Overview of Mannok (Quinn Therm) PIR Insulation Boards

Mannok PIR Insulation Boards, formerly known as Quinn Therm, are rigid polyurethane foam (PIR) insulation boards used for thermal insulation in buildings.

Mannok offers an extensive range of PIR insulation products for use in floor, wall and roof applications in both new build and retrofit projects. The boards are available in a range of thicknesses from 20mm to 150mm and achieve thermal conductivity between 0.022 W/mK and 0.026 W/mK, making them some of the most thermally efficient rigid board insulations available.

Key Features

  • Excellent thermal performance - thermal conductivity as low as 0.022 W/mK
  • High compressive strength
  • Dimensional stability
  • Durability - will perform for life of building
  • Zero Ozone Depletion Potential
  • Low Global Warming Potential - certified to ISO 14001
  • A+ BRE Green Guide rating
  • Products are CE marked and have BBA and IAB accreditation
  • Solutions for new build and refurbishment
  • Range of products for floors, walls and roofs
  • Variety of facings: composite foil, fleece, plasterboard laminates

Mannok PIR Insulation Product Range

Mannok offers the following PIR insulation boards:

  • Therm Floor (MF) - For ground floors, suitable for underfloor heating
  • Therm Cavity (MC) - Partial fill cavity wall insulation
  • Therm Wall (MW) - External wall insulation, internal drylining
  • IsoShield - Full fill cavity wall insulation
  • Therm Laminate-Kraft (MLK) - Insulated plasterboard for walls and ceilings
  • Therm Laminate-Foil (MLF) - Insulated plasterboard with foil facing
  • Therm Roof (MR) - Pitched roof insulation
  • Therm Roof (MFR) - Flat roof insulation, various facings

Applications

Typical applications for Mannok PIR Insulation Boards:

  • Cavity walls - full fill or partial fill

Condensation Control

Mannok PIR Insulation boards manage condensation through the foil facings which have an extremely high vapor resistance. This allows the foil facings to be formed into an air and vapor control layer (AVCL) by taping the joints between boards with metalized tape. The AVCL prevents water vapor from entering the construction and condensing on cold surfaces.

In constructions where an AVCL cannot be formed by taping Mannok board joints, a separate proprietary AVCL membrane must be installed. Accessory products like vapor control layers, membranes, and tapes work together with Mannok PIR Insulation boards to create an effective system for condensation control. Proper installation sealing all joints and laps is critical.

Installation

Mannok PIR Insulation Boards come in standard sizes to suit typical construction applications. They can be easily cut with a knife or saw. The boards are installed using mechanical fixings appropriate for the application.

For optimal thermal performance, care must be taken to minimise air gaps, seal joints, and avoid thermal bridging. Vapour control layers or membranes are used to manage moisture and avoid interstitial condensation.

Mannok provides comprehensive installation guidelines for all applications.

Accreditation

Mannok PIR Insulation Boards comply with the relevant UK and European standards:

  • BS EN 13165 Factory made rigid polyurethane foam (PUR) products
  • BS EN 13172 Thermal insulating products - Evaluation of conformity

FAQs

What sizes are Mannok PIR Insulation boards available in?

Mannok PIR Insulation boards come in a range of standard sizes:

  • 1200mm x 2400mm
  • 1200mm x 2438mm
  • 1200mm x 2743mm
  • 600mm x 1200mm
  • 450mm x 1200mm
What facings are available?

The range includes foil, fleece, plasterboard laminate, and plain butt edge facings. Specialist boards are also available for different applications.

How should Mannok PIR Insulation boards be stored?

Boards should be stored flat in a dry, covered area. Avoid storing in direct sunlight. Stack boards on battens if storing outside and cover with tarpaulin.

How should boards be handled on site?

Handle boards carefully to avoid damage, particularly to edges and corners. Boards can be cut with a knife or fine tooth saw. Do not stand on or use boards as a work platform unless fully supported.

How are Mannok PIR Insulation boards fixed?

Mechanical fixings are used appropriate for the application. This may include nails, screws, wall ties, clips, battens etc. Ensure fixings minimize thermal bridging.

What about fire performance?

Mannok PIR Insulation boards meet the required fire ratings for building insulation. Check product literature for Euroclass ratings.

Can Mannok PIR Insulation boards get wet?

Avoid exposure to moisture during storage and installation. Boards are not suitable for use below the damp proof course. Protect installed boards from weather until the cladding is complete.

Is planning permission needed?

Planning permission may be required for certain external applications. Always check with local regulations.

What about building regulations?

Mannok PIR Insulation boards enable compliance with UK building regulations for conservation of fuel and power. Ensure regulations are met in system design.

How are thermal bridging and air gaps avoided?

Careful detailing of junctions, continuous insulation, and proper installation helps minimize thermal bridging and air gaps. Airtight taping of board joints is also important.

What maintenance is required after installation?

Mannok PIR Insulation boards do not require regular maintenance. Boards are durable with long service life if correctly installed.

Can Mannok PIR Insulation boards be used with underfloor heating?

Yes, Mannok Therm Floor MF boards are suitable for use with underfloor heating systems. Ensure proper detailing to conduits.

How environmentally friendly are Mannok PIR Insulation boards?

The boards have low global warming potential and zero ozone depletion potential. Mannok operates an Environmental Management System certified to ISO 14001.

What accreditations do Mannok PIR Insulation boards have?

Boards are CE marked and hold BBA, NSAI Agrement and LPCB approval. Mannok's quality system is certified to ISO 9001.
