Nudura ICF vs. Wood Framing
The question is…Why wood you?
Nudura ICF Forms are high-tech industry-leading insulated concrete forms that have proven technologies to make building easier and faster. The Nudura line of ICFs offers innovation that is exclusive to Nudura, which allows builders the ability to build and design structures with greater efficiency.
Offering superior performance when it comes to thermal bridging, resulting in even temperatures throughout your home with reduced drafts and cold spots, ensuring you are comfortable no matter what the temperature is outside by providing Performance Values saving building owners up to *60% in annual energy costs. ICF also acts as an effective sound barrier by dampening sound vibrations from unwanted outside noise, such as traffic, trains, and neighbors.
ICF walls are built with reinforced concrete and fire-retardant Expanded Polystyrene Foam (EPS), providing a fire protection rating of up to 4 hours – 4 times that of a typical wood-frame home.
Nudura ICFs in addition provide greater impact resistance and can be engineered to withstand some of mother nature’s worst, like winds up to 250 mph (402 kph) ensuring that the occupants of the home are safe and secure. Nudura’s concrete embedded multi-purpose roof/ truss anchor system provides greater resistance to wind uplift forces than most other conventional systems. Structural reinforced concrete in a Nudura building offers substantially better durability and typically better results in lower life cycle costs compared to wood structures.

EXCELLENT Based on 41 reviews Taryn PassifioneFebruary 24, 2024. Wonderful service! Gary ChernyetskyAugust 16, 2023. My company has been doing business with Castle House for approximately a year. My point of contact is Ben Mitchell. As someone who values and puts an emphasis on customer service in my own business, it was a pleasure to see that Ben is on top of things. I’ve always received a prompt and timely response from Ben. It makes it much more easier for me to communicate with my customers in a timely manner, because I can get technical information, pricing, and most questions answered usually within the hour, or the next day at the latest. Keep up at the good work Ben and the team at Castle House. Adrian GonzalezAugust 2, 2023. I needed 8 windows and was running short on time for one of my projects. No one could help except them. I called and right away Courtney attended to my needs. All my questions were answered and I was able to get the windows done a week before my deadline. They even delivered for a reasonable fee. The price was right and the product was great too. Will definitely be working with them in the future. asimsac aNovember 19, 2022. Best service for my window purchase. The stuff is knowledgeable and prompt. Smooth delivery and effective communication. Very considerate towards my house style, my budget and my own circumstances. Was nervous about wait time, but they organized the delivery the very next day my windows reached their warehouse. They also recommended another company for installation- GR Home Renovation. They were attentive and on schedule. Ended up hiring GR to do other projects in my new home and now that I look back I know that was a wise decision. Tim TingeyNovember 15, 2022. They are great to work with. They have always come through for me. undertheoaks FrenchNovember 11, 2022. Ordered our windows at Castle House Distributors and they came in as planned. Friendly knowledgeable staff helped us not only pick the right windows but their warehouse crew took the time to help me load them up correctly. Highly recommended company, I'll be ordering all my windows from them in the future. Ben MitchellNovember 5, 2022. Jon Childs and his team are the best. Would definitely recommend buying your windows from them! Brett.Steph WOctober 31, 2022. Ben worked with us on a unique project with 2 different window manufacturers. Castle House was a real joy to work with and the results exceeded our expectations!
