Frequently asked questions
Does loft insulation help a building to comply with government building regulations?
What is the difference between glass wool, rock wool, and PIR insulation?
Glass wool, rock wool, and PIR are different types of insulation with varying properties. Glass wool and rock wool are mineral wools offering good thermal and acoustic performance.
PIR is a rigid foam with superior thermal insulation but typically less soundproofing. The best choice depends on specific project needs. Contact us for technical support.
What is the difference between a warm roof and a cold roof?
Is insulation a sustainable product?
Yes, insulation is a sustainable product. Many insulation materials are made from recycled materials, and insulation helps to reduce energy consumption, lowering carbon emissions.
Does loft and roof insulation help to boost the building EPC?
