Frequently Asked Questions
How do I clean UPVC window frames?
Eurocell’s UPVC window frames are all designed to be easy to maintain. Simply wipe them down with a sponge and warm, soapy water whenever they are starting to look dirty. This simple procedure will ensure your UPVC window frames will look pristine for years to come.
How are UPVC windows fitted?
UPVC windows should only ever be fitted by an experienced professional. A poor installation can lead to windows that don’t work properly and make your property look tired and unloved. Eurocell has a dedicated network of approved installers operating across the UK. Contact us for more details.
Can UPVC windows be painted?
As a general rule of thumb, no. Painting UPVC windows is incredibly difficult and not recommended. In most cases, attempting to paint UPVC windows is likely to ruin their appearance. That’s why all of our UPVC windows are available in a range of attractive and eye-catching colours.
How are UPVC windows made?
Eurocell UPVC windows are designed and manufactured in the UK, as part of our market-leading sustainable approach. We recycle millions of UPVC window and door frames every year, creating new products that last for decades while dramatically reducing our environmental impact.
