Simply so, can you fill a hollow core door?
A hollow core door is lightweight andinexpensive, but it does have a downside: it allows sound topass through easily and is impossible to insulate internally. Theinside of the hollow core door is actually filledwith a honeycomb or baffle of cardboard that adds rigidity to thethin veneers of the door.
Correspondingly, how do I fill a hole in a wooden door?
How to Repair Holes in Hollow-Core Doors
- Place a piece of solid wood over one side of the hole.
- On the other side of the hole, spray foam insulation into thecavity.
- Use a utility knife to shave the foam on both sides of thedoor.
- Scrape the compound so that it's flush with the rest of thedoor.
Hollow core doors normally feature a timber framemade out of hardwood or pine, along with solid 'lock blocks'on either side of the door to allow a handle and otherdoor furniture to be mounted on either side of thedoor. The 'core' of the door is filled eitherwith waste paper or a cardboard lattice or honeycomb.
