Identified Causes
3 原因Insufficient Insulation Thickness
90%The existing insulation may not be thick enough to provide adequate thermal resistance, leading to heat transfer in both directions. This is a common issue with older homes or if insulation hasn't been updated to current standards.
Air Leaks and Gaps
80%Unsealed gaps and cracks in the attic floor or around penetrations (like light fixtures, plumbing vents, and attic hatches) allow conditioned air to escape and unconditioned air to enter, bypassing the insulation.
Degraded or Compressed Insulation
75%Over time, insulation can settle, compress, or become damaged, reducing its effectiveness. This can happen due to foot traffic, moisture, or simply the natural aging process of the material.
