Alternatives to Conventional Wall Rendering Systems
Wall rendering is a popular form of wall finishing that is used to improve the look and feel of interior walls. It involves applying a layer of material to the surface, usually cement render or clay-based mortar, which gives an attractive finish as well as added protection for the wall.
Conventional wall rendering systems are common but there are alternatives available that can provide a more sustainable or cost-effective solution. This article will explore some of these alternatives in detail.
Autoclaved Aerated Concrete (AAC)
Autoclaved aerated concrete (AAC) blocks are lightweight masonry units with excellent insulation properties and fire resistance. They come in various shapes and sizes and can be used as an alternative to traditional wall rendering systems. AAC blocks have a high thermal resistance, making them ideal for use in warm climates, and they come with a range of finishes including stucco, brick slips and paintable render.
Structural insulated panels (SIPs) are pre-fabricated building components made from two layers of rigid foam insulation sandwiched between two structural skins. SIPs are an excellent alternative to traditional wall rendering systems as they provide superior insulation performance and require significantly less time for installation. They also offer greater flexibility in terms of design options and can be used on both interior and exterior walls.
Exterior Insulation Finishing System (EIFS) is a composite cladding system that consists of an insulation board, reinforced mesh and acrylic-based coating. The purpose of EIFS is to provide an additional layer of insulation on exterior walls, which helps reduce energy costs. This type of wall rendering can be applied directly onto the existing substrate or over new framing, making it ideal for renovation projects as well as new construction.
Brick veneer has long been used as an alternative to conventional wall rendering systems as it provides a durable and attractive finish with excellent thermal performance. This type of veneering involves laying individual bricks either in their natural state or covered with a coating such as stucco or masonry paint. It is a popular choice for both interior and exterior walls and can be easily maintained over the years.
Lime plaster is an ancient form of wall rendering that has been used for centuries in various parts of the world. It provides a natural finish with excellent breathability, making it suitable for both damp and dry climates. Lime plaster also offers good fire resistance and thermal insulation properties, making it ideal for energy-efficient homes.
When it comes to alternative wall rendering systems, there are many options available that provide superior insulation performance and aesthetic appeal. Autoclaved aerated concrete (AAC) blocks offer lightweight yet durable masonry units with excellent insulation properties, SIPs offer superior insulation performance, EIFS is a composite cladding system that provides an additional layer of insulation and brick veneering and lime plaster are traditional methods that provide natural finishes with excellent breathability. Regardless of which option you choose, it is important to ensure your walls are properly rendered for the best results.
