Why Is the Door Harder to Close Only in the Afternoon?
Direct sun can heat the exterior surface of a door while the inside face remains much cooler.
That temperature difference can create temporary thermal movement.
On some doors, this may appear as:
- Slight bowing
- Changed weatherstrip contact
- Temporary latch difficulty
Why Does Colour Matter?
Dark finishes generally absorb more solar energy than light finishes.
A dark south- or west-facing door may therefore experience stronger surface heating.
Is Every Bow a Product Failure?
No.
The contractor should determine whether the problem comes from:
- Thermal movement
- Frame installation
- Hinge adjustment
- Structural movement
- Permanent panel damage
Why Not Immediately Adjust the Frame?
If the condition appears only during peak sun and disappears later, aggressive adjustment may create a different problem when the door cools.
Product Requirements Matter
Door manufacturers may have specific recommendations about:
- Paint colour
- Storm doors
- Solar exposure
- Warranty limitations
Diagnose When the Door Moves Before Deciding Why It Moves.
Envirotech Exteriors can assess the entire entry system when a door operates differently under changing weather conditions.
