Howells Patent Glazing has supplied two new rooflights for the conservation and redevelopment of Shrewsbury Flaxmill Maltings.
The most dramatic of the two installations is the flat rooflight which sits above the iconic Grade II listed Kiln. To maximise the natural light levels, Howells designed a large 2m x 2m aluminium flat rooflight with double glazing.
The rooflight is fixed to four upstand kerbs that were prepared by others during the reconstruction of the distinctive pyramid roof. It achieves a 1.0 W/m 2 K U-value and contributes to the building’s thermal performance.
A second rooflight was specified for the space which connects the adapted Kiln and North Engine House and the existing Cross Mill.
The rooflight with thermal barrier is constructed from aluminium glazing bars with four panes of glass. It is designed and manufactured in accordance with BS 5516 and BS 1474.
Due to the five degree pitch and location of the self-supported rooflight, Howells selected Class 2 non- fragility glazing. It was glazed onsite using 28mm double glazed units with a 6mm toughened and Easy Clean outer pane and 9.5mm clear inner pane. Once again, the centre pane achieves a 1.0 W/m 2 K U-value.
Both aluminium rooflights are powder coated in Jet Black. This protective and decorative layer offers exceptional resistance to weathering, corrosion and wear, ensuring longevity and minimal maintenance.
