Chelmsford How To Measure A Double Glazed Unit

How to measure a double glazed Window

           HTMG     

Most double glazed sealed units in PVCu frames are either 24mm or 28mm thick and wooden frames can be any thickness from 14mm upto 28mm thick. You should be able to check with your supplier for these dimensions. If you purchased the windows/doors a long time ago the information should be on your receipt or warranty.

If you do not have this information to hand then you will have to calculate the measurement yourself. This is tricky but it can be done and you will need a tape measure and a straight edge such as a piece of wood.

Firstly measure how thick the PVCu frame/opener is and then place a straight edge against one side of the frame and let it protrude into the area of the glass (as the picture above).

As the straight edge will be flat against the PVCu, it should be floating away from the glass. Measure the gap (A to B) from the glass to the inside of the straight edge and write this down. Do the same with the other side of the frame and note the measurement again.

To calculate the thickness of your double glazed sealed unit you would need to deduct these 2 measurements from the thickness of the PVCu frame and you should have a measurement of either 24mm or 28mm.

As an example, the frame that holds the glass is 62mm thick, the A to B gap (as the photo above) of one side is 17mm and the A to B gap of the other side is also 17mm. This gives us a measurement to deduct of 34mm. 34mm deducted from the frame thickness of 62mm is 28mm and this figure is the thickness of the sealed unit in this frame.

Frequently asked questions

This type of glass adds additional strength to your windows. To gain entry, a burglar would have to strike the glass repeatedly in the same spot in order to make a small opening. Most burglars are reluctant to create this type of noise for fear of being detected.

These glass sheets are held together permanently by an interlayer such as polyvinyl butyral (PVB). Laminated glass is about two times stronger than standard float glass of the same thickness, with the advantage that in case of breakage, it generally holds together by breaking into a spider-web pattern.

Float glass: This is the most budget-friendly and has no natural tint. It is a single piece of glass that breaks into sharp shards when hit with force. Float glass can, however, undergo a lot of chemical processes to be strengthened. It can be used in single-pane and even double-pane windows once it's been enhanced.

Look closely at the glass edge: tempered glass will have a smooth, slightly rounded edge without sharp corners. Untempered glass has a sharp, unfinished edge. You may also notice small nicks or divots in the glass edge. Tempered glass has undergone intense heating and rapid cooling, so its surface is more durable.

Annealed Glass      Less expensive, Good visibility
Laminated Glass    Strong material, shatter-resistant glass
Low-E Glass          Energy-efficient, thermal coating that lasts 10 to 15 years
Tinted Glass          Promotes greater privacy, heat transfer resistant

Laminated glass products make float glass suitable for today's demanding architectural applications such as: noise reduction, hurricane impact-resistance, blast mitigation, forced entry, protection from broken glass – or a combination of these.

The cost factor is a significant consideration, as it tends to be more expensive than standard glass options.

As the most common type of affordable glass, float glass will often be used for low-cost windows and smaller display cabinet-style doors, as well as being the base material for almost every other application.

Toughened is around 5 times stronger than laminated. It, therefore, needs to be hit a lot harder for the glass to break. When toughened is hit with enough force, it will break up into lots of small, blunt pieces rather than long sharp shards.
