Insu­la­te your floo­rs, walls and roof with ISUM.

Flat and flexible. 
Paten­ted heat insulation 
– made in Germany 

Insu­la­te floor, wall and roof. High­ly effi­ci­ent with ISUM.

With 96 % heat reflec­tion for up to 58 % reduc­tion in hea­ting requi­re­ments*. ISUM — save ener­gy and pre­ser­ve living space.

14-layer of ISUM - floor, wall, roof insulation

Whe­re­ver air lay­ers are requi­red in a con­struc­tion, or for struc­tu­ral engi­nee­ring or simp­le con­struc­tion, the use of ISUM makes sen­se. In com­bi­na­ti­on with tra­di­tio­nal insu­la­ti­on mate­ri­als and insu­la­ting com­pon­ents, the requi­re­ments of GEG (form­er­ly EnEV) or KfW can be achie­ved with a lower lay­er struc­tu­re. Addi­tio­nal living space can be crea­ted by the pos­si­bi­li­ty of buil­ding slim­mer with the same insu­la­ti­on effect. This leads to a cost advan­ta­ge that is often unde­re­sti­ma­ted or not con­si­de­red. With a mate­ri­al thic­kness of only approx. 10 mm, ISUM is almost always approx. 10 times thin­ner than con­ven­tio­nal insu­la­ti­on. With space-saving and simp­le pro­ces­sing. For more space and more efficiency.

ISUM is mul­ti­func­tio­n­al. Ide­al for insu­la­ting floo­rs, walls or roofs. The space-saving insu­la­ti­on alter­na­ti­ve is quick, easy and clean to process.

*Examp­le: old buil­ding from the 70s. Living space approx. 140 m². Roof, walls and base­ment cei­ling insu­la­ted with ISUM. Heat requi­re­ment 78.4 kwh/m² (com­pa­red to 188.4 kwh/m² without insu­la­ti­on). Reduc­tion of hea­ting requi­re­ments: 58 %.

ISUM is so easy to pro­cess. No mat­ter whe­ther you insu­la­te the floor, the wall or the roof.

The strengths of ISUM are always evi­dent when a space-saving, uncom­plex and ener­gy-effi­ci­ent insu­la­ti­on solu­ti­on is requi­red. Easy to use, uncom­pli­ca­ted in instal­la­ti­on, clean in finish. Can be pro­ces­sed without respi­ra­to­ry pro­tec­tion and with simp­le tools and instal­led in a resour­ce-saving man­ner without waste.

Roof insulation - ISUM processing

ISUM for the roof

Under-raf­ter insu­la­ti­on with vapour bar­ri­er or dif­fu­si­ve raf­ter-moun­ted insu­la­ti­on. Both pro­fes­sio­nals as well as do-it-yourself enthu­si­asts quick­ly reco­gni­se the advan­ta­ges of the insu­la­ti­on foil, which is only approx. 10 mm thick. The film is cut to size and sim­ply stap­led on or under the rafters.

Processing of ISUM on wall - floor, wall, roof insulation

ISUM for the wall

Without loss of living space and com­plex con­struc­tions, the insu­la­ti­on foil is used for ener­gy-effi­ci­ent insu­la­ti­on from insi­de and out­side. This is the most space-saving solu­ti­on, espe­cial­ly for exis­ting buil­dings. Stap­le onto the walls to be insu­la­ted with spa­cer bat­tens. Done.

Processing of ISUM on ceiling - floor, wall, roof insulation

ISUM for cei­ling & floor

Com­plex sus­pen­si­ons with thick insu­la­ti­on inserts are a thing of the past with ISUM. Appro­pria­te spa­cing or sup­port bat­tens crea­te the air space. ISUM is moun­ted under­ne­ath. If requi­red, just clad it and the new, ener­gy-effi­ci­ent­ly insu­la­ted cei­ling is ready.

Base­ment cei­ling with Prussian

Buil­ding com­po­nent struc­tu­re: Base­ment cei­ling ca. 1850 — 1910
  • Pla­ned boards
  • Coal slag filling
  • Brick coved vault on steel girders

  • Imp­reg­na­ted coun­ter bat­tens (>24/48 mm)
  • Mois­tu­re-resistant mine­ral fib­re board (no plasterboard!)

Until 1850, pure brick coved vaults were still made. Bet­ween 1850 and 1910 steel gir­ders were used for the so-cal­led Prus­si­an coved vault.

From 1910, base­ment rein­for­ced con­cre­te cei­lings made of in-situ con­cre­te were common.
This was fol­lo­wed by hand-assem­bled steel-brick base­ment cei­lings. For cost rea­sons, floor cei­lings were desi­gned as woo­den beam cei­lings until 1950.
