CLADDINGS - PLY

6 comments


The exterior of the rear section of the house has Ecoply® Barrier applied, with the joints between the sheets taped for airtightness.

Ecoply® Barrier provides a weather tight rigid air barrier for drained and vented cavity systems
outside the building frame to effectively replace the traditionally used building wrap in the cavity.
Compared to traditional building wrap, Ecoply Barrier provides a higher level of protection from moisture entering into the building envelope as it forms a rigid sheathing around the building, with the cavity and cladding then placed over it. 

Additional advantages provided by Ecoply Barrier is that it can provide superior structural bracing to the building meaning that the reliance on internal wall braces can be reduced, in turn reducing the overall build cost.

Ecoply Barrier also allows the work to progress on the house interior prior to cladding installation - a real benefit especially in winter as delays due to bad weather are reduced.  Panels can be exposed to exterior weather for up to 6 months prior to installing the final exterior cladding.

Ecoply Barrier ticks the boxes environmentally as it manufactured from sustainable plantation pine, is FSC certified upon request and has a low formaldehyde emission level (E0).




The joins between the Ecoply Barrier sheets are taped.

Structural steel work has been designed to support the roof, and as a lintel for the wide door to the living area that forms the front section of the house.  Steel cross-bracing has been used in the roof plane, and the connections can be seen with Intello membrane between, and over to ensure the membrane continuously contains the building envelope. 

  

INTELLO has been fitted between the roof brace connector and the external structural
element - which in this case,  is the steel frame.
INTELLO has been fitted between the steel lintel beam and the external timber-framing ready for an extension to be taped on that will cover the roof and wall planes.

As well as timber-framed walls being installed,  block-layers are building reinforced Firth 
concrete-block walls on top of the concrete floor slab.  (The concrete block walls are for structural intent rather than a PH consideration in this situation.)






 
The concrete block masonry walls are reinforced with Eurobar steel reinforcing bars, and then solid filled with concrete. 






The interior of the concrete block walls have timber battens applied for the fixing of linings.


The shape of the living space is formed, and the block wall at the end of the space
is trapped for the lining application.

METAL ROOF

4 comments
The first section of roof has been laid to the rear section of the PH.  HI RIB trough-section roofing by Steel and Tube has been used, laid over building paper.  
Structural steel frames are installed for the roof structure of the front section of the PH.  
Attention has been paid to the management of the pro clima 'Intello' membranes, as can be seen in its placement in details around the building envelope.  This can be seen in the way it has been placed around the steel lintel-beam, and roof cross bracing connections.

While the roof is being built, concrete block walls are being erected, and wall framing continues on.  Refer to the Walls chapters of this blog for more pictures of these elements.


 



Roof trusses form the structure to the roof of the rear section of the house,
and boric treated Laserframe rafters have been used for the living area of the PH.
The Laserframe rafters extend out beyond the face of the building to form a generous eave,
that will provide solar shading.
Steel rod cross bracing is fixed to the structural steel work.
 INTELLO membrane is used between the connection and the steelwork.
INTELLO has been fitted between the roof brace connector and the external structural
element - which in this case,  is the steel frame.

The INTELLO membrane is detailed to be continuous.
This has been achieved on site by fitting strips as seen in this collection of photos.
These strips will be taped to the main membranes that will be
applied later in the construction process. 
Building paper from beneath the roofing will be managed
ready for the application of  Ecoply to be fixed to the wall.
The eave at the rear of the building.
The roofing profile, with black building paper protruding from beneath to move any
condensated moisture to flow to the spouting that will be affixed to the fascia board.


A roof window sits on the roof at the rear of the house. These views show it sitting on top of the roof, and also viewed from beneath  inside the house.




In the photo above, the building paper from the roof (viewed in the previous photo) 
is turned up behind the 'Ecoply Barrier' fixed to the outside of the framing.  
Refer to the 'Walls - Claddings' page for the functional and photographic 
information on 'Ecoply Barrier'.









The metal roof is complete, and the photovoltaic panels have been installed on top.  
They can be seen on the roof to the left of this photograph.
