The Loft Lid downlight cover eliminates heat loss and air leakage
into the loft space. It creates an air tight seal around downlights
and allows a continuous layer of insulation to be safely laid over
the top to comply with current building regulations. The Loft Lid
is designed and manufactured in the UK and has been tested to
EN60695 and EN60598 by the UK Lighting
Industry Association.

Alternative insulation materials –
polyurethane foam for better insulation
Polyurethane foam can be used as a high
performing insulant for all types of new build
or refurbishment project to meet or exceed
today’s standards. It is also widely used by
architects and specifiers for remodelling
purposes, for instance in barn conversions.
When used for airtightness or stabilisation
under the roof or within the cavity it
outperforms most other materials. It is particularly cost-effective and easy to
apply to a wide variety of substrates. Its
closed-cell nature renders it very resistant
to moisture ingress and grades are available
which achieve both Class 1 and Class 0 fire
ratings when tested to BS 476 Part 7 and
6 respectively. The urethane foam can be
applied in any thickness to suit the insulation
requirements of the building.
The sprayed or injected foam is not just an
insulant – it can be used for stabilisation
purposes, for instance to hold tiles in place
for a stronger roof structure or to take the
place of failing cavity wall ties. The material
can often be used when other materials
are simply not suitable. The material is so
versatile that it can be used in many different
situations from buildings to boats! The trade association for the sprayed and
injected polyurethane foam industry is
the British Urethane Foam Contractors
Association. BUFCA is a central resource
for the application of polyurethane foam
systems. The association consists of
polyurethane foam installers operating to
high standards, together with material and
equipment suppliers.
The polyurethane insulant is a two-
component liquid system which produces a
highly-efficient blanket of insulation with
an exceptional thermal conductivity figure. Polyurethane foam can be installed to help
meet Building Regulations as wall insulation,
roof insulation, floor insulation or to fill
voids and other areas providing a seamless,
85
thermal insulation barrier. Other jointed
systems give rise to a potentially weak point,
leading to a significant loss of insulation
value.
The foam also slows the deterioration of
tile/slates by frost. On the underside of the
covering frost damage is eliminated. On the
weather side the frequency of the freezing/
thawing cycle is reduced. Slates and tiles will
be less prone to damage by impact as the
foam distributes the forces.
When choosing a BUFCA registered
installer, architects, builders, and
specifiers can be assured of the highest
standards of quality and service.
