WALL INSULATION
For builders across Melbourne, achieving superior energy performance and occupant comfort starts with the details and wall insulation is one of the most critical.

From site assessment through to installation, we’re the trusted partner builders rely on to get it right the first time.
Install Wall Insulation in Melbourne
Our team understands the complexities of site demands and delivers seamless integration of quality wall insulation that keeps internal temperatures consistently comfortable while significantly reducing heating and cooling loads.
Beyond thermal performance, wall insulation plays a critical role in acoustic comfort, helping ensure noise doesn’t travel too easily from one room to another. This means occupants can watch television, work, or relax without disrupting others elsewhere in the property, a valuable point of difference for townhouses, units, and party walls. We use high-quality Knauf Earthwool batts to deliver unparalleled acoustic barrier and thermal performance, manufactured from recycled glass fibres using bio-based binder technology, making it light, resilient, odourless, and resistant to bacteria and mould. We offer a wide range of wall insulation options in various thicknesses and dimensions to suit any property type or size, helping you deliver builds that stand out for comfort, efficiency, and acoustic performance across new builds, extensions, and renovations in Melbourne.
Why Choose SL Insulation?

Our cost-effective wall insulation batts are engineered for quick, easy installation, with consistent quality and low-dust properties that help you keep projects moving without compromise.
OTHER SERVICES
Ceiling Insulation
Up to 35% of heat loss happens through an uninsulated ceiling. Quality ceiling insulation blocks outside noise, maintains a comfortable indoor temperature, and lowers energy costs throughout the year.
Wall Insulation
Wall insulation traps millions of air pockets to slow heat transfer, keeping Melbourne homes cooler in summer and warmer in winter. It also helps reduce noise transfer between rooms, a cost-effective way to boost your home’s thermal and acoustic performance while cutting energy bills.
Pipe Lagging
Unlagged pipes waste energy and create noisy knocking and rattling sounds. Pipe lagging insulates hot water systems and air conditioning ducts, improving efficiency and reducing disruptive noise.
Underfloor Insulation
Underfloor insulation stop cold air rising through your floors. Underfloor insulation regulates indoor temperature year-round, improves comfort, and reduces heating and cooling costs in Melbourne homes.
Wall Wrap Insulation
Wall wrap insulation acts as a breathable weather barrier, protecting your home’s frame from moisture, wind, and air leaks while improving overall thermal efficiency. Essential for new builds and renovations across Melbourne.
Soffit & Sisalation Insulation
Soffit & sisalation insulation combines a reflective foil layer with fibreglass reinforcement to reflect radiant heat and protect your property from temperature extremes. A durable, high-performance barrier for soffits, walls, and roofs.
FAQs
What areas do you service?
SL Insulation services homes and properties across Melbourne, working on new builds, renovations, upgrades, and supply-only projects throughout the metro area.
What types of insulation do you install?

How long has SL Insulation been in business?
We’ve been operating since 2013, completing work for over 500 repeat customers and earning more than 50 five-star Google reviews.
Do you only work on new builds, or renovations too?
Both. We work to the scale of your project — whether it’s a full trade site for a new home, a renovation, a DIY upgrade, or a supply-only order if you’re installing insulation yourself.
I already have insulation in my home — can you replace or upgrade it?
SL Insulation specialises in new installations for new builds, renovations, and upgrades. If you have existing insulation that needs to be removed and replaced — including old, damaged, or contaminated insulation — we recommend our sister company Ace Insulation Removal, who specialise in insulation removal and retrofit projects across Melbourne.
How much heat loss can insulation actually prevent?
Up to 35% of a home’s heat loss can occur through an uninsulated ceiling alone, so quality insulation makes a significant difference to both comfort and energy bills year-round.
What's the difference between bulk insulation and reflective (Sisalation) insulation?
Bulk insulation uses trapped air pockets in batts to slow heat transfer, while Sisalation combines a reflective foil layer with fibreglass reinforcement to reflect radiant heat. Many homes benefit from a combination of both, depending on the area being insulated.
Do you supply insulation for DIY projects?
Yes — if you’d prefer to install it yourself, we offer supply-only options so you can purchase quality insulation products without booking an installation.
