Frequently Asked Questions

What are uPVC sliding sash windows?

uPVC sliding sash windows blend the traditional look of vertical sash windows with modern uPVC materials. The moving sash gives you better ventilation and airflow while providing a classic finish.

Are uPVC sliding sash windows cheaper than timber windows?

Yes. uPVC sliding sash windows are a cost-effective alternative to their timber counterparts, and they can also improve thermal efficiency and sound insulation.

Are sliding sash windows secure?

Our sliding sash windows are built with security in mind. They are equipped with multi-point locking systems, which help prevent forced attacks and keep you safe for years to come. 

Are uPVC sash windows low maintenance?

Yes. You will be pleased to know that our uPVC sash windows are easy to clean and maintain. They don’t need to be painted or stained and can be wiped down with a damp cloth and soapy water, so they look pristine.

Do I need planning permission to install my sliding sash window?

Generally, you don’t need planning permission if you’re replacing old windows with similar ones, as long as you’re not making any structural changes. However, if your property is listed or in a conservation area, you might need to check with your local council.

Can my uPVC sliding sash windows reduce outside noise?

Yes, especially if you choose double or triple glazing. These uPVC sliding sash windows are soundproof, ensuring they are a good choice for noisy areas or busy roads.

Do my sliding sash windows offer improved ventilation?

Yes, sash windows offer improved ventilation. Their design allows both the top and bottom sashes to open, promoting efficient airflow by letting warm air escape from the top and cooler air enter from the bottom.

How secure are your sash windows?

Our vertical sliding sash windows are very secure. They contain high security multi point locking systems to stop unauthorised access, giving homeowners complete peace of mind. The sash windows come with restrictors that stop the bottom sash from sliding fully, so little fingers won’t get trapped.
