Insulation & Ventilation
Sample Building Supply stocks many types of insulation: fiberglass batt, rigid foam panel, mineral wool, weatherization wrap, and attic insulation baffles. In addition, we carry vents for foundations, roofs, soffits, gables, cornices, and louvers. Our experienced staff can advise you on which insulation and venting products will work best for you.


Fiberglass Batt Insulation by Johns Manville
There are a number of insulation choices for every part of your home—each with different advantages and benefits. Johns Manville home insulation products offer you superior quality and safety to help improve the energy efficiency and comfort of your home. Regardless of where you start insulating (attic, basement, etc.), JM has insulation choices to match your needs and budget.


Rigid Foam Panel Insulation by Dow Blue Styrofoam
This extruded polystyrene foam residing board from Dow helps enhance energy efficiency and reduce condensation. Designed for residential and commercial applications, Styrofoam™ Brand Square Edge Insulation has long-term thermal performance and helps protect foundation damp-proofing and waterproofing, especially during backfilling. The square edges help ensure energy efficiency and minimize on-site cutting and waste.


Mineral Wool by Johns Manville
There are a number of insulation choices for every part of your home—each with different advantages and benefits. Specifically designed to deliver robust sound dampening, exceptional fire resistance and superior temperature control, Mineral Wool is most commonly installed in wood-stud cavities of interior and exterior walls, basements, ceilings, floors and crawl spaces.


Vapor Barrier by Tyvek
Dupont™ Tyvek® weatherization wrap increases air and water resistance, helps lower heating and cooling costs, and provides protection against water and moisture intrusion. The unique qualities of Tyvek® help stop airflow through wall cavities, help hold out bulk water and wind-driven rain, and allow moisture vapor to escape from inside walls. The result is a more comfortable, energy-efficient building with far fewer chances for damage from degradation effects.


Lomanco Foundation Vent
Lomanco® foundation vents are used to keep crawl spaces dry and allow light to enter. Available in plastic, die-cast aluminum, and all-aluminum construction, they come in several different styles—shutter style, hinged louver style, and with a damper for tight closure. They are designed with an 8x8 perma-coated aluminum screen attached and are engineered for maximum venting capacity.


Attic Insulation Baffles
Baffles provide a channel for air to flow from the soffit through the attic. Proper air circulation in the attic helps prevent moisture buildup. Baffles are sometime called rafter vents, insulation baffles, vent chutes or proper vents. They are inexpensive, easy to install, and are a very effective home energy saving project.


Lomancool Power Roof Vent
Lomanco® Standard Power Vents are designed for quiet operation and high volume air removal. Lomanco offers two styles of electric power vents- the Lomancool™ 2000 and the Add-A-Vent 1800. The 2000 is a roof mount power vent and the 1800 is designed to be mounted behind an existing vent to add powered ventilation to a gable.

Continuous Soffit Vents
Continuous soffit vents are installed in the eave or soffit to offer free air movement into soffits and dead air areas. They are usually made of aluminum or PVC and continue the length of the soffit.


Cornice Vents
Cornice Vents are installed in the eave or soffit to offer free air movement into soffits and dead air areas. They are located between the rafters. One square foot of vent is calculated per each 150 square feet of attic space.
