50 Eco-Friendly Products Selected by Green Builder's Editors

 

Owens_Corning_EcoTouch_web

This two-part, latex-based foam seals cracks and penetrations through a building envelope, and from floor to floor. Approved for use as a fireblock, and around plumbing penetrations and electrical wireways, it’s the only self-forming gasket system offering energy code compliance. By keeping airborne moisture from entering wall cavities, EnergyComplete also reduces the chance of mold growth, and creates a first line of defense against insects and other pests. This sealant is non-allergenic, and safe to use without a chemical mask or ventilation suit.

RhinoLinings_1_web

This open-cell, semi-rigid, polyurethane foam does away with ozone-depleting propellants by being completely water blown. With a density of 0.5 per cubic foot and a minimum of 3 percent bio-based material, this product expands 100:1 when sprayed, filling voids and crevices and reducing infiltration—and consequently, energy demand. With an R-value of 3.8 per inch—R-20 at 5.5”—Bio-Based 501W contributes to a tight building envelope, while reducing the risk of moisture accumulation and sound transfer.

CertainTeed_MemBrain_web

Designed for application over unfaced fiberglass insulation, MemBrain looks like polyethylene, but is actually a polyamide-based material. What makes this product unique is its ability to adapt its permeability to varying climatic conditions. In winter or low humidity, MemBrain resists water vapor, behaving like a traditional vapor retarder. As the relative humidity increases, so does MemBrain’s permeability, allowing water vapor to escape the wall cavity and helping buildings dry out.

Icynene_ProSealEco_web

This closed-cell, medium-density spray foam insulation maintains its installed R-value throughout its service life, unlike air-permeable insulation types, which lose their field thermal performance because of sagging, shrinking and ongoing convective current loops within the insulation. This product is also 100 percent water-blown, eliminating ozone-depleting blowing agents. With an R-Value of 4.9 per inch and superior adhesion performance, ProSeal Eco is suitable for projects in any climate zone across North America.

DuPont_web

This housewrap offers builders the optimal balance of air, water and thermal protection, all in one roll. ThermaWrap R5.0 provides continuous exterior insulation, while reducing thermal bridging through exterior walls. It also lowers energy costs by reducing air leakage, keeping cavity insulation dry and performing at its installed R-value. At the same time, breathability helps prevent mold and water damage, and improves air quality. Made in the U.S. with 20 percent pre-consumer, recycled polyolefin, ThermaWrap R5.0 contains no added fire-retardant chemicals.

Ecovative_PastedGraphic-2_web

Building on its initial innovation—a packaging material made from agricultural waste and mushroom mycelium—Ecovative is in the process of creating a line of completely renewable, petroleum-free insulation products. As featured in the company’s demonstration project, the Mushroom Tiny House, live Mushroom Insulation is grown in-place under controlled conditions. The insulation solidifies, sets, and dries out over the course of about a month, resulting in an airtight, highly insulated structural wall assembly. Ecovative is also developing SIPs, acoustic panels and rigid board insulation.
