Fortress™ Internally Beaded Windows

 

Fortress™ 70 are amongst our most sought-after windows and we have supplied and fitted them for customers across the north east. The windows combine state-of-the-art design with exceptional security featured as well as the highest standard of engineering work. They are ideal for anyone looking for a robust take on a classic, traditional style and you can get in touch with us at any time if you have any queries about them. 

Like the Super Fortress™ range, Fortress™ 70 offer timeless style with unrivalled innovation and build quality. The windows offer a fully-chamfered outer frame, sash and glazing bead. They can enchance the appearance of virtually any home, inside and out. They feature low sightline grey weather seals plus a multi-chambered construction. What's even better is that they provide a robust barrier against the testing British climate whilst keeping heat trapped inside your home and diminishing the amount of noise that enters the home from the outside. 

The windows can enchance the value of your home and improve your quality of life. At Oaktree, we can offer you in-depth advice on all of our products to lead you to an informed decision. As a premier supplier and installer of some of the market's most renowned windows, we can be relied upon to meet your expectations whilst offering you some of the best prices in the north east.
