Triple glazing is standard in Northern Europe for its ability to block out unwanted noise and trap heat within your home. Whether that’s heat generated by your heating system or the sun, these thermally efficient windows will maximise energy efficiency by trapping and maintaining that heat within your home, keeping you warm and comfortable in the coldest weather.

Installing our high-quality triple glazing combines energy efficiency, savings on your heating bills and beauty in one innovative package.


When it comes to our triple glazing, we do not believe in having to sacrifice style for performance. Our windows and doors are available in a vast array of frames, materials, and finishes so that you can make your triple glazed products visually appealing.

In addition to the customisation options mentioned above, our triple glazed glass itself can be customised as well through the use of decorative glazing. As we manufacture all our own products, you will be able to design a style or pattern of bespoke decorative glazing.


Frequently Asked Questions

Does triple glazing make a difference?

Triple glazing is the best-performing glazing on the market. As a comparison, let’s look at the U-value of double glazed and triple glazed windows. The U-value measures the amount of heat lost, and the lower the value, the higher the level of insulation. 

Double glazing has a U-value of 1.2, while triple glazing has a value of just 0.6, meaning it performs twice as well as double glazing. This excellent performance means you’ll start to see savings on your energy bills.

How long does triple glazing last?

At Otter Windows, we supply all our triple glazed products with a ten-year manufacturer’s guarantee, but your windows are likely to last much longer. A lot depends on the installation, the weather, where you live in Honiton, Devon, or the surrounding area, and whether you keep your windows properly maintained. Our professional installers will be happy to give you tips on how to keep your windows in the best condition.

As a rule, triple glazing units will function well for 20 years and up to 35 years. It’s worth checking them regularly and keeping the frames clean to make sure they perform as they’re supposed to.

Is it worth replacing double glazing with triple glazing?

Triple glazing is a great investment to make and can add value to your property. Making the switch is not so straightforward if you live in an urban area or your double glazing is relatively new, as you may not see a quick return on your investment.

If you’re building a new home or you live in an area that experiences sharp temperature drops, however, triple glazing is definitely the right choice. As more heat is lost through windows than walls, triple glazing is also a good choice if your home has a large number of windows.
