Construction on the Passive House building site took a break over the 3 week Christmas holiday period, and this week the house has grown considerably - and quickly - with the installation of the pre-cut and nailed 'Laserframe' timber framed walls.
Laserframe Structural Timber is kiln dried, and is a structurally graded timber for residential and commercial construction of wall frames for general indoor load bearing applications. The pine used is grown in sustainably managed plantations, and is available in SG8 and SG10, and can be treated to different hazard classes including; H1.2 Boron (pink) and H3.2 CCA (green).
Also seen in these pictures is the pro clima Intelligent Airtightness System (IAS), which is a core part of the construction for this Passive House. The unique airtightness and moisture control properties of the INTELLO vapour check membrane prevent uncontrolled air infiltration or leakage through the building envelope. The world-wide patented system has the ability to become more diffusion open or tight as required ensuring insulation stays dry and the building envelope is protected from possible structural damage due to moisture.

which is used as the connection strip between ground level and first floor for the
ease of installation of the Intelligent Airtightness System (IAS)
The white strip is the pro clima INTELLO PLUS connection strip
fitted between the frames.

At this stage of the project, Firth concrete-block walls are being built, structural steel frames are being erected and fixed, and the second section of the house is ready for its timber framed walls. The Laserframe timber arrives on site fabricated in pre-cut and pre-nailed panels ready for speedy erection.

and the structural steel has been positioned in place for the
structure over the living areas of the middle section of the house.

The Ecoply Barrier can be seen fixed to the outside of the timber framed walls.

of the timber framed walls.
The edges and joins of the sheets are taped for air-tightness.
