Kingspan Thermaroof TR27 Flat Roof Board
Kingspan Thermaroof TR27 Flat Roof Board
Kingspan Thermaroof TR27 is a flat-roof PIR board used beneath fully adhered single-ply membranes and compatible bituminous waterproofing systems.
Its coated-glass tissue faces give the board a surface intended for these roofing applications. It should not be replaced with a foil-faced general-purpose PIR board without approval from the waterproofing supplier.
Install dry boards in a staggered pattern and apply the roof covering within the permitted exposure period.
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.
Key Features
· Flat roof PIR with coated-glass tissue facings
· For fully adhered single-ply and compatible bituminous systems
· Warm roof construction
· Multiple thicknesses
Common Uses
· Fully adhered single-ply roofs
· Built-up felt systems
· Warm flat roofs
Installation
Cut boards or rolls accurately, close every joint and keep the insulation layer continuous at corners, openings and service penetrations. Use the fixings, tapes, membranes and covering layers stated for the selected construction.
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
