How to Interpret It: Check the angle of the threshold. It should slope downward away from the door. Use a level and a small shim to measure the slope.
How It Relates to Other Metrics: Sill Slope is related to Threshold Height Accuracy and Effective Sealing and Weatherproofing. It impacts Long-Term Durability.
Personal Story & Data-Backed Content: I had a client complain that water was seeping under the door during heavy rains. I discovered the sill slope was minimal. I replaced the threshold with one that had a more pronounced slope.
Actionable Insight: Ensure the threshold has a noticeable downward slope away from the door.
21. Jamb Material Compatibility: Avoiding Reactions
Definition: Jamb Material Compatibility refers to ensuring that all materials used in the door jamb assembly (wood, fasteners, sealants) are compatible with each other to avoid chemical reactions or degradation.
Why It’s Important: Incompatible materials can lead to corrosion, discoloration, or weakening of the structure.
How to Interpret It: Research the compatibility of different materials before using them. For example, some sealants can react with certain types of wood or metal.
