Guide

Insulated or non-insulated building?

Whether a building needs insulation depends on what you keep in it and what you do there. Between an open canopy and a fully insulated building there are several steps.

Protection levels

From an open canopy to a fully insulated building

Five levels of protection for your goods: choose roof, walls, felt and insulation to suit the use.

  1. 1Drawing of a canopy

    Canopy

    Especially popular in farming for protecting hay and in motoring for protecting vehicles.

    • Roof
    • Walls
    • Felt against condensation
    • Insulation
  2. 2Drawing of a non-insulated building

    Non-insulated building

    For storing farm and other products, machinery or goods out of the weather.

    • Roof
    • Walls
    • Felt against condensation
    • Insulation
  3. 3Drawing of a felt-protected building

    Felt-protected building

    For storing all kinds of goods, with extra felt protection of the roofing.

    • Roof
    • Walls
    • Felt against condensation
    • Insulation · basic
  4. 4Drawing of a partly insulated building

    Partly insulated building

    Partial protection of products and goods from temperature effects; also suits services.

    • Roof
    • Walls
    • Felt against condensation
    • Insulation · partial
  5. 5Drawing of a fully insulated building

    Fully insulated building

    High protection of goods from the environment; ideal for business premises and work.

    • Roof
    • Walls
    • Felt against condensation · lv_pur
    • Insulation · complete, polyurethane core

Condensation

When felt or DRIPSTOP® is enough

In non-insulated or partly insulated buildings, condensation can form under the sheet when warm, humid air meets cold metal, and it then drips into the building.

Felt or the DRIPSTOP® layer bonded to the underside of the sheet holds this moisture and releases it again when the conditions change. It is recommended for halls, warehouses, canopies and farm buildings without classic insulation; properly insulated buildings do not need it.

Insulated panels

Three cores for warm buildings

  • Panel with a PUR core

    PUR (polyurethane foam)

    The most widely used core: excellent thermal insulation at low weight. A rigid foam injected between the two facings. Ideal where energy efficiency matters and there are no special fire requirements. Thicknesses: 15, 30, 40, 50, 60, 80, 100, 120 and 150 mm.

  • Panel with a PIR core

    PIR (polyisocyanurate)

    An upgrade of PUR with better fire resistance, even better insulation and higher temperature resistance, for industrial and business buildings where fire safety matters. Thicknesses: 30, 40, 50, 60, 80, 100, 120 and 150 mm.

  • Panel with a rock-wool core

    Rock wool

    A natural material made from volcanic rock: very good thermal and sound insulation and the highest fire resistance. Non-combustible, for buildings with the strictest fire rules. Thicknesses: 60, 80, 100, 120, 150 and 200 mm.

Terraces

Insulated canopies, too

With insulated wall panels, a covered terrace stays in use beyond the warmest months, into autumn and winter.
