Mortise & Tenon with hardwood peg

Joinery of wood used for centuries by woodworkers because of their combination of superior strength and simplicity. They are typically used when one piece of stock is joining to the other at 90-degrees, but may be used at a slightly lesser angle.  Mortise (receiving hole) and tenon (pin insert) joinery results in the joint being strongest when the two pieces of stock are at right angles to one another.

OSB - Oriented Strand Board

Glue impregnated wooden particle board used on the exterior and interior of Structural Insulated Panels (SIPs), or in the place of plywood as construction material. OSB is made from a completely renewable resource -- small-diameter, fast-growing trees.

R-Value

A numerical rating, regulated by the Federal Trade Commission, that represents the resistance of a material to heat flow.  The higher the R-value, the better the product will resist heat flow.   The higher the R-Value, the less heat loss, the better  insulation properties, and the lower the utility bills.

PE Review - Professional Engineer Review

Technical review by a licensed engineer to validate that the home design meets the requirements of the state, county, and city (if applicable) where the home is being built.  Your Davis Frame Company representatives, Doug & Leanne, will support you in having your design reviewed by a State-qualified PE.

Renewable Energy

Heating and electrical energy provided by solar, wind, or geothermal sources, rather than the traditional electricity company.  If a home relies totally on renewable energy as its energy supply, it is referred to as ‘off-grid.’

SIPs – Structural Insulated Panels, or Stress Skin Panels

Composite wall and roof panels that consist of an insulating foam core sheathed on both sides with a structural barrier of OSB.  SIPs require no studs or braces, and therefore eliminate breaks in the insulative action. The end result is a more comfortable, energy efficient structure that performs up to spec in real-world conditions with R-Values up to R-50.

SIPs provide sufficient structural strength to allow the installation of interior drywall, or board, and exterior siding, stucco, rock and brick finishes.SIPs range in R-Value up to R-50, which surpasses conventional construction by >50% to qualify for federal and state tax credits.

Timber Frame

The skeletal structure of a building that is made of hand-crafted timber posts and beams joined together using mortise and tenon joinery and then fastened with hardwood pegs.  The weight of the building transfers through the vertical timbers to the foundation which eliminates settling.  During construction, timber frame walls are assembled on the deck and raised into place.
