Isoboard Thermal Ceiling Insulation Properties

Isoboard ceilings are known for their exceptional thermal insulation. As a result, the 50mm Isoboard Ceiling has an impressive R-value, which means it’s excellent at resisting heat flow. Because of its R-value, it helps keep your home cooler in summer and warmer in winter, allowing you to enjoy a more comfortable living space year-round.

The high-density structure of Isoboard (32-36 Kg/m3) ensures excellent thermal insulation, which translates to practical, long-term energy savings. By reducing heat transfer, these ceilings can help lower utility costs significantly. The 50mm Isoboard Ceiling, followed by the 40mm Isoboard Ceiling, has the most Thermal Insulation properties. Even though the 30mm Isoboard Ceiling lags behind the two primary Isoboard sizes, it is famous as it is still regarded as a Thermal Ceiling.

Moisture Resistance of Isoboard Ceiling Boards

One of the standout features of Isoboard Ceiling Boards is their impressive water resistance. They absorb less than 1% water by volume, meaning they’re not affected by water leaks, making them ideal for use in bathrooms, kitchens, and indoor swimming pools.

If your roof leaks, you won’t need to worry. 50mm Isoboard Ceiling won’t absorb water, maintaining its integrity and performance. This moisture resistance also helps prevent mould and bacteria growth, ensuring a healthier living environment.

Isoboard Ceiling Fire Safety Ratings

Safety is a top priority, and Isoboard ceilings don’t disappoint. They have a B/B 1/2 fire rating and won’t sustain a flame. While not fireproof, they contain flame-retardant gases that cause the board to self-extinguish.

In the event of a fire in the roof space, the Isoboard won’t support the flame. We can install Aerolite Insulation with a class AA 1/1 fire rating for added peace of mind. This combination provides an even more robust fire-resistant barrier.

The Esthetic Appeal of Isoboard Ceiling Boards

Isoboard ceilings aren’t just functional; they’re also visually appealing. They feature a smooth, white surface that’s paintable, allowing you to customize the look to match your interior design. The tongue-and-groove finish adds a touch of elegance to any room.

These ceilings create a seamless, sophisticated look that complements modern and traditional interiors. Plus, they’re easy to clean with water and mild detergent when necessary, so you can maintain their pristine appearance with minimal effort.

In conclusion, Isoboard ceilings offer a perfect blend of functionality and style. They provide superior thermal insulation, excellent moisture resistance, and enhanced fire safety. All while adding a touch of elegance to your living spaces. No wonder they’re becoming increasingly popular among homeowners and builders looking for energy-efficient, durable, and attractive ceiling solutions.

Comparing an Isoboard Ceiling Boards to Other Ceiling Options

Traditional vs. Isoboard ceiling

We’ve seen a significant shift in ceiling options over the years. Traditional ceilings, like Rhinoboard, have been around for a long time. They’re usually 6mm or 9.5mm thick and require skimming of all joints. While these ceilings are dense. Unfortunately, XPS does not have an excellent Noise Reduction Coefficient. As a result, we would install a 135mm Knauf Insulation or a 135mm Aerolite Insulation product with a high NRC. Significantly, these two options also increase the home’s R-value, resulting in a far more relaxed home in summer and warmer winter.

Installing traditional ceilings is labour-intensive and messy. The process creates dust and can be unpleasant in existing homes. It also takes several days to complete, including skimming and painting. Most importantly, traditional ceilings offer no thermal insulation value.

In contrast, Isoboard ceilings are a game-changer. They’re available in thicknesses from 25mm to 50mm and offer excellent thermal properties. The installation is clean and dust-free and doesn’t require skimming or painting so that we can complete the job much faster than traditional options.

Isoboard is also highly resistant to water damage. Unlike conventional ceilings that roof leaks or broken pipes can ruin, Isoboard doesn’t absorb water. This durability means you won’t need to replace your ceiling every 20 years, as is often the case with traditional options.

