NT45 45mm 1¾" Non Thermal Aluminium

NT45 Ultra Slim Non Thermally Separated Aluminium

Multi purpose and Lightweight


The 45mm 1 ¾” Aluminium frame offers a lightweight solution to our other products and is ideal for internal doors, room dividers, pool enclosures and balcony’s.

Although the slimline NT45 frame has tighter stacking space and a lightweight feel compared to our standard products it doesn’t lose any of the benefits the standard frame offers. Just as durable and strong and although used mainly for interior doors they are just as weather tight and secure.
