Exclusive CONSERVAGLASS SELECT™
Only the highest quality materials are used. Our exclusive, insulated, CONSERVAGLASS SELECT™ is so durable, we provide a lifetime limited warranty. It has continuously achieved a CBA rating (the highest available), by certified independent testing laboratories.

ISO 9001 Designation
The exclusive and proprietary CONSERVAGLASS SELECT™ coating is produced under the ISO 9001 designation from the International Organization of Standards. In addition, every glass item we manufacture uses tempered safety glass meeting SGCC as well as German DIN Ratings. These features provide exceptional durability and safety for your sunroom.

Frame and Hardware
Four Seasons asks you to compare the quality of our aluminum extrusions with the competition. Four Seasons uses .060 - .080 gauge walls while others use .045 thickness walls (ours are 33% - 77% heavier).

Our marine grade stainless steel fasteners, neoprene gaskets, hardware and lock sets are of “superior” quality. This results in a product that will stand up to the heavy use that an active family or commercial environment demands.

Durability
Dual seal silicone sealant and non-broken bent corners provide a panel that resists seal failure and sloped glazing stress factors up to eight times better than alternative edge seal constructions.

Edge Sealant Durability
CONSERVAGLASS SELECT™ is made using a “dual seal”. We begin with a primary seal to minimize moisture transmission, and a specially formulated silicone second seal to provide long-term adhesion. Since silicon isn't damaged by UV (as are other sealants), there is total UV protection along with extremely long life span.

Exceeds Building Code
The engineering and construction integrity of our products far exceeds building code requirements. In fact, unlike other manufacturers, we evaluate all structural connections for load bearing ability, not just the support beams. This results in a product that will withstand decades of use with little or no maintenance or repair.

Overall Product Performance
Product performance is an area on which Four Seasons places major emphasis. Problems that others have, such as summer heat gain, winter heat loss, air infiltration, condensation, glass durability, window and door operation and sheen of paint finish are areas where the quality of Four Seasons products prove their worth. The superior performance of Four Seasons products means years of enjoyment and satisfaction for you!
