Zen Windows By Soft-Lite

Zen Windows are manufactured by Soft-Lite Windows, which is a well respected vinyl window manufacturer that is headquartered in Streetsboro Ohio. They have branches in Cleveland, Cincinnati, Columbus, Philadelphia, Washington D.C., Chattahoochee Valley (serving Georgia and Alabama), Denver, Houston and Austin. There are a number of additional locations, these are just the ones we could track down.

Zen windows offer three window series, the Karma, Nirvana, and Lotus. Essentially, the Karma is the entry level window and is the Soft-Lite Barrington, the Nirvana is the mid range window and is the the Soft-Lite Classic, and the Lotus is the "premium" window and is the Soft-Lite Pro. I put parentheses around premium because the Soft-Lite Pro is a good window (but not great), but I would have liked to see the Imperial LS or the Elements used as the premium model. Personally, I would stay away from the Karma, but the Nirvana and Lotus are very nice windows - check out the individual pages to see more detailed information.

One word on franchises - they tend to be a mixed bag; one franchise might offer excellent prices and fantastic installation, while another might charge overinflated prices and offer mediocre installation. It's incumbent on the consumer to do their homework, read reviews on the franchise in your area in order to make sure you are getting a fair price and excellent installation. This is one of the principal reasons we always suggest getting a least three bids - you can compare apples to apples on the exact same project.

Zen Windows Warranty

The company offers a limited lifetime warranty that states that their windows and patio doors are free from workmanship and material defects. PVC coatings, hardware, internal mini-blinds, and leaded glass carry a 10 year warranty provision.

The warranty also includes a glass breakage provision, although it is unclear whether this is an optional upgrade (it typically is with the lower end Soft-Lite windows.) The warranty includes a labor provision that covers the cost of removing and replacing the Zen windows in case of a warranty claim.

St. Louis, Missouri Window Recomendations

Hi, I am looking to replace 11 double hung windows in my home located in St. Louis, MO next year to vinyl windows. I have no idea where to begin looking for windows to get quotes. In searching the web, I saw featured Windows Nation, Window Depo, Zen Windows, Universal Direct Windows, Window World etc. I do not want to waste my time in gathering quotes especially with Pella, Anderson, Marvin due to their higher prices.

My top budget spend for window & install is around $600-$700 dollars.

Your help is greatly appreciated. Thanks for your time, consideration & reply.

John, here is my list of good and great windows. From your list, I would look at Zen (they sell the Soft-Lite Classic and Pro), and Universal Direct (they sell the Unishield made by Polaris).

Zen Windows Costs

I just received a bid for infinity by marvin ultrex windows in Denver, CO for $18,000 to replace 15 old 1954 windows. This totals 222 square feet argon filled dual pane windows, LoE3-366 rating. Would be very happy to hear your opinion on the price and quality of these windows. I would be happy to write up a review on your site for your assistance. If you could help me with this I would greatly appreciate it. As it is the end of the month I'd like to get back to the salesman by late tomorrow, apologies if this is an unrealistic turn-around time.

Andrew, the Marvin Ultrex is an excellent fiberglass window and one that should serve you well with proper installation. As far as price, this seems in line generally, although its nearly impossible for me to make this judgement since I don't know the project specifics. I would highly recommend that you get several more quotes to compare price and companies. I know that Zen Windows has a branch in Denver (they sell Soft-Lite vinyl windows), I think they sell three models and the top two are good, avoid the entry level option.

Also check on Alpen Windows, which are expensive, but very well made fiberglass windows. Milgard also makes a good fiberglass window, the Ultra model, which might be a good comparison window as well.

I'd caution to take your time and get the bids and spend a bit of time doing some good comparisons before pulling the trigger.
