Support Us

HempLime products are a superfood for the building industry. Products made from Hemp and Lime offer healthier alternatives in the categories of insulation, wall systems, textiles, and more in large part because they do not contain harmful petrochemicals. They absorb carbon dioxide from the atmosphere, hemp plants sequester carbon while regenerating depleted soils, and HempLime products are naturally fire-resistant. Hemp and lime products can be fully recycled and reused to support a zero-waste economy.

Additionally, the burgeoning hemp industry in the US supports regenerative economies and is tackling issues of social justice through agriculture and workforce development.

About Our Collections

The goal of our collections is to help promote transparency in the material ingredients of building products by fostering knowledge and awareness of products and materials for which life-cycle information is available, and that have environmentally, economically, and socially preferable life-cycle impacts.

Keep an eye out for the following symbols:
A Healthier Affordable Building Product

Products with the designation of "Healthier & Affordable" were specified and installed in at least one of our Case Studies of healthier affordable housing.

Available at the Donghia healthier Materials Library

The Donghia healthier Materials Library library is open to Parsons student and faculty. Learn more about access and opening hours here.

Ingredient Disclosures

There are several ways of evaluating a material’s health that we include with product information. Disclosures are reports by manufacturers about product ingredients, impacts, or other attributes.

Key Disclosures include:
Health Product Declaration (HPD)

A voluntary technical specification for reporting information on product contents and associated health information, intended to be the health-analogue to Environmental Product Declarations (EPDs).

Declare Label

Declare is a transparency platform and product database that answers three questions: 
  1. Where does a product come from?
  2. What is it made of?
  3. Where does it go at the end of its life?

Environmental Product Declaration (EPD)

A standardized format for communicating the environmental effects associated with a product’s raw materials extraction, energy use, chemical makeup, waste generation, and emissions to air, soil, and water.

Safety Data Sheet (SDS)

A reporting format that provides basic information about a material’s chemical ingredients, the potential safety hazards to installers, and recommended practices for installation.

Hemp Oil

Hemp oil is a healthier finish and works particularly well on wood. The Real Milk Paint’s Hemp Oil is free of additives, preservatives, solvents, and VOCs. It is thinner than tung oil, making it easier to apply without the addition of a solvent. However, hemp oil is less durable and waterproof than tung oil. Hemp oil is food safe and works especially well on lightly used items.

Hempcrete Block

IsoHemp’s hempcrete blocks are a non-load-bearing masonry product. These natural, healthy blocks are designed to be used for insulating envelopes, partition walls, and counter-partitions. Made only from hemp and lime, hempcrete’s ability to diffuse accumulated heat makes it a fantastic thermal regulator. This product also regulates humidity due to its permeability and is naturally very fire-resistant, making toxic flame retardants obsolete. Not only are IsoHemp hempcrete blocks good for human health, they also have a positive environmental impact. Their manufacture requires very little energy, and they act as a carbon sink, actively absorbing CO2 from the air.

Hempwool

Hempwool insulation has a low carbon footprint, shows excellent insulation values, is hypoallergenic and due to its ingredients allows for a non-hazardous installation.According to Hempitecture, the mix of 92% hemp fiber and 8% polyester are heated in order to bond and increase the strength. Polyester is petrochemically based and will not biodegrade. Alternatives are other man-made substances, currently. We appreciate this North American made product and look forward to a healthier option as it evolves.

HES-hemp hurd

Hemp hurds are the tough woody interior of the hemp plant. It is won by decorticating - separating - the inner hurd material from the softer, fibrous exterior of the stalk.

The component silica (sand) in the plant prevents from burning or rotting and with the immense strength of the hurd it makes Hemp Hurd an versatile building material - it is used in, e.g., insulation and wall systems.

HES Hemp Hurd is mainly from Europe with the US distribution currently on the west coast.

Ecologic Trademark LimeWash Platinum

Ecologic™ LimeWash Platinum is a mineral coating which bonds as crystals form in the pores of the substrate. It is breathable and due to substrate and mineral joined together, water or salts cannot cause the surface to bubble or flake.

Limeworks are serious experts through their profound experience in masonry, historic restoration and working with Lime - Naturally Hydrated Lime (NHL).Due to substantially less energy usage during production with NHL, the release of CO2 into the atmosphere is reduced considerably. Furthermore, Natural Hydraulic Lime (NHL) reabsorbs most of the CO2 during the curing process, while cement reabsorbs none.

ADDED BENEFITS OF USING HEMPLIME PRODUCTS:

Interior Health: HempLime products are naturally pest, mold, and fire-resistant.

Interior Quality: HempLime products have excellent acoustic properties, and naturally regulate humidity and heat.

Energy Efficiency: The insulative properties of HempLime make it an energy-efficient building material and requires very little energy to produce. The amount of CO2 sequestered during hemp's growth exceeds the amount emitted during production. Similarly, the CO2 emitted while processing limestone to make lime is re-absorbed as lime cures.

Zero Waste: Hemp and Lime are naturally biodegradable and 100% recyclable and reusable.

Spec Guidance

Clean Hemp Hurd. Keeping hemp hurd free of dirt and fibers is paramount to having a good end result.

Hemp/Lime Binder. Use a lime binder that is specifically designed for hemp/lime building.

Aggregate in the mix. The type and coarseness of aggregate impacts the function of the Lime products; seek guidance on the right composition for your project.

Hempcrete without cement. HempLime mix should be free from any cement additives. An ingredient disclosure will help you rest assured.

As this industry grows, we will be able to find local suppliers for Hemp and Lime products. This will contribute to lowering the carbon footprint.
