Installing Recticel Eurowall Cavity Plus

General guide
  • The correct wall tie type should be selected for the type of building under construction. Wall tie manufacturers should be consulted for further advice regarding suitablity.
  • Recticel Eurowall Cavity Plus insulation boards should be installed against the inner leaf, secured with universal retaining clips.
  • The internal leaf is constructed ahead of the external leaf. Any mortar protruding into the cavity airspace from the back of the internal leaf should be cleaned off before installing the product.
  • It is recommended that an additional wall tie is included within 225mm of openings on each board course level to satisfy the structural requirements of the wall.
  • Walls are constructed with the first row of wall ties where the insulation is to begin, but not directly on the DPC, and at approximately 600mm horizontal centres. The first row of boards can start below the DPC to allow at least a 150mm overlap with the floor insulation.
  • A section of the wall leaf is built up to a course above the next row of wall ties, which are placed at 450mm vertically and 900mm horizontally. Insulation boards are placed between two rows of wall ties with the tongue and groove joints tightly interlocked and vertical joints staggered. Slots should be cut with a sharp knife or fine toothed saw into the insulation boards to allow wall ties to fit snuggly between board joints, sloping down to the outer leaf.
  • Upon completion of each section, excess mortar should be removed and mortar droppings cleaned from exposed board edges before installation of the next section. Use of a cavity board is recommended to make cleaning easier.
  • To fit around any opening, doors or windows, boards should be cut carefully and accurately to completely fill the spaces for which they are intended, ensuring continuous insulation throughout the wall.
  • Where multiple openings are in close proximity, it is recommended that a continuous lintel or cavity tray is used. Damp proofing at lintel level must be provided with stop ends and weepholes.
  • Where required, door and window reveals must incorporate cavity closure depending on the set-back of the frame.
  • Corner details are formed by cutting the boards squarely and closely butt-jointing, or by cutting board ends at a 45º angle to create a mitred joint, so that all board interfaces are uninterrupted. All corner details incorporate a vertical 300mm wide DPC or a proprietary tape.
  • At the end of each day’s work, or during any interruption in construction, the exposed unfinished cavity should be covered to protect it from poor weather.
