Cal-Royal INT-001B-17 – Frequently Asked Questions

1) What gap size will the Cal-Royal INT-001 weatherstrip actually seal?
The INT-001 silicone seal starts compressing at a 1/4 inch gap and compresses down to seal gaps as tight as 1/16 inch. So if the clearance between your door and stop falls anywhere in that 1/16 to 1/4 inch window, the strip will make contact and seal. A gap wider than 1/4 inch won't get compression, and you'd want a heavier gasket or an adjustable jamb-mounted stop instead.
2) Can I use the INT-001 weatherstrip on a hollow metal frame, or is it only for wood?
Both. The INT-001 is a press-on adhesive strip suited to wood and hollow metal door frames. Because it mounts with 3M adhesive tape rather than screws or a kerf groove, there's no routing or drilling into the frame, which is why it works across both materials. Clean the stop face before applying so the tape gets full bond.
3) My frame has a kerf groove already. Is the adhesive INT-001 the right choice?
No. The INT-001 is a surface-applied adhesive strip that presses onto the face of the stop. If your frame is kerfed, a kerf-in gasket seats in the groove and holds mechanically without relying on tape. The Pemko Q103W Series kerf-in foam weatherstrip with extended flange, 1-1/4 x 3/16 inch, is the style you want in that case.
4) What is a comparable adhesive-mounted smoke seal to the Cal-Royal INT-001?
The Hager 726S smoke seal weatherstrip uses press-on installation, so like the INT-001 it goes onto the frame stop with adhesive rather than requiring a kerf or screw-applied carrier. The INT-001 differs in its material and range: silicone rubber with 3M adhesive tape, rated for use from -58 degrees F to 450 degrees F, with a seal that begins compressing at 1/4 inch and closes gaps down to 1/16 inch. The Hager 726S is finished in charcoal; the INT-001 is offered in black and white.
5) What lengths and colors does the Cal-Royal INT-001 come in?
Two lengths, 17 inch and 25 inch, each in black or white. Those are short sections rather than full jamb runs, so for a standard opening you'll be piecing lengths together along the head and hinge jambs. Count your total linear footage per opening before ordering.
6) Will this weatherstrip hold up in an unconditioned warehouse or a boiler room?
Rated for use from -58F to 450F, so cold loading docks and hot mechanical rooms are both inside its range. The silicone rubber is also called out as resistant to sunlight, ozone, oxidation, weather and water, and it won't support mildew or fungus, which matters in humid or wash-down spaces.
7) Does the INT-001 seal smoke, or just drafts?
It restricts air, light, smoke and insects around the door opening, and the silicone is non-toxic and self-extinguishing. That makes it a candidate for smoke and draft control on commercial openings as well as straight energy sealing.
8) What else could I use instead of the Cal-Royal INT-001 for door perimeter sealing?
A few directions depending on how the frame is built. The Hager 726S is another press-on smoke seal, in charcoal, if you want the same no-drill install. If you'd rather have an adjustable metal carrier that you can dial in against a door that has settled, the Hager 864S is an 84 inch clear anodized aluminum adjustable jamb weatherstrip with a neoprene insert, and the Hager 862S is a 48 inch neoprene-insert strip for smoke and draft control. For the head of a fire-rated opening, the Pemko 68 is a 40 inch fire-rated door top weatherstrip with a black sponge neoprene insert.
9) Do I need screws or fasteners to install the Cal-Royal INT-001?
No fasteners. The strip ships with 3M adhesive tape already on the back, so installation is clean the stop, peel and press. Nothing else is required to complete the job, and there's no prep to the frame, which is why it's a common pick for retrofitting occupied units without pulling doors.
10) Is a neoprene weatherstrip like the Hager 862S a direct substitute for the Cal-Royal INT-001?
Not a like-for-like swap. The Hager 862S uses a neoprene insert for smoke and draft control and is furnished in a 48 inch length. The Cal-Royal INT-001 is a silicone rubber strip with an intumescent element, self-extinguishing and resistant to sunlight, ozone, oxidation, water, mildew and fungus, applied by 3M adhesive tape to wood or hollow metal frames in 17 inch or 25 inch pieces. The material, the intumescent function, the mounting method and the lengths all differ.
11) Which weatherstrip should I use if I need a full 7 foot jamb run in one piece rather than the Cal-Royal INT-001?
The Hager 864S is an 84 inch adjustable jamb weatherstrip in clear anodized aluminum with a neoprene insert, which covers a full jamb height in a single piece. The Cal-Royal INT-001 is supplied in 17 inch and 25 inch lengths, so longer runs are built up from multiple adhesive pieces.
12) Is the INT-001 meant for commercial openings or residential doors?
Cal-Royal classes the INT-001 as commercial door hardware, and the application list runs to offices, schools, healthcare, retail, warehouses, multi-tenant residential and government buildings. It will work fine on a residential door, but the silicone construction and temperature range are specified for commercial duty.
