How Thick Is Window Pane Glass

The whole idea behind getting double glazed windows is to better insulate your dwelling house with a drinking glass unit that is thicker and performs better than a single glazed window.

But, exactly how thick is double glazed glass?

What role does glass thickness play in window operation and free energy efficiency?

Double Glazing Thickness in Millimetres

With double glazing, a professional will install an insulated glass unit (IGU) into the window frame. An IGU consists of two panes of glass and a layer of still air or inert gas in betwixt.

So, the full double glazing thickness in millimetres (mm) encompasses the thickness of each pane of glass and the thickness of the gap in betwixt.

Both the added thermal resistance you become from two panes of glass instead of i and the insulation effect of the airspace – which slows down the movement of thermal free energy thus reducing heat loss – are what create the benefits of double glazing and lower your heating and cooling costs.

And, the thicker each of these elements are, the amend performance y'all'll go out of your windows.

How thick are the two glass panes of a double glazing unit of measurement?

A typical glass pane is 4mm thick.

Two panes of drinking glass would and so add together 8mm to your double glazing unit of measurement thickness.

You can also utilise thicker drinking glass, which can accomplish slightly better thermal insulation benefits and aaasignificantly improved acoustic benefits.

It's possible to use two different drinking glass thicknesses in 1 IGU, such as 6mm for the inner pane aaaand 10mm for the outer pane. In fact, using varying thickness can exist effective for blocking low aaafrequencies of sound, like traffic noise.

How thick is the gap in a double glazing unit?

The infinite in betwixt will usually range from 6mm to 20mm.

For greater energy efficiency, 10 to 20mm is a proficient idea, with at least 12mm being effective for aaaboth thermal and acoustic insulation concerns.

In situations where a bigger air gap is non able to be used due to frame thickness restrictions aaathis is where a high performance Depression E Glass and Argon Gas installed inside the IGU will pick up aaathe performance of a thinner IGU helping information technology perform similar a thicker air space.

Is Your Double Glazing Thick Plenty to Work?

Even a double glazing unit with standard glass and air gap thicknesses will make a divergence in your dwelling unless your unit has failed. If the seal on the IGU has broken, rut will exist able to escape.

How to check if your double glazing is working?

If you have whatever condensation on the inner surfaces of your glass – the ones facing the air gap – yous accept a problem. Fog on the glass is a tell-tale sign that the IGU has become damaged and your double glazing unit isn't serving its purpose.

What can you exercise – what about resealing double glazing?

When the sealing in the IGU is damaged, unfortunately, yous can't just go in and reseal the unit. The merely solution is to supervene upon the double glazing. If your windows are even so under warranty, y'all tin have your original installers replace the units for you.

The seal on double glazed windows is vulnerable to damage over time as some moisture will eventually go into the unit of measurement and damage the seal, peculiarly in timber windows with a square rebate where h2o can sit.

At Thermawood , we designed a unique dry out Retrofit Double Glazing system to prevent these issues. Each window has a patented drainage organization, which sits on a xv-degree slope in the window rebate and gets rid of any h2o before it becomes an outcome.

That way, you can get the ideal double glazing units for your habitation in terms of glass, operation factors, and relish your double glazed window benefits for decades.
