Cavity wall insulation

R-VALUE: 44.0, SUITABLE FOR: new construction.THERMAL PERFORMANCE: Insulated with cellulose: R-36.0. Insulated with high-performance fiberglass (R-4.5 per in.): R-44.0.PROS:• Optional 2x3 insulated wall and high-efficency fiberglass give potential for even higher R-values.• Large capacity for moisture storage allows the wall cavity to dry gradually.CONS:• Panels are often manufactured off site, trucked to site, and craned into place, which all add to cost.• Design may be subject to joist ...

R-VALUE: 40.0, SUITABLE FOR: new construction, retrofitTHERMAL PERFORMANCE: At R-3.5 per in., the cellulose in this system yields an overall value of R-40.PROS:• Familiar building process means lower labor costs with readily available materials.• If cellulose is used, the project has a lower environmental impact.• Large moisture-storage capacity allows wall cavities to dry gradually.CONS:• Fairly involved insulation process can add to labor costs.• Reduces interior space by 3%.

Sempatap Solid Wall Insulation - Sempatap Thermal is approved as an Energy Saving Product by the Energy Saving Trust and is an EST “Recommended” product for the insulation of solid wall homes. It has been tested by the National Physical Laboratory and figures produced by the Building Research Establishment show considerable carbon saving. It will reduce the ‘u’ value by nearly 30%. In fact on a three bedroom semi detached house the annual carbon savings are 798kg, 119kg higher than cavity…
