Double glazing windows and doors Glass design

On Southall Windows double glazing blog we have talked about many types of glass used in the double glazing industry.

These glasses are standard glass, toughened glass, tempered, reflective glass and acoustic glass.

Some people want their house more decorative by installing double glazing windows and doors with decorations on it.

The decoration is mainly in between the double-glazed glass.

Here are some of the examples of installation done by Southall Windows.

Glass-design-Richmond-double glazing

We manufacture a variety of glass with different decorative patterns, texture, colour and opacity. Decorative glass in double glazing windows and door can make the house more beautiful and can increase the value of the house.

Decorative glass is widely used for style, beauty and elegance. It is used to add charm, modern look and originality to double glazing windows and doors.

We have installed the double-glazing windows doors with decorative glass in Richmond, Twickenham and Ealing area.

Southall Windows can offer a variety of designs to suit your style. We have only the availability of vast pre-built design to choose from.

Frosted glass – one side of the glass is frosted for privacy purposes. Mainly the bath windows and sometimes the porch windows and doors are made in frosted glass. But it is purely on the decoration of the client preference.

Here are the or designs and the privacy level:

Double Glazing windows and doors Glass types

In the double-glazing industry, there are mainly two types of glass used: standard glass and toughened glass. The thickness of each glass in double glazing 4mm and total double-glazing unit thickness may vary up to 20mm including spacer etc.

The standard glass is widely used in double glazing unless it is a requirement by law or client’s preference to use a toughened glass. Standard glass is the cheapest option for double glazing units. It is quite strong and difficult to break. It is not recommended in the double-glazed units where the safety is required by law.

The second most used glass in double-glazing is called toughened glass. It is more expensive and tougher than the standard glass. The main difference between these 2 glasses is how they break.

The toughened glass shattered into small pieces, so it doesn’t cause injuries when it breaks. Due to these extra safety features, it is more expensive than the standard glass.

The third type of glass used is tempered glass. It provides more security when it breaks. It is called laminated glass as well. When the glass breaks it remains in the shape because of the way it is made. It doesn’t fall. It is more secure and very tough to break.

The way each of the glass breaks:

Southall Windows types of glass standard toughened and tempered

Other glass options in double glazing windows and doors:

Reflective glass: This glass called coated glass as well. It is a very good tool for those who want to have more privacy and natural light at the same time. As the name suggests it is not possible to see through from the outside where the coat is applied.

It is widely used in the houses on the main road with a high footfall. They work like a mirror from the outside.

Self-cleaning glass – cleaning full house windows and doors can be very time-consuming. On the upper floors, it is hard to reach some areas, such as glass roofs and conservatories can be very hard if not dangerous.

The new technology of self-cleaning glass can sort out all these cleaning issues and can make life easier. The self-cleaning glass needs low maintenance.

Acoustic glass (noise reduction)- The acoustic glass considerably reduces outside noise. This type of glass is installed near airport areas and motorways areas. #

The areas such as Heathrow, Hounslow, Feltham are near to airports and areas such as Wembley, Richmond which are very close to big motorways have high levels of noise.

#Project : installation of Upvc double glazed Porch in Harrow

The homeowner can add a small functional double glazed porch in front of their house with a little cost and it will hugely increase the value of the house. 

The most important thing is that there is no need for planning permission from the council for most of the porches if they are built within the permitted dimension limit which can be checked with the local council.

The main benefits of having a porch are :

  • add extra space: obviously creating an extra space would be the single biggest benefit of having installed a double glazed uPVC porch with a composite door. It can add extra hanging space for coats, shoes and can keep the dirt outside the house. It can create more space for storage.

  • extra security: security is the second most important factor to have a solid double glazed porch with a solid composite door. It can create an extra barrier between your home and the outside. Check our composite door to find out more secure composite doors.  

Recently Southall Windows have installed an Upvc double glazing porch with a very traditional contemporary composite door with very traditional glass design in Harrow.

You can visit the Certass website here:

Do you know how to measure windows accurately according to the criteria set by Certass and Fensa?

My answer is YES! It is important to take the measurements 3 times. The first measurement from top, second from middle and the third from the bottom of the window. When measuring the width of the window and same principle applies while measuring the height of the window.

1) Upvc windows should be deducted 10mm from the height and width if the size is less than 1.5m.

2) Upvc coloured windows should be deducted 15mm from the height and width of the structural opening.

3) The same principle applies for the aluminium windows as well. Frequently Asked Double Glazing Questions Southall Windows

What are the dummies or “equal sight-line”? 

In a normal window with one top opening and side opening, it is normal that smaller glass will be fitted in the opening(vents) compare to the fixed where the glass area will be larger. This creates an unequal site line. 

Especially when you buy windows with Georgian or lead design I recommend you to buy dummy windows so that from outside, your windows will look symmetric.
