Quality & Compliance

Helping you build homes that easily achieve

compliance alongside Part L and A Rating requirements.

ICF products can help you

At Altherm ICF, we understand that compliance with Building Regulations and the recently imposed obligations of Part L is crucial for you. Our Altherm ICF walls work in conjunction with complementary best-practice energy-efficient options including windows, roofs, heating systems – helping you easily achieve compliance alongside Part L and A Rating requirements.

How Altherm ICF helps you achieve compliance

U-Values

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, also acting as a permanent shutter for the concrete core. As well as delivering a U-Value of < 0.20W/m2K, for our Altherm ICF 150 and 200mm core walls, average area weighted U-values (Um) of <0.18W/m2K can be easily achieved.

Thermal Bridging

Thermal Bridging has a dramatic effect on the performance of your building and is specifically required as part of Part L, Building Regulations. With our 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 ICF is committed to supporting your design team and BER assessor by providing all the necessary technical data. We understand the importance of this information in ensuring the successful implementation of our system in your project.

Air Tightness

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

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).

Fire

By providing a 60-minute plus fire rating, Altherm ICF products are fire-resistant to very high standards. Fire Breaks are cast into the ICF wall internally and externally to compartmentalise the building in compliance with fire regulations and your fire consultant.
