Lath and Plaster Walls Renovation: A Comprehensive Guide to Energy Efficiency

When it comes to renovating lath and plaster walls, there are several key steps you can take to ensure your home is energy-efficient and sustainable for years to come. One of the most effective ways to achieve this is by implementing passive house design principles.

A water-resistant barrier, also known as a 'raincoat' for the house, is installed on the roof to prevent damage from rain and wind. All gaps and staples are then taped over to prevent air leaks and ensure a tight seal. The interior and exterior walls are sealed using an airtight wrap, which helps to prevent heat loss and reduce energy consumption.

Insulation plays a crucial role in passive house design, as it helps to regulate internal temperatures and reduce the need for heating and cooling. However, if there are more than five per cent of gaps within the insulation layer, performance can drop by as much as 50 per cent. This is why comprehensive insulation and sealing are essential components of passive house design.

In addition to insulation, passive houses also require a mechanical ventilation system to bring fresh air into the home, reduce humidity, and filter out dust and other allergens. This system helps to create a healthy and comfortable indoor environment while reducing energy consumption.

While passive houses are more expensive to build than traditional homes, they offer numerous benefits, including reduced energy bills and improved overall sustainability. With their modern design and cutting-edge technology, passive houses are the perfect choice for homeowners who want to reduce their environmental impact without sacrificing comfort or style.

In this article, we will explore the key components of passive house design, including insulation, sealing, and ventilation systems. We will also discuss the benefits of passive house design and provide tips on how to achieve energy efficiency in your own home renovation project.

By following these steps and incorporating passive house design principles into your lath and plaster walls renovation, you can create a sustainable and energy-efficient home that is perfect for generations to come.
