INSTALL GUIDES: Ceilings

Use: 10M, Prodex 48 Inch, Fast Action, 62 Inch Fast Action, 72 Inch, White, 24 Inch, 16 Inch, Rustic, Reflective Bubble Reflective, or Foil Fiberglass Vinyl

Equipment checklist: Reflective tape, double sided tape, utility knife and staples or screws - Refer to application.

Ceiling insulation is one of the most cost effective ways of controlling the outside elements. All of the reflective ceiling insulations listed above will reduce the amount of radiant heat that enters the home or building in summer by up to 97% while providing winter thermal protection. Using this insulation type will reduce the amount of energy required to heat and cool your home. This can also allow you to run your heating and cooling systems less making them last longer. It will also reduce the HVAC equipment size required thereby saving more money. Prodex Total adds R-value, radiant, vapor and air barrier - All in one product.

How To Insulate A Ceiling

Installing Insulation Over Stud: 

  1. Staple or screw to affix insulation to before installing your studs.
  2. To improve performance, let insulation sag to create air-gap (2+ inches).
  3. Tape seams with reflective tape or use Prodex Fast Action or 10M to avoid seam tape.

Installing Two Layers of Insulation Over/Under Stud:  

  1. Staple or screw to affix insulation before installing your studs.
  2. To improve performance, let insulation sag to create air-gap (2+ inches).
  3. Tape seams with reflective tape or use Prodex Fast Action or 10M to avoid seam tape.
  4. Screw 2nd layer of insulation to underside of stud.

Installing One OR Two Layers of Insulation (One Layer Between and or One Layer Under Studs): 

  1. Depending on your stud spacing, staple or screw one layer of Prodex 24 Inch or 16 Inch insulation between studs.
  2. Screw or staple larger roll (Prodex 48 Inch, Fast Action, 62 Inch Fast Action, 10M, 72 Inch, White or Rustic) under stud (Optional)

Drywall -  No Problem :) If you wish to add drywall. Attach it to the underside of your stud as if the insulation were not there. The Prodex Total roll will smash between the drywall and the stud.

Why Choose Prodex Total Over Other Ceiling Insulation Options?


When it comes to how to insulate a ceiling, choosing the right insulation material is crucial for energy efficiency, durability, and ease of installation. While traditional options like fiberglass, rigid board, and spray foam have their advantages, Prodex Total Insulation outperforms them in nearly every category. Here’s why:


Prodex Total vs. Fiberglass Insulation


FeatureProdex TotalFiberglass
Moisture Resistance100% moisture-proof – No mold or mildew riskAbsorbs moisture, leading to mold growth
R-Value StabilityMaintains high performance over timeLoses effectiveness when exposed to humidity
Air SealCreates a complete radiant barrierAllows air infiltration, reducing efficiency
InstallationLightweight, flexible, and easy to installRequires protective gear due to airborne fibers
DurabilityTear-resistant, lasts a lifetimeProne to sagging and degradation

Why Prodex is Better: Unlike fiberglass, which can trap moisture and degrade over time, Prodex Total is a vapor barrier that prevents mold and condensation. It also provides superior thermal protection without itchy fibers.


Prodex Total vs. Rigid Board Insulation


FeatureProdex TotalRigid Board
VersatilityWorks for all ceiling types, including metal and woodCan be difficult to cut and fit
FlexibilityBends and adjusts to any surfaceStiff and can leave gaps
Moisture ResistanceCompletely waterproofCan trap moisture between panels
Installation TimeQuick and easy – no adhesives requiredRequires precise cutting and sealing

Why Prodex is Better: Unlike rigid board insulation, which can be brittle and prone to breakage during installation, Prodex Total is flexible and tear-resistant, allowing for seamless coverage without the need for precise cutting or complex sealing. This makes it a more reliable and easier-to-install option for insulating a ceiling.


Prodex Total vs. Spray Foam Insulation


FeatureProdex TotalSpray Foam
Cost-EffectivenessAffordable and provides multi-layer protectionExpensive, requiring professional installation
InstallationDIY-friendly, no special equipment neededRequires specialized equipment and expertise
ToxicityNon-toxic, safe to handleReleases harmful chemicals during application
Long-Term PerformanceDoesn't shrink or degrade over timeCan crack, leading to air leaks

Why Prodex is Better: While spray foam provides initial air sealing benefits, it shrinks and cracks over time, reducing effectiveness. Prodex remains intact and maintains insulation performance for a lifetime, without requiring expensive professional installation.
