Insulation doesn’t have to come from heavy, carbon-intensive systems. By combining lime with plant fibers, Insulcote creates a breathable base coat that improves comfort, reduces cracks, and supports healthier buildings.
Reimagining the base layer
In most construction systems, base coats are treated as purely structural — strong, heavy, and sealed. But in humid climates, those layers can trap moisture and increase thermal discomfort.
Insulcote is designed to rethink that role. As an insulation render, it acts as a breathable foundation that supports both performance and longevity.


Why plant fibers matter
Plant fibers change the way a mineral plaster behaves. Reinforcing lime with fibers increases flexibility and crack resistance, while also reducing weight. That means less stress on walls and a more stable surface through temperature and humidity shifts.
The fibers also improve thermal and acoustic qualities, helping walls buffer heat during the day and soften noise inside living spaces.


Comfort without compromise
Insulcote is best applied directly onto brick or rough plaster. When used as a base layer, it enhances insulation and breathability before finishing coats like Purecote or Finoplast are added.
It can also be finished as a top layer when a more tactile, fiber-exposed texture is desired — giving designers another option for natural, expressive surfaces.
The smartest finishes today aren’t the hardest ones—they’re the ones that stay stable in real climate conditions. Breathable mineral systems with fiber reinforcement reduce weight, regulate moisture, and improve crack resistance. That combination is exactly what we need for long-term performance in tropical builds.

Building lighter, building smarter
Altarize materials are developed to reduce environmental impact compared with conventional cement and sand systems. Early performance data shows significant reductions in weight and carbon emissions, while enhancing durability and weather resistance.
Insulcote embodies that direction: a low-impact base coat that supports comfort, strength, and long-term performance.
