Asking for a friend

Do the two beams used for the door opener serve another purpose, I would like to remove them then eliminate the door by framing it out.

 

I'm currently insulating the walls with Roxwul to R22, but thinking of using a spray on insulation for the ceiling. Your opinions and comments on the Pro's and Con's are welcome.

 

Will the foam deteriorate when exposed to chemical fumes should I decided to paint a tractor or do some electrical plating which involves the use of acids.

 

Even with using a fume hood some fumes escape.

I think we would need to see the 'big picture' to give a proper answer, and really, it's a question for a structural engineer and not someone with 'internet credentials'

 

I will say that those cross beams may be serving to tie the two opposite walls together.  Imagine a full load of snow on that roof, you can see how it would want to push the opposite walls apart.

That looks like all 'rough sawed' lumber, so they're not factory roof trusses.  I suspect it was hand built by previous owner, so those horizontal beams help support the roof as Jeff said.  You have some collar ties farther up on the rafters, but they look lightweight, and I wouldn't depend on them in a heavy Canadian snow.  If you remove them, a heavy snow load could cause the walls to buckle outward and the roof rafters to collapse.

I think you nailed it Jeff-C175

 

Possibly explain what they did with the garage on the property we occupy.

Rafters like you have were very common in early construction. It is also very common to see cross pieces added in after the fact to keep the roof from pushing out on the walls. Again just like you have. Very glad that trusses have become the normal in construction, they are a much sturdier design.

Important to note that the beams are only there to hold the walls from bulging outward from roof loading. They are in tension and are not intended to support a large load sideways beyond their own weight--in other words, don't try hanging a winch for lifting or using it as a base for a floor for storage unless you provide significant additional structural support. Even holding up the weight of the open garage door, while it seems to be working so far, would make me nervous. I would tie them to a pair of roof rafters above the opener support and maybe also on their other ends for symmetry.

In many older buildings and churches, this "wall holding" was done with iron rods or even chains!
