How to pass a QII insulation inspection the first time如何一次通过 QII 保温检查
QII is not a test you can pass by measuring after the fact — it is a visual verification of installation quality that has to be right before the drywall goes up. Most failures are avoidable at the framing and insulation stages, not at inspection.QII 不是事后测量就能通过的测试——它是对安装质量的目视核验,必须在石膏板上墙前就做到位。多数不合格在框架与保温阶段即可避免,而非等到检查时。
What the rater is checking评级员在核查什么
Quality Insulation Installation verifies that insulation was installed to the cleanliness and alignment conditions the Energy Code specifies — full coverage with no gaps, voids, compression or misalignment, with the air barrier and vapor retarder correctly placed and sealed. The rater is not grading R-value from a label; they are confirming the installed assembly matches the assembly the compliance report claimed credit for.QII 核查保温是否按能源规范规定的洁净与对齐条件安装——覆盖完整,无空隙、空腔、压缩或错位,气密层与防潮层位置正确并密封。评级员不是按标签评定 R 值,而是确认实际安装的构造与合规报告申报取分的构造一致。
That is why the same insulation product can pass on one job and fail on the next: the failure is usually workmanship — batts stuffed around wiring, gaps at the plate line, insulation pushed behind outlets, or a vapor retarder lapped the wrong way — not the material.这也是同一款保温材料在这项工程通过、在下项工程却不合格的原因:问题通常是工艺——玻璃棉被塞在电线周围、板线处留有缝隙、保温被推到插座背后,或防潮层搭接方向错误——而非材料本身。
The most common causes of a re-inspection最常见的复检原因
The recurring failures are predictable: incomplete coverage at rim joists and attic knees; compressed batts behind blocking and in tight stud bays; gaps where wiring, plumbing and ductwork pass through; missing or mis-sealed vapor retarder at penetrations and laps; and insulation installed before the cavity was cleaned of debris. Each is visible to the rater and each is fixable in minutes — if the cavity is still open.反复出现的缺陷是可预见的:边缘托梁与阁楼斜梁处覆盖不全;砌块背后与狭窄龙骨腔内玻璃棉被压缩;电线、管道与风管穿过的位置留有缝隙;穿透处与搭接处防潮层缺失或密封不当;以及空腔未清理干净就安装保温。每一项评级员都看得见,也都能在几分钟内修好——前提是空腔仍敞开。
A pre-drywall checklist that prevents it避免问题的封板前清单
Before calling for QII: confirm the insulation type and R-value match the CF-1R for every assembly; walk the envelope for coverage and compression; verify the vapor retarder is continuous, correctly oriented and sealed at penetrations and laps; confirm attic and crawlspace insulation is not blocking required ventilation; and photograph each assembly. A rater who can see the work clearly, with the documents in hand, is far less likely to flag a stage.在申请 QII 前:确认每种构造的保温类型与 R 值与 CF-1R 一致;巡查围护结构的覆盖与压缩情况;核实防潮层连续、方向正确,并在穿透处与搭接处密封;确认阁楼与爬行空间保温未堵塞所需的通风;为每种构造拍照。文件齐备、施工清晰可见时,评级员标记问题的可能性要低得多。
Book the QII visit for the window between insulation complete and drywall hung. That window is short on a fast ADU or addition schedule — it is the single most common reason a project ends up opening walls it had already closed.将 QII 到访安排在保温完成、石膏板未挂的窗口期。在进度较快的 ADU 或扩建工程中,这个窗口很短——这正是工程被迫重新开墙的最常见原因。
