PrimaLoft introduces most technical insulation ever

The first thing to keep in mind is that primaloft has never been an acceptable insulation, in my opinion. They are a joke!!!

Insulation specialist PrimaLoft has developed a new range, UltraPeak, presented as the warmest insulation it has ever made. [Having looked at the picture of this new insulation I can see why they say it is the warmest they have ever made. It is about 6 layers thick so it would be better insulation than all of their previous one-layer products.]

 The high loft and super soft filler is made from a blend of “architectural” fibres and microfibres that create a “scaffolding effect” that traps more air and thus increases the insulation’s thermal performance by 5%, the company said. 

[I have never heard of the term “architectural” used to describe chopped staple fibers. The blend is probably a 4 or 5 denier fiber blended with their micro fibers and they are making a garneted batting and layering as I said about 6 layers which causes them to describe it as “scaffolding effect” and ultimately the thickness will trap more air but 5% is a stretch.

The new reference is made from 100% recycled polyester (from bottles), and produced using PrimaLoft’s lower impact P.U.R.E. process. UltraPeak comes in the form of batting, a shift away from the current trend for loose fill solutions. Batting is generally easier to use and allows for greater manufacturing efficiency, the company said. 

Once you melt down all of the polyester bottles and recycle it back into polyester fiber it is no different than virgin polyester fiber. Therefore, the new polyester batting they are making will work as virgin polyester batting works. Unbonded polyester [loose fill] is useless. And yes bonded batting is easier to work with. What they are leaving out is the method by which you use the bonded batting, QUILTING. Once you quilt the batting you reduce the thickness of the batting, hence the air spaces which reduces the insulation.

The way I see it is that primaloft geniuses who are woefully deficient in insulating materials are probably losing business to companies using waste fiberfill products that are considerably cheaper. This company is not “insulation specialists”. But they keep trying.
