Maximizing Energy & Style: Exploring the Benefits of Insulated Vinyl Siding

Not all vinyl siding is created equal. Depending on material, technology, manufacturing processes, and other factors, vinyl siding comes in a range options and price points that vary in both performance and aesthetics. Among those options is insulated vinyl siding, which, just as it sounds, is vinyl siding with a foam backing that can help enhance both the appearance and the thermal insulation value of the home.

What’s Unique About Insulated Vinyl Siding?

The insulation board on the back of CraneBoard® Solid Core Siding® from Westlake Royal Building Products™ is just 1-1/8-inch inch thick, but it packs quite a benefit punch.

High-End Aesthetics

You can notice the difference from the curb: Because the insulation backing provides for a more robust, stiff panel, CraneBoard comes in wide, architecturally correct 6-inch and 7-inch panels for a truly authentic cedar look and in 12-foot and 16-foot lengths for fewer seams. The rigid panel helps straighten walls for a clean, smooth finished appearance.

Along with the wider profiles, CraneBoard also is available in Quad 4.5-inch Dutchlap and Board & Batten styles to meet any design aesthetic.

Improved Thermal Performance

Insulated vinyl siding wraps the home’s exterior in a layer of continuous insulation, helping to reduce what’s called “thermal bridging.” This phenomenon occurs when heat and energy escape the house through the pathway of the house framing, which, unlike a wall cavity, is not insulated. By collectively covering those framing studs with foam insulation, insulated vinyl siding helps dramatically reduce heat loss.

You can see how this works in this side-by-side comparison using a thermal imaging camera. On the left is a house without insulated vinyl siding. The yellow area shows how heat transfers through the studs. On the right is the same house with CraneBoard siding; CraneBoard, shown in blue, cuts down on the energy lost through the studs of the home’s walls.

Thermal bridging of regular siding vs. insulated siding

As a result, CraneBoard Solid Core Siding offers significantly more insulating power than fiber cement, wood, engineered wood, or brick.

Noise Reduction

The foam insulation backing on CraneBoard also helps reduce the transmission of external noise, contributing to a quieter interior.

Moisture Management

CraneBoard Solid Core Siding is the only insulated siding with the Smart Track™ system with moisture management ridges, which helps water that may be behind the siding (due to wind-driven rain or through vapor coming through the wall assembly) to escape.

CraneBoard Insulated Vinyl Siding Offers Color That Lasts

Along with the added value the insulation brings, CraneBoard Solid Core Siding offers a range of additional benefits that contribute to longevity in form and function.

Unlike wood, engineered wood, and fiber cement, CraneBoard siding doesn’t require periodic caulking or repainting. It features Chromatix® technology color protection to help

effortlessly maintain the original look. In fact, the use of Chromatix technology enables Westlake Royal to warranty fade to as low as 4 Hunter Units (a common measure of color difference). (Read more about this here.)

So whether your customers are seeking the richness of Lighthouse Red, the brilliant blue of Indigo, or the cozy appeal of Greystone, they can count on color the lasts, siding that is easy to maintain, curb appeal the endures—and the added power of insulation.

25 Years of Vinyl Siding Certification

The Vinyl Siding Institute recently marked the 25th anniversary of its Product Certification Program, an important tool for buyers and specifiers to identify siding materials that are code compliant and high quality. Products listed under VSI’s Product Certification Program are tested and validated by an independent ISO/IEC 17065 accredited third-party certification body to deliver superior protection and meet and exceed international code standards.

“The program’s goal was standardizing the industry as a whole so that all manufacturers were on a level playing field and that products were consistently produced and distributed to the standards established,” explained Sara Krompholz, VSI’s senior director of technical and certification. “The program was also designed to achieve greater consumer confidence.”

VSI Certified Products provide quick, at-a-glance verification of code compliance, eliminating the need for specifiers to research manufacturer documentation. The products also are tested and proven to stand up to harsh conditions. The program certifies traditional vinyl siding, insulated vinyl siding, and polypropylene siding.

The Evolution of Vinyl Siding Certification

According to VSI, the organization has continued to expand and refine the Certified Products Program as the market has required. This includes adding standards for color in 2006 and adding wind-load testing in 2008. And in 2021, VSI relaunched the program as an independent third-party program with ISO/IEC 17065 accreditation, with Intertek as the certification body. With this change, products in the program must carry a Product Certification Listing (PCL) declaring that it complies with recognized standard. An optional Product Evaluation Report (PER), which denotes that a product meets recognized standards and requirements for building codes, is also available.

VSI says it will continue to evaluate, refine, and adapt the Product Certification Program as it moves forward. “The sky’s the limit,” said Krompholz. “We are continuing to evolve and expand our scope as evidenced by the addition of backed siding. We are working on recognizing Canadian certification to the National Building Code of Canada (NBC). In the future, we might consider adding accessories and other PVC-related materials, and a scheme has been written to allow us to include expansion opportunities, which could also expand membership.”

Inspiration: 6 Approaches to Create Compelling Gable Ends 

Multi-textured facades are one of the most popular trends for residential exteriors, and gable ends are an easy way to add differentiation and styling.

