VINYL (PVC) MATERIAL CHARACTERISTICS

VS. WOOD

Requires no painting/finishing inside or out--initiallyRequires no painting/finishing inside or out—everMust be painted/stained--initially & repainted
Color sprayed on - will scratch, flake & peel. Color can fade/streak - can require scrubbing and/or painting or touch-upMaintenance-FreePaint can fade, streak, flake, peel - must be repainted periodically
Readily conducts heat and coldHigh resistance to heat loss or gainHigh resistance to heat loss or gain
Supports condensation, frosting in cold weatherResists condensationResists condensation
Waterproof--unaffected by water, except salt waterWaterproof—unaffected by waterWater resistant but vulnerable to water damage
Corrodes in moist, salt-laden air, from pollution and airborne chemicalsResistant to moist, salt-laden air, pollution, airborne chemicalsSwells, rots, deteriorates in moist, salt-laden air, from pollution and airborne chemicals
Impervious to insectsImpervious to insectsResistant to insects, subject to insect damage
Subject to abrasion, corrosion that reduces ease of operation--can cause binding and stickingSmooth surface properties that help prevent moving parts from “sticking”Subject to swelling from moisture, paint build-up that can cause binding and sticking
Structurally rigid and stableStructurally rigid and stable. Many designs with excellent wind load ratingsStructurally rigid and stable. Subject to shrinking, swelling, bowing, warping and cracking
Subject to impact damage, denting & scratchingStrong, durable frames, withstands mechanical stress and strainsSubject to impact damage - denting, splintering
Transmits noiseMulti-chambered design insulates against noiseInsulates against noise
Will not support combustionWill not support combustion. Will burn only while enveloped in flameWill support combustion - burns readily
Material cost fluctuates dramatically - supply is goodMaterial is competitive in cost with other window materials. PVC supply is abundant, price is stablePrices rising dramatically - supply fluctuates
Material is energy intensive to produce, (8-10%), recyclableMaterial is energy efficient to produce, recyclableMaterial is energy intensive to produce - not recyclable
Scrap in production is recyclableLimited scrap in production – recyclableMilling of trees produces tremendous waste. Scrap not readily recyclable. Cutting of trees depletes forests, etc.
Requires finishing which can contribute to “greenhouse” effect, depletes ozoneMaterial requires no finishingRequires finishing and preservative treating which can contribute to “greenhouse” effect, depletes ozone
