House Wrap Insulation
Stop Energy Loss at the Walls – Where It Begins
Reduce energy loss and improve indoor comfort with Energy Shield® reflective house wrap insulation, engineered for high-performance wall assemblies. Our radiant barrier house wrap improves energy efficiency by reflecting heat and protecting exterior walls from moisture intrusion. Ideal for residential and commercial wall systems, this energy-efficient wall insulation improves exterior wall performance and delivers long-lasting performance in all climates.
Reflective house wrap improves energy efficiency by reflecting heat and controlling moisture. Ideal for residential and commercial wall insulation, it delivers year-round comfort and long-lasting performance.
Block Radiant Heat
Radiant barrier house wrap prevents solar heat from penetrating walls, keeping interiors cooler in summer and warmer in winter. By reflecting heat before it enters the wall cavity, Energy Shield® improves comfort and reduces HVAC demand.
Stop Moisture & Condensation
Reflective house wrap controls moisture, protecting wall studs, sheathing, and insulation from condensation and mold growth. Proper installation ensures long-term durability and maintains energy-efficient performance.
Save Energy & Money
Energy-efficient wall insulation reduces heating and cooling costs. Reflective house wrap lowers energy demand, increases efficiency, and improves indoor comfort year-round.
Why Exterior Walls Need House Wrap Insulation
Walls are the largest surface exposed to heat gain in summer and heat loss in winter. Without proper house wrap insulation, radiant heat enters during summer and escapes during winter, forcing HVAC systems to work harder.
or complete building envelope performance, exterior wall insulation should work alongside radiant barrier roofing insulation to reduce heat transfer from above, while basement insulation helps reduce heat loss and moisture from below.
How Reflective House Wrap Insulation Works
Reflective house wrap insulation works by using a low-emissivity surface to reflect radiant heat away from exterior wall assemblies. Traditional insulation slows heat transfer through conduction, but radiant barrier house wrap reflects solar radiation before it enters the wall cavity. When installed behind exterior siding with an air space, the reflective surface redirects heat away from the structure while helping control moisture movement.
This helps:
- Reduce solar heat gain through exterior walls
- Improve overall wall insulation performance
- Lower heating and cooling demand
- Maintain more stable indoor temperatures

House Wrap Insulation FAQs
House wrap insulation is a reflective or radiant barrier installed on exterior walls to reduce heat gain, prevent heat loss, and protect against moisture.
Reflective house wrap reflects solar heat away from walls in summer and reduces heat loss in winter, improving energy efficiency and indoor comfort.
Yes. Properly installed radiant barrier house wrap redirects moisture, protects wall studs and sheathing, and reduces condensation and mold growth.
Yes. Exterior wall insulation, like reflective house wrap, prevents heat transfer, lowers HVAC demand, and keeps indoor temperatures stable year-round.
Absolutely. Energy Shield® house wrap insulation is ideal for both new construction and retrofit applications, providing long-lasting energy savings and wall protection.
Install house wrap insulation with continuous coverage, properly sealed seams, and a compatible vapor barrier. For radiant barrier wrap, leave a 1″ air gap to maximize efficiency.
Reflective house wrap performs best when installed with a small air space between the reflective surface and exterior siding. This air gap allows the radiant barrier to effectively reflect solar heat away from the wall assembly.
