Vi har valgt et isoleringsunderlag, som allerede er udstyret med en aluminiumsfolie som dampspærre. Skal underlaget lægges med sølvlaget opad eller nedad?
We have chosen an insulating underlay that is already equipped with an aluminium foil as a vapour barrier. Is the underlay laid with the silver layer facing upwards or downwards?
Underlaget lægges med den belagte side opad. Læg underlaget med aluminiumsbelægningen let overlappende, og lim samlingerne med aluminiumstape. Nogle af aluminiumsunderlagene har allerede en integreret klæbeflade.
The underlay is laid with the coated side facing upwards. Lay the underlay with the aluminium coating slightly overlapping and glue the joints with aluminium adhesive tape. Some of the aluminium underlays already have an integrated adhesive surface.
