Glass Matters

Glass Matters

Monday, October 14, 2013

Glass is an important factor for the performance of windows and doors. Here are some terms and explanations and how glass can be used: Annealed Glass: the common flat glass often used in double glazing. It tends to break into large jagged shards. Toughened Glass: annealed glass is heated to above 600 °C and the surface then rapidly cooled, resulting in increased resistance to breakage. If it does break it breaks into small regular, mostly square fragments. Laminated glass: this is made of two or more layers of glass with an interlayer bonded in between, providing safety and security. In

U-value of 0.8

Thursday, September 05, 2013

Hot off the press! The latest energy efficiency test for Paarhammer achieved a very low 0.8 U-value. Testing is performed for the whole window system which includes the frame, glass, seals and spacers. All components make a difference to the energy used in your home. A lower U-value number indicates better energy efficiency. Tested by Ian Bennie & Associates, an Australian Fenestration Rating Council - AFRC – accredited organisation, the results are: PAR-009 Fir Timber Fixed Window rated with SuperSpacer – TG ID Name Glazing Name Glazing ID Uw SHGCw Tvisw 2 PAR-009-001-01-4-12Ar-3-12Ar-4 4-12Ar-3-12Ar-4 10400 1.7 0.52 0.56 3 PAR-009-002-01-4PThrm-12Ar-3PThrm-12Ar-4PThrm

When you talk about the energy efficiency of windows, it is not just the glass but the whole window system, which includes the frame, glass, seals and spacers. All components make a difference to the energy used in your home. Tested window products receive a rating called the U-value. A lower number indicates more energy efficiency. The U-value can be as high as 7.5 in some windows and doors and as low as 0.8 for extremely energy efficient products (0.8 is Paarhammer’s latest and best rating). The testing of energy efficiency must be performed by a rating organisation which is
Renovations on the Rise

Renovations on the Rise

Monday, June 24, 2013

Australia's love affair with renovating is expected to continue with property equity levels beginning to improve. In Victoria, current levels of housing starts remain higher than anywhere else and renovation investments are at record levels. The latest figures from the Australian Bureau of Statistics (ABS) reveal that in 2012 building approvals for home renovations totalled $6.35 billion or around $500 million every month. This trend of growing renovations is likely to continue not only because Australians love to renovate, but also as households increasingly prefer to direct excessive property transaction costs towards improving their existing homes, rather than trading up.

The Building Designers Association of Victoria's now famous 10-Star Challenge is in it's third year. Ambassador this year is James O'Loughlin of 'The New Inventors' fame who officially launched the Challenge on Wednesday night. Paarhammer is a proud sponsor. The 10-Star Challenge is for conceptual projects that combine admirable architecture with energy efficient planning solutions and materials utilisation. There is increased interest and commitment by consumers to reducing their carbon footprint and minimise ever-increasing energy bills. The campaign helps the design community to focus on the benefits of sustainable design for dwellings. Last years winner of the 10-Star Challenge for
Life Cycle Analysis - LCA

Life Cycle Analysis - LCA

Thursday, March 07, 2013

What is LCA? Life cycle analysis or LCA is a method of measuring the environmental impacts of building products over their whole life. The aim of a life cycle analysis is to identify, quantify and assess the impact of the energy and materials used and wastes released to the environment throughout the life of a building product. There are many life cycle analysis methodologies and all vary in their range and complexity but it all comes back to sustainability. The life cycle analysis of timber follows the piece of wood from harvesting, manufacture, construction and product life to recycling and
Sustainability - Carbon Store

Sustainability - Carbon Store

Friday, March 01, 2013

Growing trees absorb carbon dioxide from the atmosphere, emit oxygen and store carbon. About half the dry weight of a tree or wood product is carbon; one ton of carbon represents 3.67 tonnes of carbon dioxide. Australia's native forests, timber plantations and wood products are all net absorbers of greenhouse gases. In 2005, they sequestered (or stored) 56.5 million tonnes of carbon dioxide, reducing Australia's overall greenhouse gas emissions by almost 10%. The combination of carbon sequestration in growing trees and the long term carbon storage in wood products represents a significant net sink and store of carbon for Australia.
Are your windows child safe?

Are your windows child safe?

Tuesday, February 19, 2013

The Children’s Hospital at Westmead in NSW reported that from 1998 to 2011 there have been 113 young children admitted after falling from windows. To reduce such incidents the National Construction Code now requires window barriers to openable windows where the sill is less than 1.7m above floor level and the floor below the window is more than 2m above the surface beneath, effective from May 2013. These new rules apply for all windows in early childhood centres and in habitable rooms in residential buildings. Windows are to be either fitted with a screen or have the window opening limited
