Maintenance:

Windows that Virtually Clean Themselves?

The Science of CONSERVAGLASS SELECT™
The exterior coatings on CONSERVAGLASS SELECT™ are not magic, but they're close to it. A variety of different technologies go into manufacturing CONSERVAGLASS SELECT™, 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 sunroom and conservatory 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 minimum 4.0 R-Value. For extreme applications, CONSERVAGLASS SELECT™ has R-Values as high as 7.7 in our triple-glazed units and are 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 sun room that will be uncomfortably bright inside. You don't want to have to squint or wear sunglasses inside your new sun room, do you? A visible light transmittance below 60 is recommended for glare-free natural lighting. With a Visible Light Transmission as low as 13 , Four Seasons Sunrooms CONSERVAGLASS SELECT™ offers the perfect balance between visibility and glare reduction. No squinting or sunglasses needed.

CONSERVAGLASS SELECT™ 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 a glass room addition than the R-Value, particularly in summer and in warm, sunny climates. High Relative Heat Gain values indicate a sun room that will be unbearably hot or expensive to keep cool. CONSERVAGLASS SELECT™ Relative Heat Gain as low as 29 on some of our triple-glazed glass recipes ensures your sun room can be effectively cooled in all four seasons. Even our double-glazed roof glass has an outstanding Relative Heat Gain of only 39.

The real story behind CONSERVAGLASS SELECT™ 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 into the sun room, 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 - a true year-round sun room! Insist on a glass demonstration from any vendor trying to sell you a glass room addition. Four Seasons is confident you'll see the superiority of CONSERVAGLASS SELECT™.
