H2OFF has a number of warm flat roof insulations
suitable for different waterproofing systems and scenarios, whether
concrete, timber or profiled metal.
Warm roofs are increasingly popular today as we aim to maximize our
living space and the available accommodation in any construction. This
will be the predominant form of pitched roofing construction in New
In addition, a warm roof contributes to increased air tightness,
reducing heat loss caused by uncontrolled air movement.
By moving the insulation to the outside of the
structure, the roof is effectively brought inside, which results in a
warm roof. This eliminates the possibility of condensation forming on
the underside of the roof and eliminates dampness. Because this design
works by conserving heat, no ventilation is required.
H2OFF can quickly and economically convert any cold flat roof to a warm
roof, particularly where problems have been tackled. Where the existing
roof is in satisfactory condition and of a suitable material (e.g.
plywood), the insulation is fixed directly on top. The whole build-up
should then be waterproofed with a high performance roof membrane
system. This ensures that your investment in energy efficiency is
protected and will continue to pay dividends long into the future,
repaying itself many times over.
Roof vs Cold Roof?
A properly specified
warm-deck flat roof will deliver vastly improved energy efficiency over
the traditional cold-deck design, whilst eliminating the risk of
condensation by moving the dew point to the outside of the structure.
The initial investment is quickly offset by reduced heating and cooling
costs and the resultant increase in occupier comfort.
Our applicators carefully seal around penetrations, vents, skylights,
dormer windows and chimneys to ensure a leak-free roof.
