Touch ‘n Foam offers a number of products for air sealing various areas of a typical attic. Our 2-component spray foam kits are ideal for air sealing large areas like attic floors and walls. Ready-to-use sealants and gun foams are ideal for sealing hatches, soffits, large gaps and HVAC, electrical and plumbing penetrations.
Floor / Wall Junctures
Air infiltration along the top wall plate at edge of the attic causes heating/cooling loss and adds energy expense.
Spray foam sealant to cover edges of wall plate where it meets attic floor and joists to stop air infiltration, block pests and reduce energy costs.
Attic hatch doors are a common point of heat/cooling loss, causing higher energy bills.
Remove loose insulation. Spray a bead of foam sealant or gun foam to fill perimeter gap. Let cure before closing door. Spray foam on out sides of attic hatch assembly to seal exposed seams with studs and joists.
HVAC / Electrical Penetrations
Heating and air conditioning ducts in attics penetrate living areas, creating gaps around duct boots and grill plates that result in unwanted air infiltration.
Spray foam sealant around HVAC boots where they penetrate the drywall below. Also, spray foam where flexible ducts connect to the penetrating boot.
The 2-component polyurethane spray foam kits provide thermal air sealing and sound attenuating benefits and are low pressure, permanent and dry within minutes of application.
