How should the junctions of non-loadbearing timber studinternal partition walls with timber I-joist or solid timber joist separating floors be constructed?
There are alternatives available at both the base and head of partition walls. Either of the two base treatments can be used with either of the two head treatments: 1) Internal partition walls can be constructed either; a) directly off the floating floor treatment (FFT) provided the design meets the FFT manufacturer’s instructions, including additional battens to support the internal walls if necessary, or b) installed off the floor decking, provided the 5mm (min) resilient flanking strip is correctly installed to all perimeters of the floating floor treatment to isolate the floor from all the walls and skirtings For structural reasons, loadbearing internal walls should normally be installed as per option b). 2) At the partition head, internal walls can be installed either; a) up to the ceiling lining fixed via resilient bar noggins, or b) through the ceiling lining and fixed directly to the joists, provided the head plate fully seals the void between the wall linings such that there a
