FAQs

What is the U-value of 100mm Kingspan? The U-value of 100mm Kingspan insulation typically ranges from 0.18 to 0.22 W/m²K.

How do you get the 0.18 U-value wall? To achieve a U-value of 0.18 for a wall, you typically need sufficient insulation, well-fitted insulation boards like Kingspan or Celotex, and effective sealing of any gaps or joints.

What is the U-value of 0.16 W/m²K? A U-value of 0.16 W/m²K indicates highly efficient insulation, suitable for achieving excellent thermal performance in buildings.

How do you calculate the U-value of insulation? The U-value of insulation is calculated by considering the thermal conductivity of the material and its thickness, along with any additional layers and their respective U-values.

Why is Kingspan more expensive than Celotex? Kingspan may be more expensive than Celotex due to differences in manufacturing processes, material quality, brand reputation, and market demand.

What is the U-value of 120mm Celotex? The U-value of 120mm Celotex insulation typically ranges from 0.16 to 0.20 W/m²K.

Can I still build with 100mm cavity? Yes, building with a 100mm cavity is still feasible, but it’s important to ensure proper insulation and compliance with building regulations to achieve desired thermal performance.

What is the U-value of 100mm exterior wall insulation? The U-value of 100mm exterior wall insulation generally falls between 0.15 to 0.20 W/m²K, depending on the specific type and quality of insulation used.

What is the current U-value for walls in the UK? The current recommended U-value for walls in the UK typically ranges from 0.18 to 0.30 W/m²K, depending on the type of construction and insulation.

Is a U-value of 1.4 good? A U-value of 1.4 is acceptable but not particularly good. Lower values indicate better insulation performance.

Is 1.0 a good U-value? Yes, a U-value of 1.0 is considered good, indicating effective insulation that meets or exceeds standard building regulations.

Is 0.8 a good U-value? Yes, a U-value of 0.8 is very good, indicating high-performance insulation that exceeds typical building regulations.

What is the minimum U-value for walls? The minimum U-value for walls in building regulations typically ranges from 0.18 to 0.30 W/m²K, depending on factors such as construction type and location.

What is the U-value of 270mm insulation? The U-value of 270mm insulation generally ranges from 0.10 to 0.16 W/m²K, depending on the specific material and quality.

Is the higher the U-value the better the insulation? No, the lower the U-value, the better the insulation. A lower U-value indicates that less heat is transmitted through the material, resulting in better thermal insulation.

What is the issue with Kingspan? Kingspan has faced scrutiny and criticism over issues such as environmental concerns related to manufacturing processes and product performance claims.

Do I need a Vapour barrier with Kingspan? It depends on the specific application and building requirements, but in many cases, a vapor barrier is recommended with insulation to prevent moisture-related issues.

Which is better Celotex or Kingspan? The choice between Celotex and Kingspan depends on factors such as specific project requirements, budget, availability, and personal preference. Both are reputable brands offering high-quality insulation solutions.

What is the thermal value of 100mm Celotex? The thermal value of 100mm Celotex insulation typically ranges from 0.022 to 0.026 W/mK.

What is the best U-value for Celotex? The best U-value achievable with Celotex insulation depends on the thickness and application, but generally, lower U-values indicate better performance.

What is the U-value of 60mm Celotex? The U-value of 60mm Celotex insulation typically ranges from 0.22 to 0.26 W/m²K.

What thickness of Kingspan should I use? The appropriate thickness of Kingspan insulation depends on factors such as desired U-value, building regulations, and specific project requirements. Consultation with a building professional is recommended to determine the optimal thickness.

What are the new insulation rules in the UK? As of my last update, specific new insulation rules may vary, but generally, there is a focus on improving energy efficiency and reducing carbon emissions through stricter building regulations and incentives for better insulation.

Can you insulate a 50mm cavity? Yes, it is possible to insulate a 50mm cavity, but achieving desired thermal performance may require higher-performance insulation materials.

What is the U-value of Celotex by thickness? The U-value of Celotex varies by thickness, with thicker insulation generally offering lower U-values. Specific values should be checked based on the product specifications and application.

What is the lowest U-value of cavity wall insulation? The lowest achievable U-value for cavity wall insulation depends on factors such as insulation material, thickness, and installation quality but can typically range from 0.15 to 0.30 W/m²K.

What is the R value of 100mm insulation board? The R-value of 100mm insulation board typically ranges from 4.0 to 5.0 m²K/W, depending on the specific material and density.

What is the U-value of plasterboard? The U-value of plasterboard alone is relatively low since it serves primarily as a finishing material rather than insulation. However, when used in conjunction with insulation, it contributes to the overall thermal performance of a wall.

What is the U-value of brickwork? The U-value of brickwork alone is relatively high, typically ranging from 1.0 to 2.0 W/m²K, depending on factors such as thickness and type of bricks.

What is the U-value of insulated plasterboard? The U-value of insulated plasterboard depends on factors such as the thickness of insulation and the type of plasterboard used, but it typically ranges from 0.15 to 0.30 W/m²K.

These values are estimates and may vary depending on specific materials, applications, and regional regulations. It’s important to consult with building professionals and refer to product specifications for precise information.
