I am in the planning phase of building a home in the NJ-NY area, Climate zone 5. As I investigate my options; SIPS, double wall stick 2×4 wood, 2×6 wood, ICFs, CMU, Larsen trusses, etc.. and the myriad of permutations to insulate each one (spray foam, cellulose, hybrid batt & flash, exterior rigid foam/iso panels, etc&#;.) I came across STEEL. My goal is as high R-value as I can get within reason $$, with hope of upwards of R-30 final values. That said, I need some objective input.

Steel seems like a really good option. Almost unheard in my area, despite being upwards of 60% recycled, lasts forever (relatively speaking) super strong, straight, minimal waste, not affected by termites/pests or mold, equal or close to wood in cost (depending who you ask). I know it has very high thermal conductivity. However there are configurations that can abate this significantly (braced walls with double layer of external 2&#; poly-iso taped & staggered seams as sheathing, +/- flash SPF to give the wall more rigidity tieing it all together). Why isn&#;t it more popular? Am I missing something? Thank you kindly for any thoughful input.

Steel framing was originally just used for commercial buildings. However, it has grown increasingly popular for residential use as well. Steel and wood have distinct pros and cons, so it is best to research before deciding which is best for your home. This guide provides an overview of these materials so you can make an informed decision when framing your home.
Steel framing is an excellent option for large builds, primarily because of its strength. Let&#;s look at some of its benefits below.
Steel offers much higher degradation resistance than wood. If there is a water leak, the steel frame will not rot. Steel-reinforced floors will also not warp or bend over time.
Pests cannot penetrate steel, meaning you can save on pest control expenses over time. Steel is even non-combustible, so it structurally withstands fires.
Steel better withstands natural disasters like earthquakes or hurricanes versus wood framing &#; insurance companies may even offer lower insurance rates for steel homes in high-risk regions.
Properly maintained steel frames can endure for generations without needing replacement. It also can support more weight than wood, making it a good option for home designs with heavy roofs or concrete floors.
Steel roof design has some constraints. However, it does offer greater flexibility when used in other design aspects.
For example, steel helps facilitate open floorplans. This is because fewer structural walls and beams are needed because of their innate strength. Steel also readily enables taller ceiling heights, which is impossible with wood frames.
No building material excels in all situations. It&#;s important to know steel&#;s downsides before choosing it as your home framing material.

Remember that adding a wooden roof on top of a steel frame is not as efficient as using a single framing type. Opting for two types of framing could violate your local building codes, too.

Steel is a natural conductor, so it&#;s difficult to install insulation around it. As a result, steel-frame homes may have higher energy bills due to heat or cooling loss, especially in cold climates.
I recommend doing your research ahead of time when choosing a steel frame. Thorough insulation is essential if you are selecting a steel frame.
Wood does not have the risk of rusting. However, it is vulnerable to mold, rot, cracking, warping, and pests over time.
I recommend immediately managing any moisture issues within a steel frame because rust can severely damage the structural integrity of your home.
When deciding between a wood and a steel frame, it is best to weigh both up-front and maintenance costs.
Steel is heavier than wood, so it requires more labor and costs an average of $1.50 per foot to install. Wood prices vary widely, from $1 to $5 a foot, depending on the availability of the timber. Metal frames cost between $2 to $4 a foot.
Factoring in lifetime maintenance costs is essential when deciding between steel and wood framing.

A steel frame&#;s longevity, strength, insurance savings, and damage resistance make it ideal for most homeowners planning new builds or full remodels. Properly insulating steel allows it to outperform wood over decades of home ownership and reduce ongoing maintenance costs. For this reason, I recommend steel framing despite its higher initial cost.
However, if your dream home style requires intricate rooflines that are impossible to create with steel, wood may be your ideal framing material. Speaking with a professional in your area is always a good idea to determine whether wood or steel is best for your needs.
Yes. Steel frames require more insulation as metal frames lose heat more easily than wood frames.
Yes. In some areas, buyers may prefer steel frames due to environmental concerns as well as the material&#;s durability and lower ownership costs. However, a poorly maintained wood or steel frame will depreciate your home&#;s value significantly.
Yes, steel&#;s incredible longevity and recyclability help it earn LEED and other sustainability certifications. Many eco-conscious builds use steel framing.
When kept dry, steel framing lasts over 100 years easily without reinforcement. For best results, perform proper maintenance and repairs on your home to extend its longevity.
