Nonwovens remain constant in the building and construction market. While you don't usually see them, nonwovens play a huge role in new construction and renovations of existing buildings and homes - they are used in house wrapping, roofing, window flashing, thermal and acoustic insulation, and many other areas. part. Manufacturers of nonwoven materials and composites are optimistic about the future of nonwovens in this market. Let’s take a look at the analysis and judgment of some industry leaders on the market.

Freudenberg Performance Materials Group

Freudenberg Performance Materials, the Freudenberg Performance Materials group, says it has a 40% market share in the roofing industry, but also sees the growing use of nonwovens in construction applications and the market continues to develop products that add value to the end user. The company believes composites are improving the construction market. "A new generation of 'composite technologies' is opening up new applications to improve the protection of construction fabrics and the quality of life in living areas," said Dr. Frank Heislitz, CEO of Freudenberg Performance Materials Group, adding, "Green" The strong development of construction provides further energy for the building materials market. End users are increasingly demanding sustainable products, with a clear preference for eco-friendly alternatives and recycled materials.

In this case, the Freudenberg Group is up to the task. The company's production process begins with recycling post-consumer PET bottles, its primary raw material, which is selected, washed and made into plastic masterbatches. The plastic masterbatch is then converted into short fibers, or directly used in the spunbond process to make recycled polyester nonwovens. "Recycling PET bottles means that we can replace virgin raw materials with recycled polyester of the same quality, allowing us to save natural resources," explains Heislitz.

Because non-woven fabrics can combine good mechanical strength with high elongation, polyester non-woven fabrics are the most commonly used carriers. In Freudenberg's reinforced products using glass filaments, the flexibility of polyester combined with the stability of glass gives nonwovens excellent handling properties. Heislitz adds, “This is especially true when used at high temperatures and on high-speed asphalt production lines, where the asphalt membranes have excellent dimensional stability and long-term durability.”

According to Heislitz, Freudenberg's leadership in the roofing market is due to the company's long-term positioning and strong customer relationships built on the company's deep understanding of customer needs and expectations. Advanced technology, flexibility and a broad product portfolio enable it to meet the most demanding customer requirements. “While invisible, once embedded in bituminous membranes, our polyester carriers are critical to our customers achieving their target product performance,” he said.

Currently, Freudenberg believes that there are generally positive expectations in the construction market, and further growth is expected in the medium term. In terms of specific growth areas, the company believes that developing countries have great potential for non-woven applications.

Owens Corning Owens Corning Continues to Expand

Owens Corning offers fiberglass products ranging from fiberglass to glass mats for residential roofs, coated and uncoated specialty nonwovens for residential and commercial buildings. Its research results are reflected in advanced technologies in the manufacture of glass fibers, glass coatings and non-woven mat composites.

Nico Del Monaco, European vice president, Nonwovens and Glass Reinforcements at Owens Corning, said the company is seeing growth in the nonwoven construction market across all regions, benefiting from growth in residential and commercial construction as well as these markets. Shift to composite materials. “Composites are reshaping the construction market, shifting the construction paradigm from the use of standard materials to high-performance products and systems through glass reinforcements and specialty nonwovens. We expect this trend to continue.”

Owens Corning is developing new solutions to support future penetration of composite materials into new markets. “One example is the ongoing shift in the construction market from paper and felt to nonwoven solutions,” adds Del Monaco.

According to Del Monaco, Owens Corning's non-woven fiberglass mats are typically produced by a wet-laid process on an inclined wire former, after which they are impregnated with a synthetic water-based binder, and the impregnated roll is dried and heated in a gas-heated Cured in belt dryer. After passing the inspection, it is cut and wound on the cardboard core in a turret winder.

Owens Corning uses its proprietary Advantex glass formulation, which is corrosion-resistant and boron-free. Typical binders include acrylic, urea formaldehyde and renewable organic binders. "Increased urbanization trends and greater demand for housing mean the market and demand for composite solutions," Del Monaco said. “People are looking to improve indoor air quality, save energy and increase sustainability more broadly, and our range of organic binders is replacing products that use formaldehyde binders.”

According to the company, composite products offer not only aesthetic advantages; performance advantages are significant due to the specialty nonwoven solutions offering fire resistance, mold and mildew resistance, enhanced acoustic performance, impact resistance, corrosion resistance, and more.

"Owens Corning's products often offer unique features," Del Monaco said. "Replacing the paper surface on the outer sheath of drywall with glass nonwovens is a good example. Paper surfaces have moisture and mold issues, so Owens Corning worked with the gypsum manufacturer to develop a specially coated glass nonwoven Spinning cloth solves these difficulties and improves the overall performance of the system. In addition, our gypsum panels allow the building to function normally during construction.”

Lately, Owens Corning has been in expansion mode. In April 2018, Owens Corning completed the

Acquisition of Guangde Shida Rock Wool Co., Ltd., which produces mineral wool insulation for the construction and technical insulation markets. Due to its fire-resistant properties, mineral wool is the main insulation material in China.

“We see a great opportunity to provide Chinese customers with products in the mid-temperature architectural and high-temperature industrial application markets. This acquisition furthers our strategy to expand Owens Corning’s technology portfolio in three of the world’s three largest insulation markets,” Insulation President Julian Francis said in a statement. stated at the time of acquisition.

The company currently has seven insulation manufacturing plants in China and is able to provide customers in the region with a full temperature range of products including fiberglass, extruded polystyrene foam, foam glass and mineral wool insulation for construction. Other Owens Corning investments include a specialty glass nonwovens facility in Gastonia, North Carolina, in 2016, and the acquisition of a glass-based coatings facility in Blythewood, South Carolina, in 2017.

