OW - 70 Slimline
The difference between OW-70 and OW-80
The main difference between OW-70 and OW-80 is the way that they look.
OW-70 offers the slimmest sightlines at just 65mm wide, ideal for those looking to maximise on natural light and views. OW-80 may not offer sightlines as slim as OW-70, however, it offers an internal flush casement, which OW-70 cannot provide.
Both OW-70 and OW-80 are manufactured using premium grade aluminium, are durable and low maintenance, and come with an industry-leading guarantee of up to 20 years.
