Long-Term Investment

Attic insulation is a wise investment in your Dublin property. Not only does it offer immediate energy savings, but it also enhances your home’s resale value. 

Potential buyers appreciate energy-efficient features, and a well-insulated attic can be a significant selling point, giving you a competitive edge in the real estate market.

All-Weather Protection

Home insulation provides a robust defence against Dublin’s ever-changing weather. 

During chilly winters, it acts as a thermal barrier, retaining indoor warmth and reducing heating costs. In the summer, it prevents external heat from infiltrating, maintaining a cool and comfortable environment without excessive air conditioning.

Beyond temperature regulation, insulation safeguards your home against ice dams during cold spells. By maintaining an even temperature in your attic, it minimizes snowmelt and ice buildup, preventing potential roof damage and leaks.

Quick Return on Investment

The upfront cost of attic insulation is an investment that pays for itself relatively quickly. With the energy savings you’ll enjoy, the insulation cost can be recouped within a few years. Beyond that, you continue to benefit from reduced energy expenses for the life of your insulation.

Loft Roll Attic Insulation: Affordable Comfort for Your Home

When it comes to insulating your attic, there are several options available, each with its unique advantages. One popular and effective choice is loft roll insulation, a versatile and widely used material in Dublin homes.

Loft roll insulation, also known as blanket insulation, is made from mineral wool or glass fibre. 

It comes in large rolls or batts, making it easy to install. Its flexible nature allows for seamless fitting between attic joists, ensuring a snug and uniform thermal barrier that prevents heat transfer and temperature fluctuations.

Types of Loft Roll Insulation

Loft roll insulation comes in various materials and compositions to meet your specific insulation needs. The most common types include: 

Mineral Wool Insulation 

Mineral wool loft roll insulation is made from natural minerals like basalt, rock, or slag. The fibres are spun and formed into flexible rolls or batts. 

Mineral wool insulation offers superb thermal performance, sound absorption, and fire resistance. It’s made from sustainable and recyclable materials, making it an eco-friendly solution for your home. 

Glass Fibre Insulation 

Glass fibre loft roll insulation is made from recycled glass and sand. The fibres are spun into rolls or batts, creating a lightweight and cost-effective insulation solution. Glass fibre insulation offers good thermal resistance and is widely used in attics for its affordability and ease of installation.

  • Fire Resistance: Most loft roll insulation materials are designed to be fire-resistant, adding an extra layer of safety to your home and providing valuable evacuation time in case of a fire.

Other Types of Attic Insulations

While loft roll insulation is a popular and effective choice for many attics, it may not necessarily be the best option for every situation. Apart from loft roll, here are some other attic insulation options worth considering:

Rigid Foam Board Insulation

Rigid foam board insulation is made from polystyrene, polyurethane, or polyisocyanurate foam, which is manufactured into rigid boards or panels. It’s known for its high thermal resistance and ability to create a continuous and robust barrier against heat transfer.

There are three common types of rigid foam board insulation used in attics: Expanded Polystyrene (EPS), Extruded Polystyrene (XPS), and Polyisocyanurate (Polyiso).

EPS is made from expanded polystyrene beads. It’s suitable for various applications, including roof decks and walls.

XPS insulation is denser and more moisture-resistant than EPS. It’s commonly used in areas prone to moisture exposure, such as flat roofs and below-grade applications.

Polyiso foam has the highest R-value per inch among rigid foam insulation types. Because of this, it’s a popular choice for maximizing thermal efficiency in attic spaces.

Advantages of Rigid Foam Board Insulation 

  • Impressive Thermal Resistance: Rigid foam insulation offers some of the highest R-values available among insulation materials. It effectively reduces heat conduction, providing high levels of thermal insulation for your home.
  • Space-Saving: The rigid boards are thin yet highly effective, making them ideal for attics with limited space. They provide optimal insulation without taking up much headroom.
  • Moisture Resistance: Rigid foam board insulation is inherently resistant to moisture, making it a great choice for areas prone to high humidity or potential water exposure.
  • Durable and Long-Lasting: Once installed, rigid foam insulation maintains its structural integrity without sagging or settling over time. It remains effective for the life of your home, requiring little to no maintenance.

How Much Attic Insulation Do You Need? Finding the Optimal Level for Comfort and Efficiency

The appropriate attic insulation level depends on several factors, such as the climate in your area, the type of insulation used, and local building codes.

R-Value 

The effectiveness of attic insulation is measured by its R-value, which indicates its thermal resistance. The higher the R-value, the better the insulation’s ability to resist heat transfer. 

Different regions have different recommended R-values based on climate conditions. In Dublin, the recommended R-value for attic insulation falls within the range of R-38 to R-60.

Existing Insulation Levels

Before adding more insulation, you must assess the existing level of insulation the attic has. 

If your home was built before, say, the 1980s, it’s possible that it has insufficient insulation and requires a top-to-down upgrade.

But if your attic already has some insulation, you can determine the additional amount required to reach the recommended R-value with the help of a contractor.

Insulation Type and Application

The type of insulation you choose, such as loft roll, blown-fibre, spray foam, or rigid foam board, will impact the required amount to achieve the desired R-value. 

Each type has different thermal properties and installation methods, affecting the thickness needed to reach the recommended R-value.
