Which of the following is NOT a type of pin used in insulating work?

• A. Nails
• B. Self sticking pins
• C. Pressure sensitive pins
• D. Anchor Pins

Answer: (A)

In insulating work the fasteners to hold insulation in place are designed to grip or adhere without damaging the material or creating gaps that let heat through. Self sticking pins rely on adhesive to attach, which lets insulation stay fixed without penetration. Pressure sensitive pins use a sticky mechanism that holds under pressure. Anchor pins are built to secure insulation by anchoring into the surface so they stay put during handling and use. Nails, by contrast, are basic metal fasteners intended for wood or masonry and they penetrate through the insulation material, can create gaps, puncture the insulating layer, and aren’t designed to hold insulation securely over time. That’s why nails aren’t considered a type of pin used in insulating work.
