The comfort level of a home is determined by radiant surface temperatures. It is extremely important that no ceiling, wall or floor surface is cold. High room temperatures will not overcome the drafty feel of a room with cold walls.

Comfort tips

• Thermal bypass (the ability of cold air to go through or around insulation) should be completely eliminated by proper blocking in in framing details before insulating. 
• All penetrations in exterior and interior skins are fully air sealed. 
• All voids at wall junctions,  corners and headers should be drilled and blown full of insulation.
• Give special thermal bypass attention to every break in plane throughout the structure- wall/ceiling junctions, drop soffits, built in bancos, fireplaces, nichos, parapets.
• Two story homes need special thermal bypass attention at the band joist at floor edges.
