'Quiet' Glass Improves Refinement For 2006 XJ

Silence is golden in a luxury car. That's why for 2006, Jaguar has added laminated, double-layer 'quiet' glass as standard to its entire XJ line-up.

The new side windows and windscreen feature two layers of laminated glass separated by an ultra-thin acoustic plastic interlaye, an interlayer coating and a second PVB interlayer. This acoustic sandwich reduces road and wind noise inside the cabin by an impressive five decibels - about the difference between being at a game with 5000 fans instead of 10,000.

The new laminated glass offers the added benefit of improved safety and security for those inside, by making 'smash and grab' thefts much more difficult.

That plastic interlayer between the glass will also reduce the effects of bleaching ultraviolet light which, over time, can deteriorate interior trim. Conventional green-tinted, toughened glass allows approximately 22% of UV to be transmitted to the interior, while the XJ's laminated glass allows less than 1% transmission.

And despite comprising not one, but two layers of glass, the 2006 XJ's new side windows are actually lighter than the previous singlepane windows, contributing to overall weight reduction.

"Refinement has always been a hallmark of the XJ. This is one more example of Jaguar making the XJ progressively better each year," says C.J. O'Donnell, executive vice president of Marketing and Sales for Jaguar North America.
