ROOF INSULATION

Roof and ceiling insulation works by creating a continuous thermal barrier that stops heat from escaping in winter and entering in summer. At 1STOPINSULATION, we install premium Earthwool R7 extra-wide insulation batts, which not only fill the spaces between your ceiling joists but also cover the joists themselves

This extra-wide fit eliminates thermal bridging — a common problem in over 95% of other installations where joists and ceiling edges are left exposed. By fully insulating every part of your ceiling space, we maximise the R-value, improve year-round comfort, and deliver the full energy savings you’re paying for.

Quality roof and ceiling insulation can slash your energy bills, improve indoor comfort year-round, reduce greenhouse gas emissions, and increase your home’s value. By preventing up to 35% of heat loss or gain through the roof, insulation keeps your home cooler in summer, warmer in winter, and saves you money for decades.

The Earthwool R7 insulation batts we install are unappetising and unattractive to pests, making them an effective deterrent for rodents and other vermin looking to nest in your roof space. Unlike some organic or loose-fill products, Earthwool contains no food source and will not break down into nesting material. Combined with our full-coverage installation — right to the edges and over joists — we minimise gaps where pests could settle, helping to keep your roof space clean and protected.

The Earthwool R7 insulation batts we install are naturally breathable and moisture-resistant, helping reduce the risk of condensation, mould, and mildew growth in your roof space. By allowing moisture vapour to pass through rather than trapping it, Earthwool helps maintain a healthier roof cavity. Combined with our full-coverage installation — including over joists and right to the ceiling edges — this creates a consistent thermal barrier that minimises cold spots where condensation can form.

 Yes. Installing Earthwool R7 roof and ceiling insulation is one of the most effective ways to reduce your home’s environmental impact. By improving your home’s thermal performance, it reduces the need for heating and cooling, which in turn lowers energy consumption and greenhouse gas emissions.
Earthwool is also made using up to 80% recycled glass, bound with a sustainable, bio-based binder that contains no added formaldehyde. This means you’re choosing a product that’s not only energy-efficient in use but also environmentally responsible in its production.

 For maximum comfort and efficiency, we recommend a comprehensive home insulation package. While Earthwool R7 roof and ceiling insulation delivers the biggest impact by preventing up to 35% of heat loss or gain, adding wall insulation and underfloor insulation can further reduce heating and cooling costs — effectively cocooning your home.
