We are now able to offer a range of slimline aluminium windows which provide the perfect replacement for aging steel windows. They are designed to achieve a slim appearance and can be installed directly into brickwork or into either existing or new timber frames. Unlike steel windows they achieve the highest levels of insulation by virtue of the most up to date polyamide thermal break and highly efficient low e insulating double glazed units. They will require no future repainting and are fitted with high security shootbolt locking mechanisms with key locking handles. They are available in a range of colours, with black or white being the most common options for traditional properties.
