What’s your difference between HaanGlas and other vacuum glzing?2022-07-28T11:03:39+00:00

HaanGlas vacuum insulating glass are fully tempered,Minimum 6.3mm, no evacuation holes and Max size 1500*2500,while price is much lower than our competitors,all these make us different.

Will the pillars inside the glass affect visual effect?2022-07-28T11:04:56+00:00

No.Our pillars diameter is 0.6mm with 50mm distance.They’re not noticed at a distance of 1.2M,wont affect visual effect.

For special applications ,we recoomend HaanGlas Basic which has translucent pillars .

Meanwhile our vacuum glass don’t contain evacuation holes,you’ll only see a round 12mm gutter in the glass.

Can I install vacuum glass on existing frames ?2021-12-04T13:51:23+00:00

Yes,our vacuum glass thickness is 6.3mm -10.3mm.It’s even thinner than normal laminated glass.

The vacuum glass can almost fit any windows frames ,whether it’s already installed ,or new constructions.

What shall I do if glass failed?2021-12-23T04:09:15+00:00

Please collect the photos and videos,as well as the size list to replace.

HaanGlas offer 15 years warranty,once confirming that it’s vacuum glass quality problem,we will replace and deliver glass for free.

How can I judge the vacuum insulating glass failed?2022-07-28T11:06:13+00:00

The main problem of vacuum insulating glass is glass spontaneous breakage,whether it’s caused by Nis or uneven pressure,or installation reason.

If vacuum glass failed, the pillars will drop immediately and in cold winters,condensation will appear inside the vacuum glass.

Haanglas offer 10 years warranty ,if glass failed,please contact us for free replacement.

What the glass U value means?2021-12-04T13:49:10+00:00

U value means the heat transmitted through the glass,the less the better.

Normal 6-12-6 insulated glass has an U value 1.65w/m2.k, triple glazing(thickness 48mm) with 2 low-E coating is 0.65w/m2.k.

Vacuum glass U value can be 0.47 w/m2.k-double silver low-E, 0.71w/m2.k- Online low-E.

Can I have different colors and light transmittance?2021-12-04T13:46:55+00:00

Yes,our vacuum glass coating database include single silver,double silver,triple silver,online low-E coatings with different light transmittance and SHGC.

Low-E coating on body tinted glass (blue,grey,bronze,greenetc)  is also available to suite different climate.

What’s the maximum size of your vacuum glass?2022-07-29T13:53:59+00:00

For safety & quality concern ,our recommended max size are:

3+0.3V+3 fully tempered vacuum glass:1000 *1500mm.

4+0.3V+4 fully tempered vacuum glass:1000 *2000mm.

5+0.3V+5 fully tempered vacuum glass:1500*2500mm.

Can you produce complicated vacuum glass?2021-12-04T13:54:48+00:00

Yes,despite normal 6.3mm,8.3mm,10.3mm, the vacuum glass can be further processed to be laminated vacuum glass,vacuum insulated glass,vacuum fireproof glass,vacuum BIPV glass,vacuum thermochromic glass etc.

What’s the price of vacuum glass?2021-12-04T13:54:27+00:00

Vacuum glass price is decided by the size varieties,project quantity,and project location.
