timber frame roof & enclosures

C

Compound Roof: Hip roof (outside corner) or valley roof (inside corner) formed where two adjacent roofs join at an angle.

Compound Truss: Truss employing more than one standard configuration, such as a kingpost truss super-imposed on a queenpost truss to support a simple gable roof.

D

Dormer: A space or window of variable shape rising upright from the surface of a roof and having its own roof.  According to its extent and form, a dormer can be termed eyebrow, doghouse, roundhead, shed or running.

Double Rafters: Principal rafters stacked one above the other, usually in a king post truss, intended to share compressive loads.  The upper rafter, terminating at the eaves, supports purlins and maintains the roof plane.  The lower rafter, seated inboard of the end of the tie beam, obtains security against decay.

E

Eaves (singular and plural): The drip edge of a roof, often overhanging the wall.

F

Fascia: Generally, a face board to cover the exposed ends of joists or rafters. 

 

G

Gable Roof: A double sloping roof that forms an A-shape.

Gambrel Roof: A double pitched roof with the lower slope steeper than the upper slope.

Hip Rafter: In a roof frame, the rafter that follows the line of the hip, typically backed to follow the slopes of the adjacent roofs.

Hip Roof: Compound roof occurring where two roof slopes meet over an outside corner.

I

Infill: 1. Insulation placed between studs inside timber framed walls. 2.Studding placed between major posts to support interior and exterior finish.

J

Jetty: Cantilevered overhang of the floor of an upper story.

M

Mud and Stud: Late English framing method using relatively few and light framing members infilled with wattle and daub.

R

Rake: In a gable or gambrel roof, the edge of the roof as seen at the gabel end.

Roof Pitch: Inches of rise per foot of run. For example, a 45-degree roof has twelve inches of rise for each foot of run and is therefore called a "twelve pitch" roof.

S

Shed Roof: A roof sloping in one direction.

Soffit: The underside part of a building such as under a roof overhang.

Stress-Skin Panels: A sandwich of materials, containing two skins, one inside and one outside, and a core of insulation.

V

Valley Roof: A compound roof resulting from two roof slopes meeting over an inside corner.

W

Wattle And Daub: A framework of woven widths covered by layers of daub mixed of clay, lime, and horsehair and cow dung, used to fill openings between studs in early timber frames.
