Cavity Closers Wall Insulation

Safe-R Close-R

Wall Insulation

Structural failures in cavity walls are often due to the incorrect placement of wall ties within the cavity. Openings at windows and doors require additional wall ties to be placed at a maximum 225mm into the cavity at every course of block. It is also a requirement under AD Part A that additional wall ties must be placed at gable end openings and either side of expansion joints.

These extra structural ties interrupt the continuity of the insulation layer and increase Thermal Bridging issues at very vulnerable
areas, with mould growth normally most evident at reveals.

Safe-R Close-R achieves a fire rating and allows for the correct placement of wall ties to meet AD Part A structural requirements. The insulation performance helps attain Passive and Future Homes Standards for Thermal Bridging.

FAQs

What Insulation is the Safe-R Close-R Cavity closer?

The Safe R Close R range is manufactured using phenolic insulation and stone wool. The phenolic foam is a rigid, lightweight material made from phenolic resin with a closed cell structure. The stone wool provides a compressible layer that allows wall ties to be embedded and ensures a seamless fit with the selected wall insulation system.

How does Phenolic Insulation work?

Phenolic Insulation works by reducing the transfer of heat through a building’s wall, roof, floors and other structural components.

The lower the thermal conductivity in the phenolic insulation, the higher its insulating capacity.

Heat conduction and lambda value

As it has a low thermal conductivity it is difficult for heat to pass through it, which makes it is such a good insulator.

R-Value

A low lambda value (Thermal conductivity) results in a high R-value or thermal resistance, a measure by which we assess specific insulation products in relation to their insulation thickness. This thermal resistance quantifies the area and temperature difference needed to transfer 1W of heat energy. The higher the R- value, the lower the amount of heat loss.

The low lambda value of Phenolic means that anyone working with the product can insulate a building comfortably thanks to its thickness while optimising the energy performance. With Phenolic, you can make the most efficient use of the space available to you. Since you need less insulation material overall, this is the definition of a smart investment.

What is an Insulated Cavity Closer?

Unilin Close-R fully insulated cavity closers are a solution for builders and specifiers for the closing of cavities around window and door openings, preventing cold bridging, damp penetration, air infiltration and condensation.

Where can you use Insulated Cavity Closers?

The Close-R range is used to close cavities and is suited to all types of windows and doors and is available in sizes to fit cavity widths from 100mm – 150mm, with checked detail to suit brick or drylined specifications and flanged detail to suit block outer facings. (Flanged detailing requires precise construction tolerances).

You can always create an insulated system with PIR. PIR insulation has a low thermal conductivity, delivering enhanced thermal performance and allowing significantly thinner installations compared with alternative insulation materials such as mineral wool
