  Subscribe to FREE newsletter  Jul 26, 2023

The mortar-dropping collection device that brings the industry-leading moisture protection of MortarNet® with Insect Barrier™ to residential construction.

In residential 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. HouseNet suspends mortar droppings above the flashing and weeps so they stay clear and unobstructed.

Its 90% open mesh allows moisture to flow to the weeps and air to move within the cavity to promote drying. By using HouseNet for mortar suspension and collection, residential cavity walls perform the way they're designed and walls stay fry and trouble-free.

  • Made from 33% pre-consumer, 17% post-consumer recycled content


  • Smaller size and lower price than commercial MortarNet make it ideal for quality residential construction

  • Open weave mesh construction provides hundreds of pathways for moisture to exit the cavity

  • Provides masons and building owners with greater peace of mind

Weep holes must be used with HouseNet to allow effective moisture drainage and wall drying. Click on WeepVent or CellVent to see how they can help keep weep holes open and prevent insects from entering the cavity through the weeps.
