Tony Angel of ‘Sound Barrier Systems’ changed my life. After searching on the internet and making lots of calls, I decided to go with these guys. The systems that Tony installed changed everything! I am now able to get a great night’s sleep. It has also insulated my apartment making it warmer in winter/cooler in summer, saving me money on energy bills! Thank you so much Tony, I am recommending you to anyone that needs noise reduction windows.
Warm Regards Shiraz Valdes

Hi Tony,
HAPPY CUSTOMER!, just thought I would let you know that we are very happy with the windows, the jets have been very active and the noise reduction is very evident. We now can watch the TV without even turning it up while the jets go over.
Thanks again,
Jonette Duchatel

Dear Tony,
I am pleased with the quality of the installation and your advice as to what type of construction would look good turned out to be correct. The resultant noise levels represent a substantial improvement and are as expected. Overall, a good outcome.
I didn’t tell you previously that I am an acoustic consultant and I would be pleased to recommend you if a client has such a need.
Kind Regards
Barry Murray, Wilkinson Murray

Hello Tony,
I just wanted to say that I am so impressed with the result and the overall install by yourself and your team members. Christian said it would be good but I had no idea how truly effective, sympathetic and generally unobtrusive the final look would be visually. It is phenomenal.
Best Regards
Denise Suo, Randwick

Good afternoon Tony,
Thank you for the professional job your company has done at our son's house in Marrickville, with the replacement of the windows.

Dear Tony,
We are most impressed with the work you have done and are pleased it has made the noise reduction we wanted without detracting from the character of the house.
Thanks and Best Wishes for the Future

Tony,
Thanks for a great job! I discovered on Friday morning that the reason I had not previously set an alarm clock has obviously been because the traffic wakes me up. Must have worked well as I slept in and now have to use an alarm clock.
Thanks Again
