epsilonGreedy Posted September 22, 2020 Share Posted September 22, 2020 Treated/Untreated C16 or C24 Rough sawn so it grips the mortar bedding or just normal smooth wood I am also getting mixed messages on the thickness. Local trades assume 50mm is fine whereas technical resources indicate it should be 75mm thick. My wall plate is supporting trusses as 600mm centers, the inner wall blocks are fibolites (heavy end of light) and the roof cover is natural slate.

My trusses sit on the inner block wall so in theory the wall plate seat should be dry. Boxed eaves should help as well. Link to comment Share on other sites More sharing options...
