40mm Kingspan Thermapitch TP10 Roof Insulation Board

The 40mm Thermapitch TP10 is an exceptional PIR insulation board designed for pitched roofs, whether they are slated or tiled. It is appropriate for both retrofit and new build projects, and comes in various thicknesses. The 40mm insulation boards are simple to handle and cut, guaranteeing a smooth installation process.

The 40mm Kingspan TP10 highlights include being one of the most thermally efficient insulation products commonly used for pitched roofs/attic spaces, suitable for creating usable attic spaces or attic renovation projects, reducing heat loss through the roof which can help save on energy costs, not being susceptible to sagging over time, and meeting the Robust Details for Part E of the Building Regulations in England and Wales.

Here are some possible rewrites for the section "Applications":

1. Recommended for new builds or re-roofing, can be used as unventilated insulation between and under rafters.
2. For loft insulation conversion projects, is recommended as ventilated insulation between and under rafters.
3. 40mm Kingspan Insulation is also suitable as unventilated insulation between and over rafters for new builds or re-roofing.

The Facings

During the manufacturing process, Kingspan 40mm PIR is bonded with a low emissivity composite foil on both sides, which serves as a reflective surface to enhance the thermal resistance of any unventilated cavity next to the board.

The Core

40mm Kingspan Thermapitch TP10's core is made using Nilflam® technology, which is a top-quality fiber-free rigid thermoset polyisocyanurate (PIR) insulant. The manufacturing process uses a blowing agent with zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

Compressive Strength

When tested to BS EN 826:2013 (Thermal insulating products for building applications. Determination of compression behavior), 40mm Kingspan PIR insulation usually surpasses a compressive strength of 140 kPa at 10% compression.

Water vapour resistance

When tested in accordance with BS EN 12086:2013 (Thermal insulating products for building applications. Determination of water vapor transmission properties), the product typically attains a resistance well above 100 MNs/g.

Durability

The longevity of 40mm TP10 is reliant on proper installation, supporting structure, and usage conditions. With correct installation, it can potentially have an unlimited lifespan.

Fire performance

40mm Kingspan Insulation TP10 has an F Euroclass rating under System 4 AVCP. When utilized in pitched roof constructions and placed under a suitable roof covering, it can fulfill national criteria for external fire exposure.
