Get to know your optionsWhat is the difference between rockwool and glasswool?+
Rockwool is made from rock fibres; glasswool is made from glass fibres. Both are used for thermal and acoustic insulation. The suitable choice depends on the application, thickness, density and complete building system. Share your requirements so we can discuss your options.
Which rockwool brands do you supply?+
We supply ROXUL / ROCKWOOL and Rockinsul. Our range includes ROCKWOOL Safe ’n’ Silent Pro 331 slabs and Cool ’n’ Comfort RL930(48).FF rolls. Please contact us for current stock and available specifications.
Will acoustic panels soundproof my room?+
Fabric wrapped acoustic panels absorb sound within a room to help reduce echo and reverberation. Preventing sound from travelling between rooms involves the walls, doors, windows and other parts of the building. Tell us which problem you want to address before selecting materials.
How do I get a price for my project?+
Call or WhatsApp 077 735 6156, or email sales@diyalumainsulation.com. Send the product, required thickness and density if known, area or quantity, and your project location. We’ll confirm the options and pricing directly.
