Insulating Hollow Core Attic Door

Mass loaded vinyl can be installed inside of the door s core or on the inside of the door in the room.

Insulating hollow core attic door.

You can purchase pre cut attic door insulation material at your local home improvement store or online. My thought is to attach a solid piece of 2 high density styrofoam insulation to these doors. Often pre primed or painted for quicker installation. As you can see using the flame test the door is a little crooked which leaves a gap at the top and the bottom which allows cold air to flow into our closet.

Cost less than solid wood doors. Since heavy mass is what blocks sound better than anything else using heavy sheets of vinyl will prevent noise from entering through the door. Your best bet is to order replacement doors for the door openings and select insula. The access door is in our closet which is fine except the fact that the crawl space has very little insulation and neither does the door.

Add foam insulation sheet. The previous owner had stapled batt insulation to the back of this hollow core door but it s clearly not enough and the magnetic latch is pretty pathetic at holding the door tightly sealed. Luan plywood doors are certainly impossible to fill with spray foam the veneer is only an eighth of an inch thick or so even the styles of the door are very thin and wouldn t resist the force of the expanding foam. Add fiberglass or rigid foam board to back of hatch.

In the closet of an upstairs bedroom there is a door about 3 4 the size of a normal door that leads to an unheated attic space. It gets pretty chilly in that closet during the winter months since the door is a simple hollow core wooden door that does very little to keep out the cold air in the attic. After you have replaced the weatherstripping you ll want to cut a piece of fiberglass or rigid foam board to size and nail or glue it on the back of the hatch door. Exterior installations of these doors can lead to delamination and deterioration above and beyond the insulation issues.

Many door makers stipulate that interior grade hollow core doors be installed only in interior partition separation applications. Lighter weight makes them easier to install. This works well if you re insulating an attic or storage space where the foam door won t be seen. So they re not drafty.

There is a hollow core door with a magnetic latch that allows access to this space. The air in these attic closets is not conditioned. Provide little in the way of. Less susceptible to expansion and or contraction.

At the time my builder compromised with me and installed pretty decent weather stripping on these doors. Even a new solid core door is not as expensive as four or five cans of insulating foam and the time and effort you would spend insulating it. Glue a 1 to 2 inch sheet of foam insulation to the back of the door. The makeup of a hollow core door is significantly different with a honeycomb cardboard interior encased by fiberboard or veneer compared with the all wood composition of a solid wood door.

Most doors especially those with a hollow core dampen sound without blocking it.
