    Abstract: A method of retrofitting a building exterior with an insulation and cladding construction has a multitude of steps. One step involves placing rigid panel insulation members to certain areas of the building exterior. A subsequent step involves spraying polyurethane insulation foam to certain areas of the building exterior. And yet another step involves spraying cladding over the rigid panel insulation members placed at the building exterior, and involves spraying the cladding over the previously-sprayed polyurethane insulation foam. The sprayed cladding cures in-place and, once cured, constitutes a continuous and monolithic cladding exterior construction over the placed rigid panel insulation members and over the sprayed polyurethane insulation foam.

    Abstract: A method for producing a bonded magnet, comprising: (i) low-shear compounding of a thermoplastic polymer and magnetic particles to form an initial homogeneous mixture thereof; (ii) feeding the initial homogeneous mixture into a plasticator comprising a low-shear single screw rotating unidirectionally toward a die orifice and housed within a heated barrel to result in heating of the initial homogeneous mixture until the thermoplastic polymer melts and forms a further homogeneous mixture, wherein said further homogeneous mixture is transported within threads of the single screw towards the die orifice and exits the die orifice as a solid pellet; (iii) conveying the solid pellet into a mold and compression molding the pellet in the mold, to form the bonded magnet, wherein the bonded magnet possesses a magnetic particle loading of at least 80 vol % and exhibits one or more magnetic properties varying by less than 5% throughout the bonded magnet.
