Frequently Asked Questions

YetiFoam is a unique and innovative polyurethane foam that expands upon application to create continuous insulation, air barrier, pest barrier, and moisture control. It provides superior thermal resistance, structural support, and eliminates air leaks when applied underfloor.

YetiFoam structure

Unlike traditional insulation such as fiberglass batts or loose-fill, YetiFoam adheres directly to the underside of your floor, creating a seamless barrier that eliminates air leaks. Traditional insulation will sag, leave thermal bridges, and allow airflow into the house. YetiFoam completely seals the underfloor area, eliminates drafts, prevents heat loss, acts as a pest barrier, and ensures seamless installation without the risk of missed areas or poor installation.

At YetiFoam, we utilise a special formulated closed cell spray polyurethane foam (SPF), creating the optimal formulation for your home’s requirements, climate conditions, and performance goals.

Benefits and Performance

Customers commonly report significant energy savings after installing YetiFoam insulation. Exact savings vary depending on your home’s insulation status, climate, and heating/cooling systems. 

Properly installed YetiFoam insulation will last for the lifetime of your home without sagging, compressing, or degrading in thermal effectiveness over time. We confidently offer a lifetime performance guarantee on all installations.

Lifetime Perfomance Guaranteed

Absolutely! Eliminating drafts is one of the primary benefits of YetiFoam. It immediately creates a complete air seal, effectively eliminating cold drafts, which is one of the most noticeable improvements immediately after installation.

YetiFoam creates an effective vapour barrier, significantly reducing the risk of mould, mildew, and rot. It’s particularly beneficial in high-humidity areas where traditional materials fail.

Yes, YetiFoam adds structural support by bonding to your floor joists and subfloor, reducing floor movement, squeaks, and vibrations. Verified data supports significant structural reinforcement.

Lifetime Perfomance Guaranteed

Installation Process

We gather site information remotely to provide pricing, after which our team applies YetiFoam directly beneath your floor. The foam expands, filling cavities and adhering to joists and subfloors, forming seamless insulation. Customers can safely return moments after the installation is complete and properly ventilated.

Installation typically takes around 3 hours for an average-sized house, causing minimal disruption.

No. We use low VOC foam and modern equipment to eliminate off-gassing issues immediately after installation. Our rigorous ventilation procedures ensure no residual odour.

Yes, it’s recommended to vacate your home for a few hours due to power disconnection and equipment noise. Our team will inform you when we’ve completed the job and you can return to your now, extra-comfy home.

Technical Specifications

A standard YetiFoam application of 30mm typically achieves an R2 rating, offering superior thermal performance tailored to your budget and requirements. Unlike traditional insulation, YetiFoam provides a seamless, uninterrupted insulation and air barrier, effectively eliminating air gaps and thermal bridging. These unique properties aren’t fully captured by traditional R-value measurements, which explains why our customers consistently experience outstanding insulation performance.

YetiFoam performs consistently in all climates, offering excellent thermal resistance, moisture control, and air sealing, particularly beneficial in windy or humid environments.

Yes. YetiFoam contains low VOCs, reduced embodied carbon, and significantly lowers long-term environmental impact through enhanced durability and energy efficiency.

All the products we use achieve exceptional fire performance ratings under Australian Standard testing protocols, specifically AS1530. Our insulation materials are classified according to the Building Code of Australia (BCA) requirements and meet the necessary Group Number classifications for underfloor applications. Each installation is performed to ensure compliance with all relevant sections of the National Construction Code.

No. This is a common misconception. YetiFoam will not react or stick to moist timber. It will immediately peel away, making its coverage impossible. This self-regulating property actually helps identify pre-existing moisture issues. If wood is already rotted, spray foam has zero ability to adhere, exposing the damage rather than concealing it. Our thorough inspection process ensures substrate integrity before application.

No. While YetiFoam fully encapsulates surfaces and effectively seals off termites’ access to moisture—causing termite populations to decline—it does not inherently conceal termite infestations. Concerns arise because spray foam insulation covers surfaces that would normally be visually inspected. However, professional pest inspectors can easily remove small sections of insulation for thorough inspection or, as is common practice, note these areas as “not accessible.”

In the USA, several states even include spray foam insulation as a recognised protective barrier against termites, specifically requiring its use in building codes. The rare scenarios of actual concern generally involve unethical practices by homeowners deliberately concealing infestations before selling properties—a situation that could occur with any insulation or building material.

Absolutely not. YetiFoam does not cause mould to grow. Water, air, and humidity cause mould to grow. When a surface is spray foamed with YetiFoam, it becomes completely encapsulated, meaning it is blocked from air and moisture. Mold cannot grow on a surface. 

In extreme cases where mould exists in a subfloor, we can treat it before applying YetiFoam. This ensures that not only can mould not spread, but it is eradicated entirely before insulation is applied. YetiFoam acts as a permanent barrier against the conditions mould needs to thrive, providing long-term protection for your home.

Suitability and Applications

YetiFoam is ideal for homes with suspended timber-framed floors and accessible crawl spaces or basements.

Yes. Older homes often benefit significantly, especially from draft and creak elimination, enhanced comfort, and improved energy efficiency.

Yes, YetiFoam enhances in-floor heating efficiency by directing heat upwards, compatible with specific application protocols for optimal performance.

Cost and Value

Costs vary by home size, access, and preparation requirements. YetiFoam’s superior performance, longevity, and multiple benefits (thermal, air sealing, moisture control, and structural improvement) provide excellent long-term value. Unlike traditional batt insulation, YetiFoam never needs replacing, as batts degrade and lose efficiency over time, making YetiFoam’s long-term cost much better.

Absolutely. YetiFoam provides exceptional long-term value through significant energy savings and elimination of maintenance costs. Beyond energy savings, immediate comfort improvements include warmer floors, eliminated drafts, reduced noise, improved indoor air quality, and increased property value.
