Edmonton's R Value: 0.80
The R value, also known as the reproduction number, describes whether COVID-19 cases are currently increasing, decreasing or staying the same. It tells us average number of people that someone with COVID-19 will infect.
Newly built house open to the public for Sustainable House Day. Rated at 6.5 star. It is oriented to minimise solar heat-gain in the mornings and evenings, and to maximise natural ventilation from the breezes flowing up and down the Redlynch Valley. The eaves are 600 cm wide. the glass is grey tinted and the walls and roof have R3 insulation. Ceiling fans are installed throughout.
Fiberglass has been the standard for home insulation. Now polyurethane or cellulose foam spray is getting a lot of play--particularly when we renovate.
Oddly, foam has the same R-value (heat transfer resistance) as fiberglass. Also, it's significantly more expensive. So why are we recommending it? Because it works much, much better. It cuts your utility bills. And you can get a $1500 tax credit for using it.
Foam insulation expands on contact as it is installed and, because of that, creates a very tight air seal inside wall cavities. It fills in all the joints, crevices and areas where pipes and wiring pass through. So the effective R-value of foam insulation performs at a much higher level due this air sealing property. Heat can't sneak around the insulation barrier on air currents as the building "breathes".
we aren't fond of plastic - but we get the best rvalue for the buck out of this - and it's far less harmful than lots of products out there. also - the rigid foam provides great indoor air quality (no alergens) and it's backed w/ a radiant barrier on both sides. this product is made to go accross the studs - but we've used it between (due to our sheerwall issues) and we've sealked it with a two part blow in foam - so that we have an airtight envelope. we'll need practially no heating and we won't be installing air conditioning - evenhere in sunny so. california.
With my stopover in Eugene my daughter took me to a construction site were her friends were building a straw bale house. Straw bale construction is a building method that uses bales of straw as structural elements, building insulation, or both. With a reported R-value ranges from 17-55 this method is very interesting.

No marking needed, just stick the blade where the cut starts. It's foam, not furniture so think "carpentry" not "cabinetry" as far as accuracy goes.

I shoved each panel up under the top lip of the door section so that I had about .25-.50 inch of overlap on the bottom.
Vertical measurement with the top of the tape as far up into the door lip as it would go.
I cut off a strip of foam board to experiment with the width and for my door and 1-inch foam it worked out well to cut it to 19.5 inches.
After this house changed hands a few months ago the current residents have made some changes. First came a HVAC service company. Today it is a contractor bringing insulation materials to improve the R-value (resistance to temperature conduction) so the house uses less electricity to cool or to heat the interior, no matter how extreme the ambient air temperature in summer or winter.

Horizontal measurement, to the nearest 1/8 inch was accurate enough. Of the four sections of my 16-foot door, I had to cut panels to three different widths. So measure each section.
Line up the drywall square and cut. I like to cut on the far side of the rule so I never have to cross my off hand with the knife.
There are many wall insulation types to choose from on the market today and it’s not always easy to know which one to buy. It often comes down to the reason you are insulating your home in the first place. What are you trying to achieve? Are you after thermal benefits or are you aiming to reduce the transfer of sound? One thing you should know, however, is that the thermal benefits will be the same for any bulk insulation with the same R-value. #wall #insulation #thermal #sound #bulk #rvalue #pink #batts #earthwool #knauf #roof #underfloor #glasswool #firmer #odourless

Insulation is measured or rated in terms of its thermal resistance, or R-value. The higher the R-value, the greater the effectiveness of the insulation. The R-value depends on the type of insulation, its thickness, and its density. The greater your R-value, the greater your resistance to heat flow and loss. Its effectiveness also depends on how and where the insulation is installed. If your insulation is compressed it will not provide the full R-value.
There are different R-values based on what might be required for your climate (R-13 for warmer climates and R-30 for colder climates; and for different sized areas (16" spaced studs or joists, vs. 24" spaced ones; and for different applications - if your walls are 2x4, vs 2x6 or even 2x8 construction for example).
We are required to have R-21 in our 2x6 walls, R-38 in our vaulted ceiling and R-30 under our floors per our building code.

Pull the manual disconnect to disengage the garage door opener because you will be running the door up and down a lot.
I broke this one putting it in. I was trying to get a picture to show how far it will flex and I went a little too far. I moved this one to the spot behind the lock bar and the break is not visible. I also could have put a strip of tape across the break.
