Product description

Royal Celect® Board and Batten

The Royal Celect® Board and Batten product is an exterior cladding system supplied in boards measuring 228 mm (9 in.) wide with an exposure of 190 mm (7.5 in.), a nominal length of 3 048 mm (10 ft.) and a nominal thickness of 95.25 mm (3.75 in.). The product is made of cellular PVC and is installed vertically. The exterior face of the panels is embossed to provide a wood-like pattern. The panels are available in different colours. 

The Royal Celect® Board and Batten product must be installed over furring and Code-acceptable sheathing and sheathing membrane in all regions.

Royal Celect® Clapboard

The Royal Celect® Clapboard product is an exterior cladding system supplied in planks measuring 216 mm (8.5 in.) and 137 mm (5.5 in.) wide with an exposure of 178 mm (7 in.) and 100 mm (4 in.), respectively, and a nominal length of 3 759 mm (12 ft., 4 in.) and nominal thickness of 8.7 mm (11/32 in.). The product is made of cellular PVC and is installed horizontally. The panels are profiled along the top and edges so that the horizontal and vertical joints are clipped together, creating a shiplap joint. The exterior face of the panels is embossed to provide a wood-like pattern. The panels are available in different colours.

The Royal Celect® Clapboard product can be installed directly over the Code-acceptable sheathing and sheathing membrane in non-coastal applications with a moisture index (MI) of ≤ 1. In coastal regions with an MI of > 1, the product must be installed over furring.

All products must be installed in accordance with the manufacturer’s specifications and the conditions and limitations listed below. The horizontal cladding product must be installed using 50 mm (2 in.) long hot-dipped galvanized roofing nails with a minimum spacing of 406 mm (16 in.) on centre (o.c.). The vertical cladding product must be installed using 50 mm (2 in.) long hot-dipped galvanized roofing nails with a minimum spacing of 203 mm (8 in.) o.c.

  • The cladding system is intended for use on buildings not exceeding 12 m in height or 3 storeys.
  • The Royal Celect® Clapboard cladding product can be installed directly to the sheathing in non-coastal areas (MI ≤ 1) as defined by Sentence 9.27.2.2.(5), Minimum Protection from Precipitation Ingress, of Division B of the NBC 2015 in conformance with Sentence 9.27.2.2.(6).
  • The Royal Celect® Board and Batten cladding product must be installed over furring in coastal and non-coastal areas (MI > 1 and MI ≤ 1) as defined by Sentence 9.27.2.2.(5) of Division B of the NBC 2015 in conformance with Article 9.27.5.3., Furring, of Division B of the NBC 2015 and in conjunction with a minimum vented air space or capillary break of 10 mm conforming to Clause 9.27.2.2.(1)(a) and Sentence 9.27.2.2.(2) of Division B of the NBC 2015.
