The cost of triple glazing can be offset with the savings you’ll make on energy bills each month. Studies have shown that windows can let out up to 20% of the heat in your home. That means your heating needs to work harder to maintain a steady temperature.

Older double glazed windows and doors, as well as single glazed fittings, are notorious for being extremely inefficient at insulating. Triple glazing, on the other hand, can effectively seal the heat inside.

This keeps your home at comfortable temperatures more efficiently and for longer. It’s also quite effective at keeping unwanted noise out, so the initial triple glazed windows cost is a worthwhile investment for your home.

How Does Triple Glazing Compare With Double Glazing?

The difference between double and triple glazing is more than just an additional pane of glass – there’s improved performance and noise reduction to consider, too. The cost of triple glazed windows and doors can be significant, however, so it might not be something you want to do unless you have single glazed glass or old double glazing that isn’t working as well as it should.

You will notice a change in the temperature almost immediately with triple glazing. Windows with high Window Energy Ratings provide better cost savings than other glazing options, but this is dependent on the energy ratings you get.

How Much Does Triple Glazing Cost Compared To Double Glazing?

The cost of triple glazing is almost 30% higher than double glazing, on average. Depending on the size of your windows, and if you’re changing the style or design, this could increase. You’ll also need to keep in mind that installation costs are not usually included in this figure, which is something else to budget for.

Are Triple Glazed Window Costs Worth It?

Whether the cost of triple glazing is worth it depends on your current situation.

You’ll want to know if the savings you’ll make from installing triple glazing will outweigh the cost overall. If you’re replacing single glazed glass, or old double glazed glass, you will see improvements in the thermal efficiency of your home, allowing you to reduce how much you spend on energy each month.

The noise reduction will also help if you can hear a lot of external sounds, whether a busy road is nearby or something else you can hear consistently. There is also the improved security aspect – you can’t underestimate what this peace of mind brings.

If you have more recent double glazed windows, then the performance improvements will be minimal, and there might be other things you can do instead. Heavy curtains, for example, can provide an extra layer of insulation over your double glazing. They are more cost-effective than triple glazed windows, and they will help insulate your home without any extra energy required.

Another alternative to triple glazing is secondary glazing. Secondary glazing is a single glazed pane and frame that you can fit over your double glazing. You get the extra layer of insulation that acts just like the third pane in triple glazed windows, which will also reduce energy costs.
