Insulating Concrete Formwork by Amvic
Amvic ICFs consist of 2 panels of 1.2 metres long, 0.4 metres high, and 65mm thick high-density polystyrene panels, spaced apart by high strength polypropylene webs. The forms provide a permanent, fully insulating, 'stay-in-place' shuttering system into which concrete is poured.
Once cast, the solid concrete core not only provides the necessary structural integrity for the building, but also excellent noise attenuation, fire safety, thermal mass and durability for the structure's lifetime.
The polystyrene panels provide the thermal insulation to the structure, with U-values between 0.24 W/mēK and 0.11 W/mēK being easily achievable.
The forms, being extremely light (only 3.5 kg each), are simple and easy to build, with all of the attendant handling and safety benefits.
Amvic is the strongest insulating concrete formwork system on the market.
The powerful combination of the patented, reversible FormLockT interlock, EPS composition, innovative web design and web spacing result in:
- A simple, strong formwork system that requires less support during installation giving straight, flat and plumb walls.
- Less wastage when compared against other ICF or building systems.
- The ability to withstand internal concrete vibration, ensuring a structurally superior wall.
Amvic ICF is the most user-friendly ICF on the market due to its innovative design which increases speed of construction, reduces labour costs and provides the highest level of performance during and after construction.
Amvic ICF walls can then be finished internally by gypsum board screwed directly to the integral webs.
A wide range of external finishes may be used including brick, stone, timber cladding, and renders. 'Through-coloured' polymer renders are the most popular form of render finish, a wide variety of colours and textures being available.
