OW-70 offers the slimmest of sight-lines at just 65mm for more natural light and less window profile.  Even so, a 'U' value of up to 1.2W/m²K is achievable. OW-70 windows are available with two beading options, square or chamfered, giving you ultimate flexibility in specifying a window that suits not only your personal taste, but your building’s character.

The OW-80 system, with its 91mm sight-lines will have a more visible frame but its strength offers almost unparalleled design possibilities, with huge expanses of glass available. Incredibly, when paired with the optional Aerogel* thermal break, 'U' values of up to 0.8W/m²K can be achieved - that's an A++ Energy Rating.

* Aerogel is a super-insulating silica with the lowest thermal conductivity of any known solid material. Originally developed for space travel, its unaffected by moisture or age, and provides major energy savings for the life of a home.
