 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.  

These photos show the pro clima SOLITEX EXTASANA wall wrap (blue/black) 
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.

Carters timber framing - the pink timber is H1.2 Boron and the green timber is H3.2 CCA. 

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.

Timber framed walls are being erected, concrete block walls are being laid, 
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. 

The  pro clima SOLITEX EXTASANA wall wrap (blue/black)  is wrapped around the timber framing, and sits ready for future window installation. 

Pro clima SOLITEX EXTASANA wall wrap (blue/black) is wrapped around the 
edge of the floor framing.  Ecoply Barrier has been fixed to the outside face 
of the timber framed walls. 
The edges and joins of the sheets are taped for air-tightness.

The builders!

What a job! As well as its low thermal capacity, timber frame construction has several other advantages over masonry cavity walls. Because the insulation is incorporated within the thickness of the frame, a greater thickness of insulation can be provided. An external wall cavity is not necessary in timber framed house construction, as long as an appropriate vapour control layer is incorporated on the warm side (in winter) of the insulation. Amazing! Thanks for sharing.

Looking good. In contrast to traditional masonry construction, timber house construction is light in weight which allows the building envelope to heat up very quickly. In a house, where heating is intermittent, this fast response can result in increased comfort and energy saving.

I liked the way the construction has been done. Houtskeletbouw (timber frame) homes have their own uniqueness and benefits. They provide great relief in almost all the weathers provided the built is done by experts and using good quality materials. Enjoyed reading the post and thanks for sharing the minutest details.
