Insulation Strapping – Ideal for Wall, Ceiling, and Underfloor Installs
Insulation strapping proves exceptionally beneficial in situations where uneven joist spacing poses a risk of insulation batts falling out during or immediately after installation. While a securely positioned insulation batt without any strapping is commonly referred to as a “friction fit,” we strongly advise utilizing strapping across the joists at a 90-degree angle and stapling it firmly against the joists. This approach guarantees that even in the event of potential slippage over time, the insulation will remain intact between the joists, ensuring long-lasting and effective insulation for your home throughout its lifespan.
Insulation Strapping for Walls
For the installation of thermal wall batts with an R1.5 or R2.0 rating, we highly recommend the use of strapping. These thermal batts are relatively less rigid compared to acoustic and high-density batts, making it necessary to employ strapping to ensure their proper positioning. However, when using rigid acoustic insulation in wall cavities, insulation strapping is not required as long as the insulation is accurately cut to size and fits securely between the joists.
Insulation Strapping for Ceilings
When installing ceiling batts prior to plastering, it is advisable to use strapping to secure them in place. This precautionary measure prevents the batts from falling out either before or during the plasterboard installation. It’s important to note that maintaining a small gap between the batts can significantly compromise the thermal efficiency of the insulation. However, when installing insulation from within the roof space, strapping is not necessary. In such cases, you can simply lay the batts on top of the plaster below.
Insulation Strapping for Underfloors
When it comes to installing underfloor insulation batts, strapping is indeed essential. Unlike other types of insulation that benefit from the support of plaster, underfloor insulation lacks this advantage and requires strapping to maintain its position over the years. It is crucial to pull the strapping tight and securely staple it in place to prevent the underfloor insulation from falling out from between the joists. This ensures that the insulation remains intact and effective in providing thermal insulation beneath your floor.
