Wintec Systems offers a range of building products designed to exceed all relevant Australian standards. Be it weather or energy efficient door & windows with larger uninterrupted views, or low maintenance exterior cladding - Wintec Systems has the product.

Introducing: Ulltraclad® - a powder coated Aluminium interlocking exterior cladding system that can be applied both horizontally and vertically. It is suited to both residential & commercial building applications and is available in a wide range of colours in modern or classic designs.

Weatherboards are produced in a rusticated weatherboard profile, with either a smooth, corrugated or grooved face (Tee Board), a bevel back weatherboard profile (Traditional), or a flat face with negative joint detail (Shadoline).

They are produced in 6 different profiles which range in width from 140mm up to 205mm, and are supplied 5m and 6m lengths.

When installed, the cladding is effectively 15mm thick with the powder coat featuring on the exposed surfaces.

This system is applied to the external wall framing over an absorbent building wrap which has been extensively tested to cyclonic conditions.

What people are saying about UlltraClad®


“Living on a steep hill, four storeys high forced us to look for an innovative cladding product that meant no maintenance, looked architecturally smart and was well constructed. We were so pleased when we came across the Wintec brand as it ended up being the answer to all our issues.”

John Harrison – Hamilton, Brisbane

"In designing and building our display home in Bulimba, one of the most important aspects of the brief was to use materials which are aesthetically pleasing, cost effective and low maintenance.We used the Wintec Shadowline profile cladding system both vertically and horizontally on the entire first floor of our display home and it is the outstanding external feature of the home.

We find the look of the product, the cost, the low maintenance aspect and the ease of installation all add up to a product we are happy to specify to our prospective clients"

Bob Antic, Principal and Licensed Builder – Space Constructions, Brisbane
