Insulation Wholesale

Insulation Wholesale: bulk insulation and drylining supplies

Insulation Wholesale is an online retailer that presents itself as a fast-growing operation working alongside leading insulation manufacturers. Its catalogue is aimed at large projects, small businesses, homeowners and private contractors, and the company states that it serves both trade and public customers. Orders are priced with and without VAT, and the site advertises wholesale pricing, trade credit and free delivery over £550.

The range is organised around insulation materials, plasterboard and drylining, external facades and general building materials, with a shop-by-brand section and filters by thickness.

Insulation types and applications

The product catalogue covers several families of insulation, each presented with its own technical characteristics:

• Insulation board: described as one of the most used construction materials, intended for pitched and flat roofs, internal and external walls and floors in domestic and industrial projects. Stocked in thicknesses from 20mm to 150mm, with thermal conductivity of 0.22 k/mK across all thicknesses and high compressive strength.
• Kooltherm K range: the full Kingspan Kooltherm line is offered as a premium-performance insulation described as one of the thinnest and most efficient products available.
• Mineral wool rolls: lightweight rolls with an A1 fire rating (non-combustible and non-flammable), designed for installation between joists; glass mineral wool is breathable and helps reduce condensation risk.
• Mineral wool slabs: made from mineral wool with non-directional fibre orientation and high density, trapping sound waves and damping vibrations; the acoustic slab repels water, is vapour permeable and resists rot and mould, with semi-rigid formats sized for 400mm and 600mm joist spacing.
• Plasterboard: standard, fire-rated, moisture-resistant and acoustic boards intended to improve the final performance of a project.

Beyond these core categories, the catalogue lists PIR and polyisocyanurate boards, polystyrene boards, phenolic and multifoil insulation, pipe insulation and lagging, fire protection and HVAC duct insulation, vapour control layers and insulation tapes. Applications are grouped by floor, wall, loft, roof, soffit and fireproofing.

Plasterboard, drylining and specialist boards

The plasterboard and drylining section includes standard, acoustic, fire-rated, foil-backed, moisture-resistant and tapered-edge boards, alongside branded lines from Knauf, Gypfor, Siniat and British Gypsum. Insulated plasterboard is stocked from Celotex, Recticel, Mannok, Unilin and the Kingspan K118 range.

Specialist building boards include tile backer board, cement particle board and non-combustible board. The metal partitioning and ceiling range covers resilient bar, I stud, C stud, U track, MF ceiling systems and wall lining systems, while fixings include hammer fixings, wafer head screws, self-drilling drywall screws and fine and coarse thread collated screws, plus ceiling hangers. Drylining accessories extend to plaster beads, plasterboard adhesive, tape, timber infill, floor protection and sealants, adhesives and foams, with bagged products such as plaster and joint filler.

External facades and building materials

For external work, the catalogue lists cladding and rainscreen insulation (including Rockwool Rainscreen Duo Slab, Kingspan K15 and Knauf Rocksilk Flexible Slab), external render and EWI systems, K Rend products, render boards, plastic and stainless steel render beads and render mesh. The building materials section covers aggregates and cement, sheet materials such as OSB, chipboard and hardwood and softwood plywood, screeding materials and tiling supplies.