Fibertex focuses on roofing materials

Fibertex Nonwovens works closely with some of the largest industrial roof manufacturers. It is constantly expanding its product range, and part of that is creating solutions that make installation on the job site as easy as possible. One of these innovations is a unique solution with a self-adhesive nonwoven specially designed for flat roof membranes. Fibertex's nonwovens are laminated on the back of waterproofing membranes for flat roofs, industrial or commercial buildings. The nonwoven acts as a protective membrane for the membrane and acts as a barrier between the roof and membrane. Additionally, the nonwoven material imparts tensile strength and elongation to the film.

For roof liners, Fibertex nonwovens are laminated with films. The goal is to create breathable materials that sit under the tiles, which are nailed to the roof. In this area, Fibertex nonwovens are advantageous because of their high tensile strength and high tear resistance. Meanwhile, Fibertex's non-woven fabric, called Absorex, is laminated on the back of a single metal sheet before molding, and Fibertex's non-woven fabric acts as an anti-condensing water droplet.

"Fibertex Nonwovens offers the perfect compromise between a soft textile material and high tensile strength," said Thomas Boudailliez, business manager for architectural floors. "Our non-woven products combine the advantages of lightweight and strong materials, which are a perfect match for new installation techniques."

According to Fibertex, the roof construction market has been expanding in recent years and this is expected to continue. "Market growth is driven by demand from Europe and the US for easier and faster installation of roofing materials," Boudailliez said.

DuPont adds to Tyvek portfolio

DuPont DuPont's Tyvek is basically synonymous with building envelopes - it was invented more than 30 years ago, but the company is constantly developing new products and making improvements to its existing product line.

In the roofing segment, the company recently developed the DuPont Tyvek Protec roofing underlayment for the residential construction market. Introduced in 2016, this product provides industry-leading walkability, which refers to the amount of grip a surface can provide when an installer is walking on a roof, as well as the proper amount of grip on a roof deck, DuPont Performance Building Solutions Roofing Business is responsible for Man Rupa Kibbe said. “Another feature of the Tyvek Protec product is the tiling nature of its use, which is critical for increasing productivity and ensuring that the underlayment is evenly installed on the roof deck,” Kibbe added.

Among other new product launches, the DuPont Tyvek DrainVent Rainscreen, launched late last year, is designed to provide advanced moisture protection for exterior wall systems. The product is DuPont Safety & Construction's first wind and moisture barrier membrane roll that creates a 6mm (0.25") space for drainage and air flow for drying after the enclosure.

The Tyvek DrainVent can be installed behind stucco, stone veneer, brick, wood, fiber cement and sheet metal, helping to extend the life of exterior cladding by creating gaps that help prevent rot, cracking and peeling problems. This product replaces the intermediate layers required for stucco and stone, while the additional heavy duty filter fabric prevents penetration of plaster and stucco.

The Tyvek DrainVent is easy to cut and install, lays flat and rolls around corners, helping to prevent improper installation and errors in detail. Heavy-duty filter fabric keeps grout out, helps create a flat surface that allows the cladding to lie flat, and has a high perm rating so it's very breathable. It also provides uniform non-structural support for various claddings due to its unique three-dimensional honeycomb textured design and durability.

If they are well designed, Kibbe said, nonwovens may enhance the properties of a product. “Just because a product is nonwoven doesn’t mean it’s ideal, or performs well. DuPont has chosen to combine nonwoven technology with textile technology to provide desirable physical properties.”

According to Kibbe, new construction growth has been slow as macroeconomic conditions such as mortgage rates and student loan debt continue to hamper potential first-home buyers. “However, the remodeling market has grown 50 percent since 2010, and as homes continue to age, we will see growth in the re-roofing business. DuPont is delivering on this growth by providing homeowners with innovative roofing solutions.”

Texel's acupuncture products are successful in the market

Texel Technical Materials has been involved in the building materials industry for nearly five years. It has played a role in different market segments including acoustic flooring, roof mesh, acoustic ceiling and wall applications. According to Texel business unit manager Alex Alexis, the company's sales growth is directly related to the demand for acoustic solutions and technologies to replace asphalt roofing technology.

“Needle punched nonwovens have proven to be highly efficient for acoustic technology,” Alexis said. “Previously, needle punch technology was used discreetly behind floors and walls, but the trend is to use needle punch technology to achieve both aesthetic and acoustic performance. ." For roofing, Texel's needle-punched nonwovens are used as reinforcements for liquid applications, flash systems and tile technology, replacing some stitching materials and fiberglass nonwovens. "Needling technology can provide good elongation properties at a cost-effective cost," he added.

In 2016, Texel was acquired by Lydall, a leader in specialty engineered products and materials, now part of the Lydall Technical Nonwovens division. In this group, Texel and Gutsche, the German needlepunched nonwovens company acquired that year, and Lydall are bringing their technical knowledge together. "This new synergy allows us to improve technology transfer and market knowledge," Alexis said.

Known as Audiovel, Gutsche acoustic nonwovens have a growing market share in Europe and North America. At the same time, Texel's new product line Feltkütur will show up more in North America. "This new synergy should provide better global reach and should accelerate the development of new acoustic panel technologies," explains Alexis. Feltkütur from Texel is a range of sound-absorbing panels made from a 100% PET blend. These acoustic panels are rigid and are used for ceiling and wall partitions. For the roofing business, Texel has developed a 100% PET fluff pulp for liquid applications. The product has strong absorption and capillary action. "Our line has been adapted to produce this product," Alexis said.

Texel is keen on the role of needlepunched nonwovens in the construction market. "The building materials segment has grown rapidly within Texel over the past three years," Alexis said. "We want to keep this growth going as needlepunch gains more market share in the roofing industry, and we're also seeing more North American government spending on infrastructure, which will impact our industry for years to come.
