Yes, every detail of our sash windows has been designed with security in mind. As standard our sash windows come with one or two locks (depending on window size) and you have the option of choosing a key-locking lock at no extra cost. You can take the security of your new sash windows to the next level by taking advantage of our comprehensive security upgrade. With this upgrade, your windows will feature top sash security blocks, two enhanced locks and reinforced tilt latches.
