This Project was built in Langebaan with exceptionally sandy ground conditions, hence we had to use a raft foundation. The concrete foundations were done using Geoplas flooring modules which consist of recycled plastic modules. This system raises the slab off of the ground and creates ventilation (space) which can be used for services. This method is very useful not only to reduce energy loss but also adds to the “green factor” in construction. This client is all about green living energy saving and interested in the speed of the construction method. With the design of the roof and insulated walls we achieved a 17 to 20 percent improvement in energy efficiency compared to conventional designs.
This project once again shows the ability of Light Steel Frame Housing.
This single story Residential House 296 m2 house has a high end internal finishing with solid walls. The client was interested in the concept of a “green” house, with the least amount of material waste.
They further agreed to use the Geoplast Flooring Module which consists of recycled plastic modules which raises the slab off the ground and creates a ventilation ‘space’, which can also be used for services. This method is very useful in reducing energy loss, a concept of construction that supports New World Steel’s philosophy of alternative building.
The Light Steel Frame wall panel were installed onto the newly casted floor slab and after the panels were levelled the frames were fastened to the slab with chemical anchor bolts. The Light steel Roof, designed to receive concrete roof tiles then followed.
The wall panels were then cladded with 6 mm fibre cement board, both internally as well as externally. During this operation the first fix electrical and plumbing work was completed.
Holes with a diameter of 50 mm are then drilled into the inside fibre cement board. Both sides of the panels were then braced to allow the cavity to be pumped full of lightweight concrete with high density polystyrene balls. This solid wall has an overall thickness of 110 mm and an R Value of 1.10. The wall system has a fire rating of 2 hours.
The external face of the wall then received a glass fibre reinforcing mesh embedded into a base plaster layer, with a further 4 mm skimcrete finishing plaster. The internal walls are fully skimmed with Skimstone.
The walls then get one primer coat and two coats of waterproof acrylic paint.
The client received the keys to the house after 12 weeks. They were happy with the outcome of the project and in particular the insulation of the house and the minimum impact the construction had on the surrounding environment.
KFC Kuilsriver – Etics
This project was a quick turnaround project completing from ground to open doors in 8 weeks. ETICS was used with the light steel on this project. ETICS system is fast gaining ground in the alternative building technology market, with architects and engineers recognizing its benefits including increased insulation of buildings against energy loss, the multiple options it provides to the intricate features of specific façade designs, as well as the provision of actively contributing to the conservation of nature and natural resources. With Light steel frame construction there are many cladding option in cladding, finished looks as well as insulation.
Smokey Grove House
This project was a fairly simple, “Natural Farm House” built on a farm just outside of Tree Sisters.
The clients had seen the Light Steel Frame concept and decided that they wanted a “Green” house, with the minimum disruption of the natural farm environment whilst construction was in progress. The only special requirement was that the client wanted exposed “timber” trusses internally.
Because of the extreme temperature in the area it was imperative that the house would be as insulated and energy efficient as possible. The conclusion was walls with an overall thickness of 133mm, an R Value of 3.69 and a fire rating of 30 minutes.
The client was very happy with the final outcome.
