Our Operations Manager, Kirk, has taken a look at some of the most commonly asked questions from self-cleaning glass to different types of window frames. Below, we’ve outlined everything Kirk knows about window glazing and everything you need to know too.

window glazing

 

1. What is a U-value?

This is a very important aspect of window glazing as U-values measure the effectiveness of insulation. Double glazing and triple glazing usually have lower U-values because they don’t allow a lot of heat to pass through them; the higher the U-value, the worse the material is at insulating. When it comes to windows, both the frame and the glass are attributed with a U-value. Just remember, the lower the U-value, the more efficient the window.

2. Benefits of self-cleaning glass? And how does it work?

If you find difficulty in cleaning your windows or don’t want to fork out for a regular window cleaner, self-cleaning glass may be the way forward. The science behind it is particularly impressive, with two categories of coating: hydrophobic and hydrophilic. Both use water to clean the surface, one by creating droplets via different surfaces, such as polymers and waxes, and the other by utilising rainwater as a ‘sheet’, removing any dirt without any smears or streaks. The most popular use for self-cleaning windows is hydrophilic as it’s much more cost effective and work wells on materials such as glass.

3. What are the different types of window frames? And which is the best one?

Only 43% of homes in England are fully double glazed, so it’s no wonder that there are so many different types of window frames to choose from to fit all property and glazing types.

– Aluminium

As mentioned before, U-values are important when looking at efficiently for windows, both the glass and the frames. However, aluminium is a very strong conductor of heat, so measures need to be put in place to ensure this robust and light material can insulate more effectively.

– Wooden

Wooden frames can be aesthetically pleasing, especially on period properties. They’re also a fairly good insulator, but come with a few disadvantages, such as regular maintenance to keep them looking new. They also expand / contract dependent on the weather conditions, which can warp and twist the wood.

– Composite

Similar, but much more effective than just wooden frames, composite frames contain wood products, combined with another material, such as aluminium. This gives the effect of an appealing wooden finish on the inside, with the strength of aluminium on the outside. They’re both energy efficient and a great insulator.

– uPVC / vinyl

Each come with their own unique advantages and disadvantages, but for double glazing, uPVC / vinyl frames are usually the most popular and the most efficient. The material is easy to maintain, can be wiped down without effort, and is resistant to pollution. Windows that utilise uPVC are usually strong and robust too, so will last a while.

4. Benefits of heat absorbing tints?

Most commonly used in commercial buildings, tinted glass or glazing absorbs the sun’s powerful solar heat. This high-performance glass blocks daylight into a building, as well as increasing privacy.

5. What are the different types of window coatings?

If you’re looking to reduce your energy loss, window coatings, such as low emissivity coatings, can aid this. If you already have double glazed windows, you can buy films to apply yourself, but the majority are applied to the glass during the manufacturing stage. Coatings generally reflect, therefore reducing solar radiation.

6. Can I repair any failed double glazing?

Yes, you can. Contact your local branch of Cloudy2Clear today for a free, no obligation quotation. We can assess your windows and the type of glass / frames you have and offer expert advice of the best next steps.
