Rubio Monocoat vs. Safecoat Acrylacq for cabinets?

Hi there,

In working with a custom woodworker we are trying to build green cabinets (green from an air quality stand point). We are trying to decide on a finish for the hardwood doors of the cabinets. We were trying to sort out the differences between Safecoat Acrylacq or Vermont Natural Coatings to choose one of these.... but then.....Rubio Monocoat came to our attention.

I realize that it is a very different type of product than something like Safecoat Acrylacq (which is a water-based poly finish) -- I realize Monocoat won't have the sheen of a poly finish. I think that's OK with us.

Deciding between conventional heat pump and minisplits

I'm working with homeowners who are considering an HVAC upgrade for their new house, approximately 2,000 sq.ft. It's vintage 1970's, but we'll be doing a number of air-sealing and insulation upgrades. Eventually we'll have an HVAC design professional come check the place out, and make recommendations, but for the moment we're considering what options are out there. Currently, the house has the original forced air ductwork, with a new heat pump put in last year by previous owner. It's a Lennox XP14-042, with matching new air handler and resistance heat.

L shaped building/gable roof

I have been told that a home that is L shaped is much more expensive to build than if the extra space was just included in primary rectangle--no"L" The reason I was given is that the cost of joining the roofs is too expensive. Can someone give me an example of what the additional percentage might be? Thank you

Fully applied membrane substitute

When applying exterior insulation, the PERSIST method specs a fully adhered membrane covering the sheathing to control air, moisture and water. These self adhered membranes can be costly, so I'm wondering if there is any risk in using the peel and stick membrane where it's needed and then less expensive draining type house wrap in the field of the wall.

This might be trickier to install but right now I'm just interested in the performance of these materials - would it matter that the house is wrapped in 2 materials with very different perm ratings?

Thanks

Air sealing CMU walls that are exposed inside and out in tropical climate

I'm looking for an effective membrane and/or application to air seal a home with walls made up entirely of exposed CMU.

I'm working on the mechanical systems design and spec for the home and advising the builder to lower the infiltration so we can keep latent loads to a minimum. I am not interested in R-Value.

The 5,000 s.f. home is located on a very small private island just north of Exuma, Bahamas, and it is surrounded by ocean. The interior and exterior finish of the home is exposed CMU.

What is a building with two roofs called?

There is a current trend out there to build a roof that covers the building and the add another roof over the veranda--What is this secondary roof called. From the pictures I have seen it appears to be attached to the walls of the building with supporting posts on the veranda. It does not seem to be attached in any way to the main roof over the building's interior space. If you build one of these separate roofs can you then go and close them in at a later time?

Where shall I place my PV panels?

My new house is in the design stage. Mid-coast Maine, about 20 miles from the ocean, zone 6.

Good southern exposure. Standing seam roof, oriented about 10 degrees west of due south. 8/12 pitch.

Here's my question: Is there any benefit to placing of panels on the roof as opposed to a ground mount? I have plenty of room on the ground.

Issues from a new "flat" roof install

Hope I do a good job explaining myself here:

Early last week we had a new roof installed. The front portion of the house is your typical pitched roof (shingles) but the back portion of the house, which is a new addition (prior owners added on), required a "flat" roof system. The "newer" addition enabled prior owners to move a kitchen back there as well as a larger family room. So the flat roof system is above the kitchen and family room.

Would replacing my gable-end vents with a full ridge vent increase stack effect cooling in the attic?

My attic currently has partial soffit vents and gable end vents. It also gets extremely hot due to the harsh New Mexico sun. When I get the roof re-done, would it be worth it to add a full ridge vent to increase the rising hot air's ability to escape from the attic? Or would the effect be minimal at best, especially if I'm replacing shingles with light-colored metal?
