Why Magra Wool Is the Better Choice Over Spray Foam Insulation?

Natural. Breathable. Proven in the Desert.

The Hidden Risks of Spray Foam Insulation

Spray foam insulation may be marketed as airtight, efficient, and sleek—but beneath the surface, it poses serious concerns for both buildings and the people inside them. Here are some of the most pressing issues:

Mold Risk from Trapped Moisture

Spray foam, especially when not installed perfectly, creates a seal so tight that any moisture trapped behind it cannot escape. In climates with fluctuating humidity, this can lead to hidden mold growth inside walls and ceilings—unseen until it causes health issues or structural damage.

Chemical Odors & Toxicity

Spray foam is mixed on-site with reactive chemicals. Even minor errors in the mixing ratio can release volatile organic compounds (VOCs), resulting in a persistent chemical odor that forces homeowners to vacate for days—or even weeks—after installation. The health impact from off-gassing is still being studied, but early exposure has been linked to respiratory and skin irritation.

Risk of Termite Damage

Spray foam covers structural wood components like sills and joists, making it difficult for inspectors to detect termite damage. This hidden risk can escalate quickly, particularly in warm or humid regions prone to termite infestations.

Too Airtight for Comfort or Safety

While airtightness improves thermal performance, excessive sealing without mechanical ventilation creates indoor air quality hazards. Super-tight buildings without ERV/HRV systems can accumulate CO2, humidity, and other pollutants—leading to everything from condensation problems to long-term health risks.

Magra Wool: The Natural Insulation Designed for Real Homes

Crafted from the undercoat of Rajasthan’s Magra sheep, Magra Wool is a pastoral insulation rooted in ancient wisdom and backed by modern performance.

Unlike spray foam, Magra is free from toxins, designed to breathe with your building, and offers natural thermal and acoustic protection—all while supporting India’s pastoral economy.

Key Advantages of Magra Wool Insulation

Breathable and Moisture-Regulating

Magra wool naturally manages humidity. It can absorb up to 33% of its weight in moisture without feeling wet, and then release it as conditions dry. This helps prevent condensation, mold growth, and moisture damage—common issues in sealed environments.

Chemical-Free & VOC-Free

No formaldehyde. No isocyanates. No plastics. Magra insulation is non-toxic, safe to touch, and emits zero VOCs—making it a healthier choice for installers and occupants alike.

Naturally Fire-Resistant

Wool fibers contain high levels of nitrogen and moisture, making Magra naturally flame-resistant without needing chemical additives. It chars instead of igniting, adding a layer of passive fire protection.

Pest-Resistant by Nature

Wool is naturally unappealing to rodents and insects, and Magra undergoes a safe conditioning process to enhance this property—no toxic pest-repellents required.

Thermal Performance Designed by Nature

Magra sheep thrive in the harsh Thar Desert, enduring both searing heat and chilly nights. Their wool offers natural thermal insulation, giving Magra felts an excellent R-value per inch—keeping interiors cooler in summer and warmer in winter.

Acoustic Benefits Built In

With high sound absorption coefficients, Magra Wool also offers superior acoustic performance—ideal for soundproofing interiors in homes, offices, studios, and public buildings.

Easy to Handle and Install

Magra comes in the form of felts, rolls, and batts. No need for hazmat suits or special sprayers. It can be cut and placed using basic tools, reducing labor time and safety risks.

A Material With a Mission: Supporting Rural India

Magra is more than insulation. It’s an ecosystem.

Sourced from Pastoralists: Supporting shepherds from Rajasthan’s drylands.
Processed Locally: Creating employment in rural India.
Sustainably Produced: A circular material using a regenerative fiber.
