How to Make a Glass Unit

Glass Unit Manufacturing

For our second blog we have chosen the process of creating an A-Rated Unit.

Many people claim to know what an A-Rated unit is and the benefits it holds in comparison to a single glazed unit. However, upon receiving inquiries for either windows or doors the customer becomes interested in more "technical" information regarding what exactly is used in the manufacturing process.

To answer this question we have created this post to guide you through the process involved in creating our A-Rated Unit.

The process involves;

• Glass Cutting (Cut to the specified measurements, we use Low-E glass to ensure minimal heat loss)
• Cleaning of Glass
• Checking of Energy Rating (This is to ensure that the quality of glass we use matches our Expectations and Quality Standards)
• Warm-Edge Spacer Bar (This bar is used to separate the two glass units, the bar is then filled with a molecular sieve window absorbent called desiccant, this desiccant is used to absorb liquid that may come into contact with the glass unit itself. Desiccant can absorb up to 22% of its own weight allowing you to sleep easy knowing your glass units will be there for a Long time before any breakdown occurs.
• Sealing the Units (The sheets of glass with spacer bar are then sealed with a sealant called Isomelt. This seal adds stability to the Double/Triple glazed unit and heat insulates the glass unit.
• Argon Gas: The gas is then injected into the glass unit, the gas fills up the area of space between the two glass cuts. The air pocket is filled with this gas and then the unit is given one last seal to cover the area where the Argon Gas was inserted. 

The Glass Unit is now ready to be inserted into one of our uPVC Windows or Doors
