Customer Feedback

SuperFOIL SFTV 1L has received a wealth of positive feedback from our customers, with many praising its versatility and effectiveness in a variety of applications. Customers have found it particularly useful in insulating sheds, with reports of noticeable temperature differences even in high heat. By applying the SuperFOIL SFTV 1L to the walls and ceilings of their sheds, users have noted a significant reduction in heat radiation and more stable temperatures throughout the day.

One customer, in particular, reported using SuperFOIL SFTV 1L as a heat blocker for south-facing windows during a heatwave. The result? A much cooler room, demonstrating the foil's effectiveness in reducing heat transmission. Another customer used SuperFOIL SFTV 1L to insulate suspended timber floors in an old house. After applying the foil beneath the carpet underlay and laminate flooring, drafts were eliminated and the rooms felt noticeably warmer. The same customer also found SuperFOIL SFTV 1L useful as a vapour and air barrier in their well-insulated timber workshop, achieving a comfortable, steady temperature year-round.

SuperFOIL SFTV 1L has also proven to be easy to work with. Customers have reported it being easy to cut and lay, with one even reporting that it provided a noticeable difference in comfort when applied beneath conservatory flooring. Some users have utilised SuperFOIL SFTV 1L in loft spaces, not just for insulation, but also for cleanliness and brightness. This reflective foil can transform a dusty, old loft into a clean and bright space.

However, it's important to note that some users reported the 1.2m version of the product as being less robust than the 1.5m version. Some users also noticed pinholes when holding the product against the light, which may affect its effectiveness as a vapour barrier.

Overall, the majority of our customers are highly satisfied with the SuperFOIL SFTV 1L and have found it to be a beneficial addition to their insulation efforts. Despite some minor concerns, the general consensus is that SuperFOIL SFTV 1L is a high-quality, versatile product that is easy to work with and provides significant benefits in a range of applications.
