Preflex, led by CEO Gabriel Grossman, has pioneered an innovative solution for energy-efficient and sustainable housing. The company's construction panels, resembling an Oreo cookie with a polystyrene core sandwiched between wood-like material, offer significant advantages in cost-effectiveness and energy efficiency, making them an ideal choice for sustainable homes. Additionally, Preflex is expanding into the accessory dwelling unit (ADU) market, providing prefabricated buildings using their cutting-edge panels.
Preflex's goal is to simplify the construction process for clients by offering pre-designed floor plans, as well as customized options to meet individual preferences. Grossman highlights that the company manages the entire process, from securing permits to assisting with financing arrangements, ensuring a seamless experience for homeowners. Preflex-trained contractors provide more than just panel installation; they offer a full turnkey service, allowing homeowners to move in or lease out their properties without additional hassle.
An exciting milestone for Preflex is the selection of their panels for a forthcoming Oceanside condominium project. This will be the first multi-family construction project to utilize Preflex panels for both interior and exterior walls. Chris Hall, president of Hallmark Communities, expressed enthusiasm for the partnership, emphasizing the benefits of reduced labor requirements and faster construction times when compared to traditional methods. The offsite fabrication of Preflex panels minimizes concerns such as parking and construction noise, streamlining the building process and enhancing efficiency.
Preflex's growing portfolio includes notable projects such as an Encinitas duplex, a four-plex in Golden Hill, and an ADU in Escondido. Since its founding in 2019 by Grossman and his partner Leopoldo Hirschhorn, Preflex has operated primarily in California, while also serving clients in Nevada and New Mexico. The panels are manufactured in Tijuana, Mexico, and shipped to construction sites, optimizing timelines and allowing homeowners to move into their new homes more quickly.
In addition to time savings, Preflex panels offer significant environmental benefits. The precision of the factory pre-cutting process reduces material waste, aligning with Preflex's commitment to sustainability and minimizing landfill waste. This eco-friendly approach ensures that the company’s operations contribute to preserving the environment.
Homes constructed with Preflex panels experience a notable reduction in energy consumption for heating and cooling, thanks to the panels' superior insulation properties. Grossman describes these homes as "living in a giant cooler," emphasizing their energy efficiency. Compared to traditional insulation materials, Preflex panels have a minimal environmental impact, as they are free of formaldehyde and effectively reduce noise transmission, creating a peaceful living environment.
One of the most striking advantages of Preflex panels is the time-saving benefit. Framing a building with Preflex panels can be completed in just one day, compared to the two to three weeks typically required for conventional construction methods. This remarkable time-saving not only boosts efficiency but also accelerates project completion, benefiting both builders and homeowners.
Preflex's groundbreaking construction panels have transformed the sustainable building industry. The panels offer multiple benefits, including reduced construction costs, energy efficiency, streamlined construction processes, and minimal waste production. As Preflex continues to drive innovation and environmental consciousness, it is clear that the company is shaping the future of construction, paving the way for more sustainable and efficient building practices for years to come.
