Pir Floor Insulation Thickness

In this scenario a rigid foam insulation is usual and as you d want the same u value in the roof we need the same thickness of insulation 180mm.

Pir floor insulation thickness. λ 0 034 0 040 high quality mineral wool b lower density. 100 150 kg m3 mineral wool c high compressive strength. Floor insulation can cut your heating bills keep your home warmer and block draughts. Fr5000 closed cell formulation offers excellent resistance to moisture and has a high compressive strength making it the ideal solution for a range of fl ooring applications.

Pir insulation solution featuring a super low lambda value of 0 021 w mk ensuring regulation compliance can be achieved with minimal insulation thickness. Pir has such a high thermal performance it requires only half the thickness of traditional mineral based insulation products. Insulating a suspended timber floor. Floor insulation pir ak the thermal conductivity value stated at 10 ºc for pir ak and pir ak 500 panels is 0 023 w mk one of the lowest values on the market.

A better thermal insulation performance. Lay floor insulation boards quinn therm qf pir insulation boards or quinn lite pac eps insulation boards on top of the dpm in a break bond pattern across the whole floor. 40 50 kpa mineral wool d water absorbability resistance.

The following chart is a comparison of how much sikatherm pir al 1 with thickness of 100 mm 0 022 w m k and an alternative mineral wool based 0 040 w m k thermal insulation with thickness of 180 mm. Achieving a u value of 0 20w m meaning your roof will be better insulated than your walls will need 120mm thickness of rigid foam or 200mm of mineral wool or natural insulation. λ 0 023 thermano vs. The main advantages of pir core panels include flat roofing insulation system.

32 kg m3 thermano vs. 200 kpa thermano vs. Pir typically cut into boards can be used in insulated metal panels wall cavities and as insulated plasterboard. Note wall insulation in the perimeter walls should also extend at least 150mm below the top of the floor insulation boards.
