Warmer in Winter and Cooler in Summer

Four Seasons Sunrooms' CONSERVAGLASS SELECT™ with Stay-Clean Technology was designed specifically for the extreme demands of a room built entirely of glass utilizing the most advanced glazing technology available. CONSERVAGLASS SELECT™ helps make Four Seasons room additions cooler in summer and warmer in winter, and its advanced construction techniques promise a lifetime of outstanding performance.

CONSERVAGLASS SELECT™ with Stay-Clean Technology excels in all the categories important to you, including maintenance, energy efficiency, safety and strength, and longevity.



Windows that Virtually Clean Themselves?


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 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™.

All of our sunroom plans begin with our amazing, patented CONSERVAGLASS SELECT. With CONSERVAGLASS SELECT, every glass room is truly a four-season sunroom to be enjoyed winter, spring, summer and fall. The performance of Four Seasons' CONSERVAGLASS SELECT is protected by the use of state-of-the-art materials and construction techniques. To ensure your security and peace of mind, CONSERVAGLASS SELECT excels in all the categories important to you. CONSERVAGLASS SELECT gives your glass patio room the strength, safety and longevity you’ll appreciate for a lifetime.

Here's how it works:

Strength and Safety

A Tempered Glass Room For Your Peace of Mind

Safety is the paramount consideration in all of our four-season sunroom plans. CONSERVAGLASS SELECT is made with tempered safety glass which is four times stronger than regular window glass. CONSERVAGLASS SELECT ensures the strength, safety and security of your glass room.

Longevity and Energy Efficiency

Stainless Steel High-Tech Glass Spacers Ensure Trouble-Free Performance

Many insulated glass room manufacturers use inexpensive, conductive aluminum as their standard spacer material between the lites of glass. Insulated glass that uses this type of spacer can be cold and prone to condensation. We use a much stronger and thermally stable Stainless Steel edge spacer for the enduring strength of the glass room addition and your comfort and safety. Then, to maximize its benefits, Four Seasons bends the stainless steel into a continuous, extra-strong frame rather than using failure-prone corner keys like other glass room addition manufacturers.

Dual Seal Silicone for Double Protection

PIB + Silicone = Extra Long Life

For your protection and to ensure years of trouble-free performance, Four Seasons glass room additions use not one, but two, seal systems to create its insulated glass unit. The glass and stainless steel spacers are bonded first with Polyisobutylene (PIB) as the primary seal and then, for added protection, a second layer of silicone for strength

Energy Efficient Sunroom Construction

Superior Thermal Performance For Your Glass Room Addition
We use CONSERVAGLASS SELECT in all of our four-season sunroom plans. CONSERVAGLASS SELECT is an essential component of our sunroom plans because it is designed and constructed as a super energy-efficient product from the ground up. To ensure trouble-free energy efficiency for a lifetime, CONSERVAGLASS SELECT does not use leak-prone injection holes like other glass room addition manufacturers, but is assembled in a "clean room" - ensuring no holes to leak.

All this advanced technology creates Four Seasons Sunrooms CONSERVAGLASS SELECT with Stay-Clean Technology, a product built to last a lifetime and backed with a warranty to match.
