Mesh Netting Insulation Retention for Poultry Barns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation methods for poultry barn attics, such as using cellulosic materials or fiberglass, face issues with low insulative quality, messiness, and reduced coverage due to the need for adhesives like starch and water, which compromise the effectiveness and longevity of the insulation.
Innovation Solution
A method involving non-biodegradable mesh netting attached to the trusses in the attic space to retain blown fiberglass insulation without the need for adhesives, ensuring it stays in place and maintains full insulative coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cellulosic material is sprayed with adhesive to prevent migration, then insulation coverage is maintained, but insulative quality is low and the environment becomes messy
Solution Approach 1:
The patent removes the adhesive component from the insulation system entirely. Instead of spraying cellulosic material with adhesive, the invention uses blown fiberglass insulation that is deposited directly onto the attic floor without any binding agent, eliminating the messiness associated with adhesive application while maintaining coverage through the physical properties of the fiberglass and installation technique
Solution Approach 2:
The patent changes the physical state and application method of the insulation material. By switching from sprayed cellulosic material to blown fiberglass, and from a wet adhesive application to a dry loose-fill installation, the system achieves both complete coverage and cleanliness without requiring adhesive materials
2Reliability
If fiberglass insulation is blown mixed with adhesive and water to prevent migration, then insulation stays in place, but insulative coverage is reduced by at least 30%
Solution Approach 1:
The patent extracts and eliminates the adhesive and water components from the fiberglass insulation system. By using loose-fill blown fiberglass without any liquid additives, the system achieves full insulative coverage without the 30% reduction caused by adhesive mixing, while still preventing migration through proper installation techniques and the physical interlocking of the fiberglass batts
Solution Approach 2:
The patent applies excessive amounts of loose-fill fiberglass insulation to ensure complete coverage and prevent migration. By blowing in more insulation than the minimum required thickness, the system creates a sufficient depth of material that interlocks and stabilizes itself without requiring adhesive, thereby maintaining full insulative coverage
3Ease of manufacture
If cellulosic material is used for insulation, then installation is straightforward, but the material breaks down and compacts over time
Solution Approach 1:
The patent replaces the long-lasting but problematic cellulosic material with fiberglass insulation, which has superior longevity and resistance to breakdown. While fiberglass requires slightly more careful installation, its durability and stability over time far exceed cellulosic materials, making it a better long-term solution despite the marginal increase in installation complexity

AI summary
An apparatus, method and system of insulating a building such as a poultry barn uses netting structurally of the type to hold sod together. The netting is stapled to the bottom of trusses making up the ceiling of a barn and the attic of the barn. Ceiling material is superimposed below the netting to form a ceiling. Loose insulation, typically fiberglass, is blown onto the netting to be held thereby and to form an insulation layer in the attic of the barn.
