Silicone Render System

The K Rend Silicone range contains a powdered silicone water repellent in the formulation, which disperses rapidly during the mixing stage and does not alter the appearance of the surface of your property.

What are the benefits of K Rend's Silicone Range Technology.

Water Repellent
BBA and NSAI Accredited
Low Maintenance Required
Freshly Rendered Appearance for Longer
Allows Property Structure to Breathe
Natural Looking Finish
Extensive Colour Range to Choose From

The silicone technology significantly reduces the amount of water absorption on the render surface , whilst allowing water vapour to pass freely through the render, granting your property optimum breathability. The water repellent surface ensures a freshly rendered and aesthetically pleasing appearance for a prolonged period. Additionally , the finish is drier, therefor more resistant to algae growth and easier for you to maintain.

Rendering Benefits

Thermal Efficiency Benefits

Silicone render systems contribute to the overall thermal efficiency of a property when paired with appropriate insulation. By minimising heat loss through external walls, they help maintain a more stable internal temperature, making homes and buildings more energy-efficient and cost-effective to heat.

Long-Term Cost Savings

Although the initial outlay for silicone rendering can be higher than traditional methods, the long-term savings are significant. Thanks to its weather resistance and low maintenance requirements, property owners can avoid frequent repairs, repainting, or remedial work, making it a smart investment over time.

Resistance to Algae and Fungal Growth

Silicone render contains water-repellent properties that help prevent the build-up of algae, mould, and mildew. This ensures that the exterior surface remains cleaner for longer, even in damp or shaded areas where other render systems might quickly deteriorate or discolour.

Ideal for Coastal and Exposed Locations

Due to its resistance to salt spray, wind-driven rain, and harsh environmental conditions, silicone render is an excellent choice for properties located in coastal regions or exposed rural areas. It helps maintain the appearance and structural integrity of a building in challenging climates.
