1Under AAMA 2400, what does Method A specify for the placement of jamb flashings during replacement window installation?

A.Jamb flashings are applied before the window is installed, in weatherboard fashion

B.Jamb flashings are applied after the window is installed in the opening

C.Jamb flashings are not required if the WRB is intact

D.Jamb flashings are installed only on the exterior trim, not the rough opening

Explanation: AAMA 2400 Method A places the jamb (side) flashings AFTER the window is set in the opening. The mounting flange sits against the WRB, then jamb flashings are applied over the flange and continue up onto the WRB.

2What is the primary distinguishing feature of AAMA 2400 Method B compared with Method A?

A.Method B applies jamb flashings before the window is installed in weatherboard fashion

B.Method B uses metal flashings exclusively

C.Method B is for new construction only

D.Method B requires removal of the existing WRB

Explanation: Method B applies the jamb flashings AFTER the sill flashing but BEFORE the window is set, lapped weatherboard (shingle) fashion. Method A reverses the jamb sequence (jambs after window).

3Before performing an AAMA 2400 insert (pocket) replacement, what is the FIRST condition the installer must verify on the existing frame?

A.That the existing frame is structurally sound, square, and free of rot or decay

B.That the existing weights and pulleys are still operational

C.That the existing glass is single-pane

D.That the home was built before 1978

Explanation: AAMA 2400 requires the existing frame to be structurally sound, square within tolerance, and free of rot, decay, or insect damage before an insert replacement is acceptable. If the frame is compromised, a full tear-out (AAMA 2410) approach is required.

4Under AAMA 2400, a Method A insert (pocket) replacement window is most appropriate when:

A.The exterior cladding and existing frame must be removed for access

B.The existing frame is sound and the WRB/flashing system will remain undisturbed

C.The opening will be enlarged for a new size

D.The WRB is compromised and must be replaced

Explanation: Insert (pocket) replacement under Method A is intended for openings where the existing frame is sound and the existing exterior cladding, WRB, and flashings will remain undisturbed. If those systems are compromised, a tear-out approach following AAMA 2410 is appropriate.

5What is the purpose of the weep system on a replacement window installed per AAMA 2400?

A.To allow incidental water that gets past the gaskets to drain to the exterior

B.To equalize interior and exterior air pressure for ventilation

C.To allow condensation to drain to the wall cavity

D.To prevent solar heat gain

Explanation: Weep holes are designed to drain any incidental water that bypasses the exterior gaskets out of the sill chamber to the EXTERIOR. They must never be sealed shut, and they must not be allowed to discharge into the wall cavity.

6When installing an AAMA 2400 insert replacement window, what should be done with the exterior weep holes after the window is set?

A.Seal them with caulk for energy efficiency

B.Leave them open and unobstructed so they can drain freely

C.Fill them with low-expansion foam

D.Cover them with screening on the exterior

Explanation: Weep holes must remain OPEN and unobstructed so they can drain. Sealing or foaming them traps water in the sill chamber and causes premature failure of the unit and the surrounding wall assembly.

7AAMA 2400-21 applies to the installation of windows with a mounting flange in wood-frame construction using what method?

A.Drainage plane methods

B.Exterior barrier methods

C.Face-sealed barrier methods only

D.Pressure-equalized rainscreen methods

Explanation: AAMA 2400-21 is titled 'Standard Practice for Installation of Windows with a Mounting Flange in Wood-Frame Construction Using Exterior Barrier Methods.' It addresses low wind/water exposure and barrier-style wall assemblies.

8During an AAMA 2400 Method B installation, when is the sill flashing applied relative to the jamb flashings?

A.After the jamb flashings, so the jambs lap over the sill

B.Before the jamb flashings, so the jambs lap over the sill in weatherboard fashion

C.At the same time as the head flashing only

D.Sill flashing is not required if a sill pan is present

Explanation: Under Method B, sill flashing is applied FIRST, then jamb flashings lap over the upturned legs of the sill flashing in shingle (weatherboard) fashion so water sheds outward and downward.

9What is the recommended exterior-perimeter sealant detail when installing an AAMA 2400 replacement window with a brickmould or nail fin?

A.Continuous bead on the exterior perimeter except for a left-open section at the bottom for drainage

B.Continuous unbroken bead around all four sides including the sill

C.Bead applied only on the sides and head, leaving the entire sill open

D.No sealant — gaskets alone handle weatherproofing

Explanation: AAMA practices call for a continuous perimeter sealant bead at the head and jambs, with the sill area left open (or with intermittent gaps/weeps) so any water that bypasses the seal can drain rather than being trapped.

10Which sealant type is generally NOT recommended for the exterior perimeter seal of a replacement window?

