Cedar Grandstyle 70mm Cladding

Cedar Grandstyle 70mm Cladding (WC2185)
Cedar Grandstyle 70mm Cladding (WC2185)

Modern shadowline profile

The crisp, square edges of Grandstyle timber cladding create a sleek, contemporary look. 

Made from stunning solid Western Red Cedar, Grandstyle tongue-and-groove boards are available in three different widths. The three sizes can be used interchangeably to create interesting effects.

The boards can also be secret-fixed or face-fixed.

Grandstyle has been specially designed to allow for natural timber movement across the seasons, which makes it the ideal choice for areas that are exposed to the weather. 

Cedar Grandstyle cladding can be coated with Sikkens products to protect and maintain the colour of the timber or coated with Cutek oil and left to weather naturally to silver-grey.
