Loft insulation is an effective way to improve the energy efficiency of a home, reduce heating costs, and make the home more comfortable. Here are some of the key benefits of loft insulation for customers: 

Energy Savings: Loft insulation helps to prevent heat from escaping through the roof of the home, which can significantly reduce heating costs. Studies have shown that loft insulation can save homeowners up to 25% on their energy bills.

Environmental Benefits: By reducing energy consumption, loft insulation also helps to reduce greenhouse gas emissions and make the home more environmentally friendly.

Increased Comfort: Loft insulation helps to keep the home warmer in the winter and cooler in the summer, making it more comfortable to live in all year round.

Improved Indoor Air Quality: Loft insulation can also help to reduce the amount of condensation and dampness in the home, which can improve indoor air quality and reduce the risk of mould and mildew.

Long-Term Investment: Loft insulation is a long-term investment in the home, as it can last for many years and continue to provide benefits over time.

Quick and Easy Installation: Loft insulation can be installed quickly and easily by a professional installer, with minimal disruption to the homeowner.

Overall, loft insulation is a cost-effective and efficient way for homeowners to improve the energy efficiency and comfort of their home while also reducing their environmental impact.

What are the different types of loft insulation?

Mineral wool insulation: Mineral wool insulation, also known as rock wool or slag wool insulation, is made from natural or recycled materials and is a popular choice for loft insulation. Benefits of mineral wool insulation include its excellent thermal performance, sound insulation, and fire resistance. It is also relatively affordable and easy to install. However, mineral wool insulation can be irritant to skin, eyes and respiratory system, and may require protective gear to be worn during installation. 

Cellulose insulation: Cellulose insulation is made from recycled paper and is treated with chemicals to make it fire-resistant. Benefits of cellulose insulation include its excellent thermal performance, sound insulation, and environmental sustainability. It is also relatively affordable and easy to install. However, it can be more expensive than other types of insulation and may require professional installation.

Sheep wool insulation: Sheep wool insulation is a natural and sustainable option for loft insulation. Benefits of sheep wool insulation include its excellent thermal performance, sound insulation, and moisture-wicking properties. It is also non-irritant and easy to install. However, it can be more expensive than other types of insulation and may require professional installation.

Overall, the choice of insulation type will depend on factors such as your budget, environmental preferences, and specific insulation needs.

External wall insulation was done on my house, and I couldn’t ask for a better company to do it. Very good finish, also you can always speak to them if there’s anything you might need . Very happy with our insulation, and I would definitely recommend this company to anyone. The job in this house it was big, but they managed to do everything perfectly fine.
Managers are very easy to speak with.

INSUL8 installed external wall insulation on our house. We found them to be very professional and reliable, keeping us informed throughout the project. I feel they went out of their way to ensure that they did a good job and that we were happy with the work. Our property has been totally transformed and our energy costs will be significantly reduced as a result of the insulation. I wouldn't hesitate in recommending INSUL8.

Fantastic service from Matt and James at Insul8. Very transparent, honest advice. Talked us out of a more expensive solution that would not have been appropriate! Happy to give advice on any energy saving work, even if its something we will be doing ourselves in future. Excellent service from initial call to estimation visit to final installation of the loft insulation, cannot recommend them highly enough.

Neil, Nottinghamshire

Have been very pleased so far with Insul8. It took me some months to make a decision but they have worked with me and I am so pleased I did because they sent a team who have cared about the work they have done as if it were Buckingham Palace. My main contact throughout has been James Hancock and he has kept me well informed. It has been a real pleasure dealing with a company with integrity. Thank you all so much
