Why Does Proper Storage Matter?

ASCEND combines a reinforced exterior surface with an integrated insulated backing. The product is designed to become part of a finished wall—not to serve as a temporary workbench, bridge, platform, or unprotected jobsite surface.

Unsupported cartons may sag or bend. Excessive heat can affect panel shape and surface condition. Construction traffic can crush cartons, while careless removal can damage panel ends, nail hems, locks, factory overlap edges, or finished faces.

How High Can ASCEND Pallets Be Stacked?

The ASCEND Installation Guide states that cladding pallets must not be stacked more than four pallets high. Cladding cartons that are no longer secured as complete pallets must not be stacked more than five cartons high.³

Those are maximum limits—not goals. The storage surface, pallet condition, load stability, forklift access, warehouse configuration, fire-code requirements, and employee-safety rules may justify a lower stack.

Can ASCEND Cartons Be Stored Vertically?

No. The manufacturer specifically states that cartons must not be stored standing up or vertically on end. This applies whether the material is in a warehouse, delivery vehicle, enclosed trailer, garage, or active jobsite.

Vertical storage concentrates the carton’s weight on a relatively small area and can allow long panels to shift, bow, or damage their ends.

How Should ASCEND 7-Inch Plank Be Stored?

ASCEND 7-inch Plank cartons should be stored flat and covered before installation. The supporting surface should be level and should carry the complete carton length rather than leaving sections unsupported.⁴

Do not place the carton over short sawhorses or narrow supports that allow the center or ends to sag. Do not leave part of the carton hanging beyond a truck bed, trailer, rack, pallet, or storage platform.

How Should ASCEND Board & Batten Be Stored?

ASCEND 12-inch Board & Batten cartons should be stored on their wide side and covered before installation. The carton must not be stored standing on its narrow side.⁴

The wide-side orientation distributes the load across a larger surface and helps protect the vertical panel profile from concentrated pressure or movement inside the package.

How Should ASCEND Accessories Be Stored?

ASCEND accessories must be stored flat with their full length supported. They must not be stacked on end. This applies to corner posts, H-trim, J-channel, starter strips, window and door surrounds, and other compatible system accessories.

Long trim components can take a set, twist, bow, or become damaged when only their ends or centers are supported. A distorted accessory can create a visible installation problem even when the surrounding cladding panels remain in good condition.

Should ASCEND Be Stored Indoors?

The manufacturer recommends indoor storage away from direct sources of heat and sunlight whenever possible. Indoor storage protects cartons from weather exposure, airborne debris, construction equipment, uncontrolled heating, and surface contamination.

Indoor storage does not mean placing the material beside a furnace, unit heater, radiator, temporary construction heater, or sun-facing glass wall. The material still must remain away from concentrated heat.

Can ASCEND Be Stored Outdoors?

Outdoor storage requires additional protection. At a distribution location, the manufacturer directs that the protective bonnet or shroud remain on the cartons to help prevent inadvertent surface damage.

At a jobsite, cartons should remain covered while still allowing sufficient air circulation. Do not create a sealed heat trap by wrapping dark plastic tightly over the cartons and leaving them in direct sunlight.

What Is the Maximum Storage Temperature?

ASCEND must not be stored in a location where temperatures may exceed 130°F. The installation guide specifically warns about hot-weather storage on blacktop pavement and beneath dark tarps or plastic that lack proper air circulation.⁵

Ambient air temperature does not need to reach 130°F for the space beneath a dark covering or inside a closed trailer to become dangerously hot. Direct sunlight, dark surfaces, and limited ventilation can create significantly higher material temperatures.

How Should ASCEND Be Transported?

During transportation to the jobsite, cartons must remain flat and supported along their entire length. No part of the carton should overhang the supporting truck bed, trailer, rack, or pallet.⁶

Straps and load restraints must secure the cartons without crushing them. Use broad, controlled restraint rather than placing excessive force across a narrow point.

How Should Cartons Be Opened?

Material can be removed through the carton ends, but the manufacturer recommends cutting the entire length of the carton’s top edge and lifting the material out. This method helps reduce damage to the panel ends.⁷

When opening a carton, do not cut deeply. A knife that penetrates too far can scratch the finished face, cut into the insulated backing, or damage the panel lock or nail hem.

Should Panels Be Pulled from the Carton Ends?

The manufacturer permits material to be pulled from carton ends, but recommends opening the carton along its top edge to reduce the risk of end damage.

Pulling a long panel through a narrow carton opening can catch the factory edge, nail hem, insulated backing, or finished face. The risk increases when the carton has been crushed, exposed to moisture, or improperly stacked.

Can ASCEND Panels Be Dragged?

No. ASCEND material should not be dragged along the ground. Dragging can scratch or damage the panel ends and finished surfaces.

Lift and carry panels with enough support to prevent flexing or contact with abrasive surfaces. Keep the panel face away from concrete, gravel, roofing debris, metal edges, and unfinished scaffolding.

Avoid Bending the Panel Ends

The ASCEND Installation Guide specifically warns installers to avoid bending or damaging panel ends. The ends contain important profile geometry, including factory edges, locking features, nail hems, and insulated backing.

A damaged end may interfere with panel overlap, stack-lock engagement, receiving-channel fit, or finished wall appearance. Do not assume that fastening will straighten a damaged panel permanently.

Keep the Product Clean

ASCEND should be clean when installed on the wall. Dirt, mud, metal shavings, roofing granules, adhesive, sealant, and construction debris can scratch the surface or become trapped behind the panel.

Store panels away from cutting areas and sweeping paths. If a panel becomes dirty, follow the current ASCEND cleaning instructions rather than using an aggressive solvent or abrasive method.

Inspect ASCEND Before Installation

ASCEND’s general instructions require contractors to inspect the product for breakage, foreign objects, surface defects, color consistency, and correctness before installation. Questionable product should not be installed.⁸

What Should Be Done with Questionable Material?

Stop and isolate the material. Record the carton label, product code, color, lot information, delivery date, and visible condition. Photograph the carton and affected panels before cutting, fastening, or altering them.

Contact the distributor or manufacturer for direction. Installing questionable material can destroy evidence, complicate responsibility, and turn a manageable supply issue into an expensive removal problem.

Common ASCEND Storage and Handling Mistakes

What Should Distributors and Contractors Document?

Basic storage and delivery records can help identify when damage occurred and prevent disputes between the manufacturer, distributor, carrier, contractor, and jobsite personnel.

Can Improper Storage Affect Warranty Coverage?

The manufacturer states that it is not responsible for damage caused by improper product storage or handling. That means distortion, scratching, breakage, crushed backing, or other damage caused after manufacture may be treated as a storage, transportation, or workmanship issue rather than a manufacturing defect.

The written ASCEND warranty remains the controlling document for coverage, exclusions, required documentation, claims, and remedies. Contractors should not promise that material damaged on a truck, in a warehouse, or at a jobsite will be covered.

A Clear Contractor Explanation

The Bottom Line

Store ASCEND cartons flat, covered, and fully supported. Do not stack pallets more than four high or individual cartons more than five high. Never stand cartons vertically on end. Store 7-inch Plank flat, place Board & Batten cartons on their wide side, and support accessories along their complete length.

Keep the material away from direct heat, intense sunlight, falling objects, construction activity, and any location that may exceed 130°F. During transportation, support the entire carton and prevent all overhang.

Open cartons carefully, avoid deep knife cuts, do not drag or bend panels, and keep every component clean. Inspect the material before installation and stop when a panel is questionable.

The disciplined standard is simple: protect the material before asking it to protect the house. Damage created in storage or transit does not disappear when the panel is fastened to the wall.
