3" PELLET ATTIC INSULATION SHIELD VOP0300

A firestop is required at every floor and ceiling penetration to prevent combustibles from contacting the pipe at the joist level, while an attic insulation shield is specifically required when the vent passes through an insulated attic space. The shield extends upward from the attic floor (where a firestop would be installed) through the full depth of the insulation to prevent loose-fill, blown-in, or batt insulation from surrounding the pipe. In an insulated attic installation, you need both: a firestop at the ceiling level and an attic insulation shield extending through the insulation layer.

Measure the total depth of insulation in your attic from the top of the ceiling joists to the top of the insulation layer. The VOP0300 adjusts from 12.5 to 23.5 inches to accommodate various insulation depths required by modern energy codes. If your insulation depth falls within this range, the shield can be adjusted to extend just above the insulation level. For insulation deeper than 23.5 inches, you may need to construct a custom enclosure maintaining 1-inch clearance, or contact the manufacturer for guidance on very deep insulation applications.

While it's always easier to install the attic insulation shield before adding or replacing insulation, it can be installed in an existing insulated attic with some effort. You'll need to carefully move insulation away from the vent pipe area, install the shield around the pipe and secure it to the joist level, adjust it to the proper height, and then carefully replace the insulation around (but not touching) the shield. Always wear proper protective equipment including respirator, gloves, and protective clothing when working with insulation materials.

Loose-fill and blown-in insulation will naturally settle and shift over time due to vibration, air movement, temperature changes, and gravity. Without a physical barrier like an attic insulation shield, insulation will inevitably migrate toward and potentially contact the vent pipe, creating a serious fire hazard. Additionally, building codes specifically require proper shields or enclosures - manual separation is not compliant with safety regulations and will not pass building inspection.

The VOP0300 maintains a minimum 1-inch air space clearance from the outer wall of the vent pipe to the inner surface of the shield. This clearance is mandated by both U.S. (NFPA 211) and Canadian (CSA B365) building codes and must be maintained throughout the entire vertical height of the shield. The shield itself then keeps all insulation material outside of this protected zone, ensuring safe operation at all times.

No, the attic insulation shield is only required when the pellet vent pipe passes through an insulated attic space. If your attic is completely uninsulated (no insulation present), you only need the appropriate firestop at the ceiling penetration point. However, if you plan to add insulation to your attic in the future (which is recommended for energy efficiency), you should install the shield at that time to maintain proper clearances and code compliance.

The attic insulation shield is primarily designed for loose-fill, blown-in, and batt insulation that can be kept away from the shield's exterior surface. Spray foam insulation presents unique challenges because it adheres to surfaces and cannot maintain an air gap. If you're planning spray foam insulation in your attic, consult with both your insulation contractor and a qualified pellet vent professional before proceeding, as special considerations and alternative methods may be required to maintain proper clearances while achieving effective insulation.

The VOP0300 is covered under the manufacturer's limited lifetime warranty program, typically providing 100% replacement coverage for 15 years from the original purchase date, then 50% coverage thereafter. Warranty coverage requires professional installation according to manufacturer specifications, proper annual system maintenance, burning only approved fuels, and keeping proof of purchase and product registration. Note that labor and installation costs are not included in warranty coverage. Always register your product promptly and retain all documentation for warranty claims.
