Stylite Tapered Roof Insulation can be used as part of a new build roofing system or as an overlay solution for existing flat roofs.

It creates a fall that channels water to drainage outlets, preventing problems such as ponding that can lead to premature failure of the waterproofing system. Tapered insulation also removes the need for a structural roof fall, and can therefore help reduce the cost of the overall roof project.

Tapered Roof InsulationCreating a fall for flat roofs

Stylite Tapered Roof Insulation can be used as part of

a new build roofing system or as an overlay solution for

existing flat roofs. It creates a fall that channels water to

drainage outlets, preventing problems such as ponding that

can lead to premature failure of the waterproofing system.

Tapered insulation also removes the need for a structural

roof fall, and can therefore help reduce the cost of the

overall roof project. Manufactured off site, from high density

Expanded Polystyrene (EPS), tapered blocks are bespoke

to suit your project specific requirements.

EPS offers the best cost to performance ratio of any

insulation type. With thermal conductivity from as low

as 0.030W/mK our Tapered Roof Insulation can help

designers achieve the current Building Regulation u-value

requirements.

Once the Tapered Roof Insulation is installed an EPDM

or Single Ply waterproofing membrane can be applied to

complete the roof.

Typical Water Drainage

Thermal Performance

Water Managment - one of the main functions of a cut

to fall roof, new build or refurbishment is to control the flow

of water and negate all standing water that can lead to

premature failure of the waterproofing system.

Water drainage should be designed in accordance with

BS EN 12056-3:2000 (Gravity drainage systems inside

buildings. Roof drainage, layout and calculation).

For tapered roof schemes U-value calculations are not

as straight forward as other structural elements because

of varying thicknesses and layouts of the insulation.

The average U-value can only be calculated when the

full scheme of falls has been specified. They should be

calculated in accordance with BS EN ISO 6946: 2007

“Building components and building elements – Thermal

resistance and thermal transmittance – Calculation

method”. Call us now for a U-Value Calculation on

Design Considerations

Stylite Tapered Roofing Insulation - Technical Datasheet - 03

Tapered Roof InsulationTechnical DatasheetStylite

Insulation Solutions

Roof Design: Consideration should be given to the

recommendations of BS 6229:2003 (Flat roofs with

continuously supported coverings). Correctly designed

tapered insulation systems not only provide positive

drainage and appropriate thermal insulation – they can

also help to extend the life of the roof waterproofing

membrane.

Falls: The fall on a flat roof should be constant and steep

enough to ensure that rainfall does not pond. Typical falls

are 1:60 or 1:80, although we are able to manufacture

tapered pieces to any bespoke fall in increments of 1mm

to suit any roof size or layout.

Fire Performance: The fire rating when tested to

BS EN 13501-1:2007 + A1:2009 “Fire classification

of construction products and building elements.

Classification using test data from reaction to fire tests”

will be dependent upon the waterproofing system

specified, our EPS can be supplied with a Flame

Retardant Additive (FRA) if required.

Roof Loading: EPS tapered insulation is suitable for use

on roof decks that are subject to limited maintenance foot

traffic. Walkways should be provided on roofs requiring

regular pedestrian access. When the roof is complete,

protective boarding should be laid if additional site work is

to be carried out.

Identification: All our Tapered Roof Insulation blocks are

labelled according to their installation position as identified

on the system designers layout. This ensures a quick, yet

accurate installation on site.
