PHS Apollo 2 Vapour Control Membrane

Apollo 2 Membrane

Internal Vapour Control Membrane for floors, walls and lofts.

Product Details

Apollo 2 Control Membrane offers exceptional value and performance. Often used internally on timber frame roofs, walls and ceilings and on masonry building timber roofs. It forms an airtight layer within the building and acts as a vapour control layer.

In building construction, a vapour control layer with a fixed SD of 27 is used to prevent moisture and cold air from penetrating walls or roofs and warm air from leaving.

Fixing a membrane on the walls, ceiling, and loft of a building will drastically reduce energy bills and increase the comfort of the building.

Features & Benefits

• Moisture control – A vapour control layer with a fixed SD of 27 prevents moisture from entering walls or roofs, which can lead to mould, rot, and other types of water damage.
• Energy efficiency – A vapour control layer can help to maintain the effectiveness of insulation and reduce energy loss by preventing moisture from entering walls or roofs.

Use Cases

Apollo 2 is ideally suited as a VCL for new build roofs, ceilings, timber-frame walls and suspended floor upgrades.

Apollo 2 Installation Guidelines

• For bonding barrier overlaps, penetrations and repair spots, PHS Argo Joining Tape or a similar tape is recommended,
• For connections to concrete or masonry PHS Internal Adhesive Sealant is recommended,
• Ensure there is a 100mm overlap of the membranes and tape with PHS Argo Joining Tape or another suitable tape.

1. The Apollo membrane is applied to the building envelope on the warm side of the insulation.
2. The membrane should be rolled out to the correct length and cut with a sharp knife.
3. The membrane should be applied to the timbers cross-wise to the joists/rafters, with the graphics facing the installer. 970 Double Sided tape at 400-600mm centers should be used, otherwise staple every 150-200mm.
4. Creases should be removed and reasonable tension applied to the membrane.
5. The membrane should overlap by approx 100mm the membrane graphics on the membrane mark the 100mm spot where the membranes should overlap.
6. The membrane should be extended approx. 100mm down the external wall without any stress on the material.
7. A 6-8m bead of Fortax 6400 sealant should be applied to the masonry surfaces to fix the membrane.
8. Gently press the membrane against the Sealant and allow to dry.
9. Ensure there is sufficient stress relief in the membrane corners and trim back accordingly.
10. Any overlaps should be joined with PHS Argo Joining Tape.
