 Re: Heat Mirror Reliability

Author: Cheryl (63.194.168.---)

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.
