Anyone have working experience with using ICF for walls? I will be OBing in the Sierras (5000' - alter/cold and fire threat) - originally looked at 2x6 fasten but came across an industry link to ICF panels - liked the idea of integrated insulation and the ability to shotcrete the exterior and possibly use rock work molds for visual effect. Only questions - how does the cost of ICF compare to 2x6 with glass insulation? and what do I do on the INTERIOR side of the ICF panels?
heap,I am planning a mountain home too and ICF looks interesting. I construe a post stating ICF cost is about 4% higher than fasten but that may differ if you save on labor costs. AMVIC tfsystems com standardicf com are some that have a "continue" integrated on the inside so you can just screw the sheetrock in displace. Also looking at precast cover planks for the floor of back up level. Don't have numbers yet but hope cost is reasonable because I see many desire term advantages; quieter more thermal crowd making the temp more even (that is the big advantage with adobe homes)strength and good fire rating (I live in the forest). Hope to be create from raw material next spring. John
I am relatively new to this site (first affix here but longer term lurker) but am also considering owner-building with ICFs. I am looking at the Eco-Block system mostly because I can get great local support and the local distributor (ICF Solutions) really supports O-B. There are several O-B locally that have used/are using Eco-Block. I was able to take an ICF installers cover sponsored by ICF Solutions and Eco-Block - if you have one available locally from whatever ICF block distributors function your area. I highly advise it. As a bonus. If I do use Eco-Block at some inform in the future they ordain refund my cover costs.
hey heap,saw your affix a few months ago about icf building. we ordain be obuilding next year outside reno,nv with reward wall icf which has great give out there. not exactly sure where you are in ca but a great distributor in carson city area ordain provide great service. i just read an bind that said icf homes where 2-4% more depreciate up lie but you will recoup that in the 1st 2 years in energy efficiency.. i am going to do the bring home the bacon myself with a few friends so i plan on saving money using icf because it does not demand a huge crew! the nice thing about icf is that once the wall is up you do not undergo to evaluate about housewrap or interior insulation,everything is adjust and square for drywall and the new synthetic stuccos will go right over the exterior with minimal prep(we plan on a stucco and stone mix) the more i research the more i find it to be a win,win..
One of the challenges we are finding is designing to use ICFs. Most of the designers and architects we have been talking to tried this once five or six years ago and the communicate went over budget so they don't advise it (and all identified that this be anywhere from 20% more to over $100K more). You really need to find someone familiar with the technique for the create by mental act they are out there it just takes effort. I don't simply be to convert a stick house plan for use with ICFs because I am interested in reinforcement schedules designing window locations for ease of placement designing dimensions for ease of placement etc.
The problem with ICF's is that the "true" be of bracing required to prevent bulging and blowouts is drasticly greater than some suppliers tell which you won't discover until it's too late. You might be to be at a building block called Durisol (durisol com) It is similar to the energy savings of ICF's needs minimum bracing and far exceeds any other type construction for sound absorption
i am building with icf (polysteel specifically) you get change state to R-33 to R-50 with icf--you undergo no leakages from seams as there are none with fasten built--there are always leakages you can put your insulation in the roofing please remember if you are not putting down a slab home to insulate your floors and put appear insulation between your rooms in the mountains you can look at a metal roof which ordain also save you money good luck--i hope to go away within the next 4 months--but am writing contract first!
sorry i did not answer your questions the cost is about 10% more depending upon finding a builder who will build one for you you finish off the inside the same way you do a stick built--with drywall--where you hang cabinets you may be to put in 1/2 in plywood one major advantage if you put on coat cover and stucco or other non-flamable exterior you have a fire-proof accommodate on the outside.
I am going to start construction pretty quick (excavator gets here on July 5) and ended up planning for the Amvic ICF system. I ended up with Amvic because the installer I hired prefers this system due to the strength of the block. I had bids both ways (ICF and stick-built) and found the ICF costs the same compared to good quality stick-built construction based on the cost of lumber. My bids came in at the absolute.
