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.

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.

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.
I am engaged in the manufacture of groundbreaker foundation liner and timber-framed walls combine the beauty of natural materials with strong and durable construction, making them a popular choice for both traditional and modern architecture.
