Patented in 1860, linoleum was the most popular kitchen flooring and countertop material in the 1930s and 1940s. By the 1960s, linoleum began to lose its popularity to vinyl. Today, it’s making a strong comeback, partially due to its sustainability.

Linoleum is made from linseed oil (from flax seed), ground cork or wood flour, and plant resins — all renewable resources. This mixture is pressed onto a backing, usually jute or polyglass [fiberglass and polyester fibers].
Linoleum is regaining its popularity because of its many favorable qualities including being sustainable. It's made from natural, renewable resources and it's biodegradable. Manufacturing generate little waste, recycling most of it back into the product.
This is a durable, resilient product, stable at varying temperatures and humidities. Linoleum sheet has a static load resistance of 150 psi. Linoleum tile has a load resistance of 700 psi. It resists indentations, cracks and water. It is resistant to burning. It is innately anti-bacterial, naturally killing bacteria and molds. It is cost-effective with a life span of at least 40 years. No offgassing formaldehyde, although linoleum can sometimes have a strong natural odor when first installed. This odor can be bothersome to the more sensitive person. Sealing it reduces any odors.
Linoleum is available in a variety of colors, both solid and marbleized patterns. These colors extend through the entire thickness of the material, which decreases the amount of visible wear, increasing the life of the material. Although water resistant, proper moisture protection from the subfloor during and after installation is recommended. A low maintenance cost and effort generally only involves a dry maintenance system and periodic buffing.
Installation: Linoleum is often glued directly to the subfloor. Sealants are recommended to add protection against moisture and scuffing. We prefer water-based adhesives and sealants. Although water resistant, proper moisture protection from the sub-floor during and after installation is recommended. We also recommend installation by qualified professionals specifically familiar with installing linoleum and sealing it. Special installation requirements are necessary in some situations.
