Studio Window Construction, Preconstructed or from Scratch?

Anyone ever heard or TruAcoustics? They make windows, and I am serioulsy considering buying one from them. They have a kit that includes frame and glass. The prices are posted below incase anyone cares. I just wanted to hear from you guys first. Pros cons? Since I didn't find anything in a search no ones ever heard of them. 2’x4’ of the STC 45 Model $1,198 + crating=$79 + our shipping cost 2’x5’ of the STC 45 Model $1,384 + crating=$79 + our shipping cost 2’x4’ of the STC 56 Model $2,147 + crating=$79 + our shipping cost 2’x5’ of the STC 56 Model $2,415 + crating=$79 + our shipping cost.

It is actually a 1” thick glass unit with two pieces of ¼” laminated glass slanted down and then an additional piece of ¼” laminated glass vertically positioned. The frame is sealed with an acoustical caulk that we supply. I do not feel that you will need the suction cup handler.

Well I don't knw the company - but i do know that their note is bul*s**t. Rod

Thanks for the reply. I have been feverishly scanning the internet for pics of "Cntrl Windows" to see if they are slanted downward or upward and they ALL slant down. This company's window oddly enough, slants upward. I did see your reply on my previous post with reagrds to the same issue. I posed this question to this company and I was fed a B***hi*t answer as far as I am concerned. So the hunt continues.

it's not the direction the glass slants thats off. . .its the fact that it does slant for 'maximum stc value' if the glass was parallel and vertical with a gap as much as the larger gap of a slanted window, the stc value would be BETTER. not to sound redundant throughout the forum, but GET ROD'S BOOK! he goes into GREAT detail about windows. you'll make one WAY better than this, for WAY cheaper.

Sorry about all the confusion, I should have included the entire picture which more completely displays what the mfg was trying to express. There ARE two pieces of glass here and that's is the jist of what they were refering to I believe.

The point is that it is the mass + airgap + internal damping material that results in improving STC (and LF TL). Slanting the panes has a determental effect on STC due to a reduction in airgap size. But, I think it can affect the coincidence dip...but that can be countered by using different pane thicknesses (which is usually done anyways). The main reasons for slanting the glass have nothing to do with STC...it's done to reduce both visual reflctions, and high frequency audio reflections. Cheers Kris

John, you are misreading the picture and their verbiage. There are 3 pieces of glass in their product. There is first an insulated unit..... 2 pieces of 1/4" laminated glass over a 1/2" air space - and then an additional piece of 1/4" laminated glass. So you didn't cause any confusion in my mind......

Ok, I get it. So where does one get a window pre fab?
