This is a concrete question more than a radiant heating question. All concrete applications must be structurally satisfactory. There is no important difference between concrete mixes from the heating standpoint.

ThermaSAVE Building Systems offer tremendous advantages over traditional wood stud construction. Buildings made with ThermaSAVE panels are more energy efficient; more resistant to fire, water, wind, mold, snow loads, and earthquakes; and much faster and easier to construct. All this results in significant savings for builders, owners, and the enviroment.

Some people need a particular species of wood, because they are matching to an existing floor. When matching to an antique floor, it is particularly important that you order flooring that will be milled from material that was cut at the same time as your existing floor. This means making sure that your new flooring is coming from original growth and not new growth trees. We also want to make sure that we match the species that you currently have.

This varies depending upon what part of the country you are in. Pressure Treated lumber is usually Hem-Fir in the West and Southern Yellow Pine in the East and South. The framing lumber is also regionally dependent. It can be Douglas-Fir, SPF (Spruce-Pine-Fir), SYP (Southern Yellow Pine) or Hem-Fir. The roof trusses can also be a variety of the same species, but will usually have msr (Machine Stress Rated) lumber for chords.

Woodfold Roll-Up Doors are offered standard in Maple, Birch, Cherry, Mahogany and Oak. We also offer other hardwood species on special request, though due to quality standards, we don't offer softwood species.

All lineal mouldings are stocked in Poplar; some also in Red Oak. Hand-carved woodcarvings are available in Lindenwood, with some also in Maple and Cherry. Custom species are available upon request - see "Our Services" for list of custom species.

We can utilize most any species that is suitable for structural purposes. However, we often use Douglas Fir because it combines beauty and structural strength comparable to many favorite hardwoods without the shrinkage and weight issues.

We build over eighty percent of all Kodiak Log Homes out of Engelmann Spruce, it has a good strength to weight ratio, is a beautiful blonde wood and is native to many dry climates. We also build many log homes out of Douglas Fir (attractive grain colour and superior structural strength) , Yellow Pine (full of character), and Western Red Cedar (attractive color in the grain and a natural resistance to insects and decay) for an up-charge of fifteen to thirty percent.

We work with oak, poplar, maple, and cherry on a regular basis. Other hardwoods are available as limited basis.

We offer the most common hardwood species including maple, mahogany, cherry, walnut and oak. The wood keys are sold by the linear foot, to be cut to size by the customer, or on a special order basis pre-cut to size by Hoffmann. Lead-time for cut-to-order wood keys is usually 4 - 6 weeks. We can manufacture wood keys in species other than the ones listed, please call for details.

If you can supply us with this information, we can help you decide on a starting point for your spine selection. We ask for this much information because, "Anyone you ask can GUESS at what spine you need, but the more information you give US the more EDUCATED that guess can be." The standard string material, B-50 is requires no extra "figuring". A fast flight string requires a jump in spine of 5-7 pounds. The Artificial Sinew string is heavy, thick, and stretches very much.

The heartwood of naturally durable species such as western red cedar, yellow cypress and white cedar will all resist decay to some degree, but it is variable. The amount and type of natural fungi-toxic chemicals deposited in the heartwood determine how durable the wood is. The sapwood of all species is considered non-durable. Heartwood of second growth may be less durable than the best of the old growth but probably less variable.

Simply put, other products do not work effectively. Some over-the-counter trays are not moldable to your teeth and do not hold the gel in the proper position. Many OTC whitening gels are not thick enough to stay in place and will leak out of the tray. Many OTC gels typically have less effective active ingredients or a lower concentration of active ingredients.

Energy consumption is affected by many variables such as system size, elevation, outside temperature and how well the home is insulated. We can determine how much it will cost per continuous hour to operate the system once we know about the variables.

Programmable thermostats can be used, but consider this: Radiant systems are designed to maintain a constant temperature. It can take quite a while to warm a room from a cold start and the system is going to use a lot of energy to heat the room. Digital thermostats are more precise than standard mercury-bulb thermostats and may cause the system to cycle too frequently. Mercury-bulb thermostats are generally the best choice for radiant systems.

Choosing a species of wood involves more than selecting a color to match your décor. Different species of wood flooring will experience color changes at different rates. In general, more-common species such as oak and hickory will experience minimal color change over time, while less-common species, like cherry will show more color change over time. A Heritage representative from would be happy to recommend the type of wood flooring product that best suits your needs.

Radiant Barrier is a material that is a poor re-transmitter of infrared waves (radiant energy). By definition, this re-transmission characteristic (emissivity) must be at or below 10%. The emissivity of Reflectix? products is approximately 3%. Therefore, when a Radiant Barrier is installed in a residential attic, it "blocks" 90% + of the radiant energy that is being radiated by the hot roofing materials.
