44 BUILDING FABRIC
Laminated glazing is made with two plies of glass bonded together with interlayers, making it shatterproof meaning the home is safer and securer. Toughened glass is often used on the external pane of security roof windows. This glass is much harder to break. If it does shatter, it breaks into larger, more blunt pieces that are safer than ‘standard’ glass shards.
GET THE RIGHT GAS
When it comes to window glazing, ensure your double or triple glazed windows have cavities fi lled with either argon or krypton gas. Argon is a form of inert gas meaning it doesn’t undergo a chemical reaction when conditions such as temperature change. The thermal conductivity of Argon is 33% better than air.
Argon gas is an inexpensive option so will keep the cost down while still providing good thermal insulation. But If you’re looking for a highly
effi cient window, look for one that uses krypton as the cavity gas. Krypton is even more effective than argon, and thus more expensive. The insulative effect of krypton is 40% better than argon and 65% better than air.
Either gas will help to keep energy bills down and reduce CO2
emissions.
Regulations but the best have a value of 0.5 W/m2
K. SHUT OUT THE NOISE
Thick curtains can help to reduce road noise in a home, look out for ones specifi cally designed to reduce sound. When trying to reduce noise in an attic room, you’ll need to look into roof window blinds for your pitched windows (curtains obviously won’t cut it). Blinds are limited in how much sound they can reduce, but a shutter is much more effective.
KNOW YOUR ENERGY RATINGS The most commonly used window glazing energy rating is U-value. U-value defi nes how much heat is lost through the glazing, sometimes known as the heat transfer coeffi cient, or thermal transmittance coeffi cient. he lower the -value, the more energy effi cient a window is.
Ug is the U-value of the pane
specifi cally. w is the -value of the window as a whole. A U-value of 1.4 W/m²K is required by Building
hutters created specifi cally for roof windows provide a much more robust roof window cover that will make a noticeable noise difference in the home. Shutters also add high-quality protection – as well as thermal insulation – to the roof window. They cover over the external side of the window so potential intruders can’t access any part of the window itself.
CHOOSE ECO-FRIENDLY
Look for the most eco-friendly roof window on the UK market and you will fi nd a product thats likely to also be safe, secure and noise-reducing as it features all of these benefi ts.

Hardie® Architectural Panel chosen for Go Modular project B
eam Contracting, the high-end construction fi rm, has chosen to utilise the Hardie® Architectural Panel, a product
from James Hardie, the world leader in the manufacture of high-performance fi bre cement and fi bre gypsum building solutions, as part of its construction of ten modular fl ats in Poole in conjunction with Go Modular Technologies (UK) Ltd, the modular building manufacturer. The decision to choose the Hardie®
Architectural Panel was based on the fact that it is easy to install and delivers a cost eff ective, low maintenance solution with the assurance of an A2 fi re rated performance. Vivalda, the independent distributor of cladding panels, supplied the materials for the project, fabricating the panels in phases to coincide with the construction schedule. Smooth sand, one of the available textures, was chosen to match the planning specifi cation in three of the core panel colours (Arctic White, Anthracite Grey and Cobblestone), giving the project a modern and contemporary look, and refl ecting the coastal location. Steve Hawes, project director at Beam
Contracting commented: “This was the fi rst time that we’ve used the Hardie® Architectural Panel and we were really pleased with how easy it was to install - so much so that we have subsequently added the panel as a standard specifi cation option for Beam Contracting.” Lee Bucknall, UK sales manager at James
Hardie, added: “Modular buildings are becoming
an increasingly popular solution providing construction fi rms and clients with lower project costs, sustainability benefi ts and signifi cantly reduced build times. Hardie® Architectural Panel is perfectly suited to supporting modular
