Cork flooring offers natural resilience that reduces fatigue and provides thermal and acoustic insulation. The material’s antimicrobial properties make it ideal for kitchens and bathrooms.
Cork flooring costs moderately more than vinyl but less than premium hardwood while providing unique performance characteristics and sustainability benefits.
Reclaimed Wood Flooring
Reclaimed wood flooring salvages lumber from old buildings, providing character and history while reducing demand for new timber. This option offers unique aesthetics that new wood cannot replicate.
Reclaimed wood often comes from old-growth forests, providing superior grain patterns and density compared to new lumber. The reclamation process also prevents valuable timber from entering landfills.
Prices vary widely depending on species and source, but reclaimed wood often costs less than new premium hardwood while providing superior character and sustainability.
Cellulose Insulation
Cellulose insulation made from recycled paper provides excellent thermal performance and environmentally friendly pest control. This material contains up to 85% recycled content and requires minimal energy to manufacture.
Cellulose insulation offers superior air sealing compared to fiberglass batts, improving energy efficiency. The material’s density also provides better sound dampening than traditional insulation materials.
Cellulose insulation typically costs less than spray foam while providing comparable performance in many applications. The material’s fire-resistant properties also enhance home safety.
Sheep’s Wool Insulation
Sheep’s wool insulation offers natural fire resistance, moisture management, and excellent thermal performance. This renewable material requires minimal processing and provides natural air purification benefits.
Wool insulation naturally regulates humidity, preventing condensation and mold growth. The material’s lanolin content provides natural pest deterrence without chemical treatments.
While sheep’s wool insulation costs more than fiberglass, its superior performance characteristics and natural properties often justify the investment for environmentally conscious builders.
Low-VOC Paints and Finishes
Low-VOC (volatile organic compound) paints and finishes improve indoor air quality while providing excellent performance. These products emit fewer harmful chemicals, creating healthier living environments.
Modern low-VOC paints offer comparable coverage, durability, and color options to traditional paints. Many manufacturers now offer zero-VOC options that eliminate harmful emissions entirely.
Low-VOC paints typically cost slightly more than conventional paints but provide significant health and environmental benefits. The improved indoor air quality can reduce respiratory problems and create more comfortable living spaces.
