FAQ about insulated glass

1.High SC and low SC,which one is better?

Glass with different SC are suitable for different climate areas.Higher SC will decrease the heating costs in winter by allowing more solar energy through the glass,this glass suites for long winter areas.Lower SC value will decrease the solar energy and suits for hot areas,such as middle east,Southeast Asia.

2.What’s the feature of low e glass.

a.High infrared reflective.

b.Low e value,with low capability of absorbing solar energy.

c.Various SC value to match different area requirement.

3.Why low-E glass can reflect solar energy?

There’s silver layers inside the low-E coating ,and can reflect 98% far infrared solar energy just like mirrors.While the adjustable SC can adjust the solar energy that transmitted into the room.

4.What’s reflective glass?

Reflective glass is a kind of coated glass,after coating the glass SC value decrease from 0.98 to 0.2-0.6.

5.What’s the difference between solar reflective glass and low-E glass?

Solar reflective glass limit the solar direct energy through the glass by decreasing glass SC value,while low-E glass limit the far infrared energy through the glass,and low-E glass has adjustable SC value.

6.What’s the energy transmitted the glass?

a.Solar direct energy,SC value means the direct solar energy transmitted the glass,lower SC,better energy saving effect.

b.infrared energy and far infrared energy.Low-E glass can reflect most far infrared energy and the insulating spacer will also decrease the transmittance of energy directly through the glass.

7.What kinds of popular low-E type?

a.Hard coated low-E with E=0.28,it can be used in single glazing,can be made into tempered glass,laminated glass and insulated glass,but its energy saving performance cannot match off line low-E.

b.Soft coated low-E,also named off line low-E,the best triple silver low-E can reach over 2.2 LSG ,and E below 0.05.

8.Which glass surface shall we place the low-E coating on?

The low-E coating position affect the SC value but has same U value.When low-E coating on surface #3,the SC value will be higher.So in cold areas,it’s recommended to place the coating on surface #3,in hot areas,place it on surface #2.

9.How much UV the low-E glass can barrier?

Low-e coating can obstruct around 25% UV,it cannot resist 100% but can decrease the fading of furniture.

10.What’s the lifetime of low-E coating?

The low e coating lifetime is same as the insulated glass.When the low-e coating is exposed in the air,it will lost energy saving performance within short time.

What’s the difference between XPS, EPS,PU?

For structural insulation panel ,EPS,XPS and PU are mostly widely used core,many clients don’t know exactly what materials they are ,what advantage and disadvantage of different core,here we offer some info:
EPS:Expanded polystyrene.Mixing polystyrene resin with foaming agent, after heating processing,the resin will forming a rigid closed-cell foam.

Structural insulation panels (SIP) WITH OSB and EPS board

XPS:Extruded polystyrene.It is continuously extruded and foamed by a special process. The hard film formed on the surface is even and flat, and the internal closed-cell foaming is continuous and uniform, forming a honeycomb structure.

Structural insulation panels with MGO and XPS board

PU:Polyurethane panels, made of isocyanate and polyether. It is polymerized by high-pressure spraying and on-site foaming under the action of various auxiliary agents such as foaming agents, catalysts, and flame retardants. There are two types of polyurethane foam: soft foam and rigid foam. Soft foam is open-cell structure, hard foam is closed-cell structure.

PUR PANELS
Comparison of XPS,EPS and PUR.
1.Thermal insulation: PU -0.022W/M2.K <XPS 0.029W/M2.K <EPS 0.042W/M2.K
2.Price: EPS <XPS<PU.
3.Temperature resistance: EPS 70℃< XPS 95℃<PU 120℃。
4.Compressive strength： EPS 69 MPA < PU 150Mpa <XPS 200Mpa.
5.Bonding strength:EPS<XPS<PU
6. XPS,EPS and PU all are flame retardant materials.

With above info,we can see that EPS has the best price but every performance is worse than XPS and PU.It’s suitable for low requirement,low energy saving performance requirement and low wind load projects.
PU has the highest price and almost best performance at every aspect,so it’s widely used in high energy saving projects.
XPS has the best cost performance,good thermal insulation,god water and moisture proof ,annd excellent compression performance,easy installation,so XPS is most common materials used in SIP.
Morn can supply all kinds of structural insulation panels with OSB and all kinds of core materials,welcome contact us for your next great project,we would like to be your reliable China SIP manufacturer and supplier.

Next: How the glass U value been affected by the installation angle?

How the glass U value been affected by the installation angle?

