Knotwood Decking

In case you’ve been dreaming about grilling, dining, entertaining, or simply relaxing on a gorgeous deck in the security of your own lawn, we can make that little glimpse of heaven with a custom deck, planned and built by our master deck developers.

Enjoy your outdoor living with aluminum decking from Norman’s Overhead Doors, Inc. Why struggle with scraping, staining, sealing or painting wood, composite or pvc decking? Norman’s gives homeowners the freedom to enjoy their outdoor deck, rather than spending countless hours and money on deck maintenance and repairs.


Knotwood aluminum decking is an innovative interlocking design. It will not warp, rot, swell, or splinter like timber or composite decks.

Knotwood aluminum is low maintenance outside of periodic cleaning with soap and water. No need for constant upkeep of paint, stain, and oil. The decking surface is slip-resistant for safety and security. It’s durable with a tough texture coating and long-lasting with a 20-year warranty.

Knotwood aluminum decking is cool to the touch since aluminum has high thermal conductivity and rapidly dissipates heat, creating a cooler surface than most traditional decking materials.

My garage door broke and I scheduled with Norman’s Overhead Doors to repair my garage door. Jerame and Deven arrived and after looking at the door they suggested to change the door due to wood rot. They then showed/explained to me that wood rot was the root of the door problem. They changed the door, hauled the old door away, explained how to use my new door, and they cleaned up their rubbish. Although that is expected by every company, it was their customer service and knowledge that made my experience amazing and they went over and beyond. That’s why I took the time to write this comment!

Great service and customer service too! I was trapped when the spring broke and in a bind to get out to work. Arrived in great time and explained other options to maintain my door for a longer, better performing life!

My Mom's old garage door opener needed to be replaced. I talked to VAL around 10:00 AM, and JERAME showed up around 1:30 to begin the job. He was finished by 4:00 ....... New opener motor unit, new rail, new inside and outside switches, new safety lasers. The work was professional ..... very clean and tidy. I have used Norman's several times for repair, and will continue to use them in the future.

Knotwood Aluminum building system is a unique construction material that combines the natural beauty and timeless appeal of wood with the capabilities of aluminum. This system is designed to give you a wood-like appearance on your buildings while taking advantage of the durability and strength of aluminum.

Knotwood Aluminum has many advantages when compared to other building materials. It’s lighter than most materials and offers greater durability and resistance against elements. It doesn’t rust, warp or require regular maintenance like wood does. It is also resistant to insects, such as termites which makes it a perfect choice for any kind of outdoor and indoor constructions.

Knotwood Aluminum is versatile and can be used in a variety of applications in construction. It is often used for building exteriors because of its durability and weather resistance. It can also be used for interior applications, as it doesn’t emit VOCs (Volatile Organic Compounds) like some other materials. This includes decking, fencing, cladding, gates, screens, and more.

Aluminum is one of the most environmentally friendly metals, it’s 100% recyclable and reuses most of the original metal during the recycling process. Knotwood’s process also uses less energy than traditional wood or metal fabrication. Moreover, it reduces deforestation by offering an alternative to traditional wood construction materials.

One of the major advantages of using Knotwood Aluminum is that it usually requires very little maintenance. Unlike wood, it doesn’t need to be regularly sealed, painted or treated. Just a simple clean with a mild detergent and water usually suffices. Knotwood Aluminum is also resistant to corrosion which makes it last longer.
