Modern insulated glass units are “dual seal” technology with a primary PIB seal and a secondary backfill of urethane or silicone. These units last far longer than the old technology. It used to be that all warranties were void if you lived within a mile of the water – now we can offer a silicone sealed unit that is warrantied for 10 years even if you live right on the ocean!

Although when doing so, you need to change all the window glass on the same side of the house at the same time because the low-e glass looks differently. It will appear slightly blue-green in its reflection. If you change one window to low-e and have a regular glass next to it, it will not look right. Low-e glass will help with both heating and cooling expenses.

Any defects or failures in the first year are 100% covered with materials and also labor.  All of our insulated glass units are warranted for 10 years.   Our warranty is pro-rated and only covers the glass and not the labor to install it. Exceptions to the warranty are: units that are 3/8″ thick overall (most units are rarely this thin) and units installed in a chlorinated pool area. This Warranty is in lieu of all other warranties, expressed or implied, including but not limited to any implied warranties of merchantability or fitness for a particular purpose. The remedies set forth in this Warranty shall be the exclusive remedies available to any person. Cape & Islands Glass, Inc. shall under no circumstances be liable to any person for incidental or consequential damages of any description. No person has any authority to alter this warranty. Most insulated window glass is not tempered and is custom ordered to your exact specifications. These units usually take 10 business days to be manufactured. Tempered insulated glass is required for doors, next to doors or within 18″ of the floor and may take a few more days to produce.
