G Taylor, Bolton, UK

“We had a serious problem with damp and mould. Not only did Low-E eliminate the problem but the room is easily to heat too. It was far more noticeable than the cavity wall insulation that caused the problem with the mould”

Wendy R, Stockport, UK

“The Low-E was quick clean and easy to install. It occupied about 1” of space, so the room feels the same size as it was. It used to be too cold to sit in, now it’s easy to heat. I’m over the moon.”

Gerry D, Sunset Building, Luton, UK

“We are managing to meet U-value requirements in smaller studs. Customers love that we can save some floor space and our fitters love that is quick and clean to install.”

G Stone, Stroud, UK

“We use both the vapour and the breathable versions of Low-E Insulation. We’ve tried using other foil insulation products, but they can be time-consuming and difficult to install. Low-E is so easy to work with, we just wouldn’t use anything else.”

Solid Wall (IWI) Insulation Options

Low-e solid wall (IWI) insulation is ideal for insulating your home and is the perfect choice for an easy installation. If you are considering insulating your home please read through the below guides for the type of wall you have in your home. 

Solid Wall – Space Saving

Solid walls can be constructed of stone, brick or block. They can be difficult to upgrade and often a compromise is made between occupied floor space and efficiency achieved. Installing Low-E® EZY Seal with a plasterboard or insulated plasterboard can be the most efficient way of insulating a solid wall. This example uses a single batten and occupies a minimum amount of space. Solid Wall – Space Saving Diagram

Solid Wall – Double Batten

In this example the wall is battened, the Low-E installed and then a counter batten. Doubling battening occupies additional space but also increases the thermal performance. Solid Wall – Double Batten Diagram

Solid Wall – Timber Frame

In this example, timber battens are fixed to the wall with rigid or fibre insulation installed between them. Low-E® EZY Seal is fixed to battens and then a counter battened installed to create a service void. The counter batten occupies additional space but also increases the thermal performance. You can remove this batten to save space if necessary. Solid Wall – Timber Frame Diagram

Solid Wall – Hollow Block

In this example, timber battens are fixed to the hollow block wall with rigid or fibre insulation installed between them. Low-E® EZY Seal is fixed to battens and then a counter battened installed to create a service void. This reduces draughts and provides maximum performance in the least space possible.
