At SMG, our mission is simple:
to create warmer, healthier, more energy-efficient homes and buildings by delivering advanced smart thermal insulation solutions that reduce energy waste, enhance comfort, and provide long-term savings.
Our Commitment at SMG
SMG brings over 25 years of professional property, maintenance and performance experience to every project.
Our Smart Thermal Insulation service is backed by:
Structured training and quality control
Full job scheduling and compliance systems
Professional reporting and documentation
Ongoing maintenance and performance support
We don’t just apply a product — we deliver a long-term performance solution for the health, comfort and efficiency of your building.
Key Benefits for Homes & Buildings
Key Benefits for Homes & Buildings
🔋 Significant Energy Savings
By reducing heat loss in winter and heat gain in summer, buildings require less heating and cooling, leading to substantial power and gas savings.
🌡️ Stable Indoor Comfort
Eliminates cold walls, hot rooms and temperature instability — creating a consistently comfortable internal environment.
🫁 Healthier Living & Working Conditions
Reduces condensation, dampness and mould formation, improving indoor air quality and supporting better respiratory health.
⚙️ Better Performance of HVAC & Mechanical Systems
Air-conditioning, heat pumps and industrial refrigeration systems operate more efficiently with less strain, extending equipment life and reducing maintenance costs.
🔨 Non-Invasive Upgrade
No opening of walls. No major demolition. No prolonged disruption. The coating is applied directly to existing surfaces.
🏠 Higher Property
Improved energy performance increases long-term asset value, compliance, and market appeal. Performance & Value
Where Smart Thermal Insulation Can Be Applied
Exterior Walls
Creates a thermal barrier on uninsulated insulated walls, eliminating thermal bridges and dramatically improving overall building performance
Interior Walls
Adds an internal thermal layer where exterior upgrades aren’t possible or where extra insulation performance is needed.
roofs
Prevents roofs from overheating in summer and losing heat in winter. Especially effective on metal, tile, and industrial roofing where heat gain is extreme.
Wood & Timber Surfaces
Protects and insulates decking, cladding, sheds and timber structures while maintaining the natural appearance.
Industrial & Commercial Buildings
Ideal for factories, warehouses, refrigeration facilities, machinery buildings, schools, storage buildings and processing plants where heat control and energy efficiency are critical.
Invisible & Heritage Applications
Translucent and invisible options available for exposed brick, heritage façades or architectural finishes where appearance must be preserved.
Why This Technology Matters in New Zealand
Many older NZ homes and buildings:
Were built with little or no exterior wall insulation
Still experience cold interiors, dampness, mould and high power bills
Struggle to meet the true intent of the Healthy Homes Standards, even when ceiling and underfloor insulation are upgraded
Smart Thermal Insulation directly addresses this missing layer in the thermal envelope — particularly where traditional wall insulation is impractical, disruptive or unaffordable.
For schools, social housing, commercial and industrial buildings, the energy, health and maintenance savings multiply rapidly across large floor areas.
What Smart Thermal Insulation
Does
Our coating system forms a high-performance thermal barrier on the surface it’s applied to.
It works by:
Reflecting radiant heat
Reducing heat transfer through surfaces
Stabilising internal temperatures
Minimising condensation and moisture build-up
Reducing the load on heating and cooling systems
The result is a home or building that is:
Cooler in summer
Warmer in winter
Healthier year-round
Cheaper to operate
Easier on mechanical systems and equipment
