i selected JTL Soundproof Windows which cost me about rm22k++
q windows more expensive about RM26-8k++

Bro, how are the results ? Does JTL show you the dbA before and after ?

I'm curious too. How is the sound reduction?

it works on my balcony and both bedroom (reduce 70-80-%+/-) except my master room (reduce 40-50%+/-)which is maybe too close to the highway or installation didn't done property ?

you can use the app which is called "noisecapture" to judge it but the best way is you feel it yourself.....don't just rely on the device

bro it works....at least 70%+/-.just the spec, the high the spec the more expensive

if you are keen, install it one by one or seperately.....to be safe

🙄i just ask then to quote n gonna pay deposit already..
🤔how about the dust n wind?

Thx bro for the information. I have asked for quotation as well but the invoice is from one company while payment has to be made to another company. And have to pay 90% before installation. A bit scary. Is the same arrangement applied to u ?

I ended up with Q-Windows. They have all the prices on their website https://q-windows.com.my/window-replacement/condominium/ ... It's a lot of money but what a difference ... can sleep in peace again. The wife is happy

Bro, I didn't the price listing in qwindows website. Mind to capture screenshot ? I did call them but their need wet work to remove my old windows frame so I didn't proceed further

Edit : my bad bro, I did manage to find the price already

I can't find it. Please can you tell me how to get to the price list ?

It is not a price list. U go to their past project or refer there

Understand. Thanks.

Wondering can get the same results and almost the same product from any "aluminium windows and glass"shop (铝窗店) ?

I get to know that JTL product is all local hardware/local system but the price doesnt worth that much as you may get the hardware all in hardware shop. Compare with Qwindows, all their hardware and system is from germany. ( ps their boss is german guy tho ) haha.. I did it for my condominium near to jalan kuching, can have peaceful sleep. Although pricy but that makes the different especially the after sales service. JTL i heard from another friend of mine who choose him, gone missing after installation LOL nyway just sharing. cheers

most of them always pm me asking the result

so I am here to give some advice and maybe my view for this to assist the members here

all the product i think from china/local either JTL or Q Windows, even they claim it is germany products, the guy who work/or maybe the boss (i am not sure) with JTL actually from Q Windows , according to the JTL guy (that why i am not very sure who are right or wrong since both also tell me the different stories)


at first i was impressed with the Q windows product, the lady boss call me and (after I told i reject their offer since their sales ppl are not very professional) show me the completed work a few years ago within my condo

but it is too pricey since i need to install a few rooms including my living room near to RM10k difference

So I choose the JTL since he look most professional compare with Q windows (the sales ppl)

but it did the good job with my living room as well as other bedrooms except master room which too close to the highway

the rest you can feel the difference immediately after installation except my master room, i think only 20-30% reduce, very poor result maybe due to poor installation or product issue I am not very sure

even I complaint to him, it seems like he can not do anything for this ....unless i ask for new installation again, that mean i need to pay double but no one can guarantee it work

compare with Q windows vs JTL

since I have installed the JTL product and visited the completed work of Q windows which installed a few years ago at different block but same unit, I would say the products , Q windows is better quality than JTL

but JTL guy is very professional (maybe he is very good to talk ) he can bring the sound prof windows infront of you to explain to the concept this n that so n so

as for the Q Windows, the Sale ppl including the lady boss, they seems like no very sure about the product and concept they will sell to you

according to JTL guy who are actually the ex senior manager of Q Widows so he know q windows product very well


for my case, eg master room,

at first he suggest Laminated 12.38mm DaTintedrk Type II for my master room
but later pay extra RM500 to get better spec of Laminated 16.38mm


for the Q windows, they only provide me the spec of float lami. 10.76 mm, clear

(that one ady installed a few years ago was float lami. 20.76 mm, clear according to lady boss)

so, base on the price and spec I select the JTL


but question arise, how do I know which spec JTL provide to me? We unable to measure and identify this......12.38mm or 16.38mm?

and we only can base on our ear (dont use the device, it is useless) to ensure whether the sound proof work or not, and it is very subjective



so, after my case, I would suggest to you

if you need to install this, install one by one (they allow you to install just one windows for 1 rooms then later another room later) to see how good the result

rather than install together

and I am not sure what can I do in case you are not satify the result since it is very subjective but it works with my other rooms (70-80%) except the master room (20-30%)

i hope the reply will help those who are keen to install this

yes

don't think so.....it involve the good installation as well

Hi, can you share noise reduction especially for motorbike noises? Also how far away is your condo from highway?

Thanks.

Hi, I checked the website and it says the price is per piece. What does it mean by 'piece'? 1 piece of the window? Or a whole set of window?
