What are the steps for installing a ridge purlin on a cellular concrete gable wall?
Here are the steps for installing a ridge purlin on a cellular concrete gable wall: 1. **Create a notch**: Plan a notch in the gable's apex to insert the wooden purlin. Ensure the purlin's end is set back approximately 2 cm from the exterior face of the load-bearing wall. 2. **Fix the purlin**: Use special 175 mm long aluminum nails to fix the purlin to the cellular concrete gable wall. 3. **Apply a render**: Cover the junction with an exterior waterproofing render. For better adhesion of the render, embed a strip of square-mesh metal grating into the render, ensuring it extends beyond the junction on both sides.
