double glazing in alu frame?

Postby rob28 » Mon Apr 14, 2008 4:21 pm

I wondered if it is possible to put double glazing in an aluminium frame.
I want sliding doors that are sound proof. the thing with the vinyl frames is that they only come in white and i don't think painting them will look nice.

Bump

I need black frames that are double glazed too!

from what I've seen all around.. double glazed windows in thailand are rare.. and only available in upvc, white color.
this double glazed have to be made in factory and the cheaper i've seen in shops like "global" is the chinese stuff.. that I think is s**t.. specially the lockers system..etc..

In europe you can have double glazed in alu or wood.. if your budget is not a worry then you can have all the european / american stuff as well here.. but on a budget price you may have to go for upvc.

also think about your walls... do they fit the thermic and sound proof standart to include double glazed windows if not it will be a loose of money only to install this on a one line brick wall for example.

hope I help a bit ^^

After a bit of research it seems the most 'sound proof' way to go for windows is a casement system rather than sliding - no matter what glass is used the 'seal' between frame and panel will always allow some sound through. Depends on how much noise you need to cut out.

its a gidday to H. and all..its the thai fly from mae rim....double glazed ...WINDOW.. units have been around since the... DAY DOT. :) . for the average modest budget build..particular on C.T.H. .they are a expensive item :!: :!: ..and by choosing another alternative..the money saved can be used in better ways.. :P :P ..but if you have sh.t load of baht go for it 8) 8) its .. a go go CHELSEA F.C.TOMORROW..GOT PLENTY ON ..GIDDAY TO ALL..its the thai fly from mae rim

Here in Thailand we deal with a temperature difference of about 10 to 15 degrees C inside to outside to stay comfortable. I think the cost of double and now triple glazing is not worth it for this difference. A double glazed casement window with clear glass has an insulating value of R-2.0 (U 0.50) single glazed has a value of R-1.0. Keeping the sun off walls and venting attic space should be the most cost effective solution here. Just to put it in perspective the insulating requirements for walls and ceilings in cold climates, R-19 in walls and floors: R-38 to R-49 in ceilings below ventilated attics. That leaves the R-1 difference for window quite small.
Bests spend the Baht on insulating block. foil under the tile roof and a few trees. IMHO.

Well said BKKKBILL and on the button -- take account of the Sun's path, throughout the year as it moves between hemispheres, when you place your windows and if some are essential in exposed locations incorporate shade in your design or plant a tree and help save the planet. Always worth a little extra for tinted glass due to reflected rays but more than this is not necessary; unless you have a noise problem as well.

Hey thaifly - Not saying casement is way for everyone but the most 'noise proof' system will be a casement system rather than sliding - single,double or whatever glassing and what ever frame ali or uPVC. Of course you pays ya money and takes your choice!

Just a little more on windows. MGV12 brings up a good point about tined glazing. Put film on my car windows a few years back and there was a noticeable difference. To cut heat gain, select glazing with a high shading coefficient. Glazing with a high UV value will block nearly all furniture-fading ultraviolet rays. My last house in Canada had Vinyl double glazed windows with low-e glass a virtually invisible metallic coating that blocks radiant heat transfer and protects carpets and furnishings from fading by reducing damaging ultraviolet rays from the sun. These were classed as “Super” windows having two low-e coatings to achieve incredibly high R-8 insulation values. I don’t know how much of a difference this or solar bronze and solar gray tinted glass will have with single glazing but I’m sure there will be some.

Sound control often seems like a fickle science. You can have a door or window with a very good STC (Sound Transmission Class) completely compromised by air gaps around it. A 1cm gap under a door that should be good for a sound reduction of 40 dba may be reduced to 12 db or less. Good sound reduction needs good, non-resonant, high-density materials, 100% sealed (air flow silencers are an exception but need to be well designed).

Most sliding window designs have so many acoustical leaks that the STC of the glass is of less consequence. A well-designed and properly gasketed and caulked casement window will be much more effective in reducing sound transmission.

Double glazing, where sound control is the objective, is probably not going to achieve the desired result in sliding window designs.

Basically, sound is low pressure fluctuations in air in frequencies between 20 hz and 15 khz. If a structure isn't low pressure air tight, you won't get the maximum benefit of the sound transmission loss of the materials being used. The lower the frequency of the sound waves, the more difficult to attenuate.

Seems that I will have a bit of a learning curve on this subject. Our house is close to the temple/wat in town and there is the usual loud speaker system.
One morning well before the sun was up 05:18 to be exact, some *&%%$#*&& was giving a lecture about ???? then the music started, but I was woken up by the roosters and dogs about 04:30 anyway :( :( :(

Moral of the story is our master bedroom will be as sound proof as possible. Double block walls and double glass windows, along with super insulation, and to heck with the costs...................

Don't rule out glass blocks. They may not open, but.

Another major problem for noise is through the ceiling. That needs to be done 'right' if you are looking for quiet in a noisy neighborhood.

Makmak456,
Yesterday whilst we took delivery of some Thai furniture the large temple across the paddy fields decided to test its massive new PA system that everyone could hear as we had the doors and windows open downstairs. I went upstairs to see what the difference was and I heard nothing at all until I opened a sliding glass aluminum window. It may help you in your choice of replacement windows.

Runker,
Might be able to better that; when I first arrived in Vietnam (1968) I was sent to 1ARU where my tent was directly in line with the 175 mm guns of Heavy Output. Every time the guns would fire a fire mission to the north, all the tops of the metal "thunder boxes" would lift and fall back, at the same time everyones' "beds" would also lift about 4 inches off the wooden floors. The pressure force/wave was so great it would destroy sandbagged walls and bunkers in weeks. I can't remember anyone complaining, probably because it was American "friendly fire".
