When Should I Change My Thermal Windows?

The life expectancy of thermal windows can depend upon a number of factors, including the type of thermal pane used and the manufacturer. Most thermal windows can be expected to last for about 10 years with proper maintenance. If you notice condensation forming between your thermal windows, it is time for replacement.

What Is The Benefit Of Low E Glass?

Low emissivity glass (Low E) employs thin transparent layers of metal oxide that are applied to the surface of the glass. Low E glass enhances energy performance in warmer climates by filtering unwanted heat and UV rays and preventing them from entering your home. Likewise, in colder climates the Low E coating allows UV rays to pass through the glass and retains interior heat to help warm indoor temperatures. Although energy-efficient Low E replacement windows cost more initially than traditional windows, the energy savings throughout their lifetime allow you to recoup your investment and enjoy additional savings.

How Do Insulated Windows Work?

Insulated glass windows consist of 2 panes of glass separated by a space. Windows represent thermal “holes” through which the average home can lose as much as 30% of its heating or cooling energy. All glass panelled windows gain and lose heat through convection, conduction and seepage. Energy efficient insulated windows employ transparent metallic coatings, multiple glass panes and/or gas fillers to provide a physical barrier to these heat-robbing processes, keeping warm air inside during the winter months and outside during the summer.

What Is The Warranty On Thermal Windows?

At Oomen’s Glass Ltd. we install and recommend Ostaco windows. All Ostaco windows come with a limited lifetime warranty on all parts, vinyl and insulated glass. Our thermal windows carry a 10-year warranty.

What Is The Standard Thickness For A Glass Tabletop?

Glass that is ¼” thick is sufficient to protect a tabletop from scratches and stains.

What Is Tempered Glass?

Tempered glass is a type of safety glass that is 4 to 5 times stronger than standard glass and does not break into sharp shards when it shatters. Instead it breaks into small, oval-shaped pebbles with no sharp edges. For this reason and because of its superior strength tempered glass is often referred to as safety glass.

Can You Cut Tempered Glass?

Tempered glass is heat-treated to provide strength, durability and resistance to heat. Once glass has been tempered in this manner it is no longer possible to cut it to shape without shattering it. Tempered glass should be purchased in a precut form, or if this is not possible, un-tempered glass can be purchased, cut to the required dimensions, and then tempered.
