Build Better ICF Homes
Need To Know Facts
Whether you’re building a home that’s large or small, or living in the cooler North or warmer South, when you build a Logix ICF home, you’ll get a stronger, more resilient and more energy-efficient home that will significantly reduce your consumption of natural resources as well as your personal contribution to climate change, while still surrounding your family with unsurpassed comfort and safety.
Virtually any home design can be built with Logix ICF. Most full-height XtraComfort Logix ICF homes are built with our 6.25" or 8" concrete core thickness. Larger homes and heavier loading may require wider concrete cores.
Logix offers engineering tables and the online One Minute Engineer. Both resources comply with prevailing and accepted concrete design standards and conventions. Logix perscriptive engineering covers a wide range of typical residential applications and thus for many XtraComfort Logix ICF homes additional site specific engineering is not required to obtain a building permit.
When you built with Logix Pro, the finished walls in your XtraComfort Logix ICF home will be have an effective R-value of R25. Higher R-value levels an be achieved by upgrading to Logix Platinum Series (R28) or using the Logix D-Rv Panell (up to R37).
Your home's effective thermal performance will be enhanced by the 5 day thermal lag provided by the high-mass concrete core in the Logix exterior walls.
And finally, due to the monolithic nature of Logix construction, your home will be inherently air-tight. In fact, 9 of the most common 19 air-leakage trouble spots shown below are inherently solved by regular Logix construction. And the remaining 10 air-leakage trouble spots are addressed by incremental construction techniques listed in the High Performance Homes application page.
To learn how all these elements work together to create truly superior energy efficiency and significant energy savings - read "The Logix ICF Effect" whitepaper.
"So How Much Does An XtraComfort Logix ICF Home Cost Compared To A Traditionally Built Home?"
Every home, designer, builder and homeowner are different - and there are so many variables in play that make it difficult to arrive an general rule of thumb to accurately answer that question. But here is an example that illustrates the general economics of Logix, given typical lumber prices and prevailing interest rates:
Below grade, assuming you are planning to finish your basement, the cost of Logix construction should be similar to conventional. Above grade, Logix ICF construction can cost in the range of $5 - $8 more per square foot of above grade wall area than an ordinary 2x6 stick-framed wall.
Let's assume a bungalow with 2,000 sq ft of living space and 1,800 sq ft of above grade walls.
$150/sq ft - Budget price to build the home conventionally
$300,000 - Budget price for conventional build (assume $150 sq ft x 2000 sq ft of floor area)
$12,600 - Additional cost to build above grade walls with Logix (assume $7/sq ft premium x 1800 sq feet of above grade walls )
4.2% - Cost premium to build with Logix (($312,600 -$300,000)/$300,000)
$59.00/mth - Additional monthly payment to finance $12,600
So, in this case, if your total heating, cooling, insurance and annual maintenance savings are more than $59.00/month, then building an XtraComfort Logix ICF home will actually be LESS EXPENSIVE and cash flow positive, compared to building a lower quality, lower value stick-framed home.
It's important to note that the cost of soft wood lumber is far more volatile than ICF pricing and when the cost of softwood lumber spikes, as it has for instance in the spring of 2018, the cost of regular wood-frame walls will actually approach the cost of high-performance ICF walls.
More food for thought - in some coastal areas, some builders now offering new homes built with Logix ICF at no extra cost versus the same home built with basic masonry walls, which is a customary construction method in those regions. In this cases, all your monthly savings go right into your pocket.
This 3000 sq ft home (with a 41 ft high back wall) built on a virtual cliff is a remarkable architectural and engineering achievement. Plus, what a view!
This construction of this beautiful home was featured in the 13-episode TV series "House Of Bryan 3" which is the highest-rated TV series EVER on HGTV Canada.
This beautiful multi-generational home provides a level of comfort, cleanliness, energy efficiency and quiet that most people are not aware is attainable.
What people say about building with Logix.
Sheppard Square Homes for the Louisville Metro Housing Authority is a HOPE VI subsidized housing development in which we served as one of the Architect’s of record on. The homes we designed are built using Logix ICF for the walls, as well as ICF for the roofs. These homes should operate with about 25% the energy costs of similar homes in the same development constructed using traditional wood framing. The homes cost about the same as the wood structures, and are similarly finished so they fit in the well planned community.Jill Smith

My new Logix home is close to 2X the size of my previous 1500 sq ft home built with concrete block back in the 70's - and my energy bills are about 35% lower. In addition to the energy benefits, I was pleasantly surprised how quiet the house it.Zander Strong
