What Is MonZon Protect It?

Definition: MonZon Protect It is a proprietary modular temporary enclosure system manufactured by MonZon — a Swedish scaffolding company with three generations of industry experience — that creates a fully enclosed, weatherproof workspace over construction, shipbuilding, renovation, or industrial maintenance projects by erecting a self-supporting aluminum structural framework clad in roof and wall panels to seal the work area from the elements. Unlike tarp-and-frame weather protection, which covers a work area from above but leaves the sides open to wind, temperature, and precipitation, Protect It is designed to enclose the full project envelope — creating an interior environment in which workers, materials, and equipment are shielded from weather on all sides, and in which temperature can be maintained with temporary heating systems to allow work to continue through winter and in climates where outdoor conditions would otherwise halt production entirely.

The Protect It system is built from lightweight, recyclable aluminum structural components that assemble into a rigid frame capable of spanning large, complex project footprints. The system accommodates asymmetrical and symmetrical layouts and multiple roof configurations — double-pitched (gable), mono-pitched (shed), and mansard profiles — giving engineers the flexibility to match the enclosure geometry to the specific project site, the shape of the structure being worked on, and the access and crane clearance requirements the program demands. A motorized retractable roof feature allows sections of the enclosure to open on demand — enabling crane lifts, material deliveries, and launch operations to be conducted through the roof opening without dismantling the enclosure — and then to close again to restore full weather protection once the operation is complete. MonZon Protect It is distributed in the United States exclusively through APi National Scaffold, which designs, installs, and manages Protect It enclosures for the North American market.

For project owners and program managers evaluating MonZon Protect It, the core value proposition is schedule and productivity protection: the system allows work to continue at full production rates through weather events that would otherwise shut a project down, while providing the temperature-controlled environment that material and coating systems, precision fabrication, and worker safety in extreme cold all require. On programs with aggressive timelines and high per-day cost-of-delay, the cost of the Protect It enclosure is evaluated against the cost of weather-related downtime that the enclosure eliminates, frequently making a compelling economic case for projects in regions with significant winter seasons or year-round precipitation exposure.

MonZon Protect It System Components

The Protect It system assembles from a set of engineered aluminum components that combine to create the structural frame, roof, and wall cladding of the temporary enclosure.

Structure

Aluminum Structural Framework

The load-bearing frame of the Protect It enclosure is built from engineered aluminum structural members — columns, rafters, and purlins — that assemble without welding using bolted or pinned connections into a self-supporting rigid structure capable of spanning large project footprints. The aluminum construction keeps component weight low enough for field assembly without heavy lifting equipment while delivering the structural capacity required for snow, wind, and live loads in accordance with the project's local building code requirements.

Roof

Multi-Configuration Roof System

Protect It's roof structure accommodates double-pitched (gable), mono-pitched (shed), and mansard roof profiles in both symmetrical and asymmetrical configurations — allowing the enclosure geometry to be engineered to the specific project site, the shape and height of the structure being enclosed, and the drainage, clearance, and access requirements of the program. The roof panels are typically aluminum sandwich panel or cladding designed to shed precipitation, withstand wind loading, and provide the structural diaphragm stiffness the enclosure frame requires.

Roof Feature

Motorized Retractable Roof

A motorized retractable roof section allows designated panels to open on demand — enabling crane lifts, material deliveries by overhead equipment, and ship launch or drydock operations to be conducted through the roof opening without requiring enclosure dismantlement. Once the overhead operation is complete, the retractable section closes to restore full weather protection. This feature is particularly critical on shipbuilding programs where a fixed enclosure roof would prevent the overhead crane access that ship construction requires at multiple stages throughout the build sequence.

Cladding

Wall and End Panel Cladding

The enclosure's side walls and end gables are clad in panels that close the structure from wind, precipitation, and temperature — completing the sealed interior environment that distinguishes Protect It from open-sided weather canopies. Wall panels typically incorporate door and personnel access openings, large equipment access doors for forklifts and material handling, and windows or translucent panels to provide natural daylighting to the enclosed workspace without compromising the enclosure's weather seal.

