WHAT IS Gypsum Underlayment?

​

Gypsum Underlayment is a mixture of gypsum plaster, Portland cement and sand. It is commonly used for wood-frame and concrete construction structures as a floor underlayment meaning that it’s the layer that sits between wood subfloor and the floor covering of a building.

WHAT ARE THE BENEFITS OF USING Gypsum Underlayment?

​

Gypsum Underlayment has many benefits as a floor underlayment.

 

• Fire resistance - Gypsum Underlayment is fire retardant! This is because it has crystallized water, so when it’s exposed to extremely high temperatures it evaporates; cooling and slowing down heat transmission.

​

•  Durability - Gypsum Underlayment is very similar to concrete and is very resistant to cracks. It is a great and reliable alternative to concrete.

​

• Reduces sound - Gypsum Underlayment is a great floor underlayment for houses and apartment buildings where you don’t want sound to travel.

​

• Easy to install - Gypsum Underlayment is much more lightweight than concrete, making it easier to pour and cure
