Sustainable Living with Swistherm from Alumasc

Swistherm External Wall Insulation (EWI) from Alumasc has been chosen for a residential project in Wales which has been built to Passivhaus standards.

The project, named Ty Haul, met the initial design brief to meet AECB requirements at Gold level.

In meeting these standards, Ty Haul also became one of only a small number of properties in the UK to comply with the Passivhaus principal.

Passivhaus promotes energy efficient construction of residential buildings.

It requires high levels of insulation, air quality and sustainability, using efficient components and a whole-house ventilation system to achieve low running costs.

The thermal performance of Alumasc's Swistherm EWI system was key in its specification as part of an environmentally sound construction package.

Alumasc approved contractor Eaden Homes, installed 350m of Swistherm which is a durable, lightweight, thin coat render system, perfectly suited to solid wall construction.

Swistherm is weather resistant and vapour permeable, and eliminates internal condensation and reduces energy consumption.

Insulated slabs are fixed directly to the substrate and finished with a choice of silicone or mineral-based topcoat.

The use of 240mm extruded platinum polystyrene insulation achieved a U-value of 0.10, exceeding the Passivhaus requirement.

The insulation panels are also available in a variety of additional materials including mineral wool and highly sustainable natural cork for environmentally sensitive applications.

Swistherm offers a range of decorative finishes and more than 400 colours and toning shades.

Silkolitt ST Silicone render in white was the chosen finish for Ty Haul, providing an attractive yet robust defence against the property's coastal location.

BBA approved and fully warranted with a life expectancy in excess of 30 years, Swistherm is manufactured to ISO9001:2000 and ISO14001:2004 Quality and Environmental Management standards in accordance with Alumasc's commitment to sustainable building practises.
