About PinecresthHome

What this site covers

PinecresthHome is a subject-specific reference covering wood fibre insulation materials, installation methods in timber frame walls, and the thermal performance requirements that apply to wooden houses under Polish building law.

The content is oriented toward construction professionals, architects, and owner-builders who need factual, regulation-aware information rather than promotional descriptions. All data referenced here comes from publicly available product declarations, European standards, and Polish building regulations.

Scope of coverage

The three main subject areas addressed are:

• Board specifications — density ranges, thermal conductivity values, compressive strength, reaction to fire classification, and CE marking obligations under EN 13171.
• Installation in timber frame systems — layer sequencing, vapour diffusion management, mechanical fixing, and typical assembly errors in stud wall construction.
• Polish thermal regulations — the requirements introduced by the Warunki Techniczne 2021 (WT 2021) amendment, U-value limits by building element, and the calculation approach defined in PN-EN ISO 6946.

Standards and sources

Where numerical values appear, they reference European harmonised standards (EN 13171, EN ISO 6946, EN ISO 13788) or the text of Polish building regulations. No figures are presented without a traceable basis. Where a range reflects market variation rather than a single standard, this is noted explicitly.

External links point to the Polish Ministry of Development, the Instytut Techniki Budowlanej, and the European Commission's energy efficiency resources.

What this site does not provide

This site does not offer project-specific design advice, structural calculations, or regulatory compliance opinions. Decisions about insulation specification, wall assembly design, or energy certification must be made by a licensed building designer under Polish law (Prawo Budowlane, Ustawa z dnia 7 lipca 1994 r.).
