Weymouth Self-build Passivhaus
The sway frame is going together beautifully. The timber frame team have bolted the base plates to the concrete slab, and slotted the glulams into place.
The sway frame has been designed and built to carry the weight of the triple glazed south facing units, and to stand up to the prevailing south westerlies.
The Passivframe
The timber structure is a work of art and watching the frame being assembled on site is fascinating.
These are the glulam beams that cantilever out over the ground floor to provide structure at first floor.
MVHR duct routes are pre-cut in the frame. You can see the holes in the floor joists ready for the duct work.
We have walls !
The timber frame team have been on site this week and have drilled and anchored the sole plate to the slab creating an airtight seal.
They have started to erect the external walls from 300mm (pre-cut factory made) I beams.
The frame is being erected at a cracking pace…..
The first concrete delivery arrived at 7am Tuesday. (1 of 4)
The soon to be hidden pipes and mesh.
The concrete polishers hard at work.
After a day of power floating the floor has set beautifully.
It has been a busy week.
The radon barrier (yellow plastic sheeting) was carefully laid over the top of the sand blinding.
EPS 70 insulation was laid in 3 layers of 100mm. The hot and cold water pipes were chased into the top layer of insulation. The DPM was laid over the top of the insulation, and then the underfloor heating installed to the entire ground floor area.
The scaffolding team have erected a temporary structure over the footprint and our very good friends Rob and Sandra gave up their evening to help us tie down the canopy over the frame allowing for a watertight environment when pouring the slab.
The timber frame arrived today from the woodworks in Gloucestershire as pre-cut factory made I beams and joists.