Foundation

Base and Foundation Interface

The Protect It frame transfers its structural loads to the ground or working surface through a base connection system engineered to the specific site conditions — concrete slabs, soil anchors, or the deck of a drydock or marine facility. The foundation design is project-specific and is engineered as part of the full Protect It installation design package, accounting for the lateral wind loads and vertical gravity loads the enclosure frame generates under the design weather conditions for the project location.

Heating

Temporary Heating System Compatibility

The sealed interior environment that Protect It creates is compatible with temporary heating systems — direct-fired or indirect-fired heaters, radiant systems, or forced-air units — that maintain interior temperatures above the minimum thresholds required for worker safety, concrete curing, coating application, and precision fabrication work in cold weather. The enclosure's weather seal significantly reduces the heating load relative to open-air winter construction by eliminating the wind and precipitation exposure that drive heat loss on unprotected job sites.

Where MonZon Protect It Is Used

Protect It is deployed on large-scale programs where the cost of weather-related downtime justifies investment in a full temporary enclosure and where the work scope or timeline cannot accommodate seasonal weather delays.

Shipbuilding and vessel construction — enclosing drydocks and shipyard building halls to allow year-round ship construction and outfitting unaffected by maritime weather conditions, as demonstrated at Fraser Shipyards on Lake Superior

Ship repair and drydock maintenance — creating a weatherproof environment for hull blasting, coating, and structural repair work on vessels in drydock where coating application windows and surface preparation standards require controlled conditions

Bridge rehabilitation and restoration — enclosing bridge structures to allow year-round lead paint abatement, structural repair, and recoating on bridge programs where weather downtime extends already-long project timelines and traffic management costs

Large structure coating and abatement — enclosing industrial vessels, tanks, structural steel, and large equipment for surface preparation and coating work where temperature, humidity, and dew point control are required to meet coating specification limits

Building construction in severe climates — enclosing building construction programs in regions with significant winter seasons to allow year-round concrete work, structural steel erection, and envelope construction without cold-weather protection and reheating costs on open sites

Historic building and facade restoration — enclosing historic facades and structures for masonry cleaning, repointing, stone repair, and coating work where precipitation exposure would interrupt the restoration process and contaminate sensitive materials

Industrial equipment overhaul and turnaround — enclosing large industrial equipment, compressors, turbines, and process vessels during planned maintenance turnarounds where weather exposure would affect work quality, safety, and schedule

Special events and temporary structures — providing temporary covered venues for large outdoor events where weather risk would affect attendance, production, or safety and where a permanent building is not available or warranted

MonZon Protect It Planning and Procurement

MonZon Protect It enclosures are engineering-intensive temporary structures that require early program integration to deliver their full schedule and cost protection value. The structural design of a Protect It enclosure — span, roof configuration, foundation system, retractable roof location, wall panel layout, and access door placement — must be developed with knowledge of the project's work scope, crane and material handling requirements, site geometry, foundation conditions, and the design wind and snow loads applicable to the project location. Engaging an experienced Protect It contractor early in the program design phase allows the enclosure to be co-engineered with the project's scaffold, crane, and material handling plans rather than adapted to them after the fact — producing a more efficient enclosure design and avoiding field changes that delay mobilization. The motorized retractable roof is the most operationally significant feature for shipbuilding and heavy industrial programs where crane access through the enclosure roof is required at defined points in the work sequence; sequencing the retractable roof position with the program's crane lift plan requires coordination between the enclosure contractor and the construction manager before the enclosure is designed and built. Lead time for Protect It enclosure design, fabrication or inventory sourcing, and installation is substantial for large programs; project managers should initiate enclosure planning well in advance of the construction mobilization date rather than treating the enclosure as a procurement item that can be resolved in parallel with construction startup. OSHA 29 CFR 1926 Subpart E governs personal protective equipment in construction including requirements for protecting workers from adverse weather; a properly designed and installed Protect It enclosure addresses weather exposure at the program level, but individual worker PPE requirements for work within the enclosure must be evaluated against the specific tasks and hazards present regardless of the enclosure's weather protection. The enclosure's fall protection requirements at interior elevated work levels are governed by 29 CFR 1926 Subpart M; the Protect It enclosure structure itself does not constitute a fall protection system for workers inside it.

