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.

UPVC tends to be the favoured window material for millions of property owners because of its many different qualities such as the durability, energy efficiency and security it provides. Its outstanding thermal efficiency alone should be enough to persuade you to choose it as it will ensure that your windows reduce heat loss and drive down the cost of fuel bills. Looking to replace an arched window? UPVC can be shaped accordingly, whilst also featuring the familiar curved external bead.

Our aluminium range of products continue to grow at a rapid rate.

You can’t fully appreciate the toughness of aluminium until you experience it in person at which point you will soon come to understand why it is arguably the fastest-growing material utilised in home improvement offerings. The slender sightlines that can be created courtesy of the aluminium profile means that a great expanse of glass can be inserted into the final frame, giving the light of the sun a less restricted pathway through the glass. As a finishing touch, check out our many powder-coated colours and timber effects.
