No matter what kind of design challenges you are considering, you will find that the Amvic ICF system has the answers.

 

Certification

 

Amvic ICF is certified by the British Board of Agrement, Certificate No 10/4809. Amvic ICF is accepted by Homebond and Premier Insurance.

 

Protection

 

Amvic ICFs are also manufactured using only approved EPS flame retardant bead with providing up to a 3 hour fire rating.

Amvic structures are constructed with non-organic materials, which greatly minimises the growth of mould and mildew.  Also, the impermeable walls prevent the entry of dust, pollens and pollution.

 

Superior Insulation

 

Amvic ICF is manufactured using Expanded Polystyrene (EPS) as the insulating medium. EPS eliminates the problems of air borne glass fibre, insulation settlement and performance deterioration common in other insulating systems. EPS provides a proven stable insulation barrier which does not deteriorate in time, unlike many others materials on the market.

By definition the insulation envelope of the building is absolutely complete when building with Amvic ICF, in contrast to all other building system which require manual site intervention to install the thermal insulation after the structure is built. In addition there is no convection loss of heat within the wall as the insulation is in intimate contact with the structure.

 

Air-tightness

 

Current Building Regulations set standards for the air tightness of structures, measured using an Air Permeability Rating. A number of 7 is the required minimum and 3 being required for passive homes.

Because this is a poured concrete method of construction the structure is effectively monolithic, thus air-leakage is reduced to an absolute minimum. Amvic ICF is extremely airtight, with a typical structure experiencing an air permeability rating of 2 or less.

 

Thermal Bridging

 

Thermal modelling of Amvic ICF standard details has shown that the heat loss at junctions inherent in most other building systems is largely eliminated, with many junctions showing a negative loss factor. In addition the risk of mold growth due to interstitial condensation is eliminated.

Because of its superb insulation characteristics, inherent air tightness and excellent thermal bridging performance, Amvic ICF provides the basis of an A3 rated home, all as standard!

 

Sound Barrier

 

The mass of the concrete within the Amvic ICF system makes for amazing sound absorption with typical sound reduction of up to 57 dB across the finished wall. This is far in excess of the requirements of the building regulations and makes for comfortable homes and harmonious relations with the neighbours!

 

Design Flexibility

 

Amvic ICF have superior engineered spanning capabilities, making them ideal for long insulated window and door lintels, as well as for ground beam applications. They are also extremely flexible in design making curved, square, plumb and straight walls easily obtainable. In addition, exterior and interior wall finishes are easily attached.

 

Commercial Applications

 

For commercial construction, Amvic ICF are used primarily for the structure’s exterior walls but also often for interior walls to provide compartment walls or acoustic, thermal and fire barriers between areas. Amvic ICF is certified for multi storied structures subject to engineering considerations.

 

Residential Applications

 

For residential construction, ICFs are typically used for the structure’s exterior walls from foundation to wallplate, party walls and basements. ICFs can also be used in combination with almost any other form of construction.

 

Environmental Factors

 

Amvic ICF structures combine the benefits of expanded polystyrene (EPS) insulation and concrete thermal mass. This highly effective combination of materials minimizes temperature fluctuations by absorbing and storing heat.  This results in over 75% reduction in running costs which results in an equivalent reduction in harmful emissions.

Construction waste is also dramatically decreased to less than 2%, less than half of most competing ICFs and much lower than traditional building systems.  The polypropylene webs molded into the Amvic forms are made from 100% recycled plastic, making Amvic forms 60% recycled material by weight.

Amvic ICF is manufactured from EPS which is certified to be both CFCs and HCFC free. At the end of their very long life, the main components of an Amvic ICF structure can be re-cycled and reused.
