Dawnray 4" Vapor Barrier for Slim LED Downlight (Air Tight & Moisture Protection)

Dawnray 4" Vapor Barrier is designed to create an airtight seal around recessed slim LED downlights, preventing air leakage and moisture buildup in insulated ceilings.

This is an essential accessory for installations in Canada, where temperature differences between indoor and attic spaces can cause condensation, leading to mold, heat loss, and long-term ceiling damage.

Key Features

  • Airtight Protection: Prevents warm air from leaking into attic space
  • Moisture Control: Reduces condensation and mold risk
  • Energy Efficient: Helps maintain indoor temperature and reduce heat loss
  • Designed for 4" Slim Lights: Perfect fit for 4-inch recessed LED panels
  • Easy Installation: Quick install during or after drywall
  • IC Ceiling Compatible: Suitable for insulated ceilings

Specifications

  • Size: 4 inch
  • Material: Flexible PVC / Polyethylene
  • Application: Insulated ceiling / attic space
  • Compatibility: 4" slim LED recessed lights

Applications

  • Residential homes (Ontario / Canada climate)
  • Basements and upper floors
  • Attic-insulated ceilings
  • Energy-efficient building projects

Why You Need a Vapor Barrier

Without a vapor barrier, warm indoor air can escape into colder attic spaces, creating condensation. Over time, this may lead to mold growth, insulation damage, and energy loss.

How It Works

1. Install barrier over recessed light opening
2. Seal around fixture
3. Prevent airflow between conditioned and unconditioned spaces

Important Note

Recommended for use in insulated ceilings. May not be required for open ceilings or non-insulated installations.
