In straw-bale construction, straw bales, often made of wheat, rice, rye, and oat straw, are used as structural support, building insulation, or both. Natural building or “brown” construction projects frequently use this construction technique.
According to research, straw-bale construction is a sustainable building technique in terms of both the materials used and the energy required for heating and cooling. The regenerative nature of straw, cost, ease of availability, inherently fire-retardant properties, and high insulating value are benefits of straw-bale construction over traditional building methods.
A disadvantage of straw is that it takes up a lot of space and is susceptible to decay. It is also difficult to get insurance coverage. Seven out of eight places with moisture concentrations of less than 20% were found in research employing moisture probes inserted into the straw wall. This degree of moisture prevents the degradation of the straw.
However, much like with the construction of any sort of building, proper straw-bale wall construction is crucial to maintaining low moisture levels. With a moisture barrier or capillary break between the bales and their supporting platform, straw bale buildings are normally constructed by stacking rows of bales on a raised footing or foundation.
Straw bales can be divided into two categories: those with two strings and those with three. In all three dimensions, the three string bale is larger. Bale walls can be fastened together using bamboo or wood pins, surface wire meshes, or other fasteners before being stuccoed or plastered with a lime-based product or an earth/clay render.
As was the case with the original structure, the bales might really act as the building’s structural support. The plastered bale assembly can be made to handle wind and seismic loads in both lateral and shear directions.
The Global Straw bale construction market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
It is with great pleasure that Greenfield Technologies Corp. announces thelaunch of NForce Construction Bales, a new premium Straw bale construction made from structural bast fiber produced by a HempTrain Advanced Processing Plant.
The HempTrain Advanced Processing Plant is the only hemp processing technology in existence that separates the bast fiber from hurd without damaging the fiber strings, preserving the fiber’s length and structural integrity while maintaining high tensile strength.
The addition of premium construction-grade bales to the product line, which already includes the hugely popular NForce-Fiber and NForce-Pro—the only ASTM/CSA compliant high-performance hemp fiber in the world for concrete construction—further broadens CGT’s NForce brand of engineered fiber products. Any turn-key HempTrain operation can produce Construction Bale product lines with the addition of an inexpensive CGTBaler.
