Cold and heat insu­la­ti­on in one.

ISUM MF14 – the inno­va­ti­ve ener­gy-saving, mul­ti­func­tio­n­al way. Noti­ce­ab­ly war­mer in win­ter and signi­fi­cant­ly coo­ler in sum­mer. The uni­que sel­ling point of ISUM MF14 is its14-lay­er struc­tu­re (hybrid con­struc­tion). The two outer sur­faces each con­sist of a fab­ric-rein­for­ced and alu­mi­num-coated poly­es­ter film and have an infra­red reflec­ti­ve pro­per­ty. Sand­wi­ched bet­ween them are 4 poly­es­ter foils that are metal­li­sed on both sides, sepa­ra­ted by 2 lay­ers of poly­es­ter fleece and/or 6 of fle­xi­ble poly­ethy­le­ne foam. This struc­tu­re pre­vents ther­mal radia­ti­on from pene­tra­ting the hybrid mate­ri­al, reflec­ting it inwards or out­wards, depen­ding on the direc­tion of irra­dia­ti­on. You can read more about this in the glos­sa­ry under Emis­si­on coef­fi­ci­ent ε, which for ISUM M14 is εi = 0.04, as recent­ly tes­ted and repeated­ly veri­fied by the Fraun­ho­fer Insti­tu­te for Buil­ding Phy­sics IBP Stutt­gart: test report no. P15-085.1/2017 of 2.5.2017. This emis­si­on coef­fi­ci­ent cor­re­sponds to a reflec­tance of 96%.

Cold & heat insu­la­ti­on In con­junc­tion with tra­di­tio­nal insu­la­ti­on mate­ri­als and insu­la­ting com­pon­ents, ISUM MF14 hel­ps to “slow down” the com­po­nent-spe­ci­fic heat flow in both direc­tions to 4% (in sum­mer and win­ter con­di­ti­ons). A reduc­tion in trans­mis­si­on heat loss of up to 96% can thus be assu­med in win­ter, and in sum­mer a reduc­tion in solar heat input of up to 96%. The effec­ti­ve­ness of ISUM MF14 depends on the buil­ding-spe­ci­fic struc­tu­ral and cli­ma­tic con­di­ti­ons. The decisi­ve fac­tor is tech­ni­cal­ly pre­cise instal­la­ti­on as heat insu­la­ti­on sur­roun­ded by air on both sides.

It is true to say: Ener­gy that is reflec­ted does not have to be insu­la­ted against
