Kolbe & Kolbe Aluminum
Clad Windows
There are two types of aluminum cladding
available: roll-formed and extruded.
-Roll-formed
-Extruded
Roll-formed aluminum cladding is a heavy-gauge,
5052 alloy aluminum cladding that is roll-formed to fit
tightly to the exterior wood surface. This maintains the
beautiful profile of wood windows while taking advantage
of the insulating properties of solid wood. The clad corners
are overlapped and sealed for moisture resistance.
Roll-formed aluminum cladding is used as
standard on Kolbe Heritage Select Series windows. It is
an option on Kolbe Heritage Series windows. For Kolbe
Heritage and Heritage Select Series windows, the aluminum
cladding is coated with a polyester film, then baked continuously
to cure and harden. This helps the finish resist marring
and fading, while increasing weatherability of the product.
Roll-formed aluminum cladding is also used
as standard on the sash of Kolbe Ultra Series windows
and doors and is optional on the sash of Kolbe Magnum
Series windows. For Kolbe Ultra and Kolbe Magnum Series
products, the aluminum cladding is covered with a 70%
fluoropolymer finish. This durable coating will keep the
colors vibrant.
Extruded aluminum cladding is used as standard
on the frames of Kolbe Ultra Series windows and doors
and optionally on the frames of Kolbe Magnum Series windows.
It is also used as standard on both the frames and sash
of Kolbe Heritage Select and Kolbe Heritage Series clad
radius windows.
The extruded frames employ a 6063 aluminum
alloy, with walls that are a nominal .050" thick and over.
These windows and doors will withstand environmental extremes
and the rigors of construction. Frame corners are mitered
45° or profile-cut, then internal corner and end keys
are screwed (not crimped) into the joints and internally
sealed with silicone. This makes for exceptionally sturdy
construction, with quality from the inside out. Frame
extrusions are press-fit onto the wood frame, for a superior
union.
Kolbe Ultra Series and Kolbe Magnum Series
clad window frames are finished on the exterior with a
70% fluoropolymer coating which meets the performance
requirements of AAMA 2605-98 specifications. This means
that abrasion resistance is doubled, as compared to coatings
meeting AAMA 2604-98 specifications (similar to previous
AAMA 605.2-92 specifications). Corrosion due to humidity
and salt spray are resisted up to 33% longer. Erosion
and chalking are resisted twice as long - meeting the
10-year weathering performance requirements of AAMA 2605-98.
The same 70% fluoropolymer coating is used
on the roll-formed aluminum clad sash of Kolbe Ultra Series
and Kolbe Magnum Series clad windows. The 70% fluoropolymer
coating will keep these colors vibrant, with color and
gloss retention lasting twice as long as products meeting
lesser AAMA 2604-98 performance specifications. And, design
flexibility is not sacrificed, as custom colors are available
with the same 70% fluoropolymer coating. This proves a
commitment to providing the very best.
Additionally, extruded aluminum accessories
are available for Kolbe Ultra & Kolbe Magnum Series windows,
including 1-15/16" profiled brickmould, 3-1/2" profiled
casing, 3-1/2" flat casing, mull covers, frame expander
covers, two styles of expander trim receivers, mullion
expanders, traditional sill nosing, projected sill nosing,
sill drip edges, and radius nailing fin drip caps.
