James Hardie invented fiber cement siding over 30 years ago and their products are now on more than 10 million homes across North America. There's a reason it became the standard. International Building Supply stocks James Hardie siding and trim at our Naugatuck yard for contractors and homeowners across New Haven, Litchfield & Fairfield County.
Most people know James Hardie by reputation before they know the product. Fiber cement is a mix of Portland cement, sand, and cellulose fibers pressed into boards and panels. It's heavier than vinyl, more rigid than wood, and the grooves are deep enough that it genuinely looks like wood siding at a glance. James Hardie's formulation includes proprietary additives that go beyond standard fiber cement. The result is a product that handles Connecticut's freeze-thaw cycles, humidity, and coastal exposure better than wood, vinyl, or composite alternatives.
Connecticut weather is genuinely hard on exterior materials. James Hardie fiber cement handles our climate because it was engineered to. It doesn't absorb moisture, doesn't rot, and doesn't warp through freeze-thaw cycles. It holds paint significantly longer than wood and meets fire codes that vinyl can't touch. Those aren't marketing claims. They're why architects and contractors specify it on project after project across the Northeast.
Their warranty runs 30 years and is non-prorated, meaning coverage doesn't diminish over time.
