Passive House NI supply windows designed with nine chambers, as opposed to the standard three or five chamber window, providing a better thermal performance.  These come with either 28mm double glazing or 44 mm triple glazing giving a good thermal and acoustic performance. These windows will enhance any property whether it be a period residence or a newly built home.  Residence 9 come in a wide range of colours and colours can be mixed, i.e. external colour doesn’t have to be the same as the internal finish.  This 9 chamber frame design gives U-Values of 1.2W/m2K and 0.8 2W/m2K with standard 28mm and 44mm argon filled units.
