Sustainable composite decking from TimberTech is a safer, longer-lasting, more environmentally friendly alternative to non-recycled traditional wood decking. Choosing sustainable building materials helps in more ways than you might imagine, including:

  • Improving the value of your home.
  • Improving the health of you and your family.
  • Contributing to the betterment of our planet.

Plus, homes built with green building practices, like using recycled materials, stay beautiful and sustainable, and are eligible for LEED certification. LEED, or Leadership in Energy and Environmental Design, is an international green building certification system, run by the U.S. Green Building Council (USGBC). As a USGBC Gold Member, we know the importance of sustainable building materials – and how opting for TimberTech composite decking benefits both your pocketbook and your health.

  • Low-impact, long-lasting products. Enhance your backyard with durable decking that doesn’t need the harmful chemical stains or sealants of traditional wood which release harmful volatile organic compounds (VOCs) into the air.
  • The beauty of real wood without the harm. Enjoy the nature-inspired beauty of TimberTech decking while avoiding the environmental harm caused by unsustainable logging.

LEED Certification: What It Means & How You Benefit

LEED-ing the Way

What: LEED recognizes commercial and residential buildings, as well as entire cities and smaller communities, for their commitment to sustainable building. The TimberTech headquarters in Chicago is a LEED-certified building, and our parent company, The AZEK Company is a USGBC Gold Member.

So What: The more sustainably you build a structure – office OR home – the more you help your budget, health, and planet.

Why LEED Certification Is Good for the Planet – AND You

And while our LEED-certified office aligns with our commitment to the planet, we’re also committed to you and your family’s health and wellness. TimberTech sustainable composite decking can therefore be an important part of transforming your house into a LEED-certified home.

How TimberTech Decking Helps
  • Energy: Our capped polymer decking remains up to 30° F cooler than leading competitors’ composite decking, reducing the amount of heat radiating off your deck into your home during the summer.
  • Improved value of your home. Homes with green certifications bring a higher price tag compared to their conventional counterparts.
  • Value: Having a gorgeous, low-maintenance, sustainable composite deck from TimberTech, backed by industry-leading warranties, will up your home’s curb appeal.
  • Improving the health of you and your family. LEED-certified homes require proper ventilation and restrict the use of harmful chemicals in paints and finishes to improve air quality so the whole family can breathe easier.
  • Health: No harmful stains or sealants are required for maintenance on a TimberTech composite deck, like they would be for traditional wood.
  • Contributing to the betterment of our planet. Homes with LEED certification reduce greenhouse gas emissions and use resources like electricity and water in more sustainable ways.
  • Environment: No need to use energy-consuming power washers or harsh chemicals to clean the deck. TimberTech DeckCleaner™ is non-toxic, bleach-free, and biodegradable for a safer clean – that doesn’t require any heavy-duty tools.

Lowering Landfill Contributions

Nearly 500 million pounds of scrap and waste was diverted from landfills in 2021 through our recycling program, which is expanding to do even more.

Traditional Wood

Unsustainable Materials

While you can use reclaimed wood, it is often more expensive than virgin wood due to extra work like sorting, testing for toxins, and removing embedded nails and/or contaminated organic material.

No Conservation

Traditional wood – and in particular, exotic hardwoods like Ipe – can contribute to deforestation and loss of habitats for endangered species.

Landfill Contributions

Wood decks in disrepair from rot or mold can’t be reused and are often discarded. In 2018, landfills received 12.2 million tons of wood.
