INTEX Vs. Vinyl railings, what is the difference

What's The Difference & What Should You Choose

INTEX vs Vinyl Railings In Your New Home

When you look from across the street, INTEX railing and standard vinyl railing look almost identical. Both are white, low-maintenance and both replace the painted wood railings that used to rot out every few years on shore homes. But they’re two very different products, and the difference shows up fast on a barrier island. So whether you are building a new home in South Jersey or renovating an existing one and changing up the deck, here is everything you need to know about INTEX and Vinyl.
 
INTEX is a cellular PVC railing system with aluminum reinforcement built inside each component. Standard vinyl is a hollow PVC extrusion with exposed metal framing underneath. At McHugh Builders, we typically spec INTEX on our Brigantine custom homes. It costs more. It’s not always necessary. But for the conditions we build in, it’s the better product, and here’s why.

What Makes INTEX a Different Product

INTEX Millwork (now INTEX by Azek after the 2022 acquisition) manufactures cellular PVC railing systems. “Cellular” means the PVC is solid throughout rather than hollow. That distinction matters for two reasons: strength and weather resistance.

 

The aluminum reinforcement inside each rail and post is fully encapsulated by the PVC. Nothing is exposed to the elements. The fasteners are hidden stainless steel, so there are no screw heads or bracket faces sitting out in the salt air waiting to corrode and leave rust streaks down your post.

The finish is matte, not glossy. It looks like painted wood millwork rather than plastic. You can cut it, rout it, and drill it the same way you’d work with real wood, which gives us flexibility on custom builds where standard profiles don’t always fit. INTEX backs the product with a 25-year limited warranty and it’s code-approved for spans up to 12 feet.

If you’ve read our post on custom exterior features for coastal homes, you know we think about every exterior component as part of a system. Railing isn’t an afterthought any more than your deck edge detail is. Same philosophy applies here: the material you choose for railing affects how the whole exterior holds up and looks five, ten, fifteen years from now.

Where Standard Vinyl Still Makes Sense

We’re not going to tell you that every railing project needs INTEX.

Standard vinyl railing works fine in a lot of situations. A covered porch with minimal weather exposure. An inland home that doesn’t deal with salt. A rental property where the budget needs to stay tight and the railing just needs to look clean and meet code. Vinyl gets the job done at roughly half the material cost, and for those applications, it’s a perfectly reasonable choice.

The problems we see with standard vinyl show up in specific conditions: direct UV exposure over years, salt air, moisture getting trapped in hollow cavities, and the exposed metal framing that most vinyl systems rely on. If you’re building in a protected environment without those stressors, standard vinyl can last a long time without issues.

The Difference On Water-Front / Barrier Island Homes

Brigantine is not a low moisture town. It’s a barrier island with salt air hitting every exterior surface year-round. Wind-driven salt spray, summer UV, temperature swings from January to August, and the occasional nor’easter that puts everything to the test.

Here’s what we’ve seen happen with standard vinyl railing systems on coastal homes over time:

  • The hollow PVC yellows and becomes brittle, especially on south-facing elevations that take full sun
  • Exposed aluminum and steel framing underneath the vinyl caps starts to pit and corrode. Paint flakes. Rust bleeds through joints and down the face of posts.
  • Moisture works its way into hollow cavities and sits there. On older installations, you’ll sometimes find mold growing inside the railing components.
  • Exposed fastener heads corrode and stain the surrounding PVC. A few years in, you’ve got brown streaks on white railing that no amount of cleaning removes.

INTEX prevents all of that. The cellular PVC doesn’t have hollow cavities for moisture to collect in. The aluminum reinforcement is sealed inside the material where salt can’t reach it. The hidden stainless steel fasteners won’t corrode or stain. And the material itself is formulated to resist UV fading and won’t become brittle the way hollow PVC does.

Additionally, a fun fact worth mentioning: thermoplastic railing was literally invented at the Jersey Shore in the early 1990s to combat salt-air. The first systems installed are still standing and functional over 30 years later. The technology was born out of exactly this problem, because wood railing on shore homes was a maintenance nightmare, and it has only gotten better since which is exactly why each McHugh Built home opts for INTEX.

Which Should You Choose?

If you’re building or renovating on the coast and the railing will be exposed to salt air and direct weather, INTEX or a comparable cellular PVC system is the right call. If you’re working on an inland project, a covered porch, or a budget-driven renovation where longevity in harsh conditions isn’t the primary concern, standard vinyl will serve you well.

For our Brigantine builds, the answer is straightforward. We spec INTEX because it matches the quality standard we hold for the rest of the home. If you’re planning a build or renovation and want to talk through material choices for your specific project, give us a call at (609) 513-9269.

Commonly Asked Questions About Railings

Standard vinyl railing is made from hollow PVC extrusions. Cellular PVC railing (like INTEX) is solid throughout, with internal aluminum reinforcement. Both are technically PVC-based materials, but the construction and performance are significantly different, especially in harsh weather environments.
Standard vinyl railing can last 15 to 20 years in moderate conditions. In coastal environments with heavy salt and UV exposure, that lifespan shortens and you'll see yellowing, brittleness, and fastener corrosion well before the railing fails structurally. Cellular PVC systems like INTEX carry 25-year warranties and are designed to handle those conditions without degradation.

Make Your New Home Railing Last

Railing is one of those details that’s easy to leave until the end of a build and regret later. When we design a custom home in Brigantine or the surrounding shore towns, the railing system is specced alongside the decking, the exterior trim, and the structural engineering. Every material choice feeds into the next. The deck edge detail, the post mounting, the fastener spec, the railing profile. That’s how you end up with a finished exterior where every component holds up the same way and looks like it belongs together!

Give us a call at (609) 513-9269 or reach out through our website. Whether you’re building a new home from the ground up or renovating an existing one, we’ll walk through the material options for your project and make sure the railing matches the quality of everything around it.