In most projects,glass is installed vertically.With high performance silver low-E coating,the insulated glass on the vertical facade will decrease the solar energy transmitted the glass,and save air conditioner heating and cooling fees.
While many architects have designed many unique facades,the facade is not 90° vertically,but with some slopes,and glass is also used in skylight to get more light transmittance.But will the insulated glass thermal insulation performance change in this situation?
Here is the result we calculated with Berkery LBNL window 7.5,based on solarban 60.

As we can see,the glass tile angle from 90° to 0°，there’s almost no performance difference despite the U value in Winter,it increase from 1.67 to 2.47W/M2.K.
So we can see ,in winter ,especially cold areas,the insulated glass angles will allow more heating going out the glass and increase the interior heating costs.While the tilted glass,especially the skylight glass will allow more solar energy energy transmitted therough the glass,so designers should consider and balance this issue when designing .

How about the laminated glass?Let’s take 6+1.52+6 clear tempered laminated glass as example：

LAMINATED GLASS PERFORMANCE DATA-MORN BM — As we can see,the glass installation angle affect glass U value much,so don’t forget calculating the glass U value when glass is not installed vertically.
Morn is your turnkey laminated glass and insulated glass manufacturer and supplier from China,welcome contact us for more info.

with the glass installation angle decrease from 90° to 0°，different from insulated glass,laminated glass U value decrease both in winter and summer.Other performance data,light transmittance,reflective,solar transmittance,SC and SHGC all change very little.
As we can see,the glass installation angle affect glass U value much,so don’t forget calculating the glass U value when glass is not installed vertically.

Next: Decorative cross bars for insulated glass

Decorative cross bars for insulated glass

Most insulated glass are supported by aluminium spacer or stainless steel bar, or warm edge space bar at glass edge to support and bond the glass.This kind insulated glass is widely used in glass facade,high rise glass cladding,while in some small villa,and low rise buildings,clients would like to add cross bars to decorate the glass and make it more beautiful.

Decorative cross bar is also made with aluminium profiles,Different from aluminium spacer bar,it’s used in glass middle,or glass center,it doesn’t support the insulated but only have decorative function.

Feature of decorative bar:
1.Various colors are available to match the windows frame or facade colors.The decorative bar color can be bespoked.
2.Decorative function:It will change the windows style and make it typical Chinese traditional or western Church styles.
3.Flexible shapes:it can not only been made into cross shape,but also many different shapes to create unique patterns.
4.Cheap price.The thin aluminium bar weight little,it won’t increase insulated glass weight much but price is relative low.
5.Long lifetime：The joint point is treated smoothly ,and strong,lifetime is same as the insulated glass.PVDF or powder coated surface also increase the bar life.
6.Compared with normal insulated glass,the aluminium cross bar installation is same.
7.Low-E coatings is also available for insulated glass with cross bars.

Next: What’s the difference between back painted glass and silk screen glass?

What’s the difference between back painted glass and silk screen glass?

Both silk screen glass and back printed glass are widely used in interior and exterior decoration,but what’s their difference?

1.Thee function difference.

Silk screen glass

a.Compared with bricks,stones,ceramic tilts,silk screen glass is cheap and simple.

b.Various colors and patterns.It can be silk screened with various colors to match the curtain wall color.

c.Easy cleaning.No absorption,no color changing.

d.The non-organic inks will not fall or fade after installation,the colors won’t change and last long time.

e.The silk screen surface and absorb and reflect certain solar energy and energy efficient.

f.Silk screen glass are all heat treated glass,after tempering or hat strengthened,the glass strength will increase much.

g.The silk screen glass can be further processed,such as laminating,coating,insulating process.

Back painted glass

a.Excellent waterproof, acid and alkali resistance.

b.Excellent anti slip performance.

c.High bonding strength and won’t fade.

d.Various color options.

e.Easy cleaning.

2.Other difference.

Silk screen glass ,the non-organic inks will be melt and bond together with the glass surface after tempering process.

The high temperature in tempering furnace 680-720 degree will guarantee the color won’t fad or fall from glass surface.

Back painted glass:It use low temperature inks,the heating process use only 100-150 degress .The paint just bond on glass surface ,so the paint will fall if we scratch with sharp corners.

3.Price.

Silk screen glass process include cutting-polishing-silk screen-tempering ,so it price is usually USD6-8/SQM higher than tempered glass.

Back painted glass don’t contain the tempering process,and the painting fees is lower than silk screen process,so the price is much cheaper than silk screen glass.

4.Silk screen glass cannot be cut after tempering process,it’s suitable for exterior cladding application ,while back painted glass can be cut,and process at suit to suit different requirement.

Generally speaking,silk screen glass is widely used in exterior especially curtain wall,while back painted glass is used in interior ,shower rooms,cabinet,furniture.
