External Timber Finishes

Tuesday, July 12, 2022

Colourless coatings on external timber elements, whilst very fashionable, only provide limited and short-lived protection from UV radiation in the Australian sun. As skin must be protected from UV radiation with sunscreen, timber too must be protected from UV attack by pigments in the protective coatings used.The basics of how UV degradation occursUV radiation permanently destroys all organic substances. This includes wood even it has been varnished with a colourless coating that has no UV protection. UV radiation destroys the lignin within the wood structure. Lignin constitutes about one third of the timber structure but also accounts for 80-95% of

COLD? Prepare your home for next winter

Thursday, July 07, 2022

Temperatures are plummeting and heating costs are rising. Many Australians feel cold and uncomfortable in their homes due to poor thermal performance of the building. Insulation and airtightness are key.NatHERS star ratingHouses are given energy star ratings by the Nationwide House Energy Rating Scheme (NatHERS) from 0 (lowest) to 10 stars (highest) with the minimum performance of 6 stars for new homes built now. Unfortunately, the average home only reaches 1.8 stars. Insulation of the whole building envelope will improve this rating: underfloor, ceiling and wall insulation together with double or triple glazed windows make the house more comfortable and
Calculate your Heat Loss

Calculate your Heat Loss

Monday, June 06, 2022

Heating (and in warm climates, cooling) are a large part of energy use, and this can be reduced dramatically by installing energy efficient windows and doors which will decrease energy costs and greenhouse gas emissions. yourhome.gov.au writes that 'Up to 87% of a home’s heating energy can be gained and up to 40% lost through windows' and provides the following calculations: The amount of heat conducted through a glazed unit (in watts; W) is calculated as Uw × T × A: the U value (Uw) multiplied by the number of degrees difference in air temperature on each side (T) multiplied

Invite natural light into your home

Invite natural light into your home

Monday, May 30, 2022

The trend in residential architecture is for ever larger glazed areas to provide a connection to the outdoors and invite natural light into the house. Unfortunately, around 70% of homes are still built with single glazed windows and doors. Considering that over 80% of heat is gained and 40% is lost through windows it makes sense to choose double or triple glazed windows.High performance windows are the key to increase the amount of natural light into your home and enable all aspects of comfort: very little heat loss or gain, no drafts, no noise and increased security.With double or triple

Wednesday, April 06, 2022

A recent visit to one of the very first Paarhammer window clients confirmed that all their double-glazed windows and doors are working perfectly well after more than 30 years of daily use. “We are still so very pleased that we chose Paarhammer to make our windows and doors when building our home in the early 1990’s, and we still enjoy the benefits of high comfort and low energy use more than 30 years later.” Real sustainability is longevity of materials.TimbersIn these early years windows were made from Oregon timber but as Paarhammer was looking to use Australian raw materials, that
Why is airtightness so important?

Why is airtightness so important?

Friday, March 18, 2022

The size of an average Australian house is 250m2 – or about 625m3 of volume - and most homes require heating or cooling for a large part of the year. If the building is not airtight – meaning if there are draughts – the home requires a fortune on energy costs just to keep it feeling comfortable. Why? Air leakage is defined as uncontrolled flow of air in and out of a building due to pressure differences across the building envelope. This means that the air of an average Australian home is unintentionally exchanged between the inside and the outside

International Year of Glass: 2022

Monday, February 07, 2022

Glass is a major part of window and door products and of our daily work here at Paarhammer. But with its unparalleled versatility and technical capabilities, glass provides so much more to our society like glass optical fibers, containers for life-saving medicine, optical glasses, support of solar cells, glass fibre, glass art and so much more. Therefore, the United Nations has decreed the year 2022 to be the Year of Glass. As window makers, we require glass in sheets, first flat glass was used and later float glass. The float glass process was invented by Sir Alastair Pilkington in 1952
