How to take care of triple glazing to ensure longevity

Once your triple glazing has been installed, proper maintenance will ensure that you have beautiful and efficient window and glass doors for many years to come. Here are a few tips on how to take care of your triple glazing to ensure longevity.

Your installer will explain any specific instruction with regards to the maintenance of your windows and will give your new glazing a good cleaning after installation. If you become aware of anything stuck between the glass panels in the first few weeks after installation, alert your installer immediately.

Cleaning the Interior Glass


Generally speaking, triple glazing is cleaned like any other glass.

First remove any dust from the frame and sill with a soft brush or by vacuuming, taking care not to damage the paint work or frame finish. Next, wash the window with mild soapy water and a sponge or soft cloth, or use a specialized spray-on glass cleaner. Take care not to use an abrasive cleaner that may damage the glass and the frame. Adding a dash of vinegar or lemon juice to the rinsing water will give some extra sparkle to your windows. Remove any excess liquid with a squeegee and buff with crumpled newspaper.

PRO TIP: wash your windows on a cloudy day to prevent the water from drying too quickly and streaking the windows.

There really aren’t any rules when it comes to the frequency of cleaning your windows, but washing them every few months will make a big difference to the amount of light that comes into your home.

Cleaning the Exterior Glass

The exterior glass can be cleaned in the same way as the interior, although many manufacturers also offer self-cleaning glass. This type of glass is coated with a thin film that breaks down organic dirt with the help of UV light, and that is then washed away by rain water.

If your windows are very difficult to clean or hard to reach, contact the Federation of Window Cleaners for a professional cleaning quote.

Window Damage

Because triple glazing is a very specialized product, and because of the gas contained in the sealed unit, it is not advisable to repair cracked, broken or damaged glazing yourself but to rather get an expert to do it for you.

1. Cracked Glass


A crack in your triple glazing will mean that some of the gas in the gaps between the glass will start to escape, which in turn will reduce the efficiency of your window. Cracked glass also poses a health risk because the panel’s strength has been compromised, so it advisable to have it dealt with promptly.

There are generally 3 types of cracks in triple glazing.

1) Thermal stress crack
This type of crack is caused because of thermal variance. The central glass panel of your triple glazing is made with tempered glass and this type if crack is very uncommon.

2) Impact
A ball or rock can do some serious damage to your glazing.

3) Edge damage
Especially in tempered glass, damage to the edge of the glass can cause the glass to crack from the outside towards the center of the panel.

2. Breakage


As with a cracked unit, broken glass will reduce the efficiency of the window significantly and pose a health risk, so it’s best to have it dealt with when it happens.

3. Gas leak


A gas leak appears as a misting up of the interior of the sealed unit. This can be caused by the age of the unit, a faulty seal or damage to the glass. Because the low heat conductivity of the gas assists with the efficiency of the unit as a whole, the leaking of gas will increase the heat lost to the outside of the window. This may then also increase risk of condensation on the interior of the window.

Frame maintenance


PVC and aluminium frames are very easy to maintain and generally only require a wipe down to remove dust. Take care not to get any glass cleaning products on the frame which may cause damage to the surface finish.

Wooden frames require more maintenance to ensure their longevity – they have to be sanded and resealed every 3 to 5 years to prevent moisture from causing damage to the wood. When the wood has a scratch or chip that is not taken care of immediately, it may render the window warrantee invalid so it’s best to repair of any damage as soon as you become aware of it.

Hinges and Handles


To ensure the proper functioning of your triple glazing window, check all the handles and hinges annually and oil or repair them where necessary.
