Ontario-based company gets patent for plastic insulation process

Recycled-PET product to compete with glass-fibre, cellulose

Rtica Corporation (Stoney Creek, ON) was recently granted a patent for a method of blowing polymer filaments through an arrangement of alternating slots. The method is the primary proprietary process by which Rtica converts and manufactures recycled PET into Rtica brand insulation.

Rtica PET insulation is manufactured and sold in an unexpanded form of blowing wool called Rbuds. In this form, the insulation is 30% more dense than glass-fibre and 69% more dense than cellulose. Because of the its higher density, Rbuds reduces warehousing costs. Contractors require approved expansion equipment to install Rbuds.

Polyester fibrefill has been used for years as an insulating material in outdoor clothing. Commercial distribution of Rbuds is currently limited to installation contractors in the Southeastern United States. The company is planning to build an additional manufacturing facility in 2004 and eventually extend commercial distribution of Rtica insulation to other regions of North America, according to a company spokeman.
