How Does Double Glazing Work?

There are countless benefits of double glazing your home, it reduces noise, keeps your home warmer, lowers power bills, increases the value of your home and more. But how does double glazing actually work? Read on and find out the ins and outs of how it works and how it offers these benefits.

What is double glazing?

Double glazing is a window that has two panes of glass, making it double glazed. The two sheets of glass are separated which creates an air gap which is then filled with an insulating gas. You could think of it as a glass sandwich and the filling is gas. The main benefit of double glazing is insulation, it retains heat in a room while stopping cold air entering from the outside, which makes the room more energy efficient.

What are they made from?

1. Two panes of glass for windows or doors

2. A thermal spacer separates the glass

3. Argon gas that fills the space

Is there anything special about the glass?

Ryan Double Glazing uses high spec glass units which are made up of high-performance low emissivity (LowE) glass. LowE glass refers to the surface condition that emits low levels of radiant thermal heat energy. It has a fine, transparent coating that reflects long-wave infrared energy which helps combat heat absorption in summer, heat loss in winter, condensation, UV radiation and glare.

How does argon gas work?

Argon gas is an inert gas which means that it does not undergo chemical reactions under a set of given conditions and is not harmful to us or our pets. It’s denser than air acting as a greater barrier to heat loss and heat absorption in the home. Thermal spaces break the thermal bridge from outside to the inside of the unit, at the glass edge. This creates a warm edge giving a better overall performance.

How does it reduce heat loss?

1. Cold air cools the outer pane of the glass the cold is transferred to the air gaps between panes

2. Argon gas slows down the thermal transfer

3. The cold air doesn’t reach the inner pane

4. The warm air also meets the inner pane is also slowed down by thermal transfers so heat is retained in the room
