Insulating concrete formwork uses polystyrene connected with a web system that allow the forms to be stacked and steel reinforced.
Polystyrene walls filled concrete uk.
Shutters are installed to brace the polystyrene as it would burst under the weight of the concrete if left un supported.
Walls are generally constructed to first floor level before filling with concrete letting it dry and going up to next storey or roof.
The readymixed concrete has to be right in order for the concrete to flow evenly throughout the formwork.
It simultaneously acts as the forming.
An insulating concrete formwork icf system becowallform is based on large hollow polystyrene block components that interlock together without intermediate bedding materials to provide a formwork system into which concrete is poured.
Membership of this organisation means that we keep up to date with the latest building information as well as ensuring that we operate to the highest standards of quality service.
With all the systems the concrete pour is an absolutely critical phase.
Polysteel is a member of the insulating concrete formwork association icfa.
The formwork is then braced and aligned ready to be filled with poured concrete.
Smartblock forms are made of expanded polystyrene eps they are an insulating stay in place formwork that speeds construction and yields a superior finished wall.
Warmerwall icf blocks are manufactured by polysteel uk ltd.
Superior walls precast concrete foundations are the best solution for residential builders looking for reliable scheduling efficient one day installation ready to finish convenience energy code performance and a manufacturer s limited warranty.
The polystyrene combined with the concrete offer provide a thermal mass allowing structures to be heated and cooled more effectively.
Once assembled the walls are supported with shuttering before the void or cavity is filled with concrete to form the wall structure.
These components come in the form of a block comprising of two leaves of eps of which the outer leaf may vary in thickness depending on the u value required.
In order to strengthen the polystyrene while the concrete is poured and then while it cures.
The support and bracing on the polystyrene blocks also has to be adequate or there is a risk of the walls distorting or even bursting open at pressure points.
The polystyrene forms are then built up on site and filled with ready mixed concrete.
Once set the concrete becomes a high strength structure and the formwork remains in place as thermal insulation with u values down to 0 11 w m k ideal for zero energy buildings.
The insulating concrete formwork icf system consists of expanded polystyrene eps components utilised as the formwork for plain or reinforced engineered concrete walls cast in situ.
