IKO Coldseal Self Adhesive Felt is a high performance quick to apply roofing felt ideal for use on flat roofed domestic buildings where a robust, long lasting built up felt roofing system is required.

Coldseal is a two-layer high performance system, which was originally developed for small roofs, such as those over garages, porches, extensions and dormer windows etc. However, the fire-safe benefits of Coldseal are equally applicable for
large projects.

Coldseal has been accreditation from the British Board of Agrement, no. 02/3916.

The self-adhesive application process, using no hot bitumen, gas torches or large amounts of messy liquids, makes it an ideal option for experienced contractors or competent DIY installers alike.

IKO Coldseal felts consist of two products to create a system.Coldseal-SystemColdseal-Top-Sheet

IKO 8m Coldseal Underlay is manufactured with an inert glass fibre base, coated with SBS modified bitumen. The upper surface has a non-removable polyethylene film, with a removable release film to the underside.

IKO 6m Coldseal Top Sheet is manufactured with a high performance polyester base, coated with SBS modified bitumen. The upper surface is finished with a slate mineral. The underside is protected by a release film, which is removed during installation. The Coldseal slate mineral has a 75mm selvedge for ease of lap jointing.

Both the capsheet and underlay have specially formulated self-adhesive additives in the coating.

The IKO Coldseal Self Adhesive felts are expected to last over 20 years when installed together as a 2 layer roof waterproofing system.

Packaged in silver and gold wrappers with full instructions.

How much do I need?

Coverage: First calculate the flat area of the roof in square metres (width x length) and add 10% to allow for side and end laps. Next, measure the total length of the roof perimeter in metres and multiply this figure by 0.3 to give the additional material required for edge details. Add this figure to the roof area previously calculated, and for:

Coldseal Self Adhesive Top Sheet: Divide by 6 to give the number of rolls required.

Coldseal Self Adhesive Underlay: Divide by 8 to give the number of rolls

Additional materials:

- IKOpro SA Bitumen Primer for self-adhesive membranes
- IKOpro High Performance Felt Lap Adhesive - - Galvanised clout nails- 19mm with extra large heads.
- Hardboard strips cut to 75mm width to act as formers for the drip edges. These should be coated on both sides with IKOpro SA Bitumen Primer.
