IRONGRAIN Ushers In The Next Generation Of Outdoor Living: Why Thermally Modified Wood Beats Pressure-Treated and Composite Decking

For decades, homeowners choosing outdoor decking materials faced a frustrating compromise. You could opt for the authentic beauty of natural wood—knowing it came with heavy chemical content and a lifelong chore list of staining, sealing, and replacing warped or splintered boards. Or, you could choose plastic composite materials—trading real wood texture for lower maintenance, while accepting artificial finishes, high surface temperatures, and petroleum-based synthetic components.

IRONGRAIN Thermally modified wood decking changes the equation entirely and is ONLY available at GNH Lumber & Home.

By subjecting sustainably harvested lumber to a chemical-free heat-and-steam process, IRONGRAIN thermally modified wood delivers the genuine warmth and organic character of real timber combined with modern durability. It consistently delivers The Soul of Wood and The Strength of Iron.

Here is how IRONGRAIN compares to traditional pressure-treated lumber and synthetic composite decking.

What Is IRONGRAIN?

IRONGRAIN uses the thermal modification process to “cook” ash boards in specialized kilns at extreme temperatures (often between 350° and 420° using heat and steam.

This process alters the cellular structure of the wood at a molecular level:

• Eliminates Organic Food Sources: The heat cooks out the natural sugars, starches, and nutrients that rot-causing fungi, mold, and wood-boring insects feed on.

• Reduces Moisture Absorption: The process permanently reduces the wood’s equilibrium moisture content down to roughly 4%–6% (compared to 12%–19% in standard lumber).

The Result is IRONGRAIN – Real solid wood that naturally resists decay, rot, and insects—without adding toxic chemicals or synthetic resins.

Thermally Modified vs. Pressure-Treated Lumber

Pressure-treated (PT) wood has long been a go-to budget option for deck building, but it comes with known performance limitations.

Pressure-Treated: High Moisture Content – Swells, Warps, Splinters Easily
IRONGRAIN: 4-6% Moisture Content – Exceptional Dimensional Stability

Dimensional Stability                 Highly stable – minimal swelling or shrinking.         Prone to severe cupping, twisting and shrinking
Splintering & Comfort                Smooth underfoot & virtually splinter-free                Splinters readily over time as it dries
Environmental Impact               Fully biodegradable & non-toxic                                  Chemical disposal issues at end of life

Why IRONGRAIN Wins:

Traditional pressure-treated boards are injected with water-based chemical solutions under pressure. As the boards dry out on your deck under direct sunlight, they release that moisture rapidly, leading to warping, checking, twisting, and painful splinters.

Because IRONGRAIN has already had its cell structure permanently baked into a stable state, it exhibits superior dimensional stability. It stays flat, tight, and true season after season—regardless of heavy rain, snow, or humidity shifts.

IRONGRAIN vs. Composite Decking

Composite decking (a mixture of recycled plastics and wood flour) gained popularity by promising low maintenance. However, IRONGRAIN outperforms synthetic composites in several key operational and aesthetic areas:

1. Heat Retention (Barefoot Comfort)

• Composite Decking: Plastic-capped composite boards act as thermal sponges. In direct sunlight, composite surfaces can reach scorching temperatures 140° – 160°, making them uncomfortable or unsafe for bare feet and pets.

• IRONGRAIN: Wood is a natural thermal insulator. IRONGRAIN stays noticeably cooler under direct summer sun, allowing for comfortable barefoot walking even during July heat spikes.

2. Authentic Aesthetics & Natural Aging

• Composite Decking: While modern composites mimic wood grain, they still present a repetitive pattern and plastic-like sheen. If a board gets deeply gouged or scratched by patio furniture, repairing it is difficult and replacement boards may not match due to faded dye lots.

• IRONGRAIN: Every board features genuine, non-repeating wood grain with rich, deep brown tones baked all the way through the core. If scratched, it can be sanded or spot-treated. Left untreated, it ages to a silvery-grey patina without losing its structural integrity.

3. Eco-Friendly Sustainability

• Composite Decking: Although often made with recycled components, composite decking relies heavily on petroleum-based plastics. At the end of its lifespan, composite boards cannot be easily recycled and typically end up in landfills.

• IRONGRAIN: Sourced from responsibly managed, renewable forests. The modification process uses no toxic chemicals or synthetic binders, making it a sustainable, carbon-sequestering building material.

The Bottom Line: IRONGRAIN = Real Wood & Modern Performance

IRONGRAIN decking bridges the gap between natural timber and synthetic alternatives. It provides:

• The natural beauty and cool-touch comfort of real timber.

• The rot, insect, and decay resistance required for outdoor environments.

• The dimensional stability needed to avoid warping, cupping, and splintering.

For homeowners and builders seeking a natural, sustainable outdoor space built to last, IRONGRAIN delivers long-term durability without sacrificing authentic wood character.

Memorial Day weekend marks the unofficial start of summer in Upstate New York. It’s the long-awaited weekend when we can finally throw open the windows, fire up the grill, and gather our families on the deck after a long winter.

Whether you are hosting a large family barbecue or looking forward to a quiet weekend with the kids, Memorial Day is about two things: honoring the families who made our freedom possible, and celebrating the home front they fought to protect.

