Siding & Accessories

• Celect Cellular Composite Siding captures the warmth and character of natural wood, combining timeless appeal with excellent performance that withstands even harsh weather conditions.

Backed by a Limited Lifetime Warranty¹ and 25-year color protection, its fade-resistant Kynar Aquatec^® coating ensures long-lasting beauty and eliminates the need for repainting.
• Cedar Renditions is a versatile and modern aluminum accent siding that evokes the beauty of real woodgrain without the maintenance. Cedar Renditions is easy to install, non-flammable, moisture-proof, non-combustible and virtually maintenance-free.
