About EcoLock Siding
A Comfortable Home Year-Round.
EcoLock delivers outstanding all-weather protection and can reduce your energy costs, thanks to the exceptional R-value of its industry-leading thermal barrier – up to 1½” thick insulation,* the thickest EPS foam available in a one-piece insulated siding system.
Energy Gap Protection.
With innovative features like RigidLock and TrueForm™ combined with a full line of insulated trim and accessories, EcoLock creates a blanket of insulation around your home.
One-Piece Insulated Siding System.
Precision-contoured insulation – up to 1½” thick* – bonds securely to the siding panel, creating an integrated system that delivers remarkable strength and energy efficiency.
Secure Interlocking Panel Design.
EcoLock’s innovative interlocking panel design provides a tight, secure connection between stacked panels. This ensures your siding will be securely locked in, have straight and even course lines, and look great for a lifetime.
Structurally Independent Wall System.
Structural integrity and rigidly interlocking panels mean EcoLock stands tall on its own. The siding that stands on its own will stand up to almost anything.
The Look of Hand-Installed Boards.
Designed and expertly manufactured to capture the look of traditional plank siding. Available in double 6″ clapboard, double 5″ dutch lap and single 7″ profiles.
More Panel. Less Seams.
39% longer than a standard 12′ panel, the 16’8” Extended Length panel design provides fewer installation overlaps for a straighter, cleaner exterior finish.
Crisp, Clean and Subtle.
We drew our inspiration from nature and designed EcoLock with a less-is-more sensibility. The look and feel of EcoLock is an important statement of credibility and taste. Crisp, clean and subtle, the appearance of finely milled wood attracts admiration without seeking attention. The understated look is timeless and genuine.
Traditional vinyl siding is no match for the EcoLock insulated siding system. EcoLock provides exceptional protection against energy loss and the distortion and fading caused by extreme weather. EcoLock’s system bonds an inner core of the thickest, high-density EPS insulation with a durable and beautiful outer layer – creating an integrated system that delivers remarkable strength and performance. The result: your installer can achieve a uniform outer layer with a beautiful finish that holds true.
Quality from a different perspective. EcoLock is designed to look just like single, hand-installed boards. Even from the bottom up.
Intrinsic strength is the hallmark of the MonoWall Integrity feature. Combining secure locking and panel rigidity, EcoLock creates a veritable wall of its own.
