Inline Fiberglass Ltd

I ordered 21 windows and 2 patio doors from this company. Spent over $30,000 with expectations that this company's windows would make my home warmer by not allowing as much air to pass through compared to 25 year old existing windows (old windows were wood inside and PVC outside). I was told:

- frame and glass of window are both made of fiberglass so they will expand and contract equally not causing seal breaks or warps like wood and PVC...they told me this on a factory tour, saying that glass expands/contracts differently from other materials
- fiberglass does not transfer heat or cold like aluminum or steel frames

The windows look gorgeous but the quality of the glass and frame are not on par. The fiberglass frame has very poor insulation inside, not even filling the entire cavity so lots of cold air sits in there from the outside...look at my thermal imaging photos. It's extremely cold to the touch from inside. See my photos...these frames are very poor quality and will run below 5 degrees in the winter. I was told that the cold draft was the result of normal air flowing downward from the glass.

The glass is also of poor quality.... I ordered double pane windows and even triple pane in some rooms and the heat loss is worse than my 25 year old windows. There are drafts that come in through these windows and into the home, it's a major problem when combined with the very poor frames that they use.

I contacted customer service and they replaced one window but still same issue...that's when I saw how cheap the insulation they use is. It's literally an empty frame with some foam insulation and they added a "backer rod" which is a rubberized looking thin roll to help block the draft from outside.

I've had to spend more money to get indoor window inserts from a different company to stop these crazy drafts. The patio doors are even worse...I had to install heated floors to stop them from letting frost in (inside the home)! Again see photos for reference, you can't make this stuff up.

Worse part is, I contacted Inline again to see if I could pay to upgrade the glass to triple pane and was told by my rep it won't make a difference from what I have. I would normally double check this but I believe him since one room in my home already has triple pane windows and we hear dogs barking through it easily with the same cold draft as the double pane windows...

I do not recommend these windows because they allow noise and drafts to pass through very easily.

I did a major renovation and addition 12 years ago and replaced all the existing windows plus added some new windows for the addition. There was nothing wrong with the existing windows but they were 20 years old and I wanted all the windows to match. I was assured the Inline windows would be superior than the ones I was replacing so I assumed they should be trouble free for at least as long as the existing windows. I recently had a seal fail with moisture between the glass. I contacted Inline and was told my windows are not under warranty and the cost to repair the window would be over 2,100.00. I never had a seal fail on the old windows which were cheaper than the Inline windows. This window failed after only 12 years and now I am concerned about how long the rest will last. It appears as though these windows weren't worth the extra cost.

The windows are great. What an improvement over the old vinyl windows. The installation guys are even better. They took the time and installed them right. You would never know the windows were replaced.

We recently purchased windows and sliding door from Inline Fiberglass company. We are grateful for this decision as the quality engineering, glass type and hardware used to manufacture these is the best in all aspects. We were thrilled to see the sliding door with height and width over 10 feet produced and delivered as one piece. I was deeply touched by the company culture of integrity and respect. Amazing leadership at all levels towards customer satisfaction!

Upgraded from PVC to fiberglass. The quality of the windows is superior to any other windows that I've come across while shopping around. I'd definitely choose Inline again because I'm very happy with the product.

The design and quality of the product is matched by the impeccable service.
We were interested in replacing all 19 windows along with the patio sliding door in our house. The quality, size, and aesthetics of the fiberglass options from Inline Fiberglass really stood out to us compared to alternatives such as vinyl. We figured the cost is offset by the better insulation and increased house value. However, we are very picky shoppers, so it is nice to be able to say that Inline Fiberglass exceeded our expectations.
The sales team helped us select the designs and colors that best complimented our house. The installation was impeccable, our furniture was protected and there was not a single scratch out of place. And the end product couldn’t be more impressive. The immediate compliments from neighbors and visitors aside, there is something to be said about the quality of the product when you're just as drawn to looking at the window as you are to looking through the window at the outside world.
Highly recommended.

Replaced all the windows in the house and even added a sliding door to a newly built sun-room. The quality of Inline's windows is exceptional. The installation went smoothly and I'm very pleased with the windows. As such, I highly recommend Inline, they're local and have excellent service.

Unbelievable service from start to finish. We were given different options for us to choose. They were able to customize our order to make it work out the way we envisioned it. The finished product was better than we expected. We’ve had several great comments about it. I would highly recommend Inline Fiberglass to anyone looking to replace their windows and doors.

Extremely satisfied from the initial call to the delivery of the product. Great customer service, product knowledge, production was right on time and delivered, as promised. They made the process smooth and easy. Highly recommended.

Great company! Amazing/superior product! The best customer service I have experienced in a window company!!! I would highly recommend this prouduct to anyone and everyone. My family and I couldn’t be happier about our windows!
