Rigid Insulation With Rainscreen Over Concrete Wall

Current pneumatic nailers have maximum fastener lengths.

Rigid insulation with rainscreen over concrete wall.

Any of the following insulation materials are acceptable for this purpose. This refers to insulation uninterrupted by furring or by the webs of concrete masonry units. Rockwool insulation within the exterior wall stud cavity and the external cavity offers superior long term thermal efficiency fire resistance moisture control and acoustic performance. With a minimum of 70 recycled content the installed thermafiber products contributed to valuable leed credits helping the building earn a leed platinum certification.

We re proud to say our products can be found in some of the tallest and safest buildings around the globe like salesforce tower. There are several ways to install subflooring above the rigid foam. The best way to insulate the interior side of a basement wall is with foam insulation that is adhered to or sprayed directly on the concrete. Examples include rigid insulation adhered to the interior of the wall with furring and drywall applied over the insulation continuous insulation in a masonry cavity wall and exterior insulation and finish systems.

For example mineral wool boards are typically installed over the primary wrb layer and add an additional drainage surface behind the cladding as well as a non combustible insulation layer. The high density outer layer offers greater rigidity and water repellence while the inner layer helps to conform to architectural features. Case study salesforce tower. Minimum nail length must accommodate sheathing and penetrate framing a minimum 1 inches.

Mineral wool boards foam sheathing and closed cell spray foam can all work as ci in a rainscreen system. Rockwool semi rigid stone wool insulation is engineered with dual density technology with a high density outer layer and a lower density inner layer. Rigid foam can be adhered to a poured. You can use either one or two layers of plywood or osb and the subflooring can either be fastened to the concrete with long tapcon screws or it can simply float above the foam.

One of the options the iecc prescriptive r values iecc table 502 2 1 calls for continuous insulation on concrete masonry and other mass walls. Our rainscreen and cavity wall insulation within the exterior wall stud cavity and the external cavity offers superior long term thermal efficiency fire resistance moisture control and acoustic performance. If your basement slab lacks sub slab foam you ll have to install the insulation above the slab. Closed cell spray polyurethane foam or either xps eps or polyisocyanurate rigid foam.

And there is no effective way to fill the voids in an existing concrete block wall. Rainscreen cavity wall insulation.
