More and more home builders are recognizing the importance of insulation in achieving a good home energy envelope and the improved energy efficiency that home buyers are demanding. With raised-heel trusses, you not only get more space to put insulation, you also get trusses that offer greater curb appeal. Here’s how they can save you time and money.
Knowing what R-value and U-values mean is key to following energy issues and to selecting products that best suit the climate zone you are building in. R-value is essentially a product’s resistance to heat flow. Adversely, U-value measures the rate of heat transfer. This means that products with a lower U-value will be more energy efficient. It is tempting to think that these two values are direct opposites of each other, but there are some important differences to note.
We’ve come to understand that the quality of batt insulation relies heavily on the installation. No matter how good your insulation is, the way it is installed will determine your ability to reach increasingly stringent requirements for programs such as HERS, ENERGY STAR and LEED. Here’s some things you should focus on when installing batt …
Stringent new building codes require improved efficiency of building envelopes through better insulation. While more expensive insulation methods, like spray foam, may have greater R-values, it is possible to meet the required high R-values using less expensive fibreglass or cellulose insulation with a raised heel truss.
As efficient building envelopes become more of a priority for builders, you may be considering investing in triple-pane windows for the R-value they offer. The technology behind window design has improved in leaps and bounds as manufacturers attempt to overcome the poor insulation value that windows traditionally offer the home builder. Unfortunately, the improved insulation comes at a high price. Do triple-pane windows offer sufficient energy-saving to justify the investment?
Discerning construction professionals are turning to raised-heel trusses thanks to the increased attic space they produce. This space is then utilized for larger amounts of cheaper insulation which reduces the cost of insulation and provides a more effective building envelope and a greener home. Raised-heel trusses offer many environmental and cost-saving benefits.
Ventilating your attic is key to reducing moisture and avoiding mold. Attic ventilation is a critical factor to ensure that moisture and hot summer air issues are addressed correctly. This will help to preserve the structural integrity of your roof system, reduce energy costs in the warm summer months, improve the effectiveness of your insulation in the winter months and prevent the formation of ice dams.
As construction costs increase and building codes demand more effective building envelopes, construction professionals are looking to taller wall panels to fill in the gaps. OSB wall panels already make for a sustainable and cost-effective option but with longer length OSB wall panels, the efficacy of the building envelope is increased by creating fewer seams while costs, waste and installation time are reduced.
