Quad LoĒ-452+^™ Premium Glass: A Decade in the Making.

New Quad 452+ is a true four-layer silver coating with exceptionally low emissivity, 99% UV protection, low exterior reflection and superior solar control. It also comes standard with Neat+™ — an exterior coating that stays cleaner longer and is easy on the environment.

Superior performance. Naturally cleaner glass. This is a breakthrough combination that you won’t find anywhere else.

A new standard in performance.

Quad 452+ has an SHGC (solar heat gain coefficient) of 0.22, a visible transmittance of 52%, and an excellent 2.30 light-to-solar-gain ratio. It also has a low exterior reflection (10%) and is neutral in transmission, in reflection, and on angle.

The end result is superior solar control and the lowest emissivity within the Cardinal family of LoĒ coatings. All of which translates to excellent energy-efficient performance.

More comfort than ever.

In hot, sunny climates, Quad 452+ clearly outshines ordinary window glass. It is formulated specifically to manage solar heat gain while maintaining clear views, taking more of the burden off the AC unit to keep conditions comfortable inside. The low emissivity of Quad 452+ glass also means warmer rooms during winter.

Fade perception.

Uncoated glass allows more UV light to reach the interior, which can damage furniture, carpets and artwork.

Exceptional fade protection.

QUAD 452+ blocks 99% of UV rays to protect furnishings.

Neat+ coating: standard on all Quad 452+ glass.

Standard on all Quad 452+ glass and featuring 25% higher photocatalytic activity than original Neat®, Neat+ repels 40% more dust and dirt than uncoated glass.

Neat+ incorporates titanium dioxide that reacts with the sun’s UV rays to also break down greenhouse gases such as methane to further clean the window. This saves homeowners time while requiring less water and chemicals, helping to reduce environmental impact. With sufficient UV radiation, water will sheet away, improving drying time.

Keeping it neutral.

In addition to its performance advantages, the fourth layer of silver in Quad 452+ glass enhances the grey to aid in a neutral appearance. This provides architects and designers with greater flexibility to specify the glass for a broader palette of building façade colors.

Add LoĒ-i89 to trap the heat indoors during cold weather.

For climates that get cold in winter as well as hot in the summer, insulating glass units (IGUs) with Quad 452+ glass can be specified with the optional LoĒ-i89 coating. Indium tin oxide is sputtered onto the interior side of the glass panel to reflect escaping heat back into the room, lowering U-Factor.

Combined with exceptional solar control and naturally cleaner glass, these three coatings in a dual-pane IGU deliver everything you want in a window.
