One drawback of rigid board insulation is that it may not be as flexible as other insulation types, which can make it challenging to fit into irregular spaces or curved surfaces. The initial cost of rigid board insulation may be higher than some other insulation options, but its long-term energy-saving benefits often justify the initial investment.
Spray Foam Insulation is known for its ability to create an airtight barrier, providing excellent moisture resistance and enhancing the overall airtightness of the building envelope.
Applying spray foam insulation involves using specialised equipment to mix and spray the two components that form the foam. This process allows the foam to expand and fill cavities, cracks, and gaps, creating a seamless barrier against air infiltration. The benefits of spray foam insulation go beyond energy efficiency; it also helps in reducing noise transmission, as the dense foam acts as a sound barrier.
Another advantage of spray foam insulation is its durability and longevity. Once applied, it adheres firmly to surfaces and does not sag, settle, or degrade over time. This ensures long-term savings on energy costs and maintenance.
Loose Fill Insulation, which includes eco-insulation materials like natural fibre insulation, is often used for its eco-friendly properties and ease of application in irregular spaces.
These materials, along with mineral wool and recycled denim insulation, are all excellent choices for improving energy efficiency in buildings. They reduce heat transfer and air leakage, allowing for better control of indoor temperatures and reducing the reliance on heating or cooling systems. Their installation also helps in reducing carbon emissions, promoting environmental sustainability.
The installation of internal solid wall insulation involves several critical steps, including:
Preparing the wall involves cleaning the wall surface, applying a primer, and ensuring you have the necessary safety equipment to begin the insulation process.
Before starting, it's crucial to thoroughly clean the wall surface using a solution of warm water and mild detergent to remove any dirt or grease that may affect the primer's adhesion.
Applying a high-quality primer serves as a crucial step to ensure proper adhesion of the insulation material. There are different types of primers available, including water-based and oil-based options, so choose one that suits your insulation material and wall surface.
Don't forget safety measures such as wearing protective goggles, gloves, and a mask to avoid any potential health hazards during the installation process. It's advisable to work in a well-ventilated area and follow the manufacturer's instructions carefully to guarantee a successful and safe insulation project.
Accurate measurement of the wall size using a measuring tape and precise cutting of the insulation material with a utility knife are crucial steps in the installation process.
