Standing Seam Roofing – Introduction

A standing seam metal roof is formed by laying long-span metal sheets on top of the building, after which these sheets are “seamed” together by folding or interlocking them in specific distances, providing a homogeneous roof that is extremely durable and weather proof. The standing seam system can be comprised of a single skin sheet for basic applications, or can have two layers of metal enclosing various performance enhancing components such as mineral wool insulation & vapor barriers.

Advantages of Standing Seam Roofing

  • Superior Aesthetics – an Infinite Variety of Color and Shape Finishes
  • No Through Fasteners Provides a Continuous Weather Tight Roof
  • Tapered Sheets for Roofs which are Curved in Plan or Curved in Plan and Section
  • Simple Waterproofing Detailing
  • Sheet Lengths up to 150 Meters Long
  • Excellent Resistance to Wind Uplift
  • Fully Integrates with Roof Lights and Accessories
  • Available in Aluminum or Galvanized Steel Sheets
  • Simple Fast Track Installation.
  • Non-Combustible Roofing System
  • No Leaks
  • Outstanding Structural Performance
  • Can be Rolled on Site, which Allows Spans Lengths that Exceed Factor-Rolled Sheets

Typical Components of Standing Seam Roof

  • Liner Sheet (Base Sheet)
  • Halters with Thermal Break Pads
  • Seam Sheet (Top Sheet)
  • Mineral Wool Insulation
  • Vapor Barrier

Standing Seam Roof Installation Procedure

  • Liner Sheet (Base Sheet) is installed using mechanical fixing on the existing building structure. Spacing and type of fixing accessories is determined by the overall system design.
  • If required, vapor barrier and mineral wool insulation are installed on top of the liner sheet and fixed mechanically or using adhesive.
  • Hat furring (omega) channel is installed perpendicularly to the liner sheet to form a grid. Spacing of furring channel is determined by the designer.
  • Insulated halters are installed mechanically on the furring channel to form the supporting structure of the seam sheet.
  • Roll forming machine is lifted to the roof level and raw metal coils are rolled into the seam sheet directly in the required installation location.
  • After aligning and fixing the seam sheets, seaming machine is applied in between seam sheet panels to form the interlocking joint which prevents any penetration by weather elements.
  • Once the main roof is completed, gutter (perimeter covers) and flashing (vertical covers) are installed to complete the system installation.
  • Sealant is applied where required based on system design.

Insulated Composite Panels – Introduction

Insulated Composite Panel provide an extremely cost effective and fast track solution for both new buildings and refurbishment applications.

Insulated composite panels are available with aluminum or steel external and internal skin, in a wide range of gauges and paint finishes.

Different types of insulation core are available to achieve different levels of fire resistance, thermal insulation, or acoustic insulation.

Advantages of Insulated Composite Panels

  • Superior Aesthetic Properties
  • Cost Effective Fast Track Construction Solution
  • Reduces the Amount of Structural Support and Foundations Required
  • System Builds into a Complete Lightweight Roof/Wall Construction
  • Fully Integrates with Glazing and Accessories
  • Excellent Corrosion, Chemical and Weather Resistance
  • Panels can be Curved to Tight Radii and Sculpted to almost any Shape
  • No Exposed Sealants – Reduces Dirt Retention and Subsequent Panel Staining
  • Airtight Construction Reduces Plant Running Costs and CO2 Emissions
  • Reliable Thermal Performance Over the Life of the Building
  • Eliminates the Risk of Interstitial Condensation and Cold Bridging within the Panel
  • Available in a Wide Range of Colors
