External Insulated Walls

A mortar joint of 2mm provides a stronger bond than conventional mortar joints. The thin joint mortar is quick setting, gaining strength within 20 minutes, allowing walls to be built continuously without height restrictions.

‍

The reduced area of the thin joint further improves the u-value of the wall and restricts air leakage. Air leakage tests on site show that 0.6 m³/hr/m² is readily achieved.

To complement the high-performance wall, it is necessary to consider the other elements within the construction in order to achieve low energy, low carbon sustainable homes.

‍

• Floors and roof to be designed to a high specification, where 0.11 W/m²K is easily achievable.
• Detailed attention to the junction of the dwelling to avoid cold bridging can offer figures typically Y = 0.02.
• By adopting these designs, a construction can be built to future low carbon, low energy requirements without the need for additional renewable energy components.

‍

• Low energy, low carbon homes are achievable without the need for expensive renewable energy technology.

‍

• Low maintenance costs – no expensive solar panels, damage to walls and reduced energy costs.

‍

• Lower build costs – up to 15% on framed buildings with same build time.

‍

• Quicker lead times, no bulk purchases required for servicing site.

• The fabric used in the construction is at the core of our ethos that the materials used should show ecological and sustainable benefits and most importantly provide the dwelling with a long service life with low maintenance.

‍

• We offer full technical support on design and construction, training and supervision of site staff to ensure that the project is designed and built to the clients’ satisfaction.

‍

• It is our desire to see the UK build low energy use homes following the principles of PassivHaus in design construction to the highest standards with reductions in energy usage and costly renewable energy sources.
