If the attic joists are not adequate one way to strengthen the floor for live loads is to sister the old joists.
Is my header 2x6 in the attic.
I also put an attic in the back 2 3 of the garage.
Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation.
Because i was the only one in the attic this is a great two person job so the person holding the ladder steady can also fetch additional tools and cut the 2 x 6 for the new header to size when it gets to that step and the person in the attic isn t going up and down the ladder a billion times and using my new favorite tool isn t something.
This header must carry x pounds per lineal foot.
This translation is the key to any structural sizing.
Find your zone on the map and then use the chart to determine the level of insulation you need to properly insulate your attic walls floors and crawlspaces.
Add up all the loads acting on a header or beam and then translate this load into terms of how much load each lineal foot of header or beam will feel.
The attic has 2 by 8 s also but it has a plywood floor hatch and a plasterboard ceiling.
In the case of 2x6 joists you can pair them up with additional 2x6 joists by nailing them together side by side.
I have a shopsmith in my garage but only use it in the summer.
In beam speak you say.
But you can still double the capacity of the existing 2x6s in the attic floor so first let s make sure that s enough for your situation.
The vents let air flow into the rafter bays where it travels up along the underside of the roof and out through exhaust vents near the roof peak.
The first step is the same for sawn and engineered wood materials.
My son was in a power wheelchair so i built a new workbench out of the old bases and built a wheelchair ramp in my garage.
This airflow helps keep the roof deck the structural layer under the shingles.
