Recycled words that keep you warm

Warmcel100, from ecological building product specialist Natural Building Technologies (NBT), is a loose fill cellulose fibre insulation made from recycled newsprint.

Warmcel100, from ecological building product specialist Natural Building Technologies (NBT), is a loose fill cellulose fibre insulation made from recycled newsprint.

At 0.035 Wm/K it offers over 12% greater thermal performance than conventional insulation - as well as having numerous other benefits.

The insulation is environmentally friendly, non-itchy and non-toxic, yet it is highly durable, it actively assists in the control of moisture - drawing vapour away from vulnerable timbers without any loss of thermal performance.

This is particularly important in older buildings.

By contrast mineral fibre insulations rapidly lose their thermal qualities when damp.

According to the BRE (Building Research Establishment) "A disproportionate amount of heat is lost through the smallest of gaps" - and this is exactly one of the problems that is eliminated with this insulation.

NBT's Warmcel 100 is supplied ready for use in 8 Kg bags (enough to cover 2.5m2 at 100 mm thick) is treated against fire and, being loose fill, is quick to install and always fits properly.

Poor fitting of quilt type insulation is commonplace, especially where access is restricted such as in shallow pitch roofs or around trusses.

Warmcel can even be used in `top-up' situations where it fills any gaps in the existing insulation before adding the new layer on top.
