  • Quick and easy to install, no special tools required.

HT HORIZONTAL TRAYS

Installed at the interface where an external wall becomes an internal wall below a roof line e.g. top edge / lean too roof abutments, flat roof abutments and for masonry built off structural ring beams.

  • Integral water discharge channel.
  • 2½ brick length designed for ease of sequential installation in existing masonry construction.
  • Self supporting - no need to tie into inner leaf.
  • Weather protection lip.
  • Preformed corners and stopends.
  • Available with or without integral, factory fitted Aluflash or lead cover flashings.
  • Glidevale recommend the use of Aluflash, an environmentally friendly alternative to lead as a weathering flashing material.

AT INTRA WEEP ABUTMENT TRAYS

A comprehensive range of cavity trays designed for use in brick, block or random stone external masonry walls.

Installed at the junction where the sloping edge of a pitched roof abuts a wall i.e. where the external wall becomes an internal wall below the roofline.

NHBC Standards and BS 8215 specifically recommend the use of preformed abutment cavity trays for this application.

  • Integral roof pitch markings on brickwork trays.
  • Integral weepholes to promote active drainage.
  • Self supporting cavity upstand avoids the need for the tray to be built into the internal masonry wall.
  • Fleximouth Mortar Barrier on brickwork trays provides a clear void for fitting separate roof flashings without the use of masonry saws.
  • Corner catchment set for return abutment detailing, reduces the visual impact of the return cover flashing
  • Available with or without pitch dedicated, factory fitted Aluflash or lead flashings.

AT BLOCKWORK ABUTMENT TRAYS

A comprehensive range of cavity trays designed for use in block or random coursed stone external masonry walls.

Installed at the junction where the sloping edge of a pitched roof abuts a wall i.e. where the external wall becomes an internal wall below the roofline.
NHBC Standards and BS 8215 specifically recommend the use of preformed abutment cavity trays for this application.

  • Course heights of 225mm and 150mm as standard, other course heights are available to order.
  • AT100 vertical connector.
  • Catchment starter trays incorporate a single MV650 weephole.

MCR MULTI-CREASE ROLL

A robust, damage resistant cavity tray “on a roll” which utilises factory applied continuous creases to enable the tray to folded to suit a variety of applications. Unlike other flexible roll form cavity trays, Glidevale MCR multi-crease roll has the added benefit of being self supporting in the cavity.

  • Ideal for use at ground level as a continuous cavity tray or in parapet applications.
  • Can be used over proprietary lintels.
  • Can be folded to form a continuous cavity barrier for ground gas protection strategies
  • 25m roll reduces on site jointing.
  • 0.75 or 1.0m thick resists accidental damage on site.
  • Full range of pre-formed, factory fabricated corners steps and stop ends available.

ASG ABUTMENT SECRET GUTTER

For use where the sloping edge of a flat interlocking tiled roof abuts a wall.

The ASG overcomes the potential for water penetration by capillary action between the underside of the lead cover flashing and the top of the flat roof tile.

Can be used with profiled roof tiles for greater weather resistance in areas of high exposure.

  • Manufactured from GRP - has little or no theft value on site.
  • AB fire rating to BS476 pt3
  • Positive 25mm upstand.
