INSULATION

FAQ

Insulation is a material used to reduce heat loss or gain. It helps maintain a comfortable temperature in your home, improving energy efficiency and reducing utility bills. Choosing the right insulation depends on factors like climate, budget, and the area of application.

Insulation materials are selected based on thermal resistance, moisture resistance, and fire safety. Consider the R-value, which measures thermal resistance. Higher R-values offer better insulation. Also, assess the material's compatibility with your building structure and environmental impact.

Insulation types include fiberglass, foam board, and cellulose. Fiberglass is cost-effective and easy to install. Foam board provides excellent thermal resistance for walls and roofs. Cellulose, made from recycled paper, offers an eco-friendly option but may require professional installation.

Insulation: 3 things to consider before buying

When selecting insulation, R-value is a crucial factor. It measures how well insulation resists heat flow, so the higher the R-value, the better it insulates. Consider your climate and where you'll install the insulation. For example, lofts in colder regions may require insulation with a higher R-value compared to walls in milder climates. We recommend checking local building codes or consulting a professional to determine the appropriate R-value for your project.

Insulation comes in various materials, including fibreglass, foam board, and cellulose. Each has its pros and cons. Fibreglass is popular due to its affordability and ease of installation but can irritate skin and lungs if not handled properly. Foam board provides excellent thermal resistance but may be more expensive. Cellulose, made from recycled paper, is eco-friendly and offers good soundproofing but may settle over time. Consider factors like budget, environmental impact, and specific needs when choosing the material.

Moisture can significantly affect insulation's performance and longevity. When buying insulation for areas prone to dampness or humidity, such as basements or bathrooms, look for products specifically designed to resist moisture. Closed-cell spray foam is an excellent option as it acts as a moisture barrier while providing high thermal resistance. Alternatively, ensure proper ventilation and vapour barriers are in place to protect other types of insulation from moisture damage.

Keep cosy: Find the right insulation for your space

Insulation is key to making your home warm and energy-efficient. It keeps the heat in during winter and out in summer. Here, we explore different types to help you make the right choice for your needs.

Types of materials

There are several materials to consider, each with unique benefits. Let's look at some popular options.

Glass wool insulation

Glass wool is made from recycled glass. It's lightweight and easy to handle. This type is known for its excellent thermal and acoustic properties. It's often used in walls and roofs for its soundproofing qualities. Glass wool is also fire-resistant, which adds an extra layer of safety to your home.

Stone wool insulation

Another great option is stone wool. Made from volcanic rock, it offers superb fire resistance and soundproofing. Stone wool is durable and moisture resistant, making it ideal for areas prone to dampness. It also maintains its shape over time, ensuring long-lasting performance.

Where to install insulation

Choosing where to install is crucial for maximising its benefits. Here are some common areas to consider.

Walls

Insulating your walls can significantly reduce heat loss. Both internal and external wall insulation have their advantages. Internal is less disruptive and cheaper, while external offers better thermal performance. It's essential to choose the right type for your wall construction to achieve the best results.

Floor

Floor insulation is often overlooked but can make a big difference. It helps prevent heat loss through the ground and keeps your feet warm. There are various options, including rigid foam boards and screed. Choose according to your floor type and personal preferences.

Insulation performance ratings

Understanding performance ratings can help you select the best choice. Here's what to look for:

  • Thermal conductivity (lambda value): Lower value is better.
  • R-value: Indicates thermal resistance. Higher R-values is better.
  • Fire rating: Look for materials with an A1 rating for non-combustibility.

Benefits of proper insulation

Proper padding offers numerous benefits. It reduces energy bills by keeping your home warm in winter and cool in summer. It also improves comfort by maintaining a consistent temperature. Additionally, it can enhance soundproofing, making your home quieter.
