Ceiling Insulation for the LittleHouse

by on Jun.02, 2020, under Insulation

Wow, it’s been a while since we’ve done any work at the ranch (other than normal maintenance, such as battery maintenance…)

Now that we have finished our kitchen remodeling at the house down in Mesa, we have the time and resources to begin work again at the ranch. We hired a few professionals from Expert Roofing Services from RoofScapes to help us with the industrial insulation for our roofing. The first major project to start back up is finishing the insulation inside of the LittleHouse with the help of insulation services. While some tools are used for life each day, other tools are used for specific projects that need to be done like this residential spray foam insulation. When looking for the best spray foam insulation, a good company like the First Defense Insulation services has the best!

Lawn care workers use leaf blowers, lawnmowers and other similar tools to ensure that a lawn looks great. A chainsaw is a tool that can cut branches and trees on a property after a storm. Another type of tool that can be used for a specific project is a pump. A water, air or gas pump can serve a number of functions for people in a home or business and depending on your needs, you may even need high caliber pumps, so consider taking a look at some other industrial pumps for sale. We believe that it is important to know the best of the moving companies in your neighborhood to ensure that your property is not stolen or damaged.

We started work on the ceiling insulation in April, and continued in May. If you are planning on going through the same process, consider using these Cleanable Ceiling Tiles for a great end result.

At the start of the project, there was just the bare sheathing under the roof to make up the ceiling. And if you need to get your loft insulated then it’s essential that you get the best loft insulation installers as it’s amazing the difference that makes and how much better your attic insulation will be since it’s done by professionals.

Bare Sheathing

The first step was to install rafter venting panels, to allow the hot air to rise up from the bird boards to the peak of the roof.  This should keep the ceiling cooler in the summer, and prevent moisture buildup in the winter.

They were kind of difficult to install, due to the 45 degree bend at the bottom, to meet up with the vertical bird board vent holes.  We tried a couple of different installation methods, and settled on just a gradual bend toward the bottom, rather than a sharp bend.

A surprise for me was that I only used 2×6 lumber for the ceiling rafters.  I had thought that I used 2×8’s there to allow for more insulation in the ceiling, but on measuring it, found only 5-1/2″ of space.  That was a disappointment, and forced us to go with insulation foam board, instead of bat-type insulation we had hoped to use.  That way we can get pretty good R-values still, without needing to go all the way to spray foam insulation.

We ended up buying a variety of thicknesses of R-Max polyiso foam insulation boards from Home Depot.  The 2″ thick insulation had an R-value of R-13.1, with 1″ thick providing R-6, and the 1/2″ providing R-3.2.

Note: These need to be strapped down really well, with plywood or cardboard covering a good bit of the top front.  On the way home from Home Depot, we had the 1/2″ thick foam boards on the top, and a couple of them snapped off a foot or two off the end.  So when we prepared for the trip to the ranch, we covered the front with a tarp, to prevent the wind from getting under them.  This worked fine for us.

We packed as much of the foam insulation board as would fit into the rafter bays, usually 4-1/2″ total.  Some of the bays had structural items that prevented the full 4-1/2″, and ended up with about 3″ in some spots, for a foot or so.

So I estimate our average R-value to be around R-26 or so in the ceiling.  Most of it will be closer to R-30, and some only R-16 to R-20. I wish I could fit more, but I was unwilling to spend the extra time and money to fir out the rafter bays and add more.  It will just have to do.

We used some short pieces of 1/2″ plywood to hold the panels in place until we get the rest of the job done.  We found that a couple of panels were falling down while we were pounding on other panels to get them into place, and the plywood pieces kept them in place for us.

Once all of the bays were filled with insulation foam board, we went back and filled in the cracks and voids with “Great Stuff” spray foam from the cans.  I don’t know where they got that name, but it is definitely not Great Stuff!  It was very messy and hard to deal with.  But we got through it, and feel pretty good about the ceiling insulation at this point.

Next, we will add vapor barrier to the underside of the insulation, to be followed with a sort of ship lap type covering.

Stay tuned for more…
