Flat Roofs

Whether it is a cold or a warm deck roof, Low-E can reduce thickness, thermal bridging and condensation risk. Low-E Insulation can be installed above or below the joists quickly and easily to create a warmer more efficient roofing system.

Quick and Easy to Install

Occupies Less Space

No Layer, No Dragging on Screws

Reduces Condensation Risk

Stops Draughts

A flat roof is usually designed with ventilated air spaces below the timber deck. These ventilated air spaces are necessary for the structure, but often create draughts within the building. Installing Low-E Insulation below the roof can reduce the amount of insulation required between the joists, where space may be limited, and can stops draughts coming into the building itself.

“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.”

Flat Roof – Partial Fill

Flat roofs are designed with ventilated air spaces below the timber deck. These ventilated air spaces are necessary for the structure, but often create draughts within the building. Installing Low-E® EZY below the roof can reduce the amount of insulation required between the joists and stops draughting within the building itself. This example shows Low-E® EZY installed with a rigid foam between the joists before the finished ceiling is installed.

Flat Roof – Full Fill

When installing a Mineral Fibre between joists, it is not very easy to maintain air spaces on both sides of Low-E®. In this example, Low-E® has been installed with a full fill of Mineral Fibre between the joists and Low-E® EZY installed below the joists before being counter battened, and the finished ceiling is installed.
