What’s the difference between PVC, PVCU and UPVC?
When people refer to windows as being PVC, PVCu or UPVC, they’re all referring to the same thing: Unplasticised Polyvinyl Chloride. The confusion comes from naming conventions and contractions.
In the 1980s, the UPVC acronym was switched to PVCU to ensure consistency with other countries around the world. This was done with the best of intentions as in many languages, the noun (in this case, Polyvinyl Chloride) comes before the adjective (Unplasticised).
But due to the material’s prominence and popularity, many kept referring to it as UPVC. PVC comes from people dropping the Unplasticised part completely.
When it comes to windows and doors, no matter if it’s PVC, PVCu, UPVC or even PVC-U, they’re all the same.
What’s the difference between casement and flush windows?
A window’s casement is the part that moves (opens and closes). Standard windows are often referred to as casement windows as the casement sits proud of the surrounding frame.
On flush windows, the casement sits level with the frame. This creates a sleek and linear look that is increasingly popular.
The difference between the two might not sound much. But when you see the two window styles side-by-side, the difference is clear to see. Why not visit our showroom to see for yourself?
Should I choose double or triple glazed windows?
There are pros and cons to both options and it depends on how you want your windows to function. We’d recommend speaking with a Bon Accord Glass advisor to help determine which is the most suitable option for your needs and property.
The main difference between the two is the number of glass panes within the unit. A double-glazed window has two while a triple-glazed window has three. Triple-glazed windows are better at retaining heat and, with the correct combination of air gaps and glass, can help with noise reduction too.
One thing to bear in mind is the price differential between the two – so it’s worth talking it through with somebody from our team.
What colours do your replacement windows come in?
Thankfully, we’re far removed from the days when windows were available in white and only white. Our replacement windows are available in a huge range of colours and finishes.
If white or cream floats your boat, then great. But if modern and stylish is your thing, then you’ll love our grey, green and black frame options.
We also have a beautiful collection of wood grain finishes, ranging from the dark Rosewood effect to brighter styles such as Oak. Plus, we can offer statement options that include Chartwell Green, Dark Red and a striking Steel Blue.
Best of all, our windows are also available in colour combinations, so you can have the outside in one colour, and the inside another.
What does U-Value mean?
A window’s U-Value determines how well it retains internal heat. The U-Value is measured in Watts per square metre, or W/m2K. When checking a window’s U-Value, the lower the number the better.
All new or replacement windows must have a minimum U-Value of 1.6 W/m2K. Ask your Bon Accord Glass advisor for further details and they’ll be only too happy to help.
What does Secured by Design mean?
Secured by Design (SBD) is an official police security initiative that works to improve the security of buildings and their immediate surroundings.
SBD operate a product-based accreditation scheme, the Police Preferred Specification. This provides a recognised industry standard for all products that play a part in a building’s security, such as windows and doors, as well as internal components such as locks and hinges.
Our manufacturing partner, Conservatory Outlet, is a longstanding and registered member of Secured by Design. Many of our products meet this specification.
