To seal an attic so that conditioned air cannot pass through the top plate or any other penetrations is a big job. But it truly must be done! Without air-sealing your attic, the insulation you put in place is just an air filter. Knauf produces a blue latex sealant that is eco-friendly and speeds up the process of covering the entire attic for a professional air-seal. Great way to protect your home - keeping good air in and bad air out.