Engage a Protect It contractor during program design — enclosure geometry, roof configuration, and retractable roof placement should be co-engineered with the project's crane plan, scaffold design, and material handling layout before construction mobilization
Define the retractable roof requirements early — identify the crane lift points and overhead access operations the program will require through the roof, and incorporate those into the enclosure design rather than modifying a fixed roof after the fact
Confirm the structural engineering basis — the Protect It enclosure is a temporary structure subject to wind and snow loading; confirm that the enclosure design is stamped by a licensed professional engineer for the design loads applicable to the project location
Verify foundation conditions and design — the enclosure frame transfers significant lateral and vertical loads to the ground or deck surface; confirm that the foundation design accounts for actual site conditions including soil bearing capacity, slab capacity, or marine deck loading
Plan the heating system in parallel with the enclosure — if the enclosed workspace must be maintained above a minimum temperature for work, coating application, or concrete curing, size and specify the temporary heating system before the enclosure is installed rather than adding it as an afterthought
Coordinate enclosure access with the project's traffic plan — large equipment doors, personnel access points, and emergency egress from the enclosure must be positioned and sized to accommodate the project's material handling, equipment movement, and life-safety egress requirements
Address fall protection inside the enclosure separately — Protect It encloses the project from weather but does not address fall hazards at elevated work levels inside; confirm that scaffold, guardrail, and personal fall arrest systems inside the enclosure comply with 29 CFR 1926 Subpart M
Verify the contractor's Protect It experience and APi National Scaffold relationship — confirm that the enclosure contractor has direct experience designing and installing Protect It systems and access to the system's components through the authorized U.S. distribution network

Frequently Asked Questions

MonZon Protect It is a modular aluminum temporary enclosure system engineered to create a fully enclosed, weatherproof workspace over large construction, shipbuilding, and industrial maintenance projects. Where conventional weather protection — tarps, scaffold-supported shrink wrap, or open-sided canopies — covers a project from above while leaving the sides exposed to wind, driven rain, and temperature, Protect It encloses the full project envelope on all sides, creating an interior environment that is genuinely sealed from the elements and that can be heated to maintain workable interior temperatures through winter and in climates with sustained extreme cold. The system is built from recyclable aluminum components engineered into a self-supporting structural frame — not a scaffold frame with sheeting attached — allowing it to span large and complex project footprints without the intermediate column grid that a scaffold-based enclosure would require. The motorized retractable roof section is the system's most operationally distinctive feature: it allows designated roof panels to open on demand for crane lifts, material deliveries, and marine operations, then close again to restore full weather protection, making Protect It viable on shipbuilding programs and other heavy industrial projects where overhead crane access through the enclosure roof is required repeatedly throughout the work sequence. MonZon is a Swedish company with three generations of experience in the scaffolding and weather protection industry, and Protect It is their flagship large-scale enclosure product. In the United States, Protect It is distributed and installed exclusively through APi National Scaffold, which manages the system's design, engineering, and installation for the North American market.

Protect It supports three primary roof configurations: double-pitched (gable), mono-pitched (shed), and mansard profiles, each available in both symmetrical and asymmetrical layouts. The double-pitched gable roof is the most common configuration for wide-span enclosures where the structure being enclosed is centered in the span and precipitation drainage to both sides of the enclosure is preferred — it produces the greatest clear interior height at the ridge and the most efficient structural behavior for symmetric loading. The mono-pitched shed roof directs drainage to one side and is used where the project geometry, adjacent structure, or site drainage constraints make one-directional roof drainage preferable, or where the enclosure must be built asymmetrically relative to the structure it covers. The mansard profile uses a steeper lower slope and a shallower upper slope, which provides more usable interior height near the enclosure walls than a standard gable roof of the same overall height and is used on projects where interior clearance at the perimeter of the enclosed area is critical. Asymmetrical configurations allow the roof ridge to be offset from the center of the enclosure plan, enabling the enclosure to accommodate structures or work areas that are not centered within the span, or to match specific crane clearance or retractable roof positioning requirements. The roof configuration selection is part of the enclosure's engineering design process, driven by the specific project geometry, crane and access requirements, site constraints, and structural efficiency considerations rather than by a standard default configuration.

