External plaster, or render, has been used for nearly 10,000 years. With just a few strokes of a plasterer’s arm, it can transform an old house into something elegant and modern. This transformation, when combined with external insulation, can be both aesthetic and comfortable.
These same benefits apply to new builds, but rendering a home can be difficult to do right and hard to maintain.
Benefits Of Rendering A House
While many materials for exterior wall cladding will soften with time, the render is very durable. When the render is finished and flawless, it is at its best. This can be avoided with careful design and specification.
1. It Allows The Building’s Air To Circulate
Understanding how your building breathes is the key to achieving your perfect vision. Although it may seem strange to call a building a “breathing one”, all buildings absorb and release water. This is called its breathability. The moisture isn’t from driving rain, although this does contribute to it. It is mostly water vapors produced by breathing, cooking, and showering.
The walls of your house are the main conduit for moisture. Older buildings, particularly those without DPCs (Damp Proof Course), are extremely moisture-permeable and depend on this to dry. The render that you apply to the exterior of your house must match the airflow of the walls. Otherwise, you could trap moisture inside the structure.
2. It Is Suitable For Both Older And Modern Buildings
Traditional and modern lime plasters work well with older buildings. Modern cavity walls can also be used. You will get no dampness or mold in your home thanks to a vapors open render (breathable).
Water can get trapped by exterior paint or non-breathable render on your walls. This can cause blistering and failure of the top finish, which could look like an outbreak.
3. Detailing Is Important To Avoid Cracking And Staining
The specification is key to breathability. This is the first step. Next, make sure you don’t stain or crack the surface. This is about detail.
Buildings shrink and grow as the temperatures fluctuate between day and night, winter and summer. Therefore, expansion joints must be carefully placed to allow movement between sections and not in the render. This will prevent your gorgeous surface from cracking.
Weathering stains around windows and gutters are worse than crack. This can be prevented by careful detailing, especially around doors and windows, and making sure your gutters work properly.
4. It Can Increase Thermal Performance
Render with exterior Insulation is a great choice. This insulation is typically attached to the exterior of a house to provide waterproofing.
Wrapping walls up can improve both thermal performance and air tightness. This allows for a more sustainable renovation without the need to replace walls.
5. Professional Installers Will Make Sure You Get A Flawless Finish
Do your research and find a skilled, reputable installer. A successful render is dependent on the age of your project. External insulation can make your home look beautiful and cost-effective to heat if it is properly installed.
