Sustainable Building Materials: Paving the Way for Greener Construction with LAROS

As the world grapples with the challenges of climate change, the construction industry is undergoing a transformative shift towards sustainability. Sustainable building materials play a pivotal role in this evolution, and we at LAROS are at the forefront of revolutionising construction practices. In this blog, we will explore the significance of eco-friendly construction materials and LAROS Industries, with its focus on Passive House prefab structures, is contributing to a greener and more sustainable future.


The Essence of Passive House Prefab

We are LAROS Structures, have been the Australian Passive House domain for over a decade and are dedicated to delivering high-performance, energy-efficient, and sustainable homes. Our approach involves manufacturing structural timber panels, including windows, insulation, airtight seals, and membranes, ensuring a Passivhaus standard structure that arrives on-site weatherproof and ready for lockup.


Key Features of Passive House Construction


A fundamental aspect of Passivhaus structures is airtightness. LAROS panels meet the Passivhaus airtightness standard of less than 0.6 air changes per hour, eliminating air leakage and enhancing both building performance and occupant health.


Thermal Insulation:

Continuous, thick insulation is imperative for maintaining a thermal separation between the indoor and outdoor environments. We ensure careful installation, minimising gaps to improve thermal comfort, and reducing the risk of condensation and mould formation.


Thermal Bridge Free Construction:

Heat resistance is optimised by using low thermally conducting materials, ensuring there are no thermal bridges that could allow heat to escape. This meticulous approach enhances energy efficiency and the overall performance of the building.


High-Performance Windows:

Here at LAROS Structures, we employ Döpfner fenestration products and Roma shading devices for superior Passive House performance. These windows are triple-glazed, argon-filled, thermally broken, and equipped with double seal airtightness and double low-e coatings.


Heat Recovery Ventilation:

Airtight structures require controlled ventilation, achieved through heat/energy recovery ventilation (HRV/ERV). We integrate ducting and adapters into panels during construction, ensuring a constant supply of fresh air without compromising internal temperature.


The Role of Solid Timber Panel in Sustainability

The Solid Timber Panel forms the core of LAROS Structures, utilising European spruce and cross-laminated timber (CLT) for exceptional strength-to-weight performance. Timber, a renewable resource with a minimal carbon footprint, is not only structurally robust but also aesthetically pleasing. LAROS ensures the panels are PEFC certified, sourced from sustainable Austrian forests, contributing to a sustainable and environmentally conscious construction industry.


Earthwool® Insulation: Balancing Comfort and Sustainability

LAROS prioritises Earthwool® Insulation for its structures, which is made from up to 80% recycled glass. This insulation material is non-combustible, rot-proof, odorless, and non-hygroscopic, creating a healthier and safer living environment. Knauff’s ECOSE technology ensures no added formaldehyde, making it safer for both workers and occupants. The insulation provides excellent thermal and acoustic performance, meeting the highest standards of sustainability.


Airtight Wraps and External Cladding: Ensuring Performance and Flexibility

ProClima wraps on walls and roofs provide excellent airtightness and weather tightness, optimising insulation performance and preventing air leakage. The external cladding, due to the meticulous wall structure, acts as a rain and UV shield without compromising thermal performance. Our panels come with battens, allowing for endless cladding options, providing flexibility in design while maintaining sustainability.


Why Choose LAROS?

LAROS Group’s decade-long commitment to the Passive House space in Australia sets them apart. Our passion for supplying best-in-class products and supporting all aspects of high-performance builds showcases a profound understanding of sustainable construction. By integrating eco-friendly materials, meticulous design, and a commitment to excellence, LAROS Structures is paving the way for a greener and more sustainable construction industry.
