Had our window openings enlarged and installed in our bedroom by Renewal by Andersen a couple of months ago in Toronto. We noticed that the windows make a crackling sound like popcorn when exposed to direct sunlight, with the more sunlight the crackling is more frequent.
Link to a video below showing the noise. Does anyone know if this is normal? We contacted Renewal by Andersen and they just said it was normal. There is absolutely no noise at night or when there's no sunlight.
Worked for New Home Warranty for 5 years and thought I had experienced every kind of construction complaint, but this is a new one. You may have come across something that is a true can of worms.
Interesting thing about window replacement projects is they probably don t require a building permit, however the windows still need to meet minimum Code requirements. Just had a look at the suppliers website and saw some things I ve never come across before (Fibrex material) and am not familiar with. Windows are required by Code (article 188.8.131.52.) to conform to:
a) AAMA/WDMA/CSA 101/I.S.2/A440, NAFS - North American Fenestration Standard/Specification for Windows, Doors and Skylights (Harmonized Standard), and
b) CSA A440S1, Canadian Supplement to AAMA/WDMA/CSA 101/I.S.2/A440, NAFS North American Fenestration Standard/Specification for Windows, Doors and Skylights .
They are also required as per article 184.108.40.206. to be installed in accordance with CAN/CSA-A440.4, Window, Door, and Skylight Installation.
There is also some additional Code information (don t want to list everything).
You might want to check with your supplier to see that the windows conform to these standards. You might also want to check with a reputable competitor for comment (All Weather is a supplier I use & know their windows are tested and meet Code requirements).
You might also want to check with your municipal building authority if you can find an inspector knowledgeable about windows. If they don t have all the information, they might let you know how you can contact the Provincial authorities who are true building scientists.
Sorry about the lengthy reply, very interesting and new problem.
This is not normal.
I remember my company installed a 10' x 8' door system in a enlarged opening make H the contractor. Once door system was installed in opening a few weeks went by when the customer heard cracking noises during daytime only when the Sun would beam onto the door. There was no fault in the door.
The noise after long investigation comes from insufficient support in the new opening. The contract later cut open drywall to add more vertical and horizontal support eliminating the cracking sounds.
My suggestion is to call back the company to add enough support to eliminate the noise.

Sorry a little further commentary after giving some more thought:
There is a very real likelihood that your windows and/or installation do not conform to minimum Code requirements. If that turns out to be true, you may be wondering how it's possible for a window manufacturer to produce a product in Canada that doesn't meet Code? They can do so for the export market & things like small sheds or farm accessory buildings that don't need to meet Code as an exception is given for them.
If they aren't compliant your next question may be: can the authorities make them fix (replace the windows with compliant ones) or shut them down? Unfortunately, you are named first off as the one responsible for Code compliance (the Owner). Manufacturers are prohibited by law to sell products for applications that they are not compliant for so certainly manufacturers & the installing contractor do have secondary responsibility.
If you try Googling CSA Product Listings you are led to the CSA website where you can select a category (windows) a country, and a manufacturer. If you try searching for All Weather, you will see that their windows have a product listing and you can read the test results. When I tried doing a search for your manufacturer there was no product listing found on the CSA website.
In Alberta if I have an unusual Code question that I (or anyone) want to get top level advice on the provincial authorities can be sent an email, and a response will never take longer than a day; not sure if it's the same in Ontario.
No this is not normal. Ive installed anderson windows before and never heard of this. It's a bad instalation or a bad build on anderson part. They should expand and contact so much they are making noise like that. I couldn't believe it when I watched the video
