Hi guys. I am planning to get either Q window or JLT to change my windows to noise insulation type.

JTL - 2 years warranty, slightly cheaper
Q-windows - lifelong warranty, rubber 10 years, costly.

Q WINDOWS looks ok, but JLT was criticizing Q windows that they are faking the products are from German, its actually from China. And it seems Q windows always cheat their clients and total poor customer service.

JTL product looks good too.

Please share your experiences!

You know; Maybe you should post this to Q-Windows. And see what they respond. You seem to fall agreed with what another seller of windows said.

You know bad mouthing in Malaysia is like a toxic scum exist out of sore loser who cant get the market.

Obviously q window gona defend. So i wan to hear it from customer themself. Cause im gona spend about 30k, would like to investigate carefully.

Thx

mind share where you get the source of JTL?

Aiyo it is like Apple phone, designed in carlifornia and made in China.

Nowadays CHINA BRANDs have even better products.

Powder coated; with aluminium vs UPVC.

Sound proofing only happens with double glazing. Single glazing still consider weak in soundproofing.

As normal construction quote; always cheaper...But the real deal is " You get what you pay for "

Thanks to all replies. Is there any problem with water leaking due to vibration. Cause i heard after fixing the window, they only apply simple sealen. But since we are usually located next to highway which causes the noise, will the vibration induce movement in the window frame, resulting in water leakage during rain?

Dear Ladys and Gent´s.
This is Andre from German Windows (former Q- Windows). I was not aware the existence of this forum here.
Just now a new client highlight this to me. First of all i´m very surprised to read so many fake information's about my company.

So let me clarify something. Hope this helps to understand what where we came from and what we are doing:

1. German Windows Sdn Bhd is a window manufacturing company fully owned by myself and my Malaysian wife
2. I started to manufacture windows in Malaysia in 2011
3. We transferred all the knowledge, technologies, setups from our associated company in Germany
4. Every window and door design is following European Standards.
5. We extrude our profiles mostly in Malaysia with suppliers working on our license.
6. Glazing´s are made form InnoGlass Malaysia. This company was the only one be able to follow our quality standards.
7. All hardware parts are Made in Germany, US or Italy. They are carefully selected to secure Life Long Operations.

In all these years German Windows Sdn Bhd (former Q- Windows) faced any legal issues. Either with clients or authorities.
Customer satisfaction is our target.
This means if a client is not happy with our performance we work harder until everything is in line.

Related to JTL Windows.
The owners name is Jeff Tang.

1. Jeffrey joined my company instantly after we opened our business in Malaysia
2. He was not aware about windows and doors. That´s why I provided him every knowledge to be a successful salesmen.
3. After approx. one year he left my company from one day to another by stealing all intellectual properties including customer datas
4. Since this time he constantly copied my catalogs, brochures, web pages
5. Most important to know, JTL is just a middle men. He lie to the clients by claiming he manufacture and sell a "Denmark Window". The truth is he is buying from different local Manufactures and re- brand there goods. Is just like you buy a "VIVO" phone and re- label and offer this as "SAMSUNG".
6. He provides a 2 years warranty. End of the day he is just a trader. How he want to fulfill this promises?
7. Of course JTL must be cheaper than German Windows (former Q- Windows). Cause the whole technology is 20 years behind our´s. The materials in use are mostly China Made. He has to finance his One Men Show only. In compare to a manufacture taking care a full Factory setup.

Never than less Jeff Tang is a very good salesmen. This make him survive even if his product is just 3rd world standard. In the manufacturing market his name is "cheating Jeff". I think this says everything.
If you have any doubts or further question´s, please contact my directly. Thank you! Andre

Anyway; I hope your status presence here make the difference; and It is a very interesting industry point out of whats going on. with multiple "copycats" and IP duplicator like JTL windows.

I wonder why didnt you filed for a lawsuit of your company rights against JTL? or was it merely waste of time?

In Malaysia; UPVC windows uptake is not far wide enough; am I right?

There`s VEKA, VINCA, FASCINA and Q-windows and dupster JTL.

I bought both from Q-Windows (what it was known back then) and from China. Each has their own qualities and I would say both performed well for the tasks that I wanted them to.

For me, the take-home message is to find out what you want your windows to function as? Soundproof, will need double glazing but if your wall material not that good, the sound will still pass through.

I choose Q-Windows for their European-styled tilt and turn window and also for the soundproof function.

As for the China ones, that's because I needed a bigger sized window for viewing purposes.

Q window for me..
it's function well the needs
No issues

and wow.. got the big boss reply here too..
I'm impressed

Filing a lawsuit is really a waste of time. From my point of view one day clients are experienced enough to reject guys like JTL.

UPVC windows are a good choice. Especially if you are looking for energy saving.
The material price is quite cheap. Therefore in Europe more than 70% of all windows are made out of uPVC.
For usage in Asian markets I have still some doubts. The UV light impact is really high.
In past a lot of discolorations where happening. But profiles covered with a "Renolit" foil are a recommendation.
If I´m not wrong FACINA offer this range.

Interesting feedback and response.

I am currently considering the replacement of windows and doors at my place with security glass and frames and don't plan to install ugly looking grilles anymore.

I have spoken to a few suppliers including Vinca and Fascina - both are uPVC types but they do come at a high price tag even though people say uPVC is cheaper than metal.

What's the main advantage of aluminium compared to uPVC ?

What is the main factor for one to choose between uPVC vs Aluminium assuming security is the #1 priority ?

Thanks!

The main advantage of uPVC is the lower heat conduction in compare to aluminium.
If you are looking for energy saving, installing uPVC windows makes sense. Of course only in combination with energy saving glass.

On the other hand uPVC is a very soft material.
Profile stiffness can only be realized with steel reinforcement hidden inside the profiles.
Most of the time manufactures saving costs by using as less as possible reinforcements.

And uPVC is one of the cheapest profile materials.
In Europe every government housing project is using uPVC windows.

High developed aluminium windows are much more durable.
Therefore private builders are looking most of the time for aluminium.
In public buildings with high visitor frequency is uPVC even not allow to use.

End of the day the combination of window material, glass and the related hardware is the key.
Laminated glass, proven hardware (especially multi- point- locking gears & security striker) and an solid installation method are needed to void grills.

Hope this helps a bit ...

I wonder if you you also provide security option after the window part? Something like storm shutter in Japan. For example in this Link. Preferably something stylish and modern. Something that can be operated from inside the house. Its better if it runs on electric and can be opened/closed with a switch.

Hello, that´s an interesting product. Will check with or R&D how to develop something like this. Currently we do only SUN-SHADING sliding louvers. Like attached. Thanks for this idea!

Hi Andre, I was trying to get quotation from your company to replace the toilet window to casement window and I was told there is a minimum order of RM10k. Hence, no quotation will be given to me. Maybe you can specify there is such requirement in your Facebook page and also website, otherwise there will be people like me engaging your end for nothing. Thanks.
