Protect installed in award winning education project

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 Governments 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.

Protects 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 Protects 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.”
