The Walls Are Open, Now What?

Spray Foam Insulation in Hackensack pays off best when the walls are already open. Hackensack sits on the east shore of Birch Lake, with Ten Mile Lake and Pleasant Lake close by, and a lot of the building here is remodeling and adding on to older lake homes. When siding comes off or drywall comes down, you get one chance to fill those walls well before they are closed again.

What the code summary calls for

The efficientwindows.org summary of Minnesota's energy code lists wood-frame walls in Cass County's Climate Zone 7 at R-20 plus R-5 of continuous insulation, or R-13 plus R-10. In plain terms, the cavity alone is not quite enough, and something continuous on the outside or inside helps cover the studs. Closed-cell foam in a 2x6 wall gives a high R-value in the cavity and seals air at the same time.

Open cell or closed cell in walls

Open-cell foam weighs less and costs less, and it fills the cavity and seals air well, but it lets more vapor through, so the wall needs a proper vapor control layer on the warm side. Closed-cell resists vapor and adds some stiffness. We explain which fits your wall and how it works with any foam board on the outside.

Additions on lake homes

An addition ties new framing into old. The joint between them, plus any new floor over a crawl space or slab, is where drafts show up. We pay attention to those seams so the new room is not the cold one.

Moisture near the water

Homes along Birch Lake and Ten Mile Lake deal with damp summer air. In winter, indoor humidity tries to move out through the walls. Sealing air leaks keeps that moist air from reaching cold sheathing, where it could condense.

Hackensack Questions

We are re-siding our Hackensack house. Is that a good time to insulate?

It is an ideal time. With the siding off, walls can be filled and foam board added outside before new siding goes on. Talk to us before the siding crew starts.

Does spray foam in the walls replace a vapor barrier?

Closed-cell foam at enough thickness slows vapor a lot. Open-cell does not, so it needs a separate vapor control layer. Your inspector may have a view on this for permitted work, so we confirm before installing.

Can you insulate an addition and the old house at the same time?

Yes, and it often makes sense, especially at the seam where the two meet. We quote each part on its own line.

How soon can drywall go up after foam?

Foam cures quickly, but the space needs to air out before people work in it. We give your contractor a clear time, and we trim the foam flush with the studs so drywall goes on flat.
