When it comes to ensuring the optimal thermal performance of a loft or attic space, selecting the most efficient, high-quality loft blanket insulation is paramount. In this category, you will discover a range of loft blanket insulation products, each offering their own specialities in terms of thermal, acoustic, and fire performance.

Knauf Insulation

Knauf presents a broad spectrum of insulation rolls and slabs suitable for varied applications. Products like "Knauf Loft Roll 44" and "Knauf OmniFit Roll" offer combi-cut solutions, aiding in easy installation across irregular or specific loft spaces. The brand is also notable for acoustic solutions ("Knauf Acoustic Roll") and diverse density options, such as the RS series (e.g., "Knauf RS45", "Knauf RS60"), allowing customers to select products that meet specific thermal and acoustic demands.

Rockwool Insulation

Rockwool products are distinguished for their stellar thermal, acoustic, and fire performance properties. For instance, "Rockwool RWA45" and "Rockwool RW5" come in various sizes to meet different insulation thickness requirements. "Rockwool RW3" stands out for providing an all-encompassing solution, encapsulating acoustic, thermal, and fire performance in one product, catering to those who seek multi-faceted insulation solutions.

Sheepwool Insulation

100% Sheepwool Insulation Comfort Roll offers a natural, breathable, and sustainable insulation solution for those who are environmentally conscious. Sheepwool insulation not only provides excellent thermal performance but also manages moisture efficiently, ensuring a comfortable and dry interior environment.

Isover

Isover provides quality loft insulation solutions like "Isover Spacesaver Combi-Cut", known for their reliable thermal performance and easy installation due to their combi-cut design, making them an ideal choice for DIY installers and professionals alike.

Actis Insulation

Actis offers technologically advanced insulation products like "Actis Hybris" and "Eolis HC", renowned for their reflective properties and impressive thermal performance. These products are especially suited for those seeking innovative, space-saving insulation solutions that don’t compromise on efficiency.

Thermafleece

Thermafleece presents insulation rolls such as "Thermafleece SupaSoft Roll" and "Thermafleece CosyWool Roll" that stand out for their sustainable and eco-friendly properties. Crafted from recycled plastic bottles (SupaSoft) and natural wool (CosyWool), these products provide a greener option without sacrificing insulation effectiveness.

How to Choose the Right Product?

When navigating through the abundant choices in loft blanket insulation, consider the following aspects:

  • Thermal Performance: Select a product that aligns with the desired U-value and complies with building regulations.

  • Acoustic Properties: If sound insulation is paramount, opt for products renowned for their acoustic dampening properties, like specific Knauf and Rockwool products.

  • Sustainability: For eco-conscious projects, explore products like Sheepwool and Thermafleece, which offer effective insulation while prioritising environmental sustainability.

  • Space Considerations: Consider the available space for insulation and choose a product that aligns with the physical constraints of the loft area.

  • Budget: While prices may vary, consider products that offer a balance between cost and effective, long-lasting performance.
