Video Series: Tips and tricks for wrapping and sealing your building.
In the construction of a house, the thermal envelope insulates and protects the inside of the house from outside weather conditions.
This video series demonstrates a range of building wrapping and sealing techniques, which (when combined with insulation) help to maintain a comfortable temperature inside the house, stop unwanted air entering and exiting the house causing hot or cold draughts, and provide moisture control and water protection.
Please note: Where you have a wall frame sitting on a concrete slab, the wall wrap is carried past the bottom of the wall frame, over the edge of the slab and is attached to the concrete by a continuous bead of grey polyurethane sealant. The wrap is pressed lightly to stick to the bead of sealant so that a secure weather seal is achieved. Any excess wrap below the seal can then be trimmed.
Video Series: How to construct a Green Roof
Green roofs offer a range of benefits. They are able to soak up more water in extreme weather events, as they act like a sponge soaking up water and then releasing it slowly once they are saturated, they help to keep the outside of the home cooler during hot weather and they contribute to biodiversity.
This video series explains how an extensive green roof is constructed. An ‘extensive’ green roof has a shallow growing medium that can grow small plants, whereas an ‘intensive’ green roof has a deeper growing medium and can grow larger plants like shrubs and trees. The support structure for an intensive green roof needs to be much stronger than what is required for an extensive green roof.
