21mm Unilin FR/TP Warm Roof Insulation Decking is an insulated panel made of 15mm PIR rigid foam insulation core bonded to 6mm WBP grade plywood used for new and refurbishment flat roof applications.
Unilin FR/TP Thermal Ply Flat Roof Insulation Board is faced to the under side with a gas-tight foil facer, bedding the panel onto a bed of mastic creates a continuous vapour control layer.
FR/TP Pre-insulated Roof Decking is designed for use on new roofs or upgrading the thermal performance of existing roofs.
The roof construction is a critical element in the building fabric and is an area at very high risk of heat loss.
A warm roof application with all the insulation above the joists is considered best practice.
Where insulation between the joists is required to reduce the overall height please note the insulation above the deck should have a higher thermal resistance than that of the insulation between the joists.
Unilin FR/TP provides rapid weather proofing and reliable long term energy savings for buildings.
The thermal conductivity of the PIR insulation board is 0.022 W/mK (Lambda value).
The thermal conductivity of the 6mm WBP Plywood is 0.14 W/mK (Lambda value).

Unilin FR/TP Flat Roof Insulation Decking Installation Guide:
· A warm roof application with all the insulation above the joists is considered best practice.
· Where insulation between the joists is required to reduce the overall height please note the insulation above the deck should have a higher thermal resistance than that of the insulation between the joists.
· The boards should be fixed to a minimum of 50mm thick joists at 600mm centres max with the plywood uppermost.
· Boards should be staggered and butted.
· Each edge should have a minimum bearing of 20mm on the joist.
· All edges should be supported - add noggings where necessary.
· Stagger fixings where boards are butted.
· Boards should be embedded in vapour resistant mastic to provide a vapour control layer in conjunction with foil facing.
· Mastic should be laid wide enough to facilitate 2 panel edges and be continuous around all edges.
· The boards should be fixed with low profile screw fixings, placed at 200mm centres around the perimeter of the boards and at 300mm centres along any intermediate supports.
· All fixings should penetrate the joists by a minimum of 35mm and be placed 12mm from the edge of the insulation, and no further than 50mm from any corners.
· Care should be taken to ensure that the heads of any fixings are flush with the plywood surface and not over-driven.
· The roof should be fire protected to the underside by applying a layer of plasterboard or other approved material.
· Thermal Ply is suitable for maintenance traffic loadings only.

We can help to calculate price per m2 or linear meter (one meter in length) cost, please just contact us via phone 02081910776, email or live chat. Alternatively, you can work it out yourself quickly and easily: to get cost per meter square please divide price shown in orange area by ''Required area (m2)'' Example price of £28.80 divided by board coverage 2.88m2 = cost of £10.00 per m2.
INSTALLERS
No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.
4 TIPS FOR CHOOSING THE BEST INSULATION INSTALLER
1. Thermal inspection picture in portfolio
It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.
2. Reviews
Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.
3. Compare prices
Comparing prices will also ensure companies can’t take advantage of you and give you a fair price.
4. Word of Mouth
The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.
Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
