Investing in a higher R-value will help protect you from the burden of increasing energy prices.\u003c\/p\u003e\u003ch2\u003eR1.5 Insulation Batts – Choosing Brands\u003c\/h2\u003e\u003cp\u003eWhen choosing the right brand for you the most important factor is to consider the products R-value and other properties such as acoustic and thermal performances. The higher the R-value, the better the resistance to heat flow and the greater the energy savings. For your thermal benefit we recommend upgrading from R1.5 insulation to R2.0 or R2.5 for your wall insulation. This will lead to higher energy savings.\u003c\/p\u003e\u003ch3\u003eR1.5 Batt Insulation For Walls\u003c\/h3\u003e\u003cp\u003eIn cooler climates a higher R-value is generally recommend, even if your energy report requires a minimum of R1.5 wall insulation. If you are recladding or replastering your home during renovations, you should consider installing \u003ca href=\"\/collections\/acoustic-insulation\"\u003eacoustic insulation\u003c\/a\u003e in your walls. This will help to reduce noise and create a more comfortable home to live in. The key is not to leave gaps, as this will greatly reduce the effectiveness of the insulation. Insulation companies in Australia have adopted two main standard widths of R1.5 insulation, 430mm wide and 580mm wide. This is because the timber frames in most Australian homes are spaced at either 450mm or 600mm ‘centres’ – from the centre of one timber to the next. Assuming the house framing is spaced at either of these two dimensions, when installed your insulation will fit snugly between the joists or studs. However not all houses are built to this standard and this creates extra work for insulation installers.

The length of each batt is 1160mm, so cutting it in half will give you two pieces, 430mm high x 580mm wide. \u003c\/div\u003e\u003cdiv class=\"pw-cmedia\" style=\"display:grid;grid-template-columns:repeat(auto-fit,minmax(220px,1fr));gap:14px;margin:22px 0;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1073\/8070\/3564\/files\/buy-knauf-earthwool-glasswool-wall-insulation-batts-2.jpg?v=1788257365\" alt=\"buy knauf earthwool glasswool wall insulation batts 2\" loading=\"lazy\" style=\"width:100%;border-radius:10px;display:block;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1073\/8070\/3564\/files\/buy-pink-batts-insulation-online-2.jpg?v=1788257363\" alt=\"buy pink batts insulation online 2\" loading=\"lazy\" style=\"width:100%;border-radius:10px;display:block;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1073\/8070\/3564\/files\/buy-bradford-gold-wall-insulation-batts.jpg?v=1788257365\" alt=\"buy bradford gold wall insulation batts\" loading=\"lazy\" style=\"width:100%;border-radius:10px;display:block;\"\u003e\n\u003c\/div\u003e\u003cdiv style=\"position:relative;padding-bottom:56.25%;height:0;margin:18px 0;border-radius:12px;overflow:hidden;\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/VPY3i-xnhV0\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;\" loading=\"lazy\" allowfullscreen=\"\" title=\"Wall Insulation - What R-Value Should I Install?\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e","products":[],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1073\/8070\/3564\/collections\/buy-r1-5-insulation-batts-online-wall-batts.jpg?v=1784022136","url":"https:\/\/pricewiseinsulation.com.au\/collections\/r1-5-wall-insulation.oembed","provider":"Pricewise Insulation","version":"1.0","type":"link"}
