Installation Guidance - Decra Plus Tile D type Box Barge Cap

Setting Out Gables
Fix the barge boards in a position where they are level with the tops of the tile battens.

Underlay should turn up against the edge of bargeboard by 38mm.

On top of the tile battens nail additional gable runner battens up the slope of the roof and along the vertical face of the bargeboard. These battens should be set 85mm from the outer top edge of the bargeboard (see drawing to right).

 

Gables
The gable detail is finished using a Decra D Box Barge Cap. The D Box Barge Cap is similar to the D Ridge in appearance but the angle is much steeper (see drawing to right).

 

Decra tiles to be cut and bent forming an upstand against a gable runner batten.

Before installing the first D Box Barge Cap it is necessary to trim and fold the ends to form a blocked end at the eaves. Mark out a line 40mm from the bottom edge of D Box Barge Cap. Cut away areas shaded black on image to right. Fold vertical flap 90° in on itself, fold horizontal flap down by 90°.

 

The D Box Barge Caps have a slight taper in their design. Place the wider end of the D Box Barge Cap over the narrower top end of the D Box Barge Cap beneath creating an 80mm overlap.
Nail D Box Barge Cap into position using 4 nails skew fixed down the inner face of the D Box Barge Cap into the upstand of the tile and 4 horizontally (see drawing to right). Care should be taken to ensure D Box Barge Cap are correctly lapped.
