Part of this Leesburg VA attic project included building a new service deck to allow access to the HVAC unit in the attic. This will help to keep the insulation contained and let the service technician freely walk to and from the HVAC unit.
Metal (and brick) flue pipes and chimneys can get very hot when furnaces, water heaters, and fireplaces vent through them. Insulation should not touch these assemblies due to the possibility of fire in the attic of the home. Comfenergy wraps these flues and chimneys with rock wool fire resistant insualtion before blowing new TruSoft cellulose insulation into your attic.
The old insulation in this Herndon VA attic was thin and dirty after years of working like a filter to the uncontrolled air moving in and out of the attic. Dust and allergens collected in the insulation created dark spots and the open vent slits in the wall allowed it to happen for years. Our production crew removed the old insulation, used Zyp Foam to air seal the space and added new soffit baffles along the bottom of the roof line. Afterwards, the rest of the attic would be filled with Tru Soft blown in cellulose insulation.
An uninsulated cantilever can lead to cold floors in a home. In a home with a cantilever, the rooms inside can react to outdoor temperatures when air is able to freely pass in and out of the cantilever, resulting in cold during the winter and heat during the summer. This type of comfort issue can result in higher than needed electric bills if the homeowner is relying on their HVAC unit to solve the problem but turning the heat up or the AC down. Dense packing the cantilever happens by cutting access holes and packing them with insulation.
These before and after pics show what an empty attic looks like with new soffit air baffles installed.....just waiting on fresh, new TruSoft cellulose.
