Solarium Surface Calculation

Square Eaves -or- Double Gable:

R= Roof
H= Height @ Attachment Point
W= Width from Attachment Point
L= Length @ Face
F= Face Height

To Calculate Surface Square Footage:

1. Gable End (G.E.):
H x W = 8' x 10' = 80 sq.ft. x 2 G.E. = 160 sq.ft.

2. Roof:
R x L = 9' x L
( Note: Due to off cut on Acrylic sheet, we use 9' instead of 8' 7 ½" )

3. Face:
F x L = (7' x L) - (Knee wall area)
( Note: Due to off cut on Acrylic sheet, we use 7' instead of 6' 5". Also the example employs use of a 24" height [2' x L = sq.ft.], Knee Wall, this usually would be calculated as a separate rate depending on the methods and materials therein. )

Example: ( From Above Plan )

Assume L = 20 ft.

Therefore:           Gable End:   H x W = 8' x 10' = 80 sq.ft. x 2 G.E. = 160 sq.ft.
                                                                      ( Less Knee Wall @ ( 2' x 4') + ( 2' x 10' ) = 28 sq.ft.
                             Roof:            R x L    = 9' x 20' = 180 sq.ft.
                             Face:           F x L    = 7' x 20' = 140 sq.ft. ( Less Knee Wall @ 40 sq.ft. )
                             Knee Wall:    [(2' x 10')+(2'x4')] + (2'0" x 20') = 28 sq.ft. + 40 sq.ft. = 68 sq.ft.

Hence: TOTAL Glazed Area: 160 + 180 + (140 - 68) = 412 sq.ft.

If you are pricing the above example:
(Note: Prices shown are examples only.)

COST:

412 sq.ft. x $18.00 U.S./ sq.ft. = $ 7,416 U.S. + [ Freight: (FOB Victoria, B.C.) ]

RETAIL:

412 sq.ft. x $ 30 - 35 / sq.ft. = $ 12,360 U.S. - to - $ 14,420.00

( Note: Remember that you will be adding the Knee wall and any other preparation work to this total. ) Volume ordering will decrease your material cost per sq.ft. and shipment cost per unit.

Curved Eaves -or- Double Gable:

R= Roof
H= Height @ Attachment Point
W= Width from Attachment Point
L= Length @ Face
F= Face Height

Exactly the same calculations as above are used in Curved Roof / Face Solariums.
