Quinn Therm

quinn therm insulation

Quinn Therm Insulation is a high performance, fibre free board, with a rigid thermoset insulation core and faced on both sides with a low emissivity composite foil facing.

The low emissivity foil facings increase the thermal resistance an unventilated cavity adjacent to the insulation, reducing the overall U-value of the wall.

The good dimensional tolerances of the Quinn Therm QW PIR Insulation board enable it to be tightly butted to form a continuous layer of insulation.  Joints can then be easily taped with an aluminium foil tape to provide an effective vapour control layer.

Wall Climaflex

Ideal for a range of applications, Climaflex is low cost, energy efficient and easy to work with. It is made from flexible polyethylene foam which can easily be worked around tight corners and in confined spaces. It is most commonly used to insulate centeral heating pipework and as pipe insulation in loft spaces to prevent freezing and also in areas prone to drafts such as under the floor or below windows. 

Because of its low thermal conductivity, Climaflex reduces the loss of heat from distributors in plumbing and heating installations by up to 80%. This maximizes not only the cost efficiency, but also the ecological efficiency of the entire unit. 
Climaflex also reduces pop and flow noises in pipes thanks to it's sound absorption properties

Polystyrene Sheets
