Can you staple unfaced insulation?

Unfaced insulation goes up more quickly than insulation with paper or plastic facing. Flaps on faced insulation must be stapled between rafters to hold it in place. However, the lack of facing means that you must add a moisture barrier over the insulation.

How do you fasten unfaced insulation?

Place unfaced insulation on top of existing material, such as loose-fill cellulose. Press the insulation firmly into place between joists, taking care to not compress the fiberglass and reduce its efficiency. Fasten batts loosely to perpendicular joists with plastic straps just to keep it from shifting.

Should you staple faced insulation?

Use enough staples to hold the insulation firmly in place (about every 8") and avoid gaps and “fishmouths” between the flanges and framing.

What can I use to hold up insulation?

There are many options for keeping roof insulation in place, including using metal insulation supports, insulation netting, garden netting, chicken wire, or nylon straps. Metal insulation supports and nylon straps are good affordable options, while chicken wire looks nicer but is more expensive.

Should insulation seams be taped?

Yes, you tape any insulation's lateral seams, especially any fluffy stuff... aluminum HVAC tape lasts the longest. The fluffy stuff really only works best in dead air space. Which also means the un-faced side (where you don't tape anything).

When to Use Faced or Unfaced Insulation

Can I use a pneumatic stapler for insulation?

People use pneumatic staplers to attach materials that might become easily dislodged if they were attached with a small nail. These include: insulation, house wrap, roofing felt, and hardwood flooring or engineered flooring underlayment.

Is it OK to use unfaced insulation on exterior walls?

Unfaced insulation is non-combustible.

However, it's common for a layer of faced insulation to be used in the exterior walls and attic ceilings to prevent water from entering the home, while unfaced insulation can be added to improve the heat retention ability and reduce the risk of fire.

Do you need a vapor barrier with unfaced insulation?

In most climates, it needs a vapor barrier. Some builders rely on batts with attached kraft-paper facing to do that job, but Tom recommends unfaced batts, covered in plastic with all the seams taped shut.

Can you use duct tape on insulation?

Although it may technically offer slightly more protection against exposed wires than no covering at all, duct tape is NOT an electrically insulating material and is entirely unsuitable for proper protection against live current.

What is a heavy duty staple gun used for?

A staple gun or powered stapler is a hand-held machine used to drive heavy metal staples into wood, plastic, or masonry. Staple guns are used for many different applications and to affix a variety of materials, including insulation, house wrap, roofing, wiring, carpeting, upholstery, and hobby and craft materials.

Do staple guns bend the staples?

Because there's more power behind them, when an electric or pneumatic stapler tries to fire too many staples at once, it can cause parts of the tool to bend, damaging the entire model.

What are 18 gauge staples used for?

At 18-19 gauge, medium wire staples can be used for heavier upholstery, cabinet assembly, paneling, trim, sheathing, underlayment, siding and soffits. Heavy wire staples are the strongest, ranging from 15-17 gauge.

Can you spread loose insulation by hand?

Wouldn't it be far easier to just bring a few bales home and sprinkle it around by hand? Yes, it is. And you can absolutely install loose fill insulation without a machine. If you have a small section that you need to tackle, this is a great way to get it done without the hassles of weighty machinery.

Can you spread insulation without a blower?

Since cellulose insulation is compressively packaged you cannot install it without using a blowing machine. I do not recommend trying to do this by hand. "A few bags" may not qualify you for loan of a machine, but you can certainly rent one from a big box home center or an equiment rental service.

What is the difference between faced and unfaced insulation?

The Difference Between Faced And Unfaced Insulation

Faced just means that kraft paper is attached to the insulation itself. The paper helps improve the sturdiness of the insulation so it doesn't fall down as much. Unfaced insulation is just as good as faced, but it doesn't have that paper attached to it.

Where is unfaced insulation used?

Unfaced insulation is great for new construction, remodels, walls, floors, ceilings, basements, attics and crawlspaces. It's best used for interior wall applications that do not face the outside and also in rooms that don't need moisture control, like living rooms, dining rooms and studies.

How do you insulate a wall without studs?

Which side of insulation goes against the wall?

The first layer should have the facing against the drywall to act as a vapor barrier. (The general rule for insulation is that the facing always goes toward the conditioned space.) The second layer of insulation should be unfaced so that moisture doesn't collect between the layers.
