All RAL colours can be delivered. For short delivery times, we provide some stock colours, which you can see on the right:

  • This system is the most economical
  • The insulation is made of soft faced glass fiber providing a good acoustical comfort
  • It is available with Isobloc and increased insulation thickness to improve overall thermal performance and reduction of thermal bridges
Insulation (mm) 40 60 80+ 100+ 120+
U-value W/(m²∙K)* 1.26 0.94 0.60 0.49 0.42
*The U-values are guaranteed for an installed product when the nominal thickness of the insulation is maintained in the middle of a purlin spacing of 1500 mm or more. // += with Isobloc

Standard colour

  • #01 / ~ RAL: 7044

Building System – Roofs – LPR1000
  • This system offers superior thermal efficiency and advanced condensation control by reducing the thermal bridge to a minimum. It also prevents the insulation being compressed at the location of the secondary framing elements
  • It increases insulation thickness through a spacer bridge

Building System – Roofs – LPR1000
  • It offers the best possible insulation up to 260 mm
  • It includes all the advantages of the bridge solution
  • It has a solid and aesthetic appearance thanks to the internal panel that acts as vapour barrier, best fire rating
  • Optional acoustic panel for increased noise absorption
  • Excellent solution for buildings with a high relative humidity inside

Assembling

Building System – Roofs – LPR1000

The normal horizontal purlin spacing can vary from 1.5 to 3 meters.

The roof slope can vary from 2 to 20%.

The LPR1000 roof panels are fixed to every purlin by self-drilling screws made out of stainless steel Cr/Ni 18.8. The screws are supplied with a slightly conical steel washer on to which an EPDM sealant is vulcanized. The EPDM is a flexible material in durable plastic. When the screw is tightened, the metal washer squeezes the EPDM creating a reliable seal between the fastener head and the washer thus assuring the water-tightness of the fixation.

(*) EPDM: Ethylene-propylene-terpolymer
