wood, aluminum, steel, vinyl, fiberglass - ANS-5 materials used in contemporary windows
Pros: high R-value
Cons: swelling, shrinkage, fungal decay, termite vulnerability, need for periodic staining/painting
- ANS-wood window advantages/disadvantages
Pros: malleable, flexible
Cons: low R-value - ANS-aluminum window advantages/disadvantages
Pros: sleek appearance, great durability, great resistance to lateral loads
Cons: aluminum is more commonly used - ANS-Steel window advantages/disadvantages
Pros: provide excellent R-value
Cons: high coefficient of thermal expansion - ANS-Vinyl & Fiberglass window
advantages/disadvantages
fixed, single hung, double hung, casement, awning, hopper, pivoting, horizontal sliding -
ANS-Diff. kinds of windows
metal doors, specifically steel doors - ANS-What type of door frame materials are used in fire
related assemblies?
w/ nailing flanges for exterior wood siding, stucco, and EIFS cladding.
w/o nailing flanges for aluminum windows - ANS-methods of window installation include
installed prior to wall finish; knocked down; steel stud wall anchors - ANS-methods for installing
hollow metal door frames
aluminum because anodized/painted finish is virtually permanent - ANS-Most maintenance free
materials for windows are:
mullions installed first, then rails, then glass panes within mullion-rail framework. - ANS-Stick
built glass curtain wall components:
thermal expansion and contraction of mullions are accommodated by expansion joints in
mullions. - ANS-how to deal with expansion/contraction in stick built glass curtain wall?
outside glazed: pressure plate-captured glass or structural silicone sealant-adhered glass
, inside glazed: no pressure plates; more efficient because no need for scaffolding or staging -
ANS-How is glazing installed in a stick-built glass curtain wall?
anchoring wall through mullions. then rails are inserted btwn mullions. then 2 separate areas of
glass at each floor - ANS-constructing a stick built glass curtain wall involves:
framed wall units that are prefabricated, then interlocked to form mullions and rails; greater
degree of quality control resulting from shop fabrication. greater shipper cost tho - ANS-unitized
glass curtain wall components include:
storefront wall is not spaced away from structural frame of building (curtain wall is)
storefront wall's glazing system's performance for both struct. and non struct is weaker than that
of a curtain wall
storefront drainage thru weep holes, curtain wall drainage thru rail support - ANS-diff btwn glass
curtain wall and storefront system
fastened to framing members, after glass panes are in position, temporary pressure plates are
removed and replaced by full-length pressure plates - ANS-how do 'pressure plate captured
glasses' work?
enclose steel sections within the mullions, anchor mullions to independent steel structural frame
- ANS-how is lateral load bearing capacity of a standard glass-aluminum window wall
increased?
water resisting roof consisting of continuous roof membrane over a relatively flat roof surface -
ANS-definition of low-slope roof?
water-shedding roof consisting of small individual roofing units (shingles) that overlap each
other - ANS-definition of steep roof?
three to five plies (layers) of felt with intervening mopping of bitumen (asphalt or coal tar). -
ANS-essential components of built-up roof membrane?
Starts w/ bucket of hot bitumen and a mop, then bitumen is dispensed on roof. Unrolling of felt is
then pressed down with a squeegee. After, flood coat of bitumen is applied and stone aggregate
surfacing, typically applied with shovel for small roofs. - ANS-order of construction for
components of built-up roof membrane?
A dragon wagon consists of a series of propane torch heads mounted on a wheelable cart that
also carries the APP sheet roll; modified bitumen membrane - ANS-What's a dragon wagon?
What type of roofing system is it used in laying?
