Fully Reversible Combination Windows
There’s no doubt about it – BJM’s combination windows owe their well-deserved popularity to their astonishing versatility. By combining high-performance components with imaginative design and engineering, we’ve created an attractive and innovative window offering a variety of opening configurations in one package.
Choose from a side or top projecting opener, a fully reversible top or side swing, or even standard butt hinges – the real beauty is that a single great-looking window offers a fantastic range of opening options for every situation.
