Pemko 273FG Series Thermal Barrier Threshold with Frost Guard - 6-1/8"; Width

Professional Thermal Barrier Door Threshold Solution

The Pemko 273FG Series Thermal Barrier Threshold delivers superior energy efficiency with its innovative frost guard design and rigid polypropylene thermal break technology. This 6-1/8"; width threshold features a 3"; half saddle portion on one side with configurable options for the adjacent side, including 1-5/8"; w x 1/2"; h bumper seals with multiple insert choices. Available in aluminum and brass base materials with lengths from 24"; to 185"; maximum, this threshold significantly reduces heat and cold transfer while maintaining ADA accessibility when properly installed.

Professional Features & Benefits

  • Thermal Break Technology: Rigid polypropylene key between extrusions provides effective thermal barrier, minimizing transfer of hot and cold temperatures for improved energy efficiency.
  • Frost Guard Protection: Integrated frost guard design offers enhanced weather protection and thermal performance in demanding climate conditions.
  • Versatile Configuration Options: 3"; half saddle design with choice of additional half saddle widths or 1-5/8"; w x 1/2"; h bumper seal with Pile Brush (P), PemkoPrene (PK), Eco-V (V), or ThermoSeal (T) insert options.
  • Flexible Length Options: Available in lengths from 24"; minimum to 185"; maximum to accommodate various door opening requirements.
  • Premium Material Construction: Available in aluminum and brass base materials for durability and aesthetic compatibility with existing hardware.
  • ADA Compliance Ready: Can achieve ADA accessibility when butted to a 1/4"; offset for barrier-free transitions.
  • Custom Configuration Capability: Compatible with other half saddles to create custom size and configuration saddles for specialized applications.
  • Standard Fastening System: Includes wood screw standard (#10 x 1.5";) with other fastener options available for various substrate requirements.

Pemko 273X3AFG 72 – Frequently Asked Questions

1) Will the Pemko 273FG threshold work on an exterior door where cold is coming through the sill?
That is what the 273FG is built for. It runs a rigid polypropylene key between the two aluminum extrusions, so the outboard half and the inboard half are not in metal-to-metal contact and heat and cold do not conduct straight through the sill. The frost guard design adds weather protection at the same joint. On a heated commercial opening with a cold exterior slab, that thermal break is the difference between this and a plain saddle threshold, which conducts freely and frosts or sweats on the interior edge.
2) How wide is the Pemko 273FG threshold and how does that width break down across the opening?
Overall width is 6-1/8 inches. One side is a 3 inch half saddle; the adjacent side is configurable, either another half saddle width or a 1-5/8 inch wide by 1/2 inch high bumper seal. That matters when you are laying it out against the door stop: you need 6-1/8 inches of clear sill from edge to edge, and you have to decide which side of the door the bumper seal lands on before you order.
3) Is the Pemko 273FG threshold ADA compliant for a barrier-free entrance?
The 273FG can meet ADA accessibility when it is butted to a 1/4 inch offset. That is an installation condition, not a property of the extrusion sitting on a shelf, so the sill has to be prepped to give you that offset. If your slab drops off or steps at the sill, you deal with that before the threshold goes down, or you will not get the transition ADA requires.
4) What lengths does the Pemko 273FG come in, and can I get it for a double door or an oversized opening?
Stock lengths are 36, 42, and 72 inches. The series itself runs from a 24 inch minimum to a 185 inch maximum, so wide pairs and oversized openings are covered within that range. A standard 3 foot single door takes the 36 inch; a pair of 3 foot leaves takes the 72 inch across both. Cut down from the next size up if your frame is between sizes, since aluminum extrusion cuts clean.
5) What seal inserts can I get in the 273FG bumper seal, and which one should I pick?
Four inserts run in the 1-5/8 by 1/2 inch bumper: Pile Brush (P), PemkoPrene (PK), Eco-V (V), and ThermoSeal (T). Pile brush sweeps debris and tolerates a rougher sill; PemkoPrene and ThermoSeal are solid elastomer profiles that close tighter against the door bottom for air and weather; Eco-V is the sustainable-material option distributors get asked for on green-spec jobs. The insert code is part of what you specify on the order, so decide it with the length and finish.
6) What finishes does the Pemko 273FG thermal barrier threshold come in?
Three: mill finish aluminum, dark bronze anodized aluminum, and black suede powder coat. All three are offered in 36, 42, and 72 inch lengths. Mill is the plain silver that disappears against aluminum storefront; dark bronze anodized matches bronze frames and bronze door hardware; black suede powder coat is the flat black that goes with black storefront and black exit device trim. If you are standardizing a building, pick the one that matches the frames you already have and carry it across every opening.
7) What fasteners come with the Pemko 273FG threshold, and will they work in a concrete sill?
Wood screws are the standard supply, #10 x 1-1/2 inch. Those are right for a wood sub-sill and wrong for concrete. Pemko offers other fastener options for different substrates, so on a poured or masonry sill you specify the alternate fastener with the order rather than field-improvising. Contractors setting these on concrete typically want a machine screw and anchor arrangement, and it needs to be called out up front.
8) Should I use a thermal barrier threshold like the 273FG or a plain saddle threshold?
It comes down to whether the opening separates conditioned space from outside. A plain saddle is one solid piece of aluminum, cheaper and fine on an interior or vestibule opening where both sides are the same temperature. The 273FG splits the saddle into two halves joined by a rigid polypropylene key so the metal path is interrupted, which is what you want on an exterior entrance in a cold climate where a solid saddle would conduct, frost, and drive energy loss. On an interior door, the thermal break buys you nothing.
9) Can I combine the Pemko 273FG with other half saddles to build a custom threshold width?
Yes. The 3 inch half saddle on the 273FG is compatible with other Pemko half saddles, which lets you assemble a custom size and configuration saddle when the sill condition does not match a stock profile. That is the route for wide sills, odd frame depths, or matching an existing threshold footprint you are replacing without recutting the slab.
10) I manage a portfolio of buildings, will the 273FG match the thresholds already on my other entrances?
Match on two things: the overall width and the finish. The 273FG lays in at 6-1/8 inches overall, so if the existing thresholds are a different width, the fastener holes and the sill footprint will not line up and the transition at the door stop changes. Finish-wise, mill, dark bronze anodized, and black suede powder coat cover most commercial frame colors. Measure one existing threshold edge to edge before you standardize the fleet on this one.
11) Is the Pemko 273FG available in brass as well as aluminum?
Aluminum and brass are both offered as base materials in the 273FG series. Brass is the choice where the threshold has to match brass or bronze entrance hardware on a storefront or a historic building; aluminum is the working default on commercial openings. Note the stock finishes carried are the aluminum ones, mill, dark bronze anodized, and black suede powder coat.
