Certification and Testing

Reaction to Fire

KS1000SRW Roof Panels are classified B-s1,d0, when tested on the internal face of the product, according to the European Reaction to Fire classification system (Euroclasses) BS EN 13501–1: 2007+A1: 2009 under the certified name KS 1000SR and BS EN 13501-1:2018 under the certified name KS1000 SR when using the following internal liners:

CLEANsafe 15, CLEANsafe 25, CLEANsafe 55, CLEANsafe120, AQUAsafe 55 

Please contact Kingspan Tech-eXchange for Information relating to the external face.

Roof Applications

KS1000SRW Roof Panels are tested to:

Broof(t4) to BS EN 13501-5: 2016 under the certified name KS1000SRW for panel thicknesses 40mm - 80mm for roof pitch of 0° - 10° 

Broof(t4) to BS EN 13501-5: 2016 under the certified name KS1000SRW for panel thicknesses 40 – 80mm for roof pitch of >10°

Insurer Approvals

KS1000SRW Roof Panels are tested to:

LPS 1181 Part 1: Issue 1 Requirements and tests for built-up cladding and sandwich panel systems for use as the external envelope of buildings certified to:

LPS 1181-1 Grade EXT-B under the certified name KS1000SRW (roof and wall panel) for thicknesses 40 – 80mm

Insurer approvals are large scale testing regimes that provide objective third-party testing, which is underpinned by quarterly, bi-annual and annual factory surveillance audits (depending on the region) to verify compliance. Insurer approvals are subject to panel thickness, cover width, orientation, method of assembly, steel coating and manufacturing facility. Please contact Kingspan Tech-eXchange for further information.


KS1000SRW Roof Panel is a through-fix sinusoidal profiled insulated roof panel which can be used for building applications with roof pitches of 4° or more after deflection.

Available Lengths

Standard lengths: 1.8 - 14.5m

Longer lengths (non-standard): 14.5 – 18.2m

Shorter lengths (non-standard): Below 1.8m

Note: Additional costs and transport restrictions may apply for non-standard lengths. All lengths may change for export (outside of the UK & Ireland).

Insulation Core

KS1000SRW Roof Panels are manufactured with a polyisocyanurate (PIR) core.


Kingspan Insulated Panels produced in the UK are certified to BES 6001 (Framework Standard for the Responsible Sourcing of Construction Products) ‘Very Good’. 

All Kingspan Insulated Panels manufacturing facilities across the UK and Ireland are 100% Net Zero Energy. In addition, facilities located in Kingscourt, Holywell and Sherburn generate renewable energy onsite which contributes to that sites energy mix. 

Kingspan Insulated Panels procure steel that is made from 15 – 25% recycled content. Kingspan insulated panels directly contribute to BREEAM® / LEED® credits.

Air Leakage

An air leakage rate of 3m3/hr/m2 at 50Pa or less can be achieved when using Kingspan insulated roof and wall panels.

For information on detailing required to achieve lower air leakage rates please contact Kingspan Tech-eXchange.


Sound Reduction Index (SRI)

SRI; 20; 18; 20; 24; 20; 29; 39; 47

* Frequency

KS1000SRW Roof Panels have a single figure weighted sound reduction Rw = 25dB. Results are based on panels of similar profile and core material.

Materials - Substrate

Metallic protected steel to BS EN 10346:2015.

Please contact Kingspan Tech-eXchange for information on other substrates.

Coatings - External Weather Sheet

Kingspan XL Forté: Consists of a multi-layer organic coating, embossed with a traditional leather-grain finish.

Kingspan Spectrum: Consists of a coated semigloss finish with slight granular effect.

For Reaction to Fire performance of external weather sheets please contact Kingspan Tech-eXchange.

Coatings - Internal Liner Sheet

Kingspan CLEANsafe 15: The coating has been developed for use as the internal lining of insulated panels. Standard colour is “bright white” with an easily cleaned surface.

Kingspan CLEANsafe 120: The coating has been developed for use as the internal lining of insulated panels where a high level of cleanliness and hygiene is required, and the panels are to be cleaned down on a regular basis.

Kingspan AQUAsafe 55: The coating has been developed for use as the internal lining of insulated panels for swimming pools and other high humidity internal environments.

For reaction to fire performance of panels with above internal liners please see certification and testing section.
