Maintenance:
Windows that Virtually Clean Themselves?
The Science of CONSERVAGLASS PLUS™
The exterior coatings on CONSERVAGLASS PLUS™ are not magic, but they're close to it. A variety of different technologies go into manufacturing CONSERVAGLASS PLUS™, but the key technology that helps the glass stay cleaner longer is the super-thin coatings we apply. Using a patented coating process, invisible, durable and permanent coatings of both silicon dioxide and titanium dioxide are applied to the outside of the glass, permanently enabling your window and door glass to stay cleaner longer.
Energy Efficiency:
Outstanding R-Value
R-Value
R-Value measures how easily heat travels through a material, or its thermal Resistance. The higher the R-Value, the greater the insulating effectiveness, the lower your energy costs and the greater your comfort. For maximum comfort, Four Seasons recommends a 4.0 R-Value. CONSERVAGLASS PLUS' R-Value is 100% higher than our competition's standard double-glazed glass, keeping your room warmer in winter.
Unsurpassed Visibility with Lower Reflectivity
Light Transmission/Glare
The percentage of visible light transmitted through the glass. High numbers here indicate a room that will be uncomfortably bright inside. You don't want to have to squint or wear sunglasses inside, do you? A visible light transmittance below 60 is recommended for glare-free natural lighting. With a Visible Light Transmission of only 56, Four Seasons CONSERVAGLASS PLUS™ offers the perfect balance between visibility and glare reduction. No squinting or sunglasses needed.
CONSERVAGLASS PLUS™ Blocks 85% of the Sun's Solar Heat!
Relative Heat Gain
Relative Heat Gain measures the heat gained through a glazing. This number is more important in in warm climates than the R-Value. High Relative Heat Gain values indicate a window tath will let in a lot of heat and will make it expensive to keep cool.
The real story behind CONSERVAGLASS PLUS™ and what makes it so special is its exclusive, patented, multi-coating. This extraordinary process uses multiple microscopic coatings of exotic metals and compounds to let beneficial natural light, while keeping out the oppressive summer heat and damaging UV rays. This remarkable glass also reflects interior heated air back into the room, keeping you warmer in winter as well. Insist on a glass demonstration from any vendor trying to sell you windows and doors. Four Seasons is confident you'll see the superiority of CONSERVAGLASS PLUS™.
Less energy used to heat and cool = good for the planet
