Sliding Sash Windows

Only with Pennine, can people of the North East get sliding sash windows that have guarantees on quality, price and service!

Sliding sash windows have remained popular in the UK since first appearing in the late 17th Century. Found in all home styles in the North East, sash windows have proven to be incredibly versatile; making them the perfect choice for people wanting a timeless look for their home. Featuring 2 panes of individual glass, sash windows are unique in the way they can be opened fully from top to bottom. With their often classic grid design featuring small panes of glass arranged in a variety of patterns ranging from ‘2×2’ up to ’8×8’, sash windows provide fantastic design freedom that give your home a classy look.


The Pennine Way isn’t about what we do; it’s about how we do it.

The Pennine Way forms the solid backbone of our company. It defines what it feels like to work with Pennine, by highlighting what’s most important to you.

5. One Point of Contact - We’ll give you one point of contact for each stage of your Pennine project, so you’ll always know who to go to if you need information, help or support.

6. Absolute Respect - We always treat your home like the palace it is. Your space, your rules. We’ll use dust covers on our way in and tidy on our way out.

7. People People - At every stage of the process, we only ever introduce you to people who want to make the process a pleasure for you. You’ll feel supported and listened to – every step of the way.
