 Heat Mirror Reliability

Author: J.J.O. (---.proxy.aol.com)
Date:   

We looked at Newtown/Slocomb Heat Mirror window with fiberglass insulation, metal reinforcing interior bar below latch, a Heat Mirror and "Windjammer" parting bead. Has anyone had experience with the Heat Mirror as we are concerned with possible distortion of the Heat Mirror due to expansion and contraction from hot summers and cold winters? Has anyone had this window installed for at least one year?

If the "heat mirror" is the same as the low-emissivity coating used by the industry, you should get a long life. Some coatings can be damaged by moisture, so if a window seal is broken (for any reason) the "heat mirror" may be compromised. Condensation between glazings indicates a window failure.

Heat Mirror is not the same as low-emissivity costing used widely in the industry today. It is a coated film suspended between the two panes of glass in an insulated unit. Several different products are available - for example HM88, HM66, and I believe all the way down to HM22.
This is a product developed by Southwall Technologies that pre-dates the current low-emissivity costing available today.

We did use some of this (primarily HM88)several years ago, and did have some problems with film distortion and discoloration over time - particularly in back-yards near swimming pools. I would suspect that there have been product developments that have resulted in improvements since the time we used it, and owuld be interested in hearing other's experiences with the product.

I sold it back in the early 80's at it's inception and we had probems with it as well wrinkling and distorting years later. I don't personally recommend it nor will I sell a product with it, though I'm sure salesmen that do sell it would argue that it's great and that there are no problems with it anymore.
I'm just not one to give second chances once I've seen major problems with something. I owe my customers the benefit of my experience in carrying products I feel will last a lifetime for them.

I yield to the more informed sources. One manufactures windows & the other installs them. I fold.

We bought our Heat Mirror 9 windows 4 years ago. We have 40 windows, they range from Fix casements, Double Hungs, 2 Lite Tilt-N-Slide, and 3 lite Tilt-N-Slides, I have never had any problems. (We live near the water on a Lake.) I have only worked for Southern Vinyl Windows for 8 months now. I do believe that if the Manufacture does not have Qality Control in place anything is possible. (Not just in Windows) We have Customers that have had the Heat Mirror for over 10 years without any problems. I know that Heat Mirror has saved us enough in our Heating and Cooling bill to have paid for the cost of the Heat Mirror Option. Just my experience. Hope this helps. I have learned so much about windows myself in this disscusion board. Thanks
