WALLTITE® Series Closed-Cell Spray Polyurethane Foams Next Generation, Low-GWP ccSPF Insulations
Check this out:
Walltite Spray Foam is a closed-cell, medium-density polyurethane foam (ccSPF) insulation created by the chemical reaction between an isocyanate and a resin. Spray foam is commonly applied in new home construction, renovations, and retrofit projects.
Suitable Climates: Adaptable across climates with application methods suited for cold weather and other conditions; local climate considerations important
Benefits: Reduces energy consumption, provides airtight sealing, supports HVAC efficiency, durable (resists sagging, shrinking, deterioration), adds structural strength, improves indoor air quality, repels water, creates effective vapor barrier preventing condensation and mold, reduces noise transmission, eco-friendly (made from recycled and renewable materials)
Drawbacks: May shrink or crack, deteriorates under direct UV exposure or certain solvents/cleaning agents, susceptible to mold growth with excessive water contact, rodents may burrow into insulation
Application: Used under concrete slabs, ceilings, inside wood or steel framing, foundation walls, attics, basements, and crawlspaces

Check this out:
Icynene Spray Foam is a high-performance polyurethane-based insulation made from 99% water-blown air and recycled materials. It contains no harmful gases, toxic chemicals, or synthetic blowing agents, making it a safe and eco-friendly solution for both new builds and retrofits. Icynene foam expands up to 100 times its original size after application, hardening to seal all gaps.
Suitable Climates: Effective across a wide range of climates
Closed-Cell Icynene: Ideal for extreme temperatures and high humidity; offers high R-value and moisture resistance
Open-Cell Icynene: Suitable for milder climates; breathable and provides sound absorption
Selection depends on building requirements and local climate
Benefits: Non-toxic, creates airtight seal, reduces energy costs, quick curing and re-occupancy time, enhances soundproofing, highly durable, water- and mold-resistant, rodent-resistant
Drawbacks: Higher cost than many other insulations, risk of over-expansion if improperly installed, messy cleanup, requires skilled professional (not DIY-friendly)
Application: Used in walls, roofs, lofts, ceilings, floors, and general residential construction

Sheep's Wool Insulation Guide: Pros, Cons, and FAQs
Quick Tips:
Sheep wool insulation is made from 100% natural, renewable, recyclable, and biodegradable wool sheared from sheep. It undergoes minimal processing before being used as insulation. Its natural properties make it a healthy and sustainable choice for various building applications.
Suitable Climates: Performs well across multiple climate types
Humid/Damp Climates: Breathable and hygroscopic—absorbs up to 30–35% of its weight in moisture without losing insulation performance, helping prevent mold and mildew
Cold Climates: Naturally traps air, retaining heat and keeping interiors warm
Hot/Warm Climates: Regulates temperature by absorbing and releasing moisture, reducing HVAC demand
Note: Proper installation is essential for effectiveness in very damp environments
Benefits: Absorbs excess moisture, mold and mildew resistant, excellent air filtration due to amino acids, maintains R-value (up to 4.3 per inch) for decades, fire resistant and self-extinguishing, rodent and insect resistant (boric acid treated), non-toxic, renewable, low embodied carbon, easy to install, improves soundproofing
Drawbacks: Lower thermal efficiency compared to phenolic and polyurethane foams, requires chemical treatment for pests, more expensive than conventional insulations
Application: Used in roofs, attics, walls, floors, ceilings, insulating pipes, ducting, water tanks, lofts, and as general underlay
