Insulation4Us is proud to feature a comprehensive selection of Cavity Wall Insulation products that adhere to the highest standards of quality and efficiency, mainly from the reputable manufacturer, Owens Corning, and other esteemed vendors such as Rockwool, R-Max, Hunter Panels, Knauf, and Kingspan.

Fiberglass Insulation Batts from Owens Corning

In this category, a broad spectrum of Owens Corning Fiberglass Insulation Batts is available, coming in varied R-values (R-8 to R-49) and sizes. These are essential for imparting optimal thermal and acoustic insulation within walls, ceilings, and floors across residential and commercial structures.

Usage:

Ideal for efficient energy management and temperature moderation while effectively reducing sound transmission between rooms or units.

Guidance:

Selection should align with regional climatic conditions and local building codes, with higher R-values like R-49 recommended for colder climates and moderate R-values such as R-19 suitable for milder climates.

Rockwool Mineral Wool Insulation

The Rockwool Mineral Wool CavityRock is a prominent inclusion, revered for its thermal insulation and fire-resisting properties. Available in 16" x 48" and 24" x 48" dimensions, it suits exterior cavity wall applications.

Usage:

It’s particularly favored in locations demanding noise reduction due to its sound-absorbing attributes.

Guidance:

Choose according to the cavity wall dimensions and consider the density for specific thermal or acoustic needs.

XPS Insulation Boards

Our array of Extruded Polystyrene (XPS) Insulation Boards from Owens Corning and Kingspan are recognized for their exceptional moisture resistance and high R-values, providing versatile solutions for diverse insulation needs.

Usage:

These are ideal for insulating basements, foundations, and above-grade exterior walls, thanks to their capability to resist water and moisture.

Guidance:

Selection should consider the required R-value and board thickness, with a focus on higher R-values for superior thermal resistance.

Polyiso Panels

The Hunter Panels Xci Foil Polyiso Panel is another significant offering in this category, notable for its high R-value and versatile application.

Usage:

These panels are highly efficient for thermal insulation in walls, ceilings, and roofs, serving both residential and commercial buildings.

Guidance:

While choosing polyiso panels, consider the thickness and size that would be the most effective for the project’s insulation requirements.
