MortarNet™ with Insect Barrier™ - the original mortar dropping collection device

September 30, 2022

Nearly 25 years in the industry. Over 100 Million feet installed. Not a single wall failure.

In masonry cavity walls, mortar collection above the flashing and weep hole levels is vital for proper masonry cavity wall performance and to prevent water damage. In today’s walls, it’s common to see a 2” cavity reduced to the minimum requirement of 1” with the inclusion of insulation, so the need for better ventilation is essential to keep the wall dry and trouble-free. MortarNet™ with Insect Barrier™ suspends mortar droppings above the flashing and weeps, so they stay clear and unobstructed. The patented Insect Barrier helps deter insects from entering the cavity through the weep holes. Its NEW design using a structural strand polymer mesh allows moisture to flow to the weeps and significantly greater airflow within the cavity to promote drying.

Features

Dual levels
Trapezoidal shape
Structural strand polymer mesh
Patented Insect Barrier
Made from 40% post-consumer recycled content

Benefits

Compressible to allow for variations in cavity width
Breaks up and suspends mortar droppings above the flashing on two levels so weeps stay open
Open weave mesh construction provides hundreds of pathways for moisture to exit the cavity
Insect Barrier helps prevent wall damage and health hazards from insect infestations
Is very permeable to air, water and water vapor due to the low fiber density of the non-woven structure
Helps prevent efflorescence and damage from freeze-thaw cycles
Easy to transport, handle and cut, even on scaffolding
Installs easily on brick ties in multi-story cavity walls
Will not degrade, oxidize or react with common building materials
Recycled content helps with LEED certification
Helps eliminate callbacks to repair moisture damage
Provides masons and building owners with greater peace of mind
