Church benefits from airtight membrane
Wraptite-SA airtight membrane has demonstrated its outstanding flexibility to offer high
performance protection to the building envelope, in the restoration of a historic church building
which was damaged by the earthquake which hit Japan in 2011.
The Tokyo Wakaba Christ Church’s arched windows are a key feature, and presented a challenge
when specifying a suitable water resistant membrane, which was flexible, yet resilient to resist
punctures and tears, and provide high performance protection for the building. Wraptite-SA was
perfectly suited to work around the window arches, achieving full water protection.
Wraptite-SA is a self-adhering, airtight, yet vapour-permeable barrier, which is fully water resistant
and was applied externally to the walls and the windows. The self-adhesive benefits of Wraptite-SA
removed any risk of failure through leakage, as compared with membranes requiring mechanical fixing
with staples.
Wraptite Tape was used on the installation to complement Wraptite-SA in dealing with the more
intricate detailing around areas such as the windows, doors and penetrations.

Panel in demand
Panel Systems, one of the UK’s leading
manufacturers of insulated panels, has
reported a major increase in demand for
Styrofloor, a high performance insulation
solution for enhancing the energy efficiency
of conservatories and extensions.
Styrofloor is an easy-to-fit insulated flooring
panel that is suitable for use in new build
and refurbishment projects. This innovative
flooring solution reduces the amount of
heat that is lost through the floor, providing
effective insulation than can achieve U-
values as low as 0.11 W/m-K.
Styrofloor boards are made from Styrofoam
extruded polystyrene (XPS) insulation, which
are bonded to a moisture resistant
chipboard finish. The chipboard incorporates
a tongue and groove detail on all four edges
for ease of installation. Because Styrofoam
offers closed cell insulation, the boards
provide good water resistance - this
eliminates the need for a vapour control
layer in the floor construction.
Styrofloor can be delivered directly to site
on pallets, or collected from Panel Systems’
conveniently located warehouse just off
junction 31 of the M1. Technical information
on performance detail and installation
methods can be found at the website.

Kingspan rises to the challenge
Products from Kingspan Insulation’s Kooltherm and Therma ranges
have helped to transform a derelict water tower in North Yorkshire
into a striking family home, as featured on Channel 4’s Restoration
Man. Whilst ceiling height wasn’t an issue in the 46’ tower, the
narrowness of its footprint meant that the width of the walls
needed to be kept to a minimum in order to maximise the liveable
space. This led to the specification of Kingspan Kooltherm K12
Framing Board.
Timber studwork was installed on the inner face of the brick
external walls, with 50mm thick Kingspan Kooltherm K12 Framing
Board installed between the battens. The insulation boards offered
a lightweight solution which could easily be cut to size.
To insulate the cavity walled construction of the low-level
extension, 50mm Kingspan Kooltherm K8 Cavity Board was installed. Both products offer premium
levels of thermal performance with thermal conductivities as low as 0.020 W/m.K. The boards
have been assigned the highest possible 2008 Green Guide Summary Rating of A+ by the BRE, and
are manufactured under a management system certified to ISO 14001: 2004.
Underfloor heating was installed on every floor of the building; to help retain the heat in the floor
space above, Kingspan Thermafloor TF70 floor insulation was installed beneath the heating pipes
on every floor.

FAKRO low profile roof windows used to enhance
visual aesthetic
Phase one of the restoration and
extension of the Larbert House
and Country Estate near Falkirk has
seen the former stables converted
using 46 FAKRO conservation style
roof windows.
Top hung and pivot FAKRO FPP-
V/C U3 windows with ELJ/C
flashings were used so that they
could be positioned low within the
natural slate roofline. This enhances
the visual aesthetic of the
Georgian sandstone buildings, while giving home owners scope to switch opening from centre
pivot to top hung simply by the use of a switch in the frame.
