Your Sunroom Glass’ Performance is the Foundation of Your Sunroom Satisfaction
Our Patented Glazing Keeps Four Seasons Sunrooms Warmer in Winter and Cooler in Summer
Four Seasons’ CONSERVAGLASS™ was designed specifically for the extreme demands of a room built entirely of glass utilizing the most advanced glazing technology available. CONSERVAGLASS™ makes Four Seasons room additions cooler in summer and warmer in winter, and its advanced construction techniques promise a lifetime of outstanding performance.
CONSERVAGLASS™ excels in all the categories important to you, including energy efficiency, safety and strength, and longevity.
Four Seasons Has the Highest R-Value in the Industry
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, a 4.0 R-Value is recommended. CONSERVAGLASS’ R-Value is 100% higher than our competition’s standard double-glazed glass, keeping your room warmer in winter.
Unsurpassed Visibility with Lower Reflectivity
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 your new room. A visible light transmittance below 60 is recommended for glare-free natural lighting. With a Visible Light Transmission of only 56, Four Seasons CONSERVAGLASS™ offers the perfect balance between visibility and glare reduction. No squinting or sunglasses needed.
CONSERVAGLASS™ 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 than the R-Value, particularly in summer and in warm, sunny climates. High Relative Heat Gain values indicate a room that will be unbearably hot or expensive to keep cool. CONSERVAGLASS™ Roof Glass’ Relative Heat Gain of only 39 ensures your room can be effectively cooled in all seasons.
The real story behind CONSERVAGLASS™ 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 roof, 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 four-seasons 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™.
Four Seasons sunrooms are backed by the Good Housekeeping seal.
