Construction variations (e.g., inset channels, overlapping profiles) affect sealing choices. Inset channels accommodate specific compression bulb seals. Overlapping profiles require specialized configurations for effective sealing. Ignoring these variations can lead to gaps and drafts. For example, using standard adhesive-backed tape on an overlapping frame profile will likely result in an incomplete seal.
-
Frame Condition
Existing damage (rot, warping, misalignment) requires remediation before weather stripping installation. Attempting to seal a damaged frame compromises effectiveness and potentially exacerbates the problem. For instance, applying weather stripping over rotted wood provides only a temporary solution, while the underlying issue continues to deteriorate.
-
Gap Size and Shape
Gap dimensions between the door and frame dictate the appropriate size and shape of the weather stripping. Large gaps require more substantial sealing solutions, while irregular gaps may necessitate custom fitting or the use of flexible materials that conform to the shape of the opening. Accurately measuring the gaps before selecting weather stripping is essential for ensuring a proper fit and effective seal. Using a seal that is too small for the gap will result in continued drafts, while a seal that is too large can interfere with door operation.
