Beadings on external and internal double glazed windows are the arrangement of the glazing bead, which is the strip that holds the glass unit in place in the window frame. Each of them has its own benefits and drawbacks and the difference between the two is not black and white.
External Beading
External beading is a technique where the glazing bead is applied on the outside of the window.
Pros:
– Enhanced weather resistance in the areas that are more exposed
– A thinner window profile from the inside
– Some people find it more aesthetically pleasing especially in the older timber windows.
Cons:
– The conventional opinion is that it is less secure since the beads can be taken out from the outside
– More vulnerable to weather conditions which may reduce the product’s life
Internal Beading
Internal beading is a process where the glazing bead is applied on the inside of the window.
Pros:
– Considered to be more secure as the beads are sealed from the outside
– Protected from the weather conditions that may increase the product’s lifespan
– Easier to install from the inside especially for high rise buildings.
Cons:
– May have some problems with leaks in some of the designs
– May appear more bulkier from the inside.
Which is the Best?
There is no such thing as a completely perfect choice since everyone has different needs and wants:
1. Security: Contemporary externally beaded windows are security certified and can therefore be classified as secure. But, internally beaded windows are generally thought to be more secure.
2. Aesthetics: This is a matter of personal preference. Some people like the slim profile of externally beaded windows when viewed from the inside, while others prefer the simplicity of internal beading.
3. Weather resistance: Externally beaded windows can be more efficient in very windy areas.
4. Installation: Internally beaded windows are easier to install from the inside, which is an advantage in high-rise buildings.
5. Longevity: Internal beading can help to protect the glazing components from the elements.
Therefore, it can be noted that both types can be appropriate depending on the particular features of the structure and the wishes of the owner. The current production methods have basically eliminated the security issues with externally beaded windows, so both of them are suitable for most applications.
The best choice ultimately depends on factors such as the building’s location, security requirements, aesthetic preferences, and ease of installation.
