Sealmaster Watershed


Applications

An effective threshold seal combination with hidden fixings, designed with options to suit inward and outward opening, single and double leaf, external doors.

Features and Benefits

Sealmaster WatershedThe range of threshold sections means that it is possible to finish off a range of floor finishes neatly against this aluminium section. The low profile of all the threshold sections ensures compliance with Document M of the Building Regulations and ease of access. The variety of weatherboard sections ensures that the seal can be used on period and contemporary door designs.

The channel collects water that has managed to by-pass the rubber blade seals and, through pre-drilled weep holes, this drains to the outside of the building, ensuring a high level of performance.

The contact strip combinations provide effective sealing options for outward opening doors All weatherboard and contact strips have concealed fixings and snap on covers which are available in a number of finishes. The Watershed combination seals can be used with virtually all Sealmaster stop and meeting stile seals to enable a doorset to achieve a high level of weatherability.

application guide

Sealmaster WatershedApplications
An effective threshold seal combination with hidden fixings, designed with options to suit inward and outward opening, single and double leaf external 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.

Sealmaster WatershedInward opening doors
Single inward opening doors
The door stop seal must be fitted down to the sill. The front of the threshold should be cut to fit around the door stop seal and the rear fitted directly between the jambs and tight up against the back of the stops, in line with the front face of the door.
The weatherboard should be screwed to the external face of the door. It is supplied with oversized holes to allow fine adjustment. It should be fitted up to the line of the leading edge of the stop seal blade. The WA aluminium weatherboards have snap on covers, which hide these fixings after installation. The WB &WC timber weatherboards are supplied with blade seals so that, like the WA, the fixings are hidden after installation in the traditional way.

Sealmaster WatershedPairs of inward opening doors
The door stop seal must be fitted down to the sill. The meeting stile seal should be carried to the top of the Watershed trough leaving sufficient gap for the doors to operate without striking the trough and the weatherboard cut to fit around it with 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.

Sealmaster WatershedOutward opening doors
The threshold should be installed first, between the jambs and tight against the front of the stops. The surface mounted CA contact strip door seal should be cut to size, then fitted along the bottom of the door so that the blade rests on the threshold. The CA aluminium contact strips have snap on covers which hide the fixings after installation and which are profiled to visually match the thresholds.

Drainage, bedding & additional protection
To assist drainage, the sill externally should slope away from the threshold at approximately 1 in 20. The trough should be carefully bedded in silicone sealant. The front edge of the threshold should not be bedded in sealant, as this will prevent drainage.

Sealmaster WatershedIn conditions of severe exposure the weatherboard, contact strip and stop seal carriers should also be bedded in Sealmaster Silicone Sealant.

Fixings
Threshold – 1¾'' No. 8 pan-headed stainless steel screws.
Contact strip - ½'' No.4 pan headed screws.
Surface mounted seal – ½'' No.4 pan headed screws.
