The Coating Process

Another patented feature of Conservaglass Plus™ is a special coating that makes it significantly easier to clean and maintain. This extra step during the glass manufacturing process bonds an exterior coating to the outer surface of the glass, making it super smooth to reduce accumulation of dirt and dust. This hydrophilic coating makes rain water "sheet off" rather than "bead up", which carries away dirt and dust, making the care of your glass so much easier. No competitor's glass has this technology.

Patented Technology that sets us apart from the competition
Four Seasons Conservaglass Plus™ is made differently than competitors' glass. Features such as bent corners, dual seal silicone and gas filling without fill holes make our Conservaglass Plus™ last about six times longer than the competitions'. Conservaglass Plus™ lasts from 30 to 60 years, the competition's only lasts from 5 to 20 years.

Insulating and Testing State-of-the-art robotic processing and testing ensure the highest quality, maximum performance and long-term durability.

How it works

Electrical energy is used to charge exotic compounds and metals which bombard the glass surface, depositing a micro-thin coating.

Eleven bombardment chambers are used with three targets in each chamber, offering 33 possible layering combinations.

Note: Because of new patent applications, exact layer specifications may vary.

Specialty Products

Curved Glass Manufacturing
The challenges of creating a Conservaglass Plus™ coating for curved glass were very formidable. Glass is normally coated prior to the tempering process. This, however, was impossible for curved glass. Therefore, a special coating process was developed to permit tempering and bending of the glass after the Conservaglass Plus™ coatings were applied. To do this, a state of the art bending process was developed.

High Impact Hurricane Glass
Four Seasons can provide Conservaglass Plus™ in heavy duty .090 laminated configuration designed to provide high impact protection from hurricanes as well as superior protection from vandalism or intruders. This heavy-duty glass is available for our entire structure, including the curved glass.

Meets Tough German and European Energy Codes
Determination of the areal thermal resistance and the areal thermal transmittance - (measurements on the glazing according to the German building products directive (Bauregelliste) Expert opinion concerning Test report No. 40119600/1 e of 24 November 1998. Determination of the total solar energy transmittance and the physical radiation data of glazing.

Tempered for Safety & Strength

Conservaglass Plus™ is four to six times stronger than ordinary glass and, if broken, would shatter into harmless, rounded pellets.

Meets or exceeds ANSI297.1 building codes for safety.

Lifetime Limited Product Warranty

And best of all, your Four Seasons Conservaglass Plus™ insulated glass panels come with a lifetime warranty.
