This video is Part 1 of the "Key Points for Prospective Homeowners" series, which simplifies the difference between water-repellent ALC and waterproofing, topics frequently confused by those preparing to build an ALC house. Many people ask the following questions: “Does using water-repellent ALC make it waterproof?” “Do I not need exterior wall finishing?” “How is it different from regular ALC?” To start with the conclusion, water-repellent ALC is not waterproof ALC. Water-repellent ALC is low-absorption ALC designed to reduce water absorption compared to regular ALC. However, it is neither a product that absorbs absolutely no water, nor is it a waterproofing material that prevents rain from leaking. In this video, we examine the difference between water-repellent and waterproof, the manufacturing methods and physical properties of water-repellent ALC, the principles of silicone oil water repellency, data on Japanese Asahi Hebel SI panels and Siporex Dry, the term "low-absorbency ALC" used in domestic patents, and even the points prospective building owners must verify directly before signing a construction contract through KIPRIS patent searches. In particular, it can be observed that even in materials from Japanese manufacturers, water-repellent ALC is described as "low-absorbency ALC panels" rather than "waterproof ALC." Exterior wall finishing is still required even when using water-repellent ALC. Exterior wall finishing materials must consider both water repellency, which reduces rainwater absorption, and moisture permeability, which allows water vapor inside the wall to escape. Furthermore, the use of water-repellent ALC should be considered even more carefully in cold regions. This is because while water repellency is advantageous for inhibiting absorption, it can be disadvantageous for the dispersion and drying of moisture that has entered the interior. ■ Main Contents 00:00 Water-repellent ALC is not waterproof ALC 00:50 The difference between water-repellent and waterproof 03:25 Principles and manufacturing methods of water-repellent ALC 04:30 Silicone oil and low absorption 05:30 Comparison of absorption rates between standard ALC and water-repellent ALC 07:36 Precautions for cold regions 11:39 Why we look at Japanese ALC data together 13:16 Background of the development of water-repellent ALC 14:00 Japanese Asahi Hebel SI panel data 15:15 Siporex Dry low-absorption ALC data 17:25 Expressed as “low-absorption ALC” in domestic patents as well 17:46 How to verify directly using KIPRIS patent search 18:37 FAKOHAUS's conclusion 21:16 Preview of Key Points Part 2 ■ FAKOHAUS / ALCMATE Co., Ltd.
