Applications

A versatile threshold seal combination with hidden fixings and options to suit virtually all hinged and pivoted doors.

Features and Benefits

The Cyclone threshold and contact strip combinations can be used in most internal and external situations, including those with a degree of exposure requiring weather tight seals.

The Cyclone threshold and weatherboard combinations can only be used on inward opening external doors that are sheltered from wind driven rain.
With the contact strip combinations, the Cyclone can be used on external doors to comply with Part M of the Building Regulations to allow ease of access. It can also be used with the Blizzard seal and other Sealmaster stop seals to achieve an exceptional acoustic performance.
All fixings, in all the sections, are hidden to give clean, crisp lines in an attractive range of finishes.

The Cyclone threshold section is available in two low profile versions, one being symmetrical for application on top of carpet or vinyl floor finishes (section TE), the other has a flat face against which carpet or vinyl can be finished neatly (section TD).

Specialist applications include rooms with a gas flood fire suppression system installed. studio and music room doors, as well as interview rooms, where a high level of acoustic performance is required and photographic dark rooms where a light, tight seal is needed.

application guide

Applications
A versatile threshold seal combination with hidden fixings and options to suit nearly all hinged and pivoted doors.

Relationship with other products
To seal the gaps around the door effectively these thresholds should be used in conjunction with one of the Sealmaster range of stop seals such as the surface mounted Sealmaster Blizzard or the recessed Sealmaster Deluge. The gap between the two leaves of double doors should be sealed along the face of the door with an appropriate meeting stile seal such as Sealmaster Tempest. The gaps around double swing or pivot doors should be sealed with an appropriate seal such as the Sealmaster Typhoon.

Inward opening doors

Sheltered single inward opening doors
The door stop seal must be fitted down to the sill and the threshold should be notched around it.
The weatherboard should be screwed to the external face of the door. It is provided with oversized holes to allow fine adjustment. It should be fitted up to the leading edge of the stop seal blade.

Sheltered pairs of inward opening doors
The meeting stile seal should be carried to the bottom of the door, and the weatherboard cut to fit around it and the joint sealed with silicone sealant.

The doors may need to be fitted with a door selector to ensure the correct leaf closes first. In order to reduce water penetration between the weatherboards fitted to each of the doors, the gap between them should be kept as small as possible. They should both be cut at an appropriate angle to compensate for the radial throw of the door.

External exposed and internal doors
The Cyclone / contact strip combination seals give excellent performance in many circumstances but particularly when used on external doors, both inward and outward opening single and double leaf doors. This stems from its fixing position which lines up with the inside face of the door rather than the outside. Cyclone seals are recommended for the most exposed situations as its vertical upstand gives excellent weatherability but still allows wheelchair access. The adjustable contact strip, CB or CD is fitted to the inside face of the door. The threshold TD or TE is positioned so that the internal face of the door is located over its centre line. The threshold is notched around any fitted door stops. Any fitted door stop seals are cut to finish on top of the threshold.

Double swing and pivot doors
The adjustable contact strip, CC is fitted to the inside face of the door. The threshold TD or TE is positioned so that the contact point of the contact strip CC is located over its centre line. Where floor springs are used the threshold is cut to enable the cover plate to be lifted for maintenance without disturbing the whole seal.

Drainage, bedding & additional protection
The threshold and adjustable contact strip are bedded in and notched ends of the threshold sealed with silicone sealant.

Fixings
Threshold – 1'' No. 6 countersunk screws.
Contact strip - ½'' No.4 pan headed screws.
