Who says timber windows are high maintenance? 20 years and no touch ups at Kings Cross!


O


ver 20 years ago, plans came to fruition for a large redevelopment of the Kings Cross area of London. The


regeneration of the surrounding buildings became a catalyst for further development and in changing the overall area. Regent’s Quarter was the first area to begin development and this is when George Barnsdale entered the scene,


installing


approximately 350 sliding sash windows and 40 doors to remain in keeping with the history of the area. Two decades later, the outstanding quality of George Barnsdale’s products is evident in how well the windows and doors have stood the test of time. Though some are in need of a good clean, the timber and the paint finish is still perfectly intact despite no recoating having taken place in that time.


“They have very good thermal and acoustic performance even by today’s standards,


with exceptional coating performance. We don’t know of any glazing


unit failures. In the late 90’s we developed a drained and vented glazing system which allows the double-glazed units to perform very well.” Commented Stephen Wright, George Barnsdale.


Exceptional long-term performance


doesn’t only rely on our 4 coat painting process but with good design and paying particular attention to all the smaller details that enhance the life of the coating.

One of the main reasons the products are performing so well after such a prolonged period is the paint process which is an advanced four stage coating system. Superior to most companies’ three stage process, the Barnsdale process provides extra protection to the timber and a superior finish.

Public realm regeneration with permeable paving


A


new case study from Interpave explores


recent urban realm


regeneration projects in Tottenham, London exemplifying the synergy of concrete block permeable paving and street trees to address climate change while delivering SuDS.


It demonstrates important new techniques applicable to all urban areas. The regeneration of White Hart Lane in


north Tottenham, by muf architecture/art, was a pilot designed using ‘Healthy Streets’ principles. But it also applies innovative sustainable drainage (SuDS) techniques introduced by design collaborators Robert Bray Associates.


This approach reduces


flooding and pollution through the integration of bioretention raingardens to collect and treat polluted road runoff. In addition, extensive concrete block permeable paving surfaces not only act as SuDS elements – attenuating and treating rainwater runoff – but also enable essential air/CO2


exchange and optimised water supply for tree roots,


using a range of techniques. A new, concrete block permeable paved, adopted highway accepts runoff from White Hart Lane and other impermeable surfaces. At two points, structural tree pits span the full width below the road surface, connecting road-narrowing tree planters on each side, based on the ‘Stockholm Solution’ for urban tree planting. At the nearby renovation of Broad Lane Square, the same designers take forward these principles with further innovations. In particular, ‘inverted raingardens’ protect existing trees and new green infrastructure, supplied with a gradual supply of clean water from extensive concrete block permeable paving catchments. Concrete block permeable paving – whether full-construction with storage sub- base or applied as an overlay to an existing impermeable road base – works in synergy with trees.


It collects available rainfall,


including away from the canopy, and conveys it to trees and can be used over standard tree

pits, proprietary tree planters, Stockholm System or other structural soil installations. Concrete block permeable paving technology will prove invaluable in delivering the street trees now demanded by planning policies for developments, as well as regeneration.
