What Type of Glass is Best for uPVC Sliding Sash Windows?

Whatever it is, there’s a glazing option to suit your needs.

Here at Manchester Window Factory, we offer a wide range of glazing options to suit your home and meet the room’s requirements. All our ranges are available with triple glazing, but you can also find glass designed to solve specific problems.

How Much Maintenance Do uPVC Windows Need?

One of the most appealing aspects of uPVC windows is that they do not require much maintenance. 

The uPVC frames and most styles of glass only need cleaning with warm soapy (washing up liquid) water and a soft, microfibre cloth when they get dirty. Remove any debris before you start cleaning, and remember to check for any cracks or gaps. Our sliding sash windows can be cleaned inside and out from the safety of your home. Consider a telescopic window wiper (squeegee) for any hard-to-reach windows, or hire a professional window cleaner. 

Pro tip: Don’t wash your windows on a hot sunny day as they will dry too quickly and dry streaky.

However, there are more moving parts with sliding sash windows, so ensure you clean all the mechanisms thoroughly to prevent them from sticking.

Can uPVC Sliding Sash Windows Be Repaired or Restored?

uPVC is strong and hardwearing, equal to almost anything the British weather throws at it. Our uPVC windows are guaranteed for 10 years, so you should not have to complete any repairs or restorations during that time. The uPVC does not require painting, and cleaning and maintenance are a doddle with our tilting options. 

Sometimes, you may have a problem, such as stiff windows, a broken seal or difficulty opening or locking the window. Most issues have a simple remedy, such as lubricating the hinges or reinforcing the seal.

uPVC can occasionally crack when subjected to extreme temperatures or many years of use, but this is rare. If uPVC does crack, the size of the crack will determine the best course of action. 

A small crack may be fixed by applying plastic filler. Once the crack expands, it can be difficult to repair. A replacement window is usually advisable. If a uPVC window needs repairing within your warranty, your insurance will cover the cost.

How Long Does it Take to Install Replacement uPVC Sash Windows?

Installation time will depend on the number, size, and location of your replacements. On average, you are looking at a few hours to a full day’s work for a qualified fitter. If the windows are not easily accessible, it will take longer (and cost more) to replace them.

You must factor in the removal and disposal of the old windows, which can take longer if they are damaged. 

The weather and time of year may also affect the installation time, as fitters tend to install windows one at a time during the winter to prevent draughts. Bad weather can also cause delays.
