Installation Guide

6. Gable triangles and supports of the roof (purlins)
Please note that the uppermost planks of side walls are beveled to follow the inclination of the roof. The
uppermost planks on some models are short, lower and beveled (please see the drawings of wall
construction). They will be screwed or nailed (require pre-drilling) to the plank below. When the walls are
complete 2-3 people are needed to install the gable triangles. Check that the side walls are vertical;
sometimes they need to be pushed slightly inwards to get the gable triangle to fit. Ensure that gable
triangles are not left unsupported before installing the ridge purlin. The purlin should be slid into the
notches of gable triangles so that the upper edge is flush with the edge of the triangle. Other purlins can
then be installed in the same way, then pre-drill and nail the gable triangles to all the purlins (drawing 10).
