Measuring instructions

Orders are placed in full rolls quantities only.

Calculate underlayment roll quantity needs by estimating your total carpeted area square footage, plus overage. It is recommended to add 10% overage to your estimate. Divide your square footage needs by 135sqft/roll to determine how many rolls you should orders. Always round up to nearest whole number.
Two bedrooms and a hallway renovation, each room is approximately 14'x16' (inclusive of a closeted area), while the hallway is 3.5'x16';

Estimated square footage for the floor area = 504sqft

504sqft x 1.1 for overage = 554.4sqft

554.4sqft / 135sqft/roll = 4.1 rolls

Rounded up for full rolls - this example requires 5 rolls of FiberPad for total project coverage.

Feel the FiberPad Difference

Forgo the foam! When you ditch traditional foam carpet pad, you are choosing to eliminate a major toxic component from your home. Using hemp-based carpet pad, like FiberPad from Hempitecture, you can literally breathe easier knowing that it won't be off-gassing dangerous chemicals, or breaking down into micro-plastics which can ultimately be inhaled or even ingested. You will have cleaner indoor air for you and your family while still having a durable, comfortable carpeted space.


FiberPad, which is made from 80% hemp fiber, derived from industrial hemp plants, is a carpet pad that is both naturally carbon-sequestering, durable, locally produced, and manufactured in a facility run on renewable energy. We truly mean it's clean and green!

The Responsible Carpet Pad Choice

FiberPad is plant based - meaning that it is biodegradable, hypoallergenic, and a non-irritant. There are No VOCs and it is Red List Chemical Free, making it one of the healthiest choices for a carpet pad product. You won't have to worry about toxic off-gassing like from other traditional foam based products.


FiberPad has great thermal and acoustic properties, great dimensional stability and compression resistance. It's also naturally resistant to mold and pests. All of these things are important when creating a comfortable carpeted space. By performance standards, it's the best option available for your home.

A Safe AND Durable Carpet Pad

Traditional carpet padding typically consists of foams and adhesives. One major problem associated with these petrochemical based components is that they are very flammable and create very dangerous fumes in a fire scenario. To combat this - mainstream manufacturers use toxic fire-retardants to offset the risk of smoke inhalation. Unfortunately, there is significant evidence that exposure to these fire retardants through physical touch or the inhalation of dust particles leads to cancer. This is in addition to the risks from unknown quantities/variants of foams and strong adhesives which are made from non-regulated components.

Low Embodied Carbon, Highest Carbon Offset

Moving to a more natural, hemp-based carpet pad product does three main things for you: 1) Gives you peace of mind - you won't be getting sick from breathing in toxic dust particles or the off-gas of chemicals, 2) Further makes your home carbon-sequestering - helping you meet your efficiency or emissions goals by being a carbon storing material, 3) Provides the comfort, warmth, and durability your home deserves in a natural package.
