Note: Installation instructions and illustrated drawings are recommendations only, while proper local construction methods are the responsibility of the installer.

When considering options for a crawl space, Reflectix® Reflective/Bubble product is the easiest (to handle) choice available. It comes in convenient roll sizes that install cleanly and quickly. The product is dust and fiber-free, and does not require any protective garments or respirators to work with.

Product Description

The Reflectix® Double Reflective Insulation consists of two layers of highly reflective film (94%+ reflectivity) that are bonded to two tough layers of polyethylene. Two inner layers of insulating bubbles and a center layer of polyethylene provide this easy to handle product with high strength and reliability.

Installation Instructions

Note: This product is reflective on both sides and the direction of product installation is not pertinent to thermal performance.

Note: For this application it is recommended to use at least 3/8 inch staples that are Heavy Duty or Galvanized.

  • Inspect the crawl space and make any needed repairs before installing the Reflectix® Double Reflective Insulation.
  • Check the crawl space to determine whether the floor joists are 16” or 24” on-center.
  • Determine if there are water pipes and heating ducts which hang below the floor joists. They will need to be insulated. Reflectix® Pipe Wrap and Duct Insulations are designed specifically for this use. There is no need to wrap water pipes or duct work that fall between floor joists. Reflectix® will provide adequate insulating without extra wrapping.
  • Start at the end of the house and face staple to the bottom of the floor joists. Seal seams with Reflectix® Foil Tape to create a vapor barrier. At the end, staple up to the sub-floor or band board.
  • Note: Existing mass insulation in the joist cavities must be dry prior to installing the Reflectix® product.

Important

Review These Important Safety Guidelines Prior to Installation:

  • ALWAYS check local building codes before installing Reflectix®.
  • ALWAYS check the area you are insulating and make any needed repairs. Any worn wiring should be replaced before you begin installing Reflectix®.
  • ALWAYS make sure work areas are well ventilated and well lighted.
  • ALWAYS use eye protection when operating a staple gun.
  • ALWAYS use caution and common sense when using a staple gun. Be aware of electrical wiring locations. Stapling into a wire can cause severe shock or death. NEVER staple into electrical wiring.
  • ALWAYS be careful when working with large pieces of Reflectix® on windy days.
  • When installing Reflectix® on bright sunny days, it is best to wear sun glasses.
  • Do not work in areas such as attics when temperatures are too hot.
  • Please Note: The intention of these Installation Instructions and 3-D renderings are for the sole purpose of illustrating the correct location and relative position of the Reflectix® products in specific building assemblies. The correct construction methods and techniques are the responsibility of the installer or contractor. The methods outlined are recommendations on location of the Reflectix® products as a guideline. There are no claims on the part of Reflectix, Inc. that these building assemblies are finite standards or meet building code requirements (as they can vary by region).
