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 stops 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?
We install a full range of insulation solutions including ceiling insulation, wall insulation, underfloor insulation, Sisalation (reflective foil), wall wrap, and pipe lagging — using materials sourced from over 15 Australian suppliers.
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.

Has SL Insulation been featured anywhere notable?
