The METROLITE greenhouse is a prefabricated, 
factory painted and glazed, large-light, sash-type 
structure of conventional straight-eave design. The 
structure consists mainly of wood sash and framing 
members, all milled from clear all-heart sap-free Cali- 
fornia redwood (Sequoia Sempervirens), a species uni- 
versally known for its long life properties. 
Foundation work is reduced to a minimum. All that 
is necessary is a shallow foundation of 8" wide poured 
concrete or 8" concrete blocks. A substantial wood 
sill is provided with the greenhouse, being anchored 
to the foundation by means of anchor bolts. 
The sidewall panels, 134"' thick, are for 2' 4" wide 
unit spacing, the panels having one light of 24" x 32" 
glass over a solid panel of waterproof plywood or 
other suitable material. The sidewall panels start at 
grade. Therefore, there are no masonry or wooden 
base walls to build above grade. 
The roof panels, also 134"' thick, are for 2' 4" wide 
unit spacing, and are arranged to receive 24" x 32" 
glass. The roof ventilator sash are made in 4' 8" spac- 
ing units, arranged to receive two lights of glass, to 
match the roof panel spacing. They are arranged into 
a continuous run as is shown on the drawings. 
Metropolitan's METROLITE prefabricating methods 
include factory drilling of all bolt holes in the sash 
panels for accuracy and greatest economy in field 
erection. Screw holes are not factory drilled as they 
may be done in the field with a push drill with equal 
economy and for greater accuracy. Long run members, 
such as sills, eaves, ridge and ridge cap, are factory 
splice cut and end cut for quick accurate field 
assembly. 
GENERAL 
DETAIL 
SPE C ie 
Galvanized steel battens are provided to cover all 
roof and side panel joints to assure a tight, weather- 
proof job, to keep out the rain and to reduce heat 
losses. 
A continuous wood member is provided along both 
eave lines. This member is designed to receive the 
lower rails of the roof panels, also the top rails of the 
side panels. Eave brackets are provided to tie side 
and roof panels securely together. 
A wood ridge and ridge cap member is provided 
at the peak of the structure. Ridge brackets are used 
to tie roof panels and ridge securely together. Steel 
crosstie rods are provided at frequent intervals for 
added stability. 
Standard glass gable ends consist of two main 
gable panels, 134" thick (left hand and right hand), 
one door (or blank panel if door is omitted) and one 
panel above. 
Standard greenhouse ventilating apparatus is in- 
cluded as standard equipment with the METROLITE. 
METROLITE leanto models embody the same gen- 
eral features enumerated above PLUS the materials 
for the roof deck which is shown on the leanto drawing. 
The doors are factory mortised to receive the 
locks and hinges. Mortising for the door lock strike 
plate is done by the purchaser for greatest accuracy 
in fitting the door. The appropriate gable sash panels 
are mortised to receive the door hinges. The steel 
crosstie rods, also all lugs and construction fittings, are 
completely shop fabricated, ready for installation.