Isoboard vs. other insulation materials

Regarding insulation, Isoboard Thermal Ceilings stand out from the crowd. Their rigid XPS structure gives them strength and thermal abilities. This design gives Them a high compressive strength and excellent resistance to moisture transfer.

Isoboard works as an insulator because of the gas trapped within its cells. These cells have very low thermal conductivity, and the cell walls prevent heat transfer through convection. The thicker the board, the better its thermal resistance.

However, it’s worth noting that Isoboard alone may not provide sufficient thermal insulation for your entire home. We often combine it with other insulation materials. For instance, adding Soft Touch Aerolite or Knauf Insulation above the Isoboard ceiling can enhance thermal insulation and noise reduction.

Isoboard Ceiling Boards Cost-benefit analysis

While the initial cost of Isoboard might be higher than traditional options, the long-term benefits are substantial. Homes insulated with Isoboard typically recover the cost through energy savings within two to three years. This quick return on investment is due to the significant reduction in heating and cooling costs.

Isoboard’s versatility adds to its value. It can be used for ceilings, wall cavities, and underfloor insulation. In wall cavities, 30mm or 40mm Isoboard panels can substantially reduce heat buildup. For underfloor applications, 40mm or 50mm Isoboard Ceiling Boards can improve heating efficiency, especially in homes with underfloor heating systems.

The durability of Isoboard is also a factor in its cost-effectiveness. Unlike traditional ceilings that may need replacement after 20 years, Isoboard is built to last. Its resistance to moisture and ability to maintain its insulating properties over time make it a sound long-term investment.

In conclusion, while Isoboard may have a higher upfront cost, its energy efficiency, durability, and versatility make it a cost-effective choice in the long run. Its comfort and energy savings can significantly enhance your home’s livability and value.

Choosing the Right Isoboard Ceiling Boards

Several factors must be considered when selecting the perfect Isoboard ceiling for your home. Let’s explore the key aspects to help you make an informed decision.

Thickness options and R-values

Isoboard ceilings come in various thicknesses, ranging from 25mm to 80mm. The thickness you choose directly impacts the thermal resistance, or R-value, of your ceiling. Here’s a breakdown:

• 30mm Isoboard Ceiling: R-value of 1.143
• 40mm Isoboard Ceiling: R-value of 1.524
• 50mm Isoboard Ceiling: R-value of 1.905

The thicker the board, the higher the R-value, which means better insulation. However, doubling the thickness doesn’t halve the temperature. For instance, a 25mm board might result in a 29°C surface temperature on a hot day, while a 50mm board could lower it to 25°C.

We recommend using the “long-term design” value for R-value calculations. This ensures that your ceiling will meet thermal performance standards throughout its lifespan.

Isoboard Size and Coverage Considerations

Isoboard ceiling panels come in standard lengths from 1.8m to 8.0m, with 0.6m increments. We also offer 8m boards for larger spaces. The width is consistently 600mm (± 2mm) for all boards.

When planning your installation, keep these dimensions in mind:

1. Measure your room carefully.
2. Calculate the number of boards needed based on the room size.
3. Consider the length options to minimize waste.

The tongue-and-groove edge profile allows for easy interlocking of adjacent boards, ensuring a seamless finish.

Isoboard Ceilings Colour and finish selections

Isoboard ceilings offer versatility in terms of appearance. Here are your options:

1. Natural white: The board’s natural colour is white, often eliminating the need for painting.
2. Painted finish: You can paint Isoboard with water-based paints for a custom look.
3. IsoPine finish: This option mimics a tongue-and-groove pine surface, with grooves at 100mm centres along the board’s length.
4. The bevelled edge creates a panelled look, adding depth to your ceiling.

When choosing a finish, consider your room’s overall design and the aesthetic you want to achieve. Remember, Isoboard is easy to clean with water and mild detergent, maintaining its appearance over time.

By carefully considering these factors – thickness and R-value, size and coverage, and colour and finish – you’ll be well-equipped to choose the right Isoboard ceiling for your home. This decision will impact not only your home’s energy efficiency but also its overall look and feel.
