32°
Sky emissivity: 1.0
Incident solar power: 0 W/m2
NFRC 100-2010 winter standard:
Room temperature: 21°
Outside temperature: -18°
Glazing oriented windward, wind speed: 5.5 m/s
Sky temperature: -18°
Sky emissivity: 1.0
Incident solar power: 0 W/m2
While in European areas,they use another standard:EN673,there’s no summer and winter difference as there’s not big difference between winter and summer temperature.
Despite W/M2.K,there’s another measurement unit that shows the thermal conductivity :ft2•h•°F/BTU ,which means hour/square foot/°F.
It’s quite different unit.Sometimes clients mentioned glass unit is 0.3,many sales don’t believe this and think it must be incorrect and the glass U v value couldn’t be this low.While what the client mentions is hour/square foot/°F,not W/m2.k.
To transfer the unit, 1hour/square foot/°F =5.68w/m2.k,so don’t make mistake.
