Cavity Wall (Retrofit) Insulation

Enhancing Home Energy Efficiency through Insulating Existing Walls

Insulating the walls of an existing residence is a pivotal aspect to consider, given that a substantial portion - up to 40% - of a home's heat can be dissipated through inadequately insulated walls. Your exterior walls serve as a vital shield, safeguarding your living quarters from the harsh external climatic conditions. By integrating thermal insulation into your exterior walls, you can effectively erect a barrier that mitigates heat transfer within your home, ensuring optimal energy efficiency.

Wall types

  • Brick Veneer

  • Weatherboard/ Timber Clad

  • Solid Besser Block

Enhancing Thermal Mass and Efficiency of Existing Brick Veneer Walls

Insulating existing brick veneer walls, comprised of an exterior brick layer and an interior timber or steel framework, is paramount for augmenting thermal mass and efficiency. During summer, the external bricks can accrue heat, radiating it well into the evening, whereas winters, they retain coldness, drawing away precious warmth from your home. This hinders the maintenance of a cozy indoor temperature. By incorporating wall insulation, you can shield your home from these temperature fluctuations and elevate its overall energy performance.
 
Despite reverse brick veneer construction, prevalent in Europe, inherently offering greater thermal efficiency due to the brick's internal placement and the timber frame's exterior location, robust insulation remains indispensable for preserving ideal indoor temperatures.

Safeguarding Optimal Comfort in Timber Framed Walls

The insulation of timber framed walls is imperative for ensuring utmost residential comfort, given their lightweight construction. Plasterboard, a ubiquitous interior wall lining in Australia, can also serve as an insulation medium, bolstering energy savings. While foil-backed gypsum board (gyprock) was once favored in timber-clad homes for insulation purposes, it has proven ineffective. Conversely, granular blown-in insulation offers a viable solution for insulating existing weatherboard homes.
 
Upgrading Uninsulated Besser Block Walls: Addressing Fire Safety and Moisture Management Needs
Numerous Besser block homes still lack insulation, but ALLTEK ENERGY simplifies the process by expertly blowing in granulated insulation to fill the block stack gaps. Furthermore, we offer sealing services to coat the exterior blockwork with a water-resistant product, safeguarding against moisture infiltration.

Installation Process for Insulating Existing Walls: A Comprehensive Guide

Insulating Brick Veneer Walls: We expertly inject insulation material into the wall cavity, accessible from the roof or designated wall points. This ensures the entire width of the wall frame, including window perimeters, is adequately insulated. When needed, we delicately remove bricks near windows, inject insulation, and then precisely replace and re-mortar the bricks to maintain their original appearance.
 
Transforming Weatherboard or Timber-Clad Walls: To avoid costly gyprock removal, we adopt an innovative approach. By strategically drilling holes into the gyprock and pumping insulation into the voids between framing members, we efficiently fill the wall cavity. This meticulous process, though labor-intensive, delivers an R-value surpassing standard requirements, ensuring optimal comfort during Canberra's extreme weather conditions.

Boosting Energy Savings with ALLTEK ENERGY's Granulated Blow-In Insulation

At ALLTEK ENERGY, we excel in delivering premium insulation solutions that significantly enhance the energy efficiency of both new and older homes. Our granulated blow-in insulation, made from eco-friendly mineral wool fibers sourced from natural and recycled materials, is an exceptional choice for optimizing thermal insulation and fostering a cozy living space.
 
Our blow-in insulation boasts a green profile, crafted meticulously from mineral wool fibers derived from eco-conscious sources like basalt rock and repurposed steel slag. This sustainable composition not only enhances your property's performance but also aligns with environmental stewardship, contributing to a greener tomorrow. Its inherent non-flammability safeguards your abode against fire hazards, while simultaneously offering formidable defense against moisture penetration and pest infestation.
 
Our granulated blow-in insulation stands apart with its exceptional adaptability, making it the go-to choice for insulating pre-existing structures without extensive structural alterations. Its loose-fill design facilitates seamless installation, particularly in inaccessible areas like roofs and wall cavities. Leveraging specialized machinery, our skilled team efficiently distributes the insulation into the tiniest crevices, expediting the process, curbing labor expenses, and minimizing disruption to residents.
 
Renowned for its unparalleled thermal insulation properties, our insulation surpasses expectations even in confined spaces with shallow cavity depths, like roofs and walls. It remains steadfast against compaction over extended periods, preserving its optimal thermal performance year after year. By opting for our insulation, you invite a consistently cozy indoor ambiance while realizing substantial energy savings, fostering a more sustainable lifestyle.