If you are planning a get-together this weekend, a few simple, high-impact projects can turn your backyard into a welcoming oasis for your guests. Here is a quick guide to getting your home host-ready for the holiday weekend.

1. Refresh Your Outdoor Living Space

Your deck or patio is the main stage for Memorial Day weekend. Before the guests arrive, give it a quick face-lift.

• The Deep Clean: Start with a thorough sweep and a power wash to eliminate dirt, pollen, and winter grime from your decking and outdoor furniture.

• A Pop of Color: A fresh coat of exterior stain on an weathered deck or a quick weekend paint project can completely transform your backyard. Group your outdoor seating around a central point, like a fire pit, to create a natural conversation area for family members to catch up.

2. Fire Up the Grill Station

The heart of any Memorial Day gathering is the food. If your grill has been sitting idle, take an hour ahead of the weekend to get it prime condition.

• Safety and Cleanliness: Clean the grates thoroughly, check your burners, and ensure your propane tank is full (or you have plenty of charcoal on hand).

• The Ultimate Setup: Elevate your cooking space by setting up a prep table nearby. Having your tools, spices, and platters within arm’s reach means the cook gets to spend less time running back and forth to the kitchen and more time playing cornhole with the family.

3. Create Ambience for the Evening

A great family get-together easily stretches from a sunny afternoon into a cool May evening. Keep the party going comfortably with the right lighting and warmth.

• Landscape Lighting: String lights across the deck or place solar path lights around the yard to create a warm, inviting glow as the sun goes down.

• Gather Around the Fire: A permanent or portable fire pit is the perfect destination for the end of the night. It provides the ideal backdrop for roasting marshmallows with the grandkids and sharing old family stories.

A Quick Project Tip: Don’t let a long to-do list get in the way of enjoying your family. Focus on the high-visibility areas where people will naturally gather—the deck, the grill, and the seating area.

Celebrate the Weekend

When Monday arrives and the flags are raised, the most important part of the weekend isn’t the perfection of the renovation or the stain on the deck—it’s the people filling the space. Memorial Day reminds us that our homes are sanctuaries for the people we love.

From our family to yours, have a safe, happy, and meaningful Memorial Day weekend!

In the Catskills, Capital District, and the Hudson Valley, the first true scent of spring isn’t just the blooming lilacs—it’s the smell of cedar, freshly turned soil, and the first weekend of outdoor prep. After a long winter, our decks and patios aren’t just additions to our homes; they are a welcome invitation to live outside for the next five months.

Whether you are looking to revitalize an existing deck or planning a complete backyard transformation, the secret to a successful outdoor season is getting a head start in May.

Audit Your Deck: Safety First

Before you host your first BBQ, a thorough inspection of your deck is essential. Our region’s winter weather can wreak havoc on hardware and wood.

• The Hardness Test: Take a screwdriver and gently press it into several areas of your wood decking, especially where boards meet the joists. If it’s soft, it’s time to talk about replacement.
• Hardware Check: Ensure the ledger board (where the deck attaches to the house) is secure.
• Upgrade Opportunity: If your wood deck is showing its age, this is the year to consider thermally modified or composite decking like TimberTech. Products like our high-performance decking lines offer the beauty of real wood with the stability of a material that won’t warp or twist under the summer sun.

Inspect your deck before the season

• Pressure Washing: The key here is to apply presoaking/cleaner and use the right setting on your pressure washer. Using the highest setting will damage your deck, so make sure your pressure washer is on the lowest setting, use the 40° nozzle, and hold the nozzle about 12″ – 18″ above the deck, moving with the grain.
• Brushing: If you don’t have a pressure washer, a specialized deck cleaner and a stiff-bristle brush can do a great job of lifting gray oxidation without damaging the wood fibers.
• The Benjamin Moore Advantage: If your deck is looking faded, a fresh coat of Woodluxe can do more than change the color—it provides the UV protection needed to prevent splintering. For a modern look, consider a solid stain in a deep charcoal or slate gray to make your greenery pop.

Not Just A Deck, It’s Another Room

One of the biggest trends in home improvement is treating the backyard as a literal extension of your interior floor plan. More than ever, this means thinking about your layout:

• The Cooking Zone: Is your grill area functional? Consider adding some countertop space or a custom-built outdoor kitchen island for prep work.
• The Conversation Zone: Arrange your furniture to encourage conversation. Use outdoor rugs to define the space and outdoor lighting like Edison bulbs or recessed deck lights to extend the “usability” of the room well into the evening.

Privacy & Personalization

Your outdoor space should feel like a sanctuary. If you have neighbors in close proximity, consider architectural measures to enhance privacy.

• Lattice & Screens: A simple cedar lattice or a modern horizontal slat wall can look nice while providing privacy without blocking the breeze.
• Create The Perfect Connection: Look at your home from the outside in and create a seamless transition. Replacing a standard back door with a Marvin sliding or folding door system can completely erase the barrier between your kitchen and your deck, making your outdoor space feel twice as large.

Keeping your deck private

The GNH Design Kickstart

One of the most common mistakes homeowners make is waiting until the first 80°C day to start their outdoor living projects. By then, material lead times and contractor schedules are at their peak.

By starting your outdoor audit in May, you ensure that when the Fourth of July arrives, you aren’t standing in a construction zone—you’re sitting in an outdoor living space you’ve always dreamed about.
