BRITISH-MADE ISO & BES 6001 QUALITY
Extruded at IKO’s Derbyshire facility under BS EN ISO 9001, ISO 14001, and BES 6001 responsible sourcing standards, IKO Armourplan and Spectraplan membranes feature a multi-layer polymeric formulation stabilised against ultraviolet radiation in Slate Grey (RAL 7015) and Mid Grey (RAL 7046).

FLAME-FREE BONDING & BROOF(t4) FIRE SAFETY
Whether mechanically fastened or cold-adhered using polyurethane bonding agents, IKO Polymeric membranes require zero naked gas flames on site. Tested under BBA Certificate 05/4278, the finished roof build-up achieves the highest unrestricted BROOF(t4) external fire designation under BS EN 13501-5.

Benefits of IKO Polymeric Single-Ply

HIGH-TENSILE SCRIM REINFORCEMENT
Laminated around a high-tenacity polyester reinforcement scrim (Armourplan P and PSG grades) or a 300gsm fleece backing (Armourplan FSM), the membrane resists nail tear to EN 12310-1 and hailstone or foot-traffic impact to EN 12691 without splitting or delaminating.

MECHANICALLY FASTENED & WARM ROOF VERSATILITY

As illustrated in our mechanically fastened build-up diagram, IKO single-ply systems lock directly through high-density PIR thermal insulation and the vapour control layer into timber, plywood, or profiled metal decks using thermally broken tube fasteners, cutting wind-uplift loads and installation time on expansive London roofs.

Features of IKO Armourplan & Spectraplan

ADHERED FLEECE-BACKED BUILD-UPS & GUARANTEES
As shown in our adhered system diagram, fleece-backed IKO Armourplan FSM bonds into cold-applied IKOpro PU adhesive over tissue-faced PIR insulation boards, leaving a smooth, fastener-free surface across domestic extensions and roof terraces. Every installation is backed by an IKO manufacturer warranty of 15 to 25 years alongside our 10-year insurance-backed workmanship guarantee.

BREEAM SUSTAINABILITY & RECYCLABILITY
IKO Polymeric operates zero-waste-to-landfill manufacturing, incorporating reprocessed production trimmings and supporting high BREEAM ratings on sustainable London refurbishments.

Frequently Asked Questions

IKO Polymeric Flat Roofer London

What is the difference between IKO Armourplan (PVC) and IKO Spectraplan (TPE)?

IKO Armourplan is a polyester-reinforced polyvinyl chloride (PVC) membrane famed for its pliability around intricate skylight kerbs, parapets, and standing-seam profiles. IKO Spectraplan is a thermoplastic elastomer-olefin (TPE) membrane that is completely free of plasticisers, chlorine, and halogens, making it the preferred choice for BREEAM-led commercial developments and solar PV roofs.

Can IKO Polymeric membranes be used with standing seam profiles to mimic lead or zinc?

Yes. We hot-air weld extruded PVC standing-seam decor profiles directly onto Slate Grey or Lead Grey IKO Armourplan sheets, replicating the visual rhythm of traditional batten-roll lead or zinc on London conservation properties at a fraction of the structural weight.
