MFM SubSeal40 Waterproof House Wrap
MFM SubSeal40 is designed for moisture-prone applications with a balance of strength and flexibility. The membrane contracts and expands with the building surface, reducing the risk of tearing during temperature cycles. The outer film surface is compatible with most construction sealants, simplifying flashing and joint work. It is particularly suitable for below-grade foundations and other areas where extreme moisture protection is needed.
- High strength with improved elongation for movement
- Outer film compatible with common sealants
- Designed for extreme moisture protection
- Suitable for below-grade foundations and structures
MFM SubSeal60 Waterproof House Wrap
The SubSeal60 option offers higher mil thickness for enhanced durability and moisture resistance. It maintains high elongation, allowing the membrane to contract and expand with the surface of the building. The outer film is compatible with most construction sealants, supporting straightforward installation and reliable performance in environments with elevated moisture exposure.
- 60 mil thickness for added protection
- Continued high elongation to match surface movement
- Sealant-friendly outer film
- Specially formulated for extreme moisture conditions
Prime Wrap PR-4575 House Wrap
Prime Wrap PR-4575 is designed for exact sizing and building-code compliance. The product is shipped in a 4.5-foot tube, and to reach a 9-foot length you unfold it after unwrapping. It’s engineered to meet standards and codes, providing safer use for home improvements while reducing air transfer through walls. This helps insulation perform as intended and supports stable indoor temperatures through varying seasons.
- Unfolds to reach full length from a compact tube
- Meets national building codes and standards
- Blocks air transfer to reduce heating and cooling loads
- Supports effective insulation performance
ATack Construction Seaming Tape Red
ATack Red Seaming Tape is a heavy-duty, waterproof pressure-sensitive tape designed for sealing vapor barriers, house wrap film, foam insulation boards, and joints. It is engineered for long-term sealing of seaming and sheathing materials, providing up to 15 years of reliability. The tape avoids lengthwise splitting and uses an industrial-grade backing to prevent curling, making installation faster and more dependable.
- Heavy-duty, waterproof construction tape
- Prevents midroll splits and curling
- Extra sticky acrylic adhesive bonds to diverse surfaces
NASA TECH Radiant Barrier Solid White Wrap
NASA TECH Commercial Grade Solid White Radiant Barrier Wrap is designed as a radiative heat barrier with no perforations. It reflects heat effectively while functioning as a house wrap in retrofit and new construction projects. The product claims to block a large portion of radiant heat, which can contribute to lower cooling loads and improved indoor comfort during hot summers and cold winters.
- Non perforated solid white radiant barrier
- Reflects up to 97% of radiant heat in some conditions
- Versatile use in retrofit and new construction
- 4 ft wide roll, 100 sq ft coverage
Buying Guide
Key purchase considerations
Climate and moisture exposure largely determine the right wrap. Coastal or wet climates benefit from thicker membranes with robust moisture resistance, while standard residential applications may perform well with mid-range options. Wall type and framing affect installation; some wraps are better suited to below-grade exposure or retrofit work. Thickness (mil) and permeability influence air leakage control and vapor management. Compatibility with sealants, tapes, and flashing materials is essential to ensure durable seams and long-term performance.
Material characteristics and uses
From 40 mil to 60 mil wraps, thickness correlates with durability, puncture resistance, and wind-driven rain performance. Thicker wraps generally offer higher protection but may require specialized installation approaches. Radiant barrier wraps add energy-saving benefits by reflecting solar heat, but they are not always necessary for moisture control. Seaming tapes from ATack provide strong seam sealing without tearing or curling, which is critical for maintaining a continuous vapor barrier. In areas with high moisture or below-grade exposure, prioritize membranes designed for extreme moisture protection.
Installation considerations
Follow manufacturer guidelines for overlap, flashing, and sealing at corners and joints. Use compatible sealants and tapes to avoid chemical incompatibilities that can degrade the wrap. Ensure surfaces are clean and dry before installation, and avoid stretching or tearing during application. For retrofits, consider a combination approach: a moisture-resistant wrap paired with a high-quality seaming tape to create a continuous barrier that resists air infiltration and moisture ingress. Proper ventilation and vapor management should align with local building codes.
Comparing the five options
| Feature | MFM SubSeal40 | MFM SubSeal60 | Prime Wrap PR-4575 | ATack Tape | NASA TECH Radiant Barrier |
|---|---|---|---|---|---|
| Primary use | Moisture barrier | Moisture barrier | Code-compliant wrap | Sealing joints | Radiant barrier / wrap |
| Thickness | 40 mil | 60 mil | Not a single thickness spec; length-based | N/A | Not a perforated wrap |
| Installation note | Flexible with sealants | Same, higher durability | Unfold to required length | Strong seam adhesion | Energy barrier component |
| Code/standards | Extreme moisture ready | Extreme moisture ready | Meets codes | Long-term seal | Reflective barrier claims |
In choosing among these options, consider whether your primary goal is moisture protection, air leakage reduction, or radiant heat management. For typical exterior walls in wet climates, a robust moisture barrier like SubSeal40 or SubSeal60 paired with high-quality seaming tape often yields the best all-around performance. If energy savings are a strong priority, a radiant barrier option can be advantageous, provided it complements, rather than replaces, the moisture barrier. Always confirm compatibility with local building codes and installation practices before purchasing.
