Ecovative is investigating the structural properties of its organic composites, as well as methods for producing hybrid composites with internal structural members. The use of an internal structural member within a Greensulate composite, such as fast-growing bamboo, could allow Ecovative to engineer a structural composite with compressive strength 75 times higher that of polystyrene. Experiments and research are currently pursuing optimal growth methods for the embedded composites.

Ecovative’s engineers are developing and testing Greensulate to meet compliance with the American Society for Testing and Materials (ASTM) Standards. These standards include structural testing, which determines the tensile and compressive strength of the organic composite, and water sorption and permeability.

While Ecovative's development team is committed to the production of environmentally friendly products, they are also unwilling to compromise the quality of the work they produce to that end. Ecovative uses state-of-the-art R-value testing equipment to ensure that Greensulate's resistance to heat transfer is comparable to the competition. Testing performed on Greensulate™ by Ecovative engineers using a HotDisk have shown that Greensulate™ has a highly competitive R-Value of 3 per inch. The goal of our ongoing research and development is to improve on that standard. 

While Greensulate's insulating properties make it an ideal way to keep your home warm, Greensulate can also help keep it safe. Combustibility testing has demonstrated that Greensulate can function as a firewall, as well as an insulator. In comparison with its polystyrene counterparts, Greensulate exhibited ideal firewall characteristics, maintaining structural integrity and removing ambient heat energy from its surroundings. Initial testing for ASTM compliance is being conducted at WPI.
