Quality & Compliance

Our Altherm ICF structure complies with the Building Regulations for U-Values and thermal bridging.

The low U-Value of Altherm ICF walls is easily achieved on site as the insulation is built in, and it acts as a permanent shutter for the concrete core.

Thermal Bridging dramatically affects your building's performance and is specifically required by Part L of the Building Regulations.
With a very low thermal bridging factor of 0.04, our walls are designed to reduce energy loss through the building envelope.

Our custom-designed cavity closer works with our system to eliminate cold bridging around window and door openings. PSI values measure heat loss around these thermal bridging junctions and certified psi values factored into the DEAP calculations for Part L are included in the Altherm ICF Irish Agrément Certificate.

Altherm’s ICF provides a fully sealed system, and due to the continuous concrete core, leakages do not occur.
Any gaps in the structure that might compromise air tightness are eliminated.

Altherm ICF structures deliver air tightness levels of less than 2m3/m2.h @50kpa and current building regulations require <5m3/m2.h @50kpa.

Altherm ICF products are fire-resistant to very high standards by providing a
two-hour fire rating.

In terms of sound, high sound insulation can be achieved without additional membranes or insulation.

Once cast, the concrete core integrates with the ICF to provide superior sound insulation exceeding soundproofing requirements (>53dB).
