Mechanical insulation helps protect your HVAC system and its parts. If you are installing a new system, then you can insulate it as you install it. If your current system isn't insulated, or if you need to replace old materials, then you can retrofit the insulation.
The insulation material you use makes a real difference to these systems. In many cases, elastomeric products work well here. These products combine materials such as rubber, PVC, and chemical foams to create a cushioned and highly-effective cover for essential parts.
Scrap metal is a valuable commodity, and many people want to take advantage of its worth by selling it at their local scrap metal yard. But while some types of scrap metal are easy to recycle, others can be more difficult or even impossible for the individual seller to get rid of.
Understanding why your local scrap metal yard might not accept certain items can help you make informed decisions about what types of metals you should try to sell and which ones should be avoided.
