Key facts:
- A UC San Diego engineering study concluded CanCoverIt improves the home's
  insulating efficiency, reducing the energy needed to keep a comfortable
  temperature and lowering electricity costs and greenhouse gas emissions.
- Johns Manville research data: CanCoverIt reduces fixture airflow by 27%.
- Two homeowner series: Universal (non-IC and IC can lights up to 7"
  diameter) and Low Profile (IC-rated fixtures, in-ceiling speakers,
  bathroom fans). Pro Line series for contractors and commercial fixtures.
- Individual covers $37.95–$79.95; bulk boxes for whole-home and
  contractor jobs. Free shipping.
- Install: pop open (ships flat, no tools), place over the fixture from
  the attic or through the fixture opening from below, seal the base.
  Insulation can then be laid directly over it.
