# Window Protection Proposal Details

## Typical fixing of polycarbonate window protection

To comply with Diocesan Guidance Notes draft 6 (3/2017) Section 6-20 as used throughout the Isle of Man and in all Dioceses of the Church of England.

To protect windows from damage by weather by protecting with $u / v$ resist polycarbonate sheet cut to shape and secured on hardwood bearers fixed into the render within the window reveal. Use a minimum of 4 mm thick ICI Makrolon or equivalent. Fixing will be with stainless steel screws bearing on stainless steel cup washers, with drainage holes of not less than 8 mm diameter being provided to take away any condensation. Ventilation holes will be fitted at the highest point of a window, not less than 20 mm from the edge and not less than 8 mm in diameter.

PROPOSED POLYCARBONATE WINDON PROTECTION TO NORTH, SOUTH \& WEST ELEVATIONS ST. CATHERINE CHURCH, PORT ERIN FOR
THE VICAR \& NARDENS

Guy J. Thompson Mrics
Job no. 462
November 2019

Fig 1 East end South Transept window - location

Behind this South Transept window is the Meeting Room / Entrance lobby on the ground floor and a storage area on the mezzanine. When rain is driven by a strong easterly wind the water permeates around the lead frame of the old glass and runs down inside the window causing damage to fabric. Rain water enters the fibreglass void above the ceiling of the ground floor and runs across the plasterboard ceiling eventually dripping down on the carpet below. Overnight, water can half fill a two gallon bucket.

Good quality polycarbonate sheeting over the glazed area onto hardwood frames secured into the sides of the window recess would prevent this reoccurring damage. We propose to use a minimum of 4 mm thick ICI Makrolon or equivalent. Fixing will be with stainless steel screws bearing on stainless steel cup washers, with drainage holes of not less than 8 mm diameter being provided to take away any condensation. Ventilation holes will be fitted at the highest point of a window, not less than 20 mm from the edge and not less than 8 mm in diameter. This work would be compliant with the Diocesan Guidance Notes draft 6 (3/2017) Section 6-2017HUL

Work access would be from outside the building and scaffolding will be required

Glazed area is approximate $3^{\prime} 6^{\prime \prime}$ wide $\times 9^{\prime}$ high. Clear glass is just 1 mm thick and prone to cracking or breakage

West facing window in tower
Needing protection from wind and rain
Behind this west facing window are wooden steps leading to the tower. When there is a westerly or SW wind accompanied by rain (frequently !) the water enters the building and the tower steps run with water causing damage to internal walls. The steps are the only access to the tower and frequently used by the Government Telecommunications Division to access their equipment cabin located in the tower. This access is available $24 / 7$ and is for the emergency services essential TETRA system.

Good quality polycarbonate sheeting over the glazed area onto hardwood frames secured into the sides of the window recess would prevent this reoccurring damage. We propose to use a minimum of 4 mm thick ICI Makrolon or equivalent. Fixing will be with stainless steel screws bearing on stainless steel cup washers, with drainage holes of not less than 8 mm diameter being provided to take away any condensation. Ventilation holes will be fitted at the highest point of a window, not less than 20 mm from the edge and not less than 8 mm in diameter. This work would be compliant with the Diocesan Guidance Notes draft 6 (3/2017) Section 6-20.
