Wraptite®: Wraptite is an external self-adhesive vapour permeable air barrier for walls, roofs and floors to achieve good airtightness results. The Wraptite range of external air barriers ensures reliable airtightness in buildings with a two-component system: Wraptite and Wraptite Tape. This approach reduces labour and material costs for both commercial and residential projects by relocating the air barrier to the building's exterior, minimizing penetrations and eliminating the need for expensive specialized components. Wraptite is highly vapor-permeable, airtight, and self-adhering, ensuring a consistent external seal. Wraptite has two BBA certificate for use in walls, roofs and floors.

Proctor Air®: Proctor Air® is an air and vapour permeable pitched roof underlay which allows vapour to escape- but also allows air in- reducing condensation risk. Proctor Air® is a highly water-resistant, air, and vapor permeable roofing underlay. Its design allows complex pitched roofs to breathe without air gaps or extra venting. The meltblown core facilitates natural air movement, enhancing moisture vapor passage and reducing condensation. Proctor Air® features include vapor permeability, full air permeability, water resistance, compliance with BS5534 wind uplift resistance standards, provision of more uniform airflow compared to vents, elimination of the need for a vapor control layer (VCL), a 15-year warranty, and certification by the British Board of Agrément (BBA).

Procheck A2®: Procheck A2® is a vapor and airtight membrane with a Class A2-s1, d0 fire classification, making it non-combustible. Constructed with a glass fibre backing, aluminium foil, and a clear lacquer coating, it offers high vapor control properties and airtightness, suitable as an AVCL in construction to enhance thermal efficiency. Procheck® A2 key features include Class A2-s1, d0 fire classification, high vapor resistance, a low emissivity clear lacquered aluminium surface, reflective material with emissivity below 0.05, durability for tough site conditions, and BBA certification.

Procheck FR200®: Procheck FR200® functions as a vapor control layer in roofs and walls for new and renovation projects. With a B-s1, d0 Reaction to Fire classification, it ensures reliable fire performance. This air and vapor tight membrane also improves energy efficiency and reduces condensation risk. Procheck FR200's key attributes include independently verified fire performance with an EN 13501-1 B-s1, d0 classification, enhanced energy efficiency, reduced risk of condensation, and a reinforced membrane that withstands tough site conditions.

Proctorwrap Reflect®: Proctorwrap Reflect® is a low emissivity, vapor permeable membrane that enhances the thermal performance of timber and steel frames. Made from non-woven polypropylene foil laminate, it provides breathability and protection during construction. Installed on the external face of the frame, it meets TRADA and NHBC vapor resistance standards with an Sd 0.08m / 0.4 MNs/g. Cover within 3 months and repair any damage immediately. Proctorwrap Reflect® features an R value of 0.71, competitive pricing, enhanced foil surface, low vapor resistance compliant with TRADA and NHBC, high strength-to-weight ratio, W2 water penetration rating, and availability in 1.5-, 2.7-, and 3-meter-wide rolls.

Reflectatherm® Plus: Reflectatherm® Plus is a high resistance, reflective air and vapor control layer for internal walls, ceilings, and floors, enhancing thermal performance when placed on the warm side of insulation. Reflectatherm® Plus boasts high vapor resistance and improved airtightness, offers an R value of 0.72 m² K/W with a 19mm service cavity, creates an unbroken vapor control layer, and has an Sd value greater than 150m. Install with the foil side facing the cavity, overlap sheets by 150mm, and seal all joints.
