As a slim and highly efficient thermal multi-foil insulation for use in roofs, walls and floors, Alumaflex® is ideal for barn or loft conversions and in general timber frame construction. The proven, high performance product has UKAS accreditation and thanks to further investment by IPP (Magply), was also awarded LABC Certificate No EW 1045 in July.
Alumaflex® comprises four components in 14 layers which include aluminium foil bubble, aluminised foil, fibre wadding and polyethylene foam. It was assessed by LABC for ‘Energy Economy and Heat Retention’ with the registration meaning Alumaflex® is recognised by Building Control for use in England, Wales and Scotland although the product is normally used in conjunction with additional insulation such as PIR or mineral wool, to achieve the required U value.
Manufactured in the UK by IPP, Alumaflex® is very versatile and installer-friendly, being initially fixed with stainless steel staples, before normally being secured with battens to create a cavity.
Thanks to its versatility, Alumaflex® can help architects and other specifiers achieve the highly sought after PassivHaus standard for airtightness and perform as a vapour control layer by taping the joints. With its reflective foil finish, it is effective in both winter and summer, being that it retains warmth in the cooler months, but reflects heat on hot days therefore offering greater comfort for building occupants, as well as lower energy bills.
At just 25-30 mm thick and with a standard roll sizes of 1.2 x 8.33m and 10m long, it is easy for builders to handle and fix, working around complex details; making Alumaflex® an obvious choice to achieve thermal integrity, avoiding cold bridges. It will also accommodate movement in the building without tearing.
