Recticel Powerdeck F Flat Roof Board

Recticel Powerdeck F is a flat-roof PIR board compatible with built-up felt, mastic asphalt and selected single-ply membranes. Its >150 kPa compressive strength gives the roof build-up a firm, stable insulation layer.

The smaller 1200 x 600mm board is easier to handle on roofs than a full-size general-purpose sheet. It is used in both refurbishment and new-build warm roofs.

Stagger the boards, keep all edges supported where required and follow the waterproofing manufacturer's fixing and preparation instructions.

Why Choose This Product?

Choose this because its facing and board properties are made for the stated waterproofing system. A cheaper general-purpose PIR board is not automatically an acceptable substitute on a flat roof.

Before You Install

·        Substituting general-purpose PIR for a roof board with different facings.

·        Leaving boards exposed to rain or site traffic.

·        Ignoring the waterproofing manufacturer's compatibility requirements.

·        Laying four board corners at one point instead of staggering joints.

Frequently Asked Questions

Can this replace standard PIR?

Only where the waterproofing and roof-system documents permit it. Flat-roof board facings are selected for particular membranes and adhesives.

Can it be left outside overnight?

No. Keep boards dry and cover the installed area promptly.

Should joints be staggered?

Yes. Stagger joints and avoid lining up four board corners.

Can I walk directly on it?

Limit traffic and use temporary protection. The finished roof layers distribute loads.

Which thickness do I need?

That comes from the required roof U-value and the complete roof build-up.

What You'll Need

·        Vapour-control layer

·        Roof insulation fixings

·        Compatible waterproofing system

·        Protection board where specified

·        Tapered firrings or tapered insulation where falls are required
