Improving thermal performance with secondary glazing

environmental level, but also economically. Secondary glazing is a well-established method of greatly improving insulation within existing buildings. As the leading specialist in secondary


glazing, Selectaglaze has a range of tested products that can reduce the U-value of a building to around 1.8 when coated in low emissivity glass. With the Pilkington Spaica glass in the S25 unit, it can be reduced down even further to around 0.8. All units are designed and expertly installed with brush seals, or compression seals for hinged panels, to ensure the tightest fit, dramatically reducing air infiltration to help eliminate uncomfortable drafts. Built at the start of the 19th

space with the assistance of Selectaglaze secondary glazing. All of the original leaded light windows

Century, a

striking Grade II Listed entrance lodge located in Beaconsfield, Buckinghamshire, has morphed into a comfortable living

offered poor insulation and were unable to retain heat efficiently. To improve the insulation, a bespoke and sympathetic solution was required which would not detract from the historic features, so the Estate Manager contacted Selectaglaze, the UK’s leading designer of secondary glazing, to provide a solution for the thermal inefficiencies. Selectaglaze installed six units from its

Half hour test success for SWA

A painstaking programme of development and testing, conducted by the Steel Window Association’s technical committee, has led to the UK’s top-rated fire testing centre granting a half-hour test certificate for both single and double W20 doorsets. Ongoing work by SWA member companies has culminated in the full fire test, resulting in a 30-0 rating. This now means that installations of single or double

doorsets as part of full internal steel screens can be carried out in full compliance with building regulations; but will only be available through companies belonging to the SWA. It’s a wrap for Bostik at museum

Bostik’s self-adhesive thermal acoustic wrap, W110, has been used to provide acoustic insulation on the plastic rainwater and soil pipe system at the newly refurbished Brecknock Museum in Brecon, Wales. The main contractor for the HVAC work on the museum project, selected Bostik W110 as it’s up to 20 per cent quicker to install than traditional acoustic insulation products, allowing them to

save valuable time during the restoration. Supplied on a compact and lightweight roll, Bostik W110 forms an instant bond around pipework with no need for the extra banding or clips.

eing more thermally efficient and wasting less energy has become very important, not only on an

Series 10 range and one Series 45 single side hung casement. Both ranges are slimline solutions ideal for heritage projects, as they introduce minimal sightlines and are designed to be as unobtrusive as possible. This, along with high performance seals, helped to virtually eliminate unwanted draughts and provide a more comfortable living space for the tenants. The inclusion of a low emissivity hard coating on the laminate glass reduces the U-value of the window combination to between 1.7 to 1.9 W/m2

K. The new tenants of the lodge are pleased

with the general look of the secondary glazing, the heat retention in the property and also remarked that they generally use less energy, which has led to lower bills. Established in 1966 and a Royal Warrant

holder since 2004, Selectaglaze has vast experience in working with all types of buildings throughout the UK.

01727 837271 Fit for purpose?

A specification validation service has been developed to help ensure the practical and aesthetic longevity of screening louvres. Gilberts Blackpool has developed the service to enable specifiers to be assured, from the outset, that the material, finish and format of the louvres will deliver, within budget. Gilberts has developed its own louvre product range over the years to provide a comprehensive package to keep pace

with the evolution of building design and structural interfaces, initially and as/if the building structure is altered.

01253 766911 OPTIM-R supports growth of museum

The Kingspan OPTIM-R Roofing System has provided a slim, lightweight and highly thermally efficient solution for the Phase II extension of the prestigious Garden Museum in London. Alun Jones, Partner at Dow Jones Architects, explained: “We normally use Kingspan Insulation and we

were particularly interested in the super thin OPTIM-R vacuum insulation panels (VIPs) as they would allow us to keep the overall thickness and weight of the roof as low as possible without having to reduce the thermal performance of the layer.”
