Oak Homes Frequently Asked Questions
Why should I use a "machined" rather than a "peeled" log?
1) By machining the logs, we are able to obtain a uniform surface for the logs as well as uniform size. This eliminates ledges which can catch water and cause decay.
2) Machining removes the "sapwood" which is the least durable part of the tree. It also eliminates any insects which may be living under the bark of the tree. The remaining "heartwood" is the most durable part of the tree.
3) It makes construction easier, more precise and more air-tight. It is also easier to hang items on the interior of the logs (such as pictures) and attach partition frame walls. Flat walls make light switch and plug notches and window and door trim easier to install and more attractive.
Are log homes energy efficient?
Log homes have been proven many times to be energy efficient. The logs as well as the heavy beams in the home effectively serve as thermal mass storage units. This means that they store the warmth and
then radiates it back into the room when temperatures drop. The joints in a log home are accessible from both the exterior and the interior. This means that you can completely eliminate air leakage in your walls at any time. Standard
construction covers up the source of air infiltration and cannot be repaired after the initial construction phase.
Six inch diameter logs are equivalent to an R19 insulation value. A 7 1/2" diameter log will have approximately an R24 value. As a rule of thumb, a 7 12" diameter log should perform equal to a 2x6 frame wall with fiberglass insulation, which is R21.
Which is better: Oak or Pine?
Oak has several differences from Pine logs.
- It is more durable (naturally, without chemicals).
- It is more resistant to insects.
- It does not season check as severely as Pine
- It is much stronger, and thus header logs and floor beams can span longer lengths.
- In colder climates, pine is never used for exterior trim or siding unless it is primed and painted.
- We believe that the Oak interior wall is much more beautiful because of the color of the wood and the diversity of the grain patterns.
In some ways the two species are the same
- Their insulation values are the same.
- Two people are required to lift most logs.
- Financing and insurance is the same.
Which is better: Oak or Cedar?
Oak and Cedar are both very durable against insects. Only Oak heartwood is used in Gastineau Log Homes, which is as durable and insect resistant as the
cedar available on today's market. Oak has three differences from Cedar:
- It is much stronger. This is especially important considering the spans over some very wide windows, garage doors, sliding doors, etc., as well as the floor beams used in two story homes.
- World renown for its beauty, Oak has a vibrant grain pattern and color that is more appealing for an interior wall.
- Cedar usually will cost more.
What are the advantages of the Therma-Log system over a Half-Log system?
- It is milled to precise dimensions giving the same advantages of milled vs peeled logs: uniform surface, removal of sapwood, the least durable part of the tree, eliminates insects, makes construction easier, more precise and more air-tight
- It has a single tongue and groove for a more air-tight construction.
- It is installed with screws rather than spikes. These are easier to install and with greater precision.
- We have full log corners, for a more authentic look. (Round vertical posts corners are available also.
- The wall system is the same price as our full log wall.
- It is offered in both a round and flat/beveled exterior.
Can a log be replaced in a wall after it is constructed?
Definitely. The exact process varies according to the log's location, but this can be done. This exhibits another advantage to log home construction: because the logs are placed horizontally, the weight of the home and roof is distributed evenly over the length of the wall. In frame construction, one vertical stud is supporting every 16" of wall.
What items will we need to purchase to finish the home?
You will need the foundation, the electrical, plumbing, heating, roof insulation, finish partition wall or ceiling material (if not purchased optionally), bath and kitchen cabinets, appliances, light fixtures, fireplace, carpet, door knobs, roof flashing if required, and labor.
