Aluminium windows today have come on leaps and bounds from their historic counterparts. Gone are the days of draughts and an unsightly appearance.

Opting for aluminium windows today means insulating your home, improving aesthetics and having the ability to incorporate larger panes of glass.

State of the art materials make for modern performance

The modern aluminum window profiles that we use here at Dolphin boast a multi-chamber design. This means that far more heat can be retained within the window frame itself. Combined with good quality glazing, this removes the risk of draughts and vital heat escaping from your home – rooms become useful and pleasant all year round, however cold it is outside.

Forget maintenance worries – aluminium windows last

Lightweight and strong. Two factors you didn’t think could go together? Dolphin’s aluminium windows are light enough to be fitted quickly (interrupting your life as little as possible) but strong enough to incorporate even reinforced glass options or triple glazing. They also won’t rust, corrode, discolour or warp, even in areas susceptible to adverse weather conditions or pollution from nearby traffic links – they will maintain their stylish appearance and functionality for decades to come, not just a few years.

With more glass and slimmer sightlines, it is easy to optimise the natural influx of light to your home – whether you want your living room, conservatory, kitchen or other living space to look and feel more spacious. Aluminium windows are available for many styles, including sash, casement and tilt and turn – simply enquire today.
