Loft Insulation & Celotex (PIR) Board Fitting in Portsmouth & Surrounding Areas

With heating costs continuing to rise, an uninsulated or poorly insulated loft is one of the biggest sources of heat loss in any home. Up to of a house’s heat escapes directly through an unprotected roof. At TK Handy Services, we install high-performance loft insulation—from traditional mineral wool rolls to high-efficiency rigid PIR boards (like Celotex and Kingspan)—to trap warmth, drop your energy bills, and make your home instantly more comfortable.

Whether you need a simple loft top-up to meet energy standards, solid Celotex insulation between rafters, or a fully insulated and boarded loft space for clean storage, we deliver neat, professional fitting with zero hassle.

Our Loft Insulation & Celotex Fitting Services

  • Celotex & Rigid PIR Board Installation

    • Precision cutting and fitting between roof rafters to maximize headroom and retain heat.

    • Installing Celotex boards over timber joists to eliminate thermal bridging cold spots.

    • Foil-taping all insulation joints and seams to build a continuous, airtight vapour barrier.

    • Ideal for timber-frame structures, loft conversions, and converting cold roofs into warm spaces.

  • Traditional Roll Insulation Top-Ups

    • Laying thick glass-mineral wool insulation rolls between joists and crisscrossing a second layer to reach the modern depth standard.

    • Topping up old, compressed, or inadequate existing insulation without removing usable materials unnecessarily.

    • Fitting pre-cut insulation rolls cleanly around hatch frames, chimney breasts, and structural beams.

  • Loft Boarding & Raised Storage Solutions

    • Fitting raised "loft legs" over deep insulation to prevent compressing the material (which ruins its efficiency).

    • Installing tongue-and-groove chipboard loft flooring to create strong, walkable storage platforms.

    • Creating custom access walkways from your hatch to water tanks or storage zones.

  • Ventilation, Pipe & Hatch Protection

    • Installing soffit eaves vents and rafter baffles to ensure continuous airflow and prevent damp or condensation buildup.

    • Insulating and draught-proofing loft hatch covers to eliminate cold drafts leaking into top-floor rooms.

    • Lagging exposed hot/cold water pipes and wrapping header tanks to protect against winter freezes.

Why Choose Celotex (PIR Board) Insulation?

  • Maximum Heat Retention in Less Space: Rigid PIR boards like Celotex deliver exceptional thermal resistance at half the thickness of traditional wool rolls—ideal where height or space is tight.

  • Durable & Moisture-Resistant: Celotex boards won't sag, compress, or absorb dampness over time, retaining their insulation performance for decades.

  • Built-in Vapour Shield: The composite foil facings on Celotex act as a built-in barrier against internal draft and moisture migration.

The TK Handy Services Difference

  • Correct Airflow Guaranteed: Insulation only works if your roof can breathe. We strictly maintain eave ventilation gaps to stop moisture, mould, and timber decay.

  • Clean, Tidy Workmanship: Rigid insulation cutting generates dust—we protect your landings, seal work areas, and vacuum thoroughly after fitting.

  • No Upfront Guesswork: Upfront, honest pricing based on square footage and material requirements with zero hidden extras.
