LP® TechShield® Radiant Barrier Installation Problems to Avoid in Cathedral or Vaulted Ceiling Designs

Recently, homes are trending toward smaller, more compact sizes. Using extra-tall, cathedral or vaulted ceilings can create the illusion of a larger living space. But how do you avoid installation problems when insulating a cathedral or vaulted ceiling? How do you avoid problems when insulating an open ceiling? 

With little or no attic space over these living areas, a bit of planning is required to avoid potential pitfalls when constructing the framing and building envelope as well as positioning HVAC and insulation. Regardless of ceiling design, insulation helps optimize the home’s energy efficiency. A radiant barrier, such as LP® TechShield® Radiant Barrier sheathing, can be an important element of your insulation plan.

Using LP® TechShield® Radiant Barrier for Impressive Energy Efficiency

Building with LP TechShield Radiant Barrier is proven to help block up to 97% of radiant heat transferring through the panel. This can help reduce attic temperatures by up to 30° F. 

Constructing cathedral, vaulted or even open ceiling designs below LP TechShield Radiant Barrier sheathing requires a few installation tips to maximize its effectiveness. Don’t forget to review the complete installation instructions before beginning. 

#1**:** Always install LP TechShield panels with the foil side down and the skid-resistant side with the APA trademarks facing up.

#2: Maintain a minimum of ¾-inch air space below LP TechShield and any other material, including drywall, finished wood or insulation. This ¾-inch air gap allows the radiant barrier to work

#3: With no conventional attic, it’s critical to install soffit vents to ensure proper ventilation. Regardless of ceiling design, always comply with your local building codes regarding ventilation requirements. 

#4:  If you’re planning on an open or exposed ceiling design—for example in a loft space or garage or shed—do not paint the LP TechShield Radiant Barrier sheathing. The aluminum foil-like overlay allows the radiant barrier to work while the VaporVents™ technology allows the panel to breathe and lets moisture escape.

With proper LP TechShield Radiant Barrier installation, both you and your clients may enjoy two decades of peace-of-mind protection with its 20-Year Transferable Limited Warranty, not to mention the lasting benefits for the life of the home. 

Fire-rated sheathing is also important for smaller homes. If you’re building smaller single-family houses today, be sure to see why LP® FlameBlock® Fire-Rated Sheathing is the perfect fit for today’s smaller homes.
