The introduction of the roof truss saved a lot of construction time and costs and eliminated or reduced the need for support posts. Unfortunately, the truss creates a cold climate issue called uplift. When it is part of an insulated attic, the top “chords” stay cold while the bottom ones remain warmer due to insulation […]
Read moreCondensation brings us back to the breathability discussion. Adding insulation over the walls and roof makes a continuous thermal barrier while burning the thermal bridges. However, when adding or wrapping more insulation, make sure that air, water, and thermal barriers are working together and not against. Trapped moisture in a tight building envelope equals mold, […]
Read moreTraditional structures were designed to allow moisture to evaporate where modern construction relies on systems of barriers preventing moisture from penetrating the structure and building materials. Increased moisture within a wall whether old or modern, will drastically increase the likelihood of decay. Exterior paint is designed to prevent water penetration, but this also prevents evaporation. […]
Read moreJust because a home is old does not mean it is cold. Insulating an old home should be carefully studied to ensure you are not introducing more problems than resolving. Before tackling old home insulation, a little history about old home construction helps clarify why modern technology for old, historic, and very old homes is […]
Read moreBefore even discussing Radiant Barrier, it is important to understand all the issues with cold climate insulating and retrofitting an old house or modern home with insulation. There is a plethora of issues and technical problems that must be addressed and understood which, brings into the discussion, talk to the pros, the real ones who […]
Read moreNormally, heat rises but without proper ventilation in the attic, heat does not rise but migrates. Proper ventilation prevents moisture buildup from the heated air which, will quickly bring on other problems such as, bacterial buildup, mold growth, wood rot, popped shingles and ice dams in the winter. Without proper attic ventilation, air becomes stagnant […]
Read moreThermal insulation such as fiberglass, does not usually live up to its R-value unless certain criteria are met. Classic insulation absorbs heat and then re-emits that heat into the structure and or building materials around it. The role of thermal insulation is to SLOW conductive (heat moving through solid objects) heat flow. Think of a […]
Read moreUnderstanding what house wrap is designed to do and not do will help understand the control layers in a wall. House wrap is a water resistive (not waterproof) barrier (WRB) and is used to prevent liquid water from entering the wall cavity from the outside elements/atmosphere. This means, WRB is permeable to water vapor and […]
Read moreWhether you are constructing a new building or renovating an existing structure, there are many types of insulation to choose from. Quality insulation should maximize energy savings and reduce the transfer of heat to combat temperature extremes in the summer and winter. The Innovative Insulation team has compiled a list describing the many different options […]
Read moreThere are several myths and misconceptions about radiant barrier. Being the world’s largest manufacturer of radiant barrier, we at Innovative Insulation feel it is our responsibility to provide you with accurate, truthful information about radiant barrier and the benefits it can bring. We started this blog as way for us address myths and misconceptions about […]
