ThermaEdge is part of the Alreflex group of products; it is a bubble foil insulation designed to prevent cold bridging at the junction between floor slab and cavity wall. It has a foil coating to one face and a flattened top edge that allows the product to be built into the mortar course or fixed to the sole plate.Product Benefits:
- Thin and flexible.
- Fast and simple installation.
- Zero GWP and ODP.
Width – 525mm
Length – 50m
Thickness – 3mm
Alreflex ThermaEdge is designed to insulate the edge of a floor slab in cavity wall and timber frame constructions and can be dressed down the cavity to insulate trench blocks. This product can be built into the mortar course of masonry or be mechanically fixed to the sole plate of timber frame constructions.
As a flexible insulation Alreflex ThermaEdge is simple to install in complex detailing areas and in curved structures, where it is not practical to use rigid board type insulations.
Cold bridging is the term used to describe an area of a buildings envelope where a product (or products) with poor insulating properties passes through the external element. This creates a path of low thermal resistance allowing cold external temperatures to be transferred through the construction, reducing the temperature of internal surfaces. This creates a high risk of condensation forming on these cold areas.
The correct design of these areas can reduce and eliminate cold bridges and their associated problems. The evolution of UK building regulations in recent years has seen an attempted to do this by implementing minimum design criteria in areas that are most susceptible to cold bridging.
Methods of complying with these minimum requirements are catalogued in the Accredited Construction Details. Thermal Economics have provided a range of products designed to reduce thermal bridging for over 15 years. These products can achieve and exceed the minimum insulation requirements set out in the Accredited Construction Details and are ideally suited to common cold bridge areas that are not covered in the Accredited Construction Details, such as steel work in cavities, wind posts and at the edge of ground bearing slabs.