The motorized retractable roof is a section of the Protect It enclosure's roof panels that is mounted on a motorized track system allowing it to slide or retract to open a defined area of the enclosure roof on demand. When the retractable section is closed, it is part of the continuous weatherproof roof surface, indistinguishable in function from the fixed roof panels surrounding it. When opened, it creates an overhead aperture through which a crane hook, rigging, and loads can pass from above the enclosure into the enclosed workspace below without requiring any dismantling of the enclosure structure or sheeting. For shipbuilding programs, the retractable roof is operationally essential: ship construction involves repeated crane lifts of large hull sections, machinery, and outfitting components throughout the build sequence, and a fixed enclosure roof without a retractable section would block every crane lift — making the enclosure incompatible with the construction process. At Fraser Shipyards, where APi National Scaffold installed Protect It for a 150-passenger ferry construction project on Lake Superior, the retractable roof allowed the shipbuilding process to proceed under full weather protection while retaining the overhead crane access the build required at each stage of construction. The motorized actuation allows the roof section to be opened and closed quickly — typically operated from a control station at ground level — minimizing the time the enclosure interior is exposed to the elements during crane operations.

A Protect It enclosure is a temporary structure subject to the same categories of structural loads that govern any exterior structure, and its design must account for these loads to ensure the enclosure performs safely through the weather conditions it is intended to withstand. Dead load covers the weight of the aluminum structural frame and cladding panels themselves. Live load includes the weight of personnel, equipment, and materials that may be supported on the enclosure structure — for example, heating units or lighting attached to the frame. Snow load is defined by the project location's ground snow load from ASCE 7 or the applicable local building code, converted to a roof snow load based on the roof geometry, exposure, and thermal conditions of the enclosure. Wind load is the dominant lateral load on large enclosures and is determined by the design wind speed at the project location, the enclosure's exposure category, the roof shape and cladding pressure coefficients, and the enclosure's overall geometry — large flat-sided enclosures can be subject to substantial wind loads that drive both the frame design and the foundation anchorage requirements. Seismic load applies in seismically active regions and must be addressed in the enclosure design for projects in ASCE 7 Seismic Design Categories C through F. Foundation loads transfer the combined effects of all applied loads to the ground, deck, or structural slab supporting the enclosure — and the foundation design must be compatible with the actual bearing capacity or structural capacity of the support surface. The enclosure design should be prepared or reviewed by a licensed professional engineer registered in the state where the project is located and should be stamped for the specific design loads applicable to the project location and duration.

Yes — while Protect It's most prominent documented North American application is shipbuilding at Fraser Shipyards, the system is engineered for any large-scale program where full-enclosure weather protection creates significant value relative to its cost. The economic case for Protect It is strongest on programs where some combination of the following conditions applies: the project has an aggressive schedule where weather downtime directly threatens deadline compliance; the work scope requires controlled temperature, humidity, or surface conditions that outdoor weather cannot reliably provide (coating application, concrete curing, precision fabrication); the project is in a region with a significant winter season where outdoor construction would otherwise be seasonally interrupted; the cost of weather-related downtime per day is high relative to the enclosure cost amortized over the project duration; or the structure being worked on is too large or too valuable to be protected by conventional tarp and scaffold enclosures. Bridge rehabilitation, large structure coating and abatement, industrial equipment overhaul, historic building restoration, and large commercial construction programs in northern climates are all viable Protect It applications that share the same fundamental value logic as shipbuilding — they involve large, complex work scopes where weather protection at the project envelope level provides more productivity protection than any other single mitigation. Projects that are small in footprint, short in duration, or in climates where weather downtime risk is modest are generally better served by conventional scaffold-supported enclosures rather than an engineered aluminum temporary building system.
