Halflap

One edge of each board is trimmed to half its thickness, forming a rebate. The opposite edge is then shaped to match, creating a tongue that fits securely into the adjacent board's rebate. This design ensures a solid overlap, establishing a nearly weather-resistant barrier that preventswater ingress. The rustic and classic look of half lapadding makes it a favored option for traditional and period-style structures, while the overlap profile offers a practical and weatherproof joint.
