A combination of Protect construction membranes has been supplied and installed at Glasdir School, a modern school building constructed to BREEAM Excellent standards using BIM Level 2.

Built by Wynne Construction and designed by architects Lovelock Mitchell, this £10.5 million project involved re-locating two primary schools to a brand new shared site in Ruthin, delivering a complete solution to client Denbighshire County Council as part of the Welsh Government’s 21st Century Schools and Education Programme.

Manufactured offsite by construction specialist Innovaré using their advanced i-SIP technology, an independently accredited Structural Insulated Panel System (SIP), the resulting structure was both water and airtight, delivering thermal efficiency to a final U-value of 0.15w/m2k. The structure led to Innovare being the winners of the Best Use of SIPs category at the 2018 Structural Timber Awards.

Protect’s TF200 external breather membrane was used externally on the SIP to ensure high water resistance and vapour permeability, minimising the risk of interstitial condensation in the wall structure. Internally, Protect BarriAir was used to ensure the integrity of airtightness and to significantly reduce heat loss and air leakage through the building fabric.

Craig Lee, Supply Chain Manager at Innovaré commented “Over 10,000m2 of i-SIP components including internal and external walls and roof cassettes were erected by Innovare in only 13 weeks, 55% faster than traditional build. By using Protect’s membranes we have peace of mind, both in long term performance as well as timely deliveries, which helped us to maximise the speed benefits of offsite construction.”

A variety of wall construction membranes, roofing underlays and accessories from Protect has been installed into an innovative new modular concept manufactured by Tingdene Homes, holiday and park home specialists.

Offered under the THL Modular branding, The Loft is a contemporary two-storey holiday home designed and manufactured completely offsite in Tingdene Homes’ factory, using cutting edge design and high end specification to meet the needs of the growing “staycation” market. Fully LABC product approved and constructed to UK Building Regulations, The Loft can be built to suit varied client needs ranging from a two or three bedroom luxury lodge to a two or four room hotel pod, club house or café. A number of Protect products were supplied and installed on THL Modular’s first show home, including Protect BarriAir, an internal airtightness membrane, Protect VC Foil Ultra used as the insulating low emissivity vapour control layer, Protect TF200 Thermo insulating low emissivity breather membrane for external walls and Protect VP400 Plus LR, a roofing underlay offering unrestricted wind uplift resistance, and exceptional vapour permeability.

Phil Harold, Quality Assurance Manager at Tingdene Homes commented “The use of numerous Protect products for this development helped us meet specification and achieve our target U-values of 0.18 W/m2K for external walls and 0.14W.m2K for the roof element. With the numerous benefits of offsite manufacture over traditional construction including build speed, quality precision and reliability, we wanted a supplier who understood these principles to ensure our delivery demands were met. Protect supplied products quickly which enabled our process to run without interruption and facilitated swift turnaround at the factory.”

Protect’s range of wall, ceiling and floor construction membranes together with its roofing underlays and accessories provides a comprehensive solution to the modular build sector. In particular, Protect construction membrane products with reflective technology help deliver thermal efficiency benefits to meet low target U-values and ensure compliance with relevant Building Regulations.
