House Joubert – Langebaan – Light Steel Frame House
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.
House Hanekom – Solid Wall Light Steel Frame
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 cast floor slab and after the panels were leveled 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 clad 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 only 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.
House in Fresnaye
MULTI STOREY HOUSE in FRESNAYE
Steel House Construction – This house was located on a corner erf, size only 320m2. The site was very congested and the Light Steel Frame building method would make the building operation far more conducive than conventional building.
The old building foot print still had the old foundations on it which made the construction of a raft foundation more suited to the site.
The installation of the ground floor LSF and H/R columns only took two days. A Voidcon Decking System, suitable for our application was implemented. The system comprises of galvanised steel profiles which are laid in position, into which 25Mpa concrete is poured. The concrete provides strength, whilst the steel provides stability.
The design of the house was complicated with a large high window frontage. Another special feature of the house was the swimming pool on the first floor which was casted in reinforced concrete.
The installation of the LSF wall panels commenced and was anchored to the first floor slab.
The external walls were made up of 102 mm cavity batt insulation, 11mm OSB board, Saturator, Mentex Mentlath metal galvanised mesh, Tyvek moisture membrane and 10mm two coat SFH Stucco Plaster.
The internal walls consist of 15mm thick Firestop gypsum board with a full skim of skimstone. This wall with an overall thickness of 133mm has an R Value of 3.69 and a fire rating of 30 minutes. In all the wet areas such as bathrooms and kitchen 9mm fibre cement board was used.
The design of the walls insulating layers reduce the building’s energy requirements for heating and cooling. Achieved a 17% to 20% improvement in energy efficiency, compared with those of conventional designs the building heats up faster in winter and cools down faster in summer.
The roof was designed in LSF to accommodate colourbond roof sheeting with Monier undertile waterproofing membrane.
The speed of construction, the high quality finishes, energy efficiency and the clean site with minimal waste all contributed to the satisfaction of the client.
