Cavity Socks 91 - 100mm 1200mm (Orange)

The Dacatie fire sock is an advanced insulation solution specifically engineered to improve fire resistance in cavity spaces. Designed for cavity widths of 91-100mm and with a length of 1200mm, this product features a one-hour fire-resistant insulation layer, making it suitable for both masonry/blockwork and masonry/timber frame systems. It is constructed from Knauf ECOSE Mineral Wool encapsulated in recycled plastic, ensuring it does not contribute to fire propagation while providing up to four hours of fire integrity.

Ideal for trade professionals and DIY enthusiasts alike, the Dacatie fire sock effectively prevents the spread of flames, smoke, and sound along cavities. Its thermal conductivity is rated at 0.037W/mK, and it can be installed vertically or horizontally, complying with Robust Detail Part E and meeting the building regulations outlined in Approved Document B (fire) and Document E (acoustics). The installation is straightforward, allowing for compression fit or attachment using staples/nails at 150mm centres in timber frame applications.
