Glass Performance, SHGC, tinting and LOW-E

[@martiruda]

Amazing video. Best advise is to take samples and spend a good week or two with them. We did this for the tinting we chose for our house. We naturally felt inclined towards using the light blue tint. it makes the outside colours look way more natural than greenish, brownish, greyish and even yellowish tinting options we got provided. Most important is realizing in cloudy days the non blue tinting performs very bad. The downside of the tinting with a colour is that this is a reflective film so at night when lights are on the house becomes a mirror. But this is a trade off like anything in life so we are really happy with the Choice. go Blue!

Thanks for sharing. I'll never forget how to explain Low-e coatings again! :D

[@RBBBBBBBBB533]

Very well explained. Thank You!

Good discussion about the coatings and tinting of the glass. Could have also discussed the affect of thickness of the glass and the spacing in igu. Finally a discussion on the importance of the frame to the overall performance of the window. A lot of Australian manufacturers still use aluminium frames that negates any benefits from double glazing.

The window frames had been discussed previously in this video: kzbin.info/www/bejne/r3vOlKOMgruCZ6csi=s-uhDlaQ1y7d-Ptx

A nice primer/crash course on this important topic. The professor was trying very hard not to use technical terms, but it’s a scientific topic.. there’s no way around it. By the way, is there a website to go to for more details? Thanks.

Beautiful LECTIO MAGISTRATES was explained by a great professor whom I personally know.

Great video. A bit on the longer side but worth every minute. I learned a lot. Thank you

What a great segment with your professor. It's really difficult to know which vendor I can go through locally who will understand enough about the right kinds of glass and isn't just going to steer me to whatever gives the greatest margins... it's really quite frustrating. I moved into an older house last year and we are slowly improving it. Since it was an architects house for him and his wife, it is very well built and insulated... but the windows are awful, and waves of cold roll off them, even with heavy curtains. Trying to find that sweet spot in price:performance is really difficult. Do you have a video on being able to measure what gains you might expect out of choosing performance glass? Trying to figure out if there is some equipment I can hire to take a bunch of readings myself to understand where my house is at, rather than hiring a person which is often substantially more expensive.

How have you got on so far? I am in your position also Being offered low e glass not sure whether its worth it

[@UnkleSi]

Thank you, great video. Can you give an example of how much heat low e glass can save (in a cold climate) vs the other types of heat loss through the glass. Ie - what percentage of heat loss is due to emissivity? I'm looking at dbl glazing (in nz) and not sure if low e is worth the expense. Thanks again, Simon

[@martiruda]

Hey mate, I'm in NZ from the very south! low-e is a must, trust me. you can stand up next to the window and the sun's heat won't bother you much. However, I put triple glazed windows with low-e, you notice the difference. The percentages are going to be a bit tricky thou.

[@frankp9573]

Joseph... Can you compare vacuum insulated glass to gas filled. Apparently its a new technology more efficient.

[@josephcheung8311]

The performance comparison can be based on the published U-value data. Just to be sure both products are presenting with the same U-value (metric V IP). Personally, unless in retrofitting project which the glass thickness is restricted. I would go for DGU instead of vacuum glass; mainly because DGU will still perform well when the seal between layers is broken. Not the case for vacuum glass.

[@frankp9573]

@@josephcheung8311 yes thank you for the response and advice.

Triple pane windows are common in Europe and are becoming more common else where. Single pane windows were common in the 1930s. Double pane windows became more common in the 1950s. Triple pane windows are now more common in the 2000s. Energy efficiency matters. Wasting energy wastes money. There is a climate crisis. Triple pane windows need to become the standard.

[@givemethejob3293]

Or V glass, vacuum glass thats only a fraction thicker than single glazing so can fit most old windows without changing them.

[@jenfizz4312]

Lol not in NZ lots of houses still have single and new budget houses have Doble but aluminum frames so still cold and condensation sad building practices ...ill stick with my 20s casement windows and retro fit double glazing
