Doors & Openings

The structural integrity of doors and openings is achieved by placing additional fastening and reinforced framing around them.

This framing is typically made by using boxed SRP™ Stud, extra SRP™ Stud, higher BMT SRP™ Stud, un-punched SRP™ Whisperwall™ Stud for SRP™ Whisperwall™ and/or timber framing.

NOTE: Only untreated timber framing shall be used in direct contact with any galvanized SRP™ products. If it is unavoidable to use treated timber, a separation barrier between the galvanized SRP™ product and the treated timber shall be used.

The standard details, noted below in any combination [see examples in FIGURE 23] are applicable, for door openings max 1000mm wide [max door size 900x2000 45kg] and internal partition window openings up to 1500mm wide, used in maximum of 3m tall partitions [see below FIGURE 20] constructed using minimum 63.5mm SRP™ Studs. Ensure that opening size allows for timber or aluminium joinery dimensions. Doors or openings in taller partitions or with sizes outside of the above dimensions or top hung doors/openings require specific design.

Methods of Mounting Door Jambs

For vertical reinforcement, also referred to as SRP™ Jamb Studs, the most commonly used and recommended practices to use are:

DOORS OR OPENINGS UP TO 1000MM WIDE

V1. Steel SRP™ Stud with a timber Stud [FIGURE 21] or V2. Two Steel SRP™ Studs with a timber insert [FIGURE 21].

OPENINGS WIDER THAN 1000MM

V3. Use two SRP™ Steel Studs together with a timber Stud, fastening the timber and the first adjacent stud with L Brackets top and bottom [see FIGURE 21].

The timber width should match the stud width and height. The timber insert height matches the door jamb height. Where necessary use the L bracket to allow for vertical movement.

Lintel Detail Information

Lintel detail for openings 1000mm wide or Less and for openings wider than 1000mm - Option H3.

The timber and/or steel SRP™ Studs are secured to the top SRP™ Tracks using the permanent fastening holes of the SRP™ L Bracket [FIGURE 1]. For 150mm SRP™ Studs always use two SRP™ L Brackets side by side. If there is significant localised point load above the opening, the fastening of these SRP™ Studs to the top SRP™ Track may need to be avoided, or the use of the slotted hole of the SRP™ L Bracket can be used to allow for movement [see FIGURE 1]. Consult SRP™ and/or a structural engineer for specific design for these situations.

NOTE: Only untreated timber framing should be used in direct contact with any galvanised SRP™ products. If it is unavoidable to use treated timber, a separation barrier between the galvanised SRP™ product and the treated timber should be used.
