Homes in Glenageary and how we insulate them
Glenageary is a mature, tree-lined residential suburb developed primarily during the early to mid-20th century. The local housing stock features substantial 1930s to 1950s bay-windowed semi-detached houses, red brick and pebble-dash family homes, 1960s detached houses around Silchester Park and Adelaide Road, and later cul-de-sac developments off Glenageary Road Upper [CONFIRM housing stock].
A significant proportion of Glenageary homes were built using solid concrete blockwork or narrow uninsulated cavity walls. The original pebble-dash finishes frequently show hairline cracking after decades of exposure, allowing moisture penetration and heat loss. Homeowners frequently report chilly front rooms, cold drafts around bay windows, and persistent winter heating demands.
Applying a complete external wall insulation envelope using 100mm to 150mm Baumit EPS insulation board revitalises these homes. The continuous insulation layer covers existing cracked pebble-dash, eliminates thermal cold bridges around concrete window lintels and floor joists, and transforms the exterior with a modern, crack-resistant silicone render.
Conservation areas and planning in Glenageary
Planning governance in Glenageary falls under Dún Laoghaire-Rathdown County Council. The area includes the Silchester Road Architectural Conservation Area (ACA), which was established to preserve Victorian and Edwardian residential character, mature gardens, and distinctive road layouts. Outside designated ACAs, the vast majority of suburban Glenageary estates enjoy exempted development status.
For standard houses on roads such as Glenageary Park, Arnold Park, and Park Road, external wall insulation does not require planning permission, provided the system does not project across property boundaries and the render finish harmonises with the surrounding area. Dwellings on the Record of Protected Structures or inside the Silchester Road ACA require planning consultation before altering facade materials.
Isotherm confirms the planning status of every Glenageary property prior to contract signing, ensuring all works conform to Dún Laoghaire-Rathdown guidelines. For detailed information, consult our guide to planning permission for external insulation.

Frequently asked questions in Glenageary
Can external wall insulation be applied over existing Glenageary pebble-dash?
Yes. Our direct crews wash and inspect existing pebble-dash, secure any loose render, and fix Baumit EPS insulation board using high-strength adhesive mortar and heavy-duty mechanical fixings anchored into the solid masonry core.
How do you handle bay windows on Glenageary semi-detached homes?
Bay windows require specialist thermal detailing. We insulate around all angles, fit bespoke insulated reveal returns, and install custom-angled aluminium window cills from Cills.ie to guarantee watertight drainage.
Will external insulation improve my Glenageary homes BER rating?
Yes. Upgrading solid block or poorly insulated walls with a 120mm Baumit wrap typically improves the BER by two to three full bands, for example jumping from an E1 or D2 rating to a warm, energy-efficient B2 or A3.
