The present invention provides methods and apparatuses for securing safing insulation in the gap formed between a spandrel and a slab. Additionally, the present invention eliminates the need for stiffening tees and/or stiffening brackets. In one exemplary embodiment, the present invention utilizes a first portion of safing secured to spandrel insulation positioned in an exterior wall structure and a second portion of safing insulation positioned adjacent to the first portion of safing insulation and between the spandrel insulation and the slab. By fixedly securing the first portion of safing insulation to the spandrel insulation, any deformation of the spandrel insulation caused by the forces exerted by the compressed second portion of safing insulation on spandrel insulation results in the first portion of safing insulation moving with the spandrel insulation.

A Tee piece that functions as device to direct dual, alternating respiratory therapies to a patient. It has a centrally located low pressure actuated one way valve that connects the inhalation and exhalation paths to the specific therapy devices. The gravity hung valve has a low pressure activation and an offset, angled seat that allows the valve itself to be completely removed from the path of the medicated aerosol particles so as to minimize the potential for particle condensation by collision with the valve. The valve forms a holding chamber for the medicated aerosol increasing the efficiency of the nebulizer cycle. The physical design of the Tee piece's outside surface prevents reverse connection, which is a common problem and the oval shape of the PEP port eliminates blow-off of the PEP device by excessive back pressure.
