Hurricane ties and sealing top plate
Does anyone have a good technique for sealing the ceiling plane air barrier to the top plate when using scissor trusses and hurricane ties? We will have a sloped ceiling with a 2.5/12 pitch and a vented roof assembly.
One of my questions is how to get a good seal around the all of the hurricane ties without a lot of fuss. The most commonly used tie here is the Simpson H1 tie. Some here have suggested using the truss screws instead, but the lateral strength is a lot lower. We are a high wind and earthquake zone near Seattle.
I’m sure others have dealt with this and perhaps it is as simple as using more sealant or thicker gasket but I thought I’d check to see if there was a more elegant approach. It seems like some sort of flashing or backing at that joint would help a lot to give something more substantial to seal to, hurricane ties not withstanding.