A.Polyurethane

B.Silicone (compatible)

C.Pure-acrylic latex non-paintable interior caulk

D.Modified polymer/STP designed for fenestration

Explanation: Interior, low-grade latex caulk lacks the elasticity, UV resistance, and adhesion to the dissimilar substrates (vinyl, brick, stucco) typical of an exterior fenestration joint. Polyurethane, fenestration-grade silicone, and STP/MS polymers are appropriate.

FGIA InstallationMasters Study Tips from Top Performers

1Memorize the flashing sequence: sill pan → window → jambs → head → WRB integration; each upper layer overlaps the lower (shingle-lap) so water sheds outward

2Method A: jambs installed AFTER the window; Method B: jambs installed BEFORE the window in weatherboard fashion — both are AAMA 2400/2410 compliant

3Sill pan flashing bottom edge is NOT fastened/adhered so the WRB can later slip up under it (weatherboard lap)

4Flashing tape widths: at least 4 inches at jambs, 6 inches or wider at the sill pan (ASTM E2112)

5Shim spacing: max 16 inches on the sill, max 24 inches on the sides; quarter-point placement; do not shim the head

6Expansion gap: ¼ inch between frame and cladding; backer rod + sealant; use LOW-expansion foam only

7DP rating = static psf the window must resist; water test is at 15% of DP (≥2.86 psf minimum)

8Field tests: ASTM E1105 = water; ASTM E783 = air (field); ASTM E283 = air (lab); AAMA 502 wraps both for installed fenestration

9Energy Star v7.0: Northern U ≤ 0.22 (with SHGC ≥ 0.17), South-Central U ≤ 0.28 SHGC ≤ 0.23, Southern U ≤ 0.32 SHGC ≤ 0.23

10Operator types and their weeps: DH/sliders/casements all have weep holes that must remain unobstructed — never seal the exterior weeps shut

Frequently Asked Questions

What is the difference between AAMA Method A and Method B flashing?

Method A and Method B differ only in the placement and sealing of the jamb (side) flashings. In Method A, the jamb flashings are applied AFTER the window is installed within the opening. In Method B, jamb flashings are applied in weatherboard (shingle) fashion AFTER the sill flashing and BEFORE the window is installed. Both produce a water-shedding system when executed correctly.

What is the correct flashing sequence for AAMA 2410 new construction?

Apply flashings in shingle-lap sequence so water sheds outward: (1) install sill pan flashing first (bottom of rough opening), with the bottom edge NOT adhered so the WRB can later slip up underneath; (2) install the window with the mounting flange sealed at the head and jambs (sill bead per manufacturer); (3) apply jamb flashings over the flange; (4) apply head flashing OVER the jamb flashings; (5) integrate the WRB so each upper layer overlaps the layer below.

What does ASTM E2112 cover?

ASTM E2112 is the Standard Practice for Installation of Exterior Windows, Doors, and Skylights. It covers fenestration installation in new and existing residential and light-commercial construction, with a strong focus on water management — sill pan flashing, jamb and head flashings, drainage planes, WRB integration, and the shingle-lap principle that ensures water always flows down and out, never behind the flashing.

What is a Design Pressure (DP) rating?

DP is the pounds-per-square-foot static air pressure a window must withstand without failing tests for structural integrity, water penetration (at 15% of DP, typically ≥2.86 psf min), and air infiltration. Common residential DP ratings range from DP-15 to DP-50; higher DP windows are required in high-wind zones and hurricane-prone regions. DP is measured per AAMA/WDMA/CSA 101/I.S.2/A440 (NAFS).

What is the difference between ASTM E1105 and ASTM E283/E783?

ASTM E1105 is the FIELD test for water penetration of installed windows, doors, and curtain walls under uniform or cyclic static air-pressure difference (simulates wind-driven rain). ASTM E283 is the LAB air-leakage test, and ASTM E783 is the FIELD air-leakage test. AAMA 502 references E1105 and E783 to validate the installation of newly installed fenestration.

How should shims be placed for a vinyl replacement window?

Shim at the quarter points of the sill (not under operable sash meeting rails alone) so the unit is supported, and at the sides 4–6 inches from each corner and at lock keepers. Maximum spacing is about 16 inches on the sill and 24 inches on the sides. Shims are normally NOT used at the head. Fasten THROUGH the shims so the frame does not distort, and use low-expansion window/door foam — never high-expansion foam.

What expansion gap should be left between the window frame and exterior cladding?

Leave approximately ¼-inch gap between the window frame and adjacent exterior cladding (siding, brick, stucco, or stone) on all sides to allow thermal movement. Fill with the correctly sized backer rod and seal with a high-grade exterior sealant compatible with both substrates. The exception is vinyl J-channel, which is designed to receive the cladding directly.