Foundry™ Specialty Siding and Portsmouth™ Shake & Shingles offer the warm look, deep textures, and rich colors of cedar in a range of authentic shake and shingle profiles—ideal for accents or the full façade. In addition, both are available in a single-course 7” to minimize waste in a gable application.

Consider these approaches to using shakes and shingles for more eye-catching gable ends:
Two-tone colors: Incorporate gable siding in a color one or two shades removed from the rest of the façade. The siding profile can be the same or different than the main cladding. Shown here are Portsmouth D7 Cedar Shingles in Oceanside and Indigo, as well as Exterior Portfolio™ Vinyl Trim in Aspen White.

On this home, Foundry Split Shake siding in Colonial Grey in the gables combines with a slightly darker tone on the main façade.

• Matching colors, unique profiles: Blending shakes and shingles in the gables with lap siding or other profiles on the main façade offers a subtle yet eye-catching look. This home achieves this with Foundry 7” Split Shake in Blueberry 253.

• Contrasting colors: Adding a bold color to the gable can provide a more dramatic pop of color without a huge commitment on the full façade. When choosing, select accent colors that work well with the main siding. As explained on Color Matters, “color harmony” can be achieved by using a color wheel and choosing analogous colors (three colors side by side on the wheel) or complementary colors (directly opposite each other on the wheel).

Shown here are Portsmouth D5 Cedar Shingles in Greystone above D5 Cedar Shingles in Driftwood.

This home features Foundry 10” Staggered Shake in Russet over a tan facade.

• Board and batten: For an on-trend style combination that adds a touch of distinction, incorporate board-and-batten into the gable. This Craftsman stands out and veers slightly modern with two small Portsmouth Board and Batten accents in Sand, above D7 Cedar Shingles in Storm for the main façade.

• Specialty shapes: For traditional homes, specialty shapes like Portsmouth Half Rounds (shown here in Cypress) add a touch of flair in keeping with the familiar style.

Gable vents: Easy-to-install gable vents are the perfect decorative element for gables, and come in simple shapes or designer options. Choose from a coordinating color or a bolder accent. Shown here is a Mid-America™ half-round gable vent.

Vinyl Siding: A Surprising Way to Go Green

Exterior Portfolio vinyl siding

Most people don’t consider vinyl an eco-friendly building product, but data show it actually is. There are misconceptions that vinyl siding doesn’t have sustainable design, production, or operations. But vinyl outperforms almost all other common cladding materials, including fiber cement and brick, in total environmental impact.

While the classic look of wood is forever timeless, new developments in design allow vinyl siding to look and feel like real wood, down to the actual grain. With vinyl, you can eliminate the cost and maintenance of wood and choose a sustainable, durable, and affordable alternative. If you, your company, or your customers are dedicated to greener construction and building practices, then vinyl siding is for you.

Less Waste

From production to construction, vinyl siding produces less waste than other building materials, such as brick and cement. Vinyl siding products require minimal raw material and produce virtually no waste. They also require less water and energy to produce than other building materials.

Lower Impact

Vinyl siding also maintains a low environmental impact over its lifespan. The National Institute of Standards and Technology (NIST) developed Building for Environmental and Economic Sustainability (BEES) software to measure specific environmental concerns such as air pollution, acidification, and global warming potential in the environmental life cycle of products.

Throughout its life cycle, vinyl releases significantly fewer toxic chemicals into the environment than other siding materials and has a lower overall environmental impact.

Compared to vinyl siding, construction materials like fiber cement contribute 4x to global warming potential, 2x times to acidification, and over 3x to air pollution. Compared to other common sidings, vinyl performs amazingly well. According to the NIST, vinyl has a lower environmental impact than brick, and even rivals some wood siding.

Westlake Royal Building Products uses PVC resin as the backbone of Royal and Exterior Portfolio vinyl siding. This is derived from components in nature, such as common salt and natural gas, that make PVC weather-resistant, chemically stable, and lightweight.

Recyclable

While some argue that wood is a more eco-friendly siding option because it is biodegradable, vinyl siding lasts longer and is recyclable. Vinyl siding is recycled with post-consumer recycling, post-industrial recycling, and closed-loop recycling, meaning every part of its production and lifespan lends it to being easily reused.

Recycling reduces waste disposal and extraction of new materials while reducing landfill accumulation and incineration. Both lead to an increase in greenhouse gas emissions. Because of the nature of PVC, vinyl is a thermoplastic that can be ground up repeatedly, re-melted and formed into various new products even after the life expiration of the original product.

According to the Vinyl Siding Institute, 99% of scrap in manufacturing is recycled into other products rather than being sent to the landfill.

Longevity

The longevity of vinyl siding is part of what makes it so eco-friendly. Although recycling is an important component of sustainability, vinyl lasts such a long time it is unlikely to end up in the waste stream anytime soon. Many warranties on vinyl siding last for 40 years or more, meaning it doesn’t have to be ripped out and replaced very often.

Not only is vinyl long-lasting, but it’s low maintenance. Exterior siding that requires less care saves resources and reduces emissions and chemicals.

Thanks to innovative technology and sustainable practices, PVC vinyl siding is perfect for giving homeowners the aesthetic and performance they are looking for, while offering the peace of mind that our products were purpose-built to support a sustainable alternative and future.
