Super Foil (Multifoil) Insulation for Lofts – Including ThermaWrap

Looking for a space-saving insulation upgrade after spray foam removal? Super foil (multifoil) insulation is a modern solution that uses reflective layers to help improve thermal comfort—often with a slimmer build-up than traditional quilt insulation. We install foil insulation systems (including ThermaWrap) as part of a practical loft upgrade, tailored to your roof space and ventilation needs.

What Is Super Foil / Multifoil Insulation?

Super foil insulation (also called multifoil) is made from multiple reflective layers combined with insulating materials. The reflective surfaces help reduce radiant heat transfer. When installed correctly as part of the right roof build-up, it can support a warmer loft space in winter and reduce overheating in summer.

Therma Wrap Foil insulation, contrary to many traditional insulation materials, does not take up much space, which makes it the great solution for lofts and attics, where room is often limited. Thermal foil is relatively thin, thus is possible to install it in narrow and tight places. Therma Wrap foil insulation works also as a barrier to humidity, and it helps with moisture regulation. Therefore, it provides protection from the condensation of water vapour on walls, ceilings and roof planes. Moisture control is essential for counteraction against mould and maintaining the healthy quality of air in rooms. Therma Wrap Foil, in contrary to heavier insulation materials, is easy and light to maintain and cut, so its transport and installation are relatively simple and clean. Thermal foil insulation is also durable and long-lasting due to its longevity and immunity to pests. Those qualities make therma wrap foil insulation a smart investment for homeowners who are looking for a reliable insulation solution.

Why Homeowners Choose Foil Insulation After Spray Foam Removal?

After removing spray foam, homeowners usually want the loft to be:

• Inspect-able again (clear view of rafters and roof timbers)

• Better controlled for moisture and condensation risk

• Neat, light and space-efficient (especially where headroom is limited)

• Professionally documented for selling or remortgaging

Foil insulation can be a great option when you want a clean finish and minimal loss of space.
