Modern Shed Vs Competitors

Modern Shed vs Competitors

How a Modern Shed is built, compared with a typical prefab shed

Every line meets or exceeds the International Building Code (IBC), which is what makes permitting faster and simpler where a permit is required.

Component	Modern Shed	Typical prefab shed	Why it matters
Hand built by craftsmen	Yes	Not likely	Attention to detail through pride of craftsmanship makes each Modern Shed specifically for its customer.
Floor system and panels
4×10 pressure-treated perimeter beam	Yes	No	A strong, durable foundation element that allows ground, slab or near-ground contact.
2×6 to 2×10 floor joists	Yes	No	Joist depth is chosen for the span, which allows higher insulation values and meets permitting requirements.
Pre-insulated floor (R21)	Yes	No	R21 insulation is installed at the factory, which reduces labor cost on site and makes for a warmer floor.
Underside sheathed with pressure-treated plywood	Yes	No	Allows ground or slab contact closer than 18″ from grade and reduces the chance of pest intrusion.
¾″ ACX sanded plywood sub-floor	Yes	No	Sanded plywood is flooring-ready: smooth enough to lay tile, vinyl, wood or carpet directly. Other sub-floor materials are not.
Screwed, glued and nailed	Yes	No	Multiple attachment methods greatly reduce the chance of squeaks over time.
Ledger board and nested panels	Yes	No	Panels are easy to carry, arrive already manufactured, need no saws or sawdust on site, and are stronger and more stable.
16″ on-center floor joists and panels	Yes	No	Reduces panel weight for easier carrying, exceeds building code, and increases floor strength for heavy objects.
Wall panels
2×4 and 2×6 framing options	Yes	No	Standard 2×4 walls with R13 insulation are code-compliant in many places; optional 2×6 walls with R21 insulation meet code where more is required.
ZIP System® sheathing	Yes	No	Structural sheathing with an integrated water-resistive barrier, so the wall is weather-protected without a separate house wrap.
16″ on-center studs, double studs at every panel connection	Yes	No	Exceeds typical code requirements, for easier permitting and a stronger structure.
All studs pre-drilled at outlet height	Yes	No	Makes electrical wiring easier for your electrician, reducing their time and cost.
Pressure-treated bottom plate for slab installs	Yes	No	Code-compliant from the factory for units placed on a slab without a floor system.
Field-applied secondary top plate	Yes	No	Added strength across the panel system guards against bowing or bending of the wall.
Top cap with integrated transom glass units	Yes	No	Maximum natural light without going to oversized windows.
Full-length structural glulam beam	Yes	No	Allows a smaller profile with no header above the transom glass, and adds considerable strength to the roof in earthquake, high wind or a fallen tree.
Siding
James Hardie lap siding	Yes	Yes	A mainstream residential siding. Modern Shed specifies the smooth texture with a larger reveal and Tamlyn metal trim corners for a modern aesthetic.
Open-joint rain-screen siding (Modern Shed exclusive)	Yes	No	A true rain screen keeps moisture out while letting the building breathe; three layers of protection keep the structure as energy-efficient as possible.
Cedar, metal, Azek and other James Hardie siding options	Yes	Varies	Lets you customize the exterior to match your home and make the space your own.
Doors and windows
Ply Gem windows and sliding patio doors	Yes	No	Numerous standard and custom sizes in six colors, fitting most needs at an affordable price.
Andersen windows and sliding patio doors	Yes	No	Upscale Fibrex® frames for durability and strength, in numerous colors.
Pella windows and sliding patio doors	Yes	No	An upgrade option available nationwide.
Milgard aluminum windows and sliding patio doors	Yes	Yes	For matching the older aluminum windows on your home, which is common in California.
Codel or Therma-Tru fiberglass French doors (single and double)	Yes	Yes	Opens the room to the outdoors. Not recommended in high wind-and-rain areas without a larger extended eave.
Roof system and panelsCombined, these give a strong, durable, leak-proof roof lasting 50+ years
15″-wide roof panels	Yes	No	Easier installation.
2×6 rafters at 15″ on center	Yes	No	Meets or exceeds IBC for an exceptionally strong roof.
Standard R38 rigid-foam insulation, solid fill	Yes	No	Removes the need for venting and meets code in most places (a vented roof is available where required).
Optional 2×8 or 2×10 rafters	Yes	No	For larger structures or colder-climate energy-code compliance.
Electrical chase in every roof panel	Yes	No	Lets your electrician run wiring into the roof and ceiling easily.
Pine tongue-and-groove ceiling liner, pre-installed	Yes	No	A finished ceiling without the mess of sheetrock and paint.
Optional tight-knot cedar tongue-and-groove ceiling	Yes	No	A warmer ceiling finish, also without sheetrock and paint.
ACX plywood roof sheathing	Yes	No	Stronger and longer-lasting than typical OSB, which can chip or warp over time.
Water & ice shield underlayment	Yes	No	Meets or exceeds IBC and adds an extra layer of protection from the elements.
Nu Ray standing-seam snap-lock metal roofing	Yes	No	40-year warranty. Fasteners are hidden from the elements, panels snap-lock in place, and colors meet or exceed reflectivity standards.

Yes = included as standard. No = not typical of prefab sheds. Varies = depends on the vendor.
