Thermal and Economic Performance of Recycled Asphalt Roof Insulation in Brazil

A civil construction project measured the thermal insulation of an inn's roof in São Joaquim, SC, one of Brazil's coldest regions. The results show a recycled asphalt blanket reduces roof heat loss between 68 and 72% and has a material cost two to five times smaller than other studied insulators. The dataset, from an open-access paper by Mágilla Feitosa Medeiros, indicates the economic viability and environmental benefits of this recycled material.

Use Cases

• Compare thermal performance of recycled asphalt against conventional insulators based on the reported 68-72% heat loss reduction.
• Assess economic viability of construction materials based on the described two to five times lower material cost.
• Model building energy efficiency in cold climates based on the insulation measurements from a specific Brazilian region.
• Evaluate environmental impact of construction waste reuse based on the description of the material being more environmentally friendly.

Strengths

• Provides specific performance metrics, including a 68-72% reduction in roof heat loss.
• Includes direct economic comparison, stating material cost is two to five times smaller than alternatives.
• Focuses on a real-world application in a defined geographic location (São Joaquim, SC, Brazil).

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Data may reflect geographic bias inherent to a single case study location.
